Story at-a-glance
- Research shows that “blowing off steam” through intense physical activity doesn’t reduce anger and may actually increase it, contradicting popular belief about anger management
- Calming techniques like meditation, mindfulness, relaxation and yoga are significantly more effective at reducing anger, hostility and aggressive behavior
- Combining cognitive strategies with physical calming practices produces stronger results than either approach alone, suggesting both body and mind need attention
- Mindfulness increases self-awareness and emotional control by activating brain regions that regulate emotions, helping you interrupt the anger cycle before it escalates
- Regular practice of relaxation techniques helps lower baseline stress levels and prevents anger outbursts, providing long-term benefits for both mental and physical health
You’ve probably heard that letting off steam by hitting a punching bag or going for a run helps you cool down when you’re angry. But recent evidence says otherwise. A review published in Clinical Psychology Review found that these approaches don’t just fail to reduce anger — they might make it worse.1
That’s a problem, because anger isn’t just uncomfortable. It’s dangerous. While anger is a normal emotion, it becomes a serious threat to your health and relationships when you don’t have the tools to calm it down. Instead of “blowing off steam,” you need to cool the system down. Let’s look at the science behind what really works to settle down when you’re overwhelmed by anger.
Calming Down Is Better Than Blowing Off Steam
A large-scale meta-analysis published in Clinical Psychology Review reviewed 154 studies involving 10,189 participants to uncover what actually works for reducing anger.2
The goal was to evaluate the effectiveness of activities that either increase or decrease bodily alertness — things like hitting a punching bag or going for a jog versus meditation or intentional breathing. The popular belief that venting helps you feel better didn’t hold up. In fact, the opposite was true. Only calming, arousal-reducing activities consistently helped.
• Anger dropped significantly in those who practiced calming techniques — The researchers found that calming activities like breathing exercises, meditation, and yoga led to a large reduction in anger. In contrast, activities that increased arousal had no meaningful effect on anger or aggression. In other words, trying to “let it out” by doing something intense didn’t help.
• Anger, hostility and aggression all improved with calming interventions — The data showed that these calming methods didn’t just reduce angry feelings — they also lowered hostility, which is the mental attitude behind anger, and aggressive behavior — how that anger gets expressed.
• Time didn’t reduce the effectiveness of calming methods — Calming methods worked regardless of how long the session was or how many sessions someone completed. Whether the intervention was a single 20-minute guided breathing practice or a longer multi-week meditation program, the effect remained stable. So, if you’re pressed for time, even short sessions make a difference, as long as they help you slow down rather than rev up.
Meditation and Mindfulness Deliver the Strongest Benefits
Not all calming techniques worked equally. Meditation delivered the strongest results, followed by mindfulness, relaxation and yoga. This shows structured practices that help you focus your mind and body — not just passive rest — have a powerful effect on cooling down your internal state.
• Combining cognitive and calming strategies produced stronger results — Activities that combined a calming physical experience, like slowing your breath, with a cognitive process, like focusing your thoughts or practicing kindness, were more effective than physical relaxation alone.
Cognitive-focused interventions lowered anger more than arousal-only approaches. This suggests that your mindset matters — calming your body helps, but calming your thoughts amplifies the effect.
• Arousal-increasing activities failed to reduce anger and even made it worse — Dealing with anger physically didn’t help. Whether it was punching a bag, doing martial arts or going for a run, these arousal-increasing methods had little or no impact on anger levels. In some cases, they made things worse.
For example, jogging was associated with an increase in anger. Stair climbing and rowing also showed trends toward increased anger, while only ball sports and aerobic group activities produced slight improvements. But the majority of these intense, energizing activities failed to bring emotions down.
• Jogging may increase anger by fueling frustration — Researchers noted that jogging might raise anger because of its repetitive nature. It may not offer enough mental stimulation or emotional release, which makes frustration worse instead of better. Some people also feel trapped or powerless while jogging — like on a treadmill — which feeds feelings of irritation or stress.
• Relaxing techniques lower heart rate and engage the parasympathetic nervous system — While the study didn’t dig deeply into biological mechanisms, the known science behind relaxation helps explain why it works.
Calming practices stimulate your parasympathetic nervous system — also called the “rest and digest” branch — which helps slow your heart rate, lower blood pressure, and ease muscle tension. This shuts off the fight-or-flight response that fuels anger and aggression.
• Mindfulness increases self-awareness and emotional control — Mindfulness — intentionally paying attention to the present moment — activates parts of your brain that help regulate emotion. When you practice it regularly, you gain more control over impulsive reactions and develop more patience. It builds what psychologists call “self-efficacy,” or your belief that you can manage your feelings and actions effectively.
Use Relaxation to Interrupt the Anger Loop
You don’t have to be at the mercy of your anger. You can stop the stress response before it spirals out of control — but to do that, you need to interrupt the cycle early. When you feel your body revving up, your breathing changing or your shoulders tightening, that’s your signal to act. The research is clear: the more you try to blow off steam, the more pressure you build. The only reliable path out is through relaxation.
Your goal is to reduce your physiological arousal — the state of high energy and tension that primes you to lash out. Whether you’re dealing with everyday irritations or chronic anger that affects your relationships and health, these strategies give you tools to regain control. Below are five steps you can take to cool your nervous system and calm your mind.
1. Shift from reaction to awareness with mindfulness — If you’re a person who reacts quickly when upset, learning mindfulness will help you notice what’s happening before you explode. That’s your opportunity to choose a different response. Mindfulness means paying attention to your thoughts, body, and feelings without judging them.
Try to observe your breath or sensations for five minutes a day. This gives your brain space to reset and reduces emotional reactivity over time.
2. Use intentional breathing to lower your internal pressure — Instead of taking deep, vertical breaths that trigger the stress response, practice horizontal breathing. This means expanding your ribcage sideways rather than lifting your chest upward. Horizontal breathing promotes relaxation by avoiding the activation of stress pathways in your nervous system.
Do this for a few minutes, especially when you notice frustration building. You’ll likely feel your heart rate slowing and your shoulders dropping. This is your body exiting the fight-or-flight state that fuels anger.
3. Try meditation to retrain your stress response — If you struggle with persistent anger or resentment, meditation is a valuable long-term strategy. The research found it was the most powerful calming tool available.
You don’t have to do anything fancy — just sit quietly, close your eyes and focus on your breath or a calming word. Guided meditations are helpful if you’re just getting started. Aim for 10 minutes a day. Over time, this rewires how your brain handles stress and improves emotional control.
4. Use movement wisely to release — not increase — tension — If you’re someone who usually punches a bag or goes for a hard run to deal with anger, be aware that those high-intensity efforts could make it worse. Instead, try yoga, walking in nature, or gentle stretching. These movements help lower adrenaline and cortisol, the hormones that drive your internal storm. They also keep your body active while allowing your nervous system to calm.
5. Practice regular relaxation before the anger hits — If your stress builds over the day and then explodes, you’re not alone — but you don’t have to wait until the pressure gets too high. Build calming routines into your life daily, such as listening to calming music, doing progressive muscle relaxation, taking a quiet walk after work, or sitting on your porch without your phone.
The key is consistency. You’ll start to notice that your baseline anger level drops, and you’ll have more space to respond instead of react. When you calm your body, you calm your mind. And when your mind is calm, you take back control over your choices. That’s how real change starts.
FAQs About Anger
Q: How does anger affect my health if I don’t deal with it properly?
A: Uncontrolled anger activates your fight-or-flight stress response, which raises your heart rate, blood pressure, and adrenaline. Over time, this state of constant arousal increases your risk of heart disease, weakens your immune system and contributes to chronic inflammation. It also harms relationships and decision-making.
Q: Is venting or “blowing off steam” actually helpful for anger?
A: No. Contrary to popular belief, venting makes anger worse. According to the Clinical Psychology Review, venting — through yelling, punching pillows or aggressive workouts — tends to reinforce angry behavior and increase hostility rather than reduce it.
Q: What’s the most effective way to calm down when I’m angry?
A: The most effective approach is to calm your body through relaxation techniques like intentional breathing, meditation, and mindfulness. These practices reduce physiological arousal and interrupt the anger cycle. Over time, they help rewire your brain to handle stress more calmly.
Q: What type of exercise helps with anger control?
A: Low-arousal movement like yoga, walking, or stretching is ideal. High-intensity workouts — like running or boxing — actually increase anger for some people. Choose movement that soothes rather than stimulates.
Q: How often should I practice these techniques to see results?
A: Daily practice is key. Even five to 10 minutes of mindfulness or relaxation each day helps lower your baseline stress and makes you less reactive. You don’t need to wait until you’re angry — using these tools consistently helps prevent outbursts before they start.
Exercise Triggers More Brain-Boosting Protein in Fit People

Analysis by Dr. Joseph Mercola April 18, 2026
Story at-a-glance
- Your brain produces more of a key growth protein during exercise only after your fitness improves, meaning the same workout becomes more powerful for your focus and mental clarity over time
- A 12-week training period is the tipping point where your brain begins responding more strongly, so short bursts of exercise without consistency fail to deliver full cognitive benefits
- Higher fitness levels lead to faster thinking, better attention, and improved decision-making during and after exercise, directly improving how you perform in daily tasks
- The biggest brain benefits occur during exercise itself — not at rest — showing that pushing your body appropriately activates real-time improvements in brain function
- Starting with simple, consistent movement like daily walking builds the foundation your brain needs to unlock stronger responses, making long-term consistency more important than intensity
If you’ve ever finished a workout and wondered why your mind still feels foggy instead of sharp, your fitness level may be the reason. A 2026 study published in Brain Research found that your brain doesn’t respond to exercise the same way when you’re out of shape.1 Exercise triggers the release of brain-derived neurotrophic factor (BDNF), a protein that works like fertilizer for your brain.
Just as fertilizer helps roots grow stronger and deeper, BDNF strengthens the connections between brain cells, helping you think more clearly, focus longer, and adapt faster. But how much BDNF your brain produces during a workout depends heavily on your fitness level. For anyone dealing with mental fatigue, poor focus, or slower thinking, this insight hits close to home.
You read the same paragraph three times. You lose your train of thought mid-sentence in a meeting. You reach for coffee at 2 p.m. not because you’re tired, but because your brain feels like it’s running through mud. These symptoms often reflect reduced efficiency in the prefrontal cortex, the part of your brain that handles concentration, impulse control, and complex tasks. When this system underperforms, daily work feels harder, distractions increase, and decision-making suffers.
Left unchecked, this decline in cognitive sharpness affects productivity, mood, and long-term brain resilience. What becomes clear is that exercise alone isn’t the full story — your level of fitness determines how powerful that exercise becomes for your brain. Here’s what the research found — and why it changes the way you should think about every workout.
Getting Fitter Rewires How Your Brain Responds to Exercise
The Brain Research study followed sedentary adults through a 12-week cycling program to see how exercise changes the brain’s response to physical activity.2 Researchers tracked three things simultaneously: BDNF levels, cognitive performance, and real-time brain activity using neuroimaging. The goal was to find out whether getting in shape changes how your brain reacts during exercise, not just over time but in the moment you move.
The study included adults who exercised less than 30 minutes a day and placed them into two groups: one completed a structured cycling program, while the other stayed inactive. The training group gradually increased intensity from light to more demanding sessions.
By the end, their cardiovascular fitness improved significantly, as measured by VO2 max — essentially a score for how efficiently your heart, lungs, and muscles use oxygen during exertion. The higher your VO2 max, the more capacity your body has to fuel both physical and mental performance. The control group showed no improvement. That distinction set up a clear comparison between a “trained” and “untrained” brain response.
• Fitness changed how strongly the brain responded during exercise — The biggest shift appeared not at rest, but during exertion. After 12 weeks, the trained group showed a significant increase in serum BDNF only after intense exercise, not before it.
This means your brain doesn’t upgrade its response until you build a stronger engine. The more fit participants became, the larger the spike in this brain-supporting protein when they exercised. Researchers confirmed this link by showing a direct correlation between improved fitness scores and higher BDNF increases.
• Higher fitness translated into measurable brain performance changes — Alongside these biological changes, participants improved how their brains handled tasks that require focus and control. Reaction times dropped, meaning faster thinking, and performance improved on attention and inhibition tasks — the kind of mental skills you rely on to stay focused and avoid distractions.
These gains showed up consistently after exercise sessions — direct evidence that a fitter body produces a sharper mind in real time. Using brain imaging, the study also tracked activity in the prefrontal cortex — the area responsible for decision-making, attention, and impulse control.
As BDNF increased, activity patterns in this region shifted during tasks that required focus and inhibition. In plain terms, your brain became more efficient at handling demanding mental work after exercise, especially once you were fitter.
• Timing mattered — results only appeared after consistent training — Interestingly, the benefits didn’t show up halfway through the program. At week 6, there was no meaningful connection between fitness gains and BDNF response. During those early weeks, your body is building the cardiovascular infrastructure, like stronger blood vessels, more efficient oxygen delivery, and improved mitochondrial function, that eventually allows your brain to produce a stronger BDNF response.
Only after the full 12 weeks did the effect become clear. That tells you something important: your brain doesn’t always respond instantly to lifestyle changes. It adapts gradually, and the payoff comes after sustained effort. If progress feels slow early on, that is part of the process, not a failure.
• The strongest effects showed up in those who improved the most — Participants who reached higher fitness levels saw the largest increases in BDNF after exercise. This creates a self-reinforcing cycle: higher fitness triggers a stronger brain response, which sharpens your thinking and focus, which makes staying consistent with training feel less like willpower and more like momentum. You aren’t just building endurance — you’re building a brain that responds more efficiently to every effort.
• Different forms of this brain protein serve different roles — The researchers measured two types of BDNF: plasma BDNF and serum BDNF. Think of plasma BDNF as your brain’s quick-release dose — it spikes right after you move. Serum BDNF reflects your body’s deeper reserves, how much of this protein your system is capable of manufacturing and storing. The key finding was that fitness expanded those reserves, so fitter people had a bigger supply to draw from each time they exercised.
BDNF supports several key processes inside your brain: it improves blood flow, strengthens connections between brain cells, and supports energy production at the cellular level. As your fitness improves, your body amplifies this response, delivering more resources to the parts of your brain that handle complex thinking. That is why the same workout produces stronger mental benefits once you’re in better shape.
Build Your Fitness to Unlock Your Brain’s Full Potential
So, what does this mean for your daily routine? Your brain doesn’t fully respond to exercise until your body reaches a higher level of fitness. That’s the root issue. If your workouts are inconsistent or your mental clarity doesn’t improve, the missing piece isn’t effort — it’s adaptation.
Once your fitness improves, your brain produces stronger signals that sharpen focus, speed up thinking, and improve control. That means the goal isn’t random exercise. The goal is building capacity over time so your brain starts working with you instead of against you.
1. Commit to a 12-week progression, not random workouts — If you jump between routines or stop after a few weeks, your brain won’t reach the point where it upgrades its response. The research shows the real shift happens around the 12-week mark. Set a simple rule: train consistently for three months before judging results. Track your sessions like a scoreboard. Each completed workout is a point. The goal is consistency, not perfection.
2. Train across intensities to improve your results — Your brain responds more when your body faces a range of demands. Include low, moderate, and high-effort sessions each week. For example, mix easy sessions where you can talk comfortably with harder sessions where your breathing becomes heavy.
A routine that includes walking, strength training, heart-rate-raising movement, and coordination provides full-body benefits. This variety pushes your system to adapt, which strengthens the brain response tied to focus and decision-making.
3. Measure progress using effort and capacity, not just time — Fitness isn’t about how long you move — it’s about how your body performs. Pay attention to how hard a workout feels and how quickly you recover. If you notice that the same workout feels easier over time, your fitness is improving. That improvement is what drives the stronger brain response seen in the research.
4. Start with walking and build gradually without overdoing intensity — Daily walking works as a powerful entry point because it improves mood regulation and energy production without placing excessive stress on your system. If you’re new to exercise, start small. Add five minutes each week until you reach 30 minutes, then hold that level for a month before building toward one hour a day.
Avoid pushing intense exercise too frequently. Pounding yourself with hard workouts too often backfires and slows progress.
5. Use post-exercise focus as feedback that you’re on the right track — After a workout, pay attention to how your mind feels. Sharper thinking, better focus, and quicker reactions signal that your brain is responding. Early on, this effect might feel weak. As your fitness improves, it becomes stronger and more noticeable.
That is your real-time proof that your efforts are working. Stick with this long enough and your workouts stop feeling like a chore. They become a tool that sharpens how you think, how you make decisions, and how you perform every day.
FAQs About How Exercise Improves Your Brain Function
Q: Why doesn’t exercise improve my brain function right away?
A: Your brain doesn’t upgrade its response immediately because it depends on your fitness level, not just the act of exercising. The research shows that stronger brain benefits — including higher BDNF release — only appear after consistent training over about 12 weeks. Early workouts still matter, but the real shift happens once your body adapts and becomes more efficient.
Q: What is BDNF and why does it matter for my brain?
A: BDNF is a protein that supports brain cell growth, communication, and energy use. It acts like a signal that helps your brain become faster, sharper, and more resilient. Higher levels during exercise are linked to better focus, quicker thinking, and improved control over distractions.
Q: How does being more fit change the way your brain works?
A: As your fitness improves, your brain produces a stronger BDNF response during exercise. This leads to better performance on tasks that require attention, decision-making, and impulse control. The same workout becomes more powerful for your brain once you’re in better shape.
Q: How long does it take to see real brain benefits from exercise?
A: The study found no meaningful changes halfway through the program at six weeks. The major improvements showed up after 12 weeks of consistent training. This timeline highlights that your brain adapts gradually, and the benefits build over time with steady effort.
Q: What’s the best way to start improving brain benefits from exercise?
A: Start with consistent movement and build gradually. Daily walking is an effective entry point because it improves energy and mood without overwhelming your system. As your fitness improves, add variety and intensity in a balanced way. The key is staying consistent long enough for your brain to adapt and respond more strongly.
Disease Categories with Strong Evidence for Molecular Hydrogen Therapy

https://articles.mercola.com/sites/articles/archive/2026/03/26/molecular-hydrogen-therapy.aspx
Analysis by Dr. Joseph Mercola March 26, 2026
Story at-a-glance
- Molecular hydrogen therapy is gaining scientific attention because it selectively neutralizes the most damaging reactive oxygen species that drive cellular damage, inflammation, and many chronic diseases
- Clinical research analyzing dozens of human trials found hydrogen therapy shows benefits across several major disease categories, including cardiovascular disease, cancer, respiratory disorders, and neurological injuries
- Hydrogen’s extremely small molecular size allows it to penetrate biological membranes and reach areas many drugs can’t access, including your brain and the mitochondria that produce your cellular energy
- Studies show hydrogen inhalation and hydrogen-rich water improve measurable health markers such as blood vessel function, inflammation levels, breathing performance, and neurological recovery after brain injury
- Using hydrogen therapy alongside lifestyle strategies that reduce oxidative stress — such as eliminating seed oils, avoiding alcohol, getting regular sunlight, and supporting your metabolism with adequate carbohydrates — strengthens cellular repair and improves overall resilience
More than 2,000 scientific papers now examine molecular hydrogen — a gas researchers once dismissed as biologically inert. That assumption held for decades until studies began revealing that hydrogen interacts directly with the reactive oxygen species responsible for cellular damage, inflammation, and chronic disease.
Your body produces reactive oxygen species — unstable molecules that damage your cells — naturally during energy metabolism. They’re a normal byproduct of being alive. But modern exposures accelerate their production far beyond what your defenses can handle. Pollution, ultraprocessed foods, toxins, and chronic illness all push your body toward oxidative stress — a state where damage outpaces repair.
This imbalance contributes to heart disease, cancer, neurodegenerative disorders, and metabolic dysfunction, making it one of the central problems in modern medicine. Most supplemental antioxidants work indiscriminately — they suppress harmful oxidants but also knock out the beneficial ones your cells use for signaling and immune defense.
Molecular hydrogen works differently, and the clinical research now emerging helps explain why scientists view it as one of the more promising therapeutic tools under investigation.
Molecular Hydrogen Therapy Influences Multiple Disease Systems
A scientific review published in the journal Molecules examined clinical research on molecular hydrogen therapy and evaluated its therapeutic effects across a wide range of diseases.1 The researchers analyzed 81 registered clinical trials and 64 peer-reviewed human studies investigating hydrogen administration through methods such as inhalation, hydrogen-rich water, and hydrogen-infused saline.
The goal of the review was to determine whether hydrogen gas could emerge as a viable medical therapy and identify which diseases respond most strongly to it. The researchers also explored the safety of hydrogen administration and how delivery methods influence outcomes in real-world clinical settings.
• Hydrogen therapy studies span heart disease, cancer, and brain disorders — Participants in the analyzed studies included patients with cardiovascular disease, cancer, respiratory illness, neurological disorders, autoimmune disease, metabolic conditions, and fatigue-related disorders. Researchers also examined hydrogen therapy in athletes, people with obesity, and patients recovering from severe infections.
Across these diverse groups, the researchers repeatedly observed improvements in markers of oxidative stress, inflammation, and metabolic function. Hydrogen’s benefits appear strongest in diseases driven by excessive oxidative stress — meaning conditions where unstable molecules damage tissues and disrupt normal cellular function.
• Cardiovascular studies revealed measurable improvements in heart and blood vessel function — In one early study, patients inhaled 2% hydrogen gas alongside standard temperature management therapy following cardiac arrest.2
The group receiving hydrogen experienced significantly higher 90-day survival rates compared to the control group receiving standard care alone. Researchers also recorded improvements in neurological outcomes, meaning patients retained better brain function after oxygen deprivation events associated with cardiac arrest.
• Other cardiovascular trials showed hydrogen improved blood vessel performance — Another clinical study examined how hydrogen-rich water affected endothelial function — the ability of blood vessels to expand and contract properly.
Participants who consumed water containing about 7 milligrams (mg) of dissolved hydrogen per liter showed significantly improved flow-mediated dilation compared to those receiving placebo water.3 Flow-mediated dilation measures how well arteries widen in response to blood flow, and impaired dilation is a warning sign of cardiovascular disease. Improved dilation indicates healthier blood vessel function and better circulation.
• Cancer research revealed hydrogen therapy influences immune activity and treatment tolerance — One clinical study involving 58 patients with advanced non-small cell lung cancer reported that patients receiving hydrogen inhalation experienced relief from pulmonary symptoms and longer progression-free survival compared to untreated patients.4
Progression-free survival refers to the length of time a patient lives without the cancer worsening. Researchers also observed that hydrogen therapy improved tolerance to chemotherapy, targeted therapy, and immunotherapy when used alongside conventional treatments.
• Hydrogen therapy improved quality of life during cancer treatments — Liver cancer patients undergoing radiation who drank hydrogen-rich water for six weeks reported meaningfully better quality of life — and importantly, the hydrogen didn’t weaken the radiation’s tumor-killing effects.5
The hydrogen therapy group showed reduced biological responses to radiation-induced oxidative stress without weakening the tumor-killing effects of radiation therapy. Researchers emphasized that hydrogen didn’t interfere with cancer treatment but instead reduced the damage to healthy tissue surrounding the tumors.
Hydrogen Therapy Improves Lung Inflammation and Brain Recovery
Hydrogen inhalation also demonstrated strong effects in respiratory disorders such as asthma and chronic obstructive pulmonary disease (COPD). In one clinical trial, patients inhaled a hydrogen-containing gas mixture for 45 minutes.6 Researchers observed significant reductions in inflammatory markers that signal inflammation in the lungs. Lower levels of these markers corresponded with reduced respiratory inflammation and improved breathing comfort.
• Neurological studies revealed hydrogen reaches the brain and improves recovery after injury — Because hydrogen molecules are extremely small and electrically neutral, they easily pass through biological membranes, including the blood-brain barrier that protects your brain from harmful substances.
Clinical trials investigating stroke and brain ischemia — meaning reduced blood flow to the brain — found that hydrogen inhalation or hydrogen-rich solutions reduced oxidative stress markers and improved neurological recovery scores in patients. Some patients also showed improvements in MRI imaging indicators that reflect reduced damage to brain tissue following stroke events.
• Hydrogen acts as a selective antioxidant — It neutralizes the most damaging reactive oxygen species, particularly hydroxyl radicals. These radicals are among the most destructive molecules produced inside cells because they attack DNA, proteins, and cellular membranes. By selectively neutralizing hydroxyl radicals while leaving beneficial signaling molecules intact, hydrogen preserves normal cellular communication while reducing oxidative damage.
• Hydrogen’s molecular size allows it to reach tissues other antioxidants can’t — Hydrogen has a molecular weight of only 2 Daltons, making it the smallest molecule in existence. Hydrogen is roughly 90 times smaller than vitamin C — small enough to slip through cell membranes the way air passes through a screen door.
Because of this extremely small size, hydrogen diffuses rapidly through biological membranes and distributes throughout the body, including inside mitochondria — the tiny structures that generate cellular energy. This rapid diffusion allows hydrogen to reach tissues that many drugs and antioxidants struggle to penetrate, including the brain and deep cellular compartments.
• Hydrogen therapy influences cellular signaling and inflammation regulation — Several clinical trials reported reductions in oxidative stress biomarkers and inflammatory cytokines after hydrogen therapy. Cytokines are small signaling proteins that coordinate immune responses. Think of cytokines as alarm signals your immune system sends — helpful in a crisis, but destructive when the alarm won’t stop ringing.
When cytokine levels become excessive, chronic inflammation develops and drives diseases such as heart disease, diabetes, and neurodegeneration. Hydrogen therapy helped bring these signaling molecules back to functional levels — enough to mount an immune response when needed, but not so much that inflammation becomes chronic and self-destructive.
Simple Ways to Use Molecular Hydrogen to Restore Cellular Balance
What makes these clinical findings so relevant is that hydrogen therapy isn’t locked behind a prescription pad or a hospital setting. Unlike many of the interventions studied in those trials — intravenous saline infusions, controlled gas inhalation under medical supervision — the core benefits of molecular hydrogen are accessible to you at home.
The same molecule that improved survival after cardiac arrest and reduced brain damage after stroke is available in forms you can use daily to protect your cells before disease takes hold. The question isn’t whether hydrogen works — the research increasingly confirms it does. The question is how to use it in a way that gives your body the greatest advantage.
Oxidative stress sits at the center of many chronic health problems. When damaging reactive oxygen species overwhelm your body’s defenses, mitochondria struggle to produce energy, inflammation rises, and recovery slows. Molecular hydrogen helps reset that system by supporting mitochondrial repair, improving cellular signaling, and reducing destructive oxidative stress.
When you combine hydrogen therapy with habits that protect your metabolism, you give your cells the conditions they need to recover and perform at their best. Here’s how to apply hydrogen therapy in a way that supports your body rather than working against it.
1. Start with hydrogen-rich water daily to restore cellular balance — If you want a simple place to begin, hydrogen-rich water offers one of the easiest entry points. Drop one hydrogen tablet into a glass of room-temperature water and drink it immediately after the tablet fully dissolves and the water turns cloudy. That cloudy appearance signals active hydrogen gas in the water.
Once the gas escapes, the therapeutic effect disappears. Drinking it right away ensures your body receives the hydrogen while it’s still active. If you deal with symptoms like brain fog, chronic fatigue, or persistent inflammation, taking hydrogen water two or three times daily — spaced at least an hour apart — creates a rhythmic pulse that strengthens your cellular defense systems.
2. Use the correct delivery method and timing — As noted in my interview with Tyler LeBaron, Ph.D., one of the world’s foremost experts on molecular hydrogen, hydrogen therapy works best when your cells receive it in short pulses rather than constant exposure. Hydrogen-rich water made from properly formulated tablets offers one of the most practical options for daily use. Drink it immediately after preparation so the hydrogen gas remains dissolved.
If you prefer inhalation, keep sessions short — about one to three hours — instead of continuous exposure. Intermittent exposure trains your cells to activate their own protective systems rather than becoming dependent on constant hydrogen supply.
3. Combine hydrogen therapy with habits that lower oxidative stress — Even the most powerful molecule can’t offset constant daily damage. If your goal is to restore cellular energy and reduce inflammation, the environment inside your body need to support that process.
Excessive intake of industrial seed oils, including soybean oil, corn oil, canola oil, or other vegetable oils, floods your cells with linoleic acid (LA), disrupting energy production and increasing oxidative stress. Replace seed oils with saturated fats such as grass fed butter, ghee, or tallow, and avoid ultraprocessed foods and restaurant meals, which are typically high in LA.
The goal is to get your LA intake below 5 grams, and ideally closer to 2 grams, daily. To track your intake, download the upcoming Mercola Health Coach app, which includes the Seed Oil Sleuth feature that calculates LA exposure with precise accuracy.
Alcohol also interferes directly with mitochondrial function and blocks recovery, so removing it from your routine protects the very systems hydrogen therapy strengthens. Daily sunlight exposure further amplifies the effect. Sunlight stimulates mitochondrial energy production and improves cellular signaling that hydrogen therapy supports.
If your body is full of LA from years of seed oil consumption, your skin is more prone to burning during midday sun. Avoid sunlight from 10 a.m. to 4 p.m. until you’ve reduced seed oils for at least six months, focusing instead on morning and late afternoon light. Once your tissues are free from these unstable fats, you’ll tolerate more sun safely.
4. Feed your metabolism with the carbohydrates your cells require — Starving your body with extreme dieting weakens mitochondrial energy production. When energy production drops, oxidative stress rises and your cells lose the ability to repair themselves. Your liver and muscles require adequate carbohydrates to maintain stable energy production.
Roughly 250 grams of carbohydrates per day supports metabolic function for most adults, with higher intake needed for people who exercise regularly. If your digestion struggles, begin with easy-to-digest foods like fruit and white rice before adding more complex carbohydrates. As your digestion improves, your body handles a wider range of foods and hydrogen therapy works more effectively.
5. Use hydrogen strategically before physical or mental stress — Timing hydrogen intake around stressful events strengthens your resilience. Drink hydrogen-rich water roughly 30 minutes before exercise, travel, intense workdays, or emotionally demanding situations. This pre-loads your cells with hydrogen right before the spike in oxidative stress that exercise, travel, or intense work normally triggers — giving your mitochondria a protective head start.
Many people notice sharper focus, better stamina, and faster recovery afterward. If you push hard physically or mentally, this timing strategy transforms hydrogen therapy from a passive supplement into a targeted tool that protects your cellular energy systems.
FAQs About Molecular Hydrogen Therapy
Q: What is molecular hydrogen therapy and why are scientists studying it?
A: Molecular hydrogen therapy uses hydrogen gas — the smallest molecule in existence — to help reduce oxidative stress inside the body. Oxidative stress occurs when reactive oxygen species build up and damage cells, contributing to diseases such as heart disease, cancer, neurological disorders, and metabolic dysfunction.
Research now includes more than 2,000 scientific papers and dozens of clinical trials investigating hydrogen therapy because it selectively neutralizes the most damaging free radicals without disrupting beneficial cellular signaling.
Q: What health conditions show the strongest evidence for hydrogen therapy?
A: Clinical studies reviewed in the journal Molecules report promising results across several major disease categories.7 These include cardiovascular diseases, cancer, respiratory illnesses such as asthma and COPD, neurological conditions including stroke and brain ischemia, metabolic disorders, autoimmune diseases, and chronic fatigue. Hydrogen therapy appears most effective in conditions driven by high oxidative stress and inflammation.
Q: How does molecular hydrogen work inside the body?
A: Hydrogen acts as a selective antioxidant that targets highly destructive molecules called hydroxyl radicals. These radicals damage DNA, proteins, and cellular membranes.
Because hydrogen has an extremely small molecular size, it easily diffuses through biological membranes and reaches tissues that many drugs can’t access, including your brain and mitochondria. This allows hydrogen to reduce oxidative stress, improve cellular signaling, and support mitochondrial energy production.
Q: What are the most common ways hydrogen therapy is used?
A: Hydrogen therapy is typically delivered in three ways: inhalation of hydrogen gas, drinking hydrogen-rich water, or receiving hydrogen-infused saline in clinical settings. Drinking hydrogen-rich water made with hydrogen-producing tablets is the simplest approach for daily use. In research studies, inhalation is also widely used, especially for respiratory and neurological conditions.
Q: How can you maximize the benefits of hydrogen therapy?
A: Hydrogen therapy works best when combined with lifestyle habits that lower oxidative stress. Limiting industrial seed oils that contain LA, avoiding alcohol, spending time in natural sunlight, and supporting mitochondrial energy production through adequate carbohydrate intake all help improve cellular health. Using hydrogen-rich water strategically — such as before physical or mental stress — also helps reduce oxidative stress and improve recovery.
Scientists confirm a shocking brain tumor risk hiding in your home

(NaturalHealth365) Most families never think twice about one of the most overlooked threats to brain health. For example, the mobile device on the kitchen counter, the “smart” meter attached to many homes, or the wireless router humming in the hallway. Unfortunately, these devices have become a normal part of life.
But a growing stack of peer-reviewed research is raising questions that are becoming very hard to ignore, and the answers affect every person in the household, not just the children.
A new peer-reviewed study published in Environmental Research followed 200 children diagnosed with central nervous system tumors and compared them to nearly 800 healthy children. The findings were sobering. Children exposed to elevated extremely low-frequency magnetic fields (ELF-MF) at levels above 0.4 microtesla faced more than double the risk of developing a brain tumor. Prolonged tablet use, even without internet access, was associated with a risk increase of up to 253%.
What the study found, and why it matters beyond childhood
Researchers measured ELF-MF radiation in children’s bedrooms for 24 hours to capture realistic daily exposure. The source of this radiation comes from power lines, household wiring, and common electrical equipment. More than 5% of the children in the study were already living with ELF-MF levels above 0.3 microtesla, exceeding levels reported in most other populations studied.
Children face heightened risk for clear biological reasons. Their central nervous systems are still developing, their brain tissue is more conductive than that of adults, and their smaller skulls allow radiation to penetrate into deeper brain regions. The International Agency for Research on Cancer has classified both ELF-MF and radiofrequency radiation as possibly carcinogenic to humans, a classification that applies regardless of age.
Adults are not off the hook. Someone who began living near high-voltage power lines in childhood and continues to do so decades later accumulates a lifetime of exposure that no single study can fully capture.
A 2025 systematic review commissioned by the World Health Organization found high-certainty evidence linking wireless radiation to malignant gliomas and nerve tumors in animal studies, tumor types that have also appeared in human research. The 2018 National Toxicology Program study, a $30 million, 10-year effort, found clear evidence of gliomas in rats exposed to cell phone radiation. Adults carrying devices in pockets, sleeping near routers, and working in high-EMF environments are running their own long-term experiment with unknown results.
The exposure nobody is talking about
By September 2021, 96% of U.S. public schools were providing tablets to students. Common Sense Media reported that 40% of children had a tablet by age 2. These devices are now embedded in daily life from toddlerhood through adulthood, yet the radiation they emit – even when not connected to the internet – was significantly associated with increased brain tumor risk in this study.
Western medicine has been largely silent on cumulative EMF exposure as a cancer risk factor, leaving families to navigate this threat without guidance.
Natural solutions to reduce your family’s EMF exposure
Lowering your radiation burden doesn’t require dramatic lifestyle changes, but it does require awareness and a few deliberate habits.
Create distance between your body and devices. Keep tablets and phones at arm’s length whenever possible. Distance dramatically reduces radiation exposure; even a few inches makes a measurable difference. Never place a tablet directly on a child’s lap for extended use, and avoid holding a phone against your head for long calls. Use speakerphone or a wired headset instead.
Reduce bedroom exposure where it counts most. The study measured radiation in children’s bedrooms because that’s where the body does its most critical repair work – during sleep. Remove tablets and phones from bedrooms at night. Turn off Wi-Fi routers before bed, and keep devices unplugged and away from sleeping areas. Adults benefit from these habits just as much as children.
Support your body’s cellular defense systems through nutrition. A strong immune system and efficient DNA repair mechanisms are your best internal defense against environmental carcinogens. Organic cruciferous vegetables, such as broccoli, cauliflower, and Brussels sprouts, activate detoxification enzymes through sulforaphane.
Selenium-rich foods like Brazil nuts support antioxidant pathways that help neutralize oxidative stress caused by radiation exposure. Astaxanthin, one of nature’s most potent antioxidants, has also shown promise in protecting against radiation-induced cellular damage.
Reduce your total toxic load. EMF exposure compounds with other environmental stressors, including pesticides, heavy metals, and inflammatory foods. Eat clean, prioritize filtered water, and support liver and lymphatic function through daily movement and targeted supplementation.
What cancer prevention experts want you to know
The connection between chronic environmental exposures and cancer risk is precisely what Western medicine underestimates, and what holistic health experts have been documenting for years. EMF exposure, oxidative stress, immune suppression, and toxic burden all feed the same underlying processes that allow abnormal cells to escape the body’s surveillance systems.

Is Fiber the New Protein? The Surprising Health Benefits of the Latest Wellness Trend

Analysis by Dr. Joseph Mercola March 04, 2026
Story at-a-glance
- Fiber has replaced protein as the latest wellness obsession, driven by social media trends, food industry marketing and growing concern over gut and metabolic health
- Most adults still consume far less fiber than recommended, a gap linked to digestive problems, unstable energy, blood sugar issues and higher chronic disease risk
- Fiber improves digestion, heart health, mood and brain function only when the gut environment is healthy, which explains why some people feel better while others feel worse when they increase intake
- Adding fiber too quickly or relying on fiber added to ultraprocessed foods often leads to bloating, gas and discomfort, especially in people with existing gut imbalance
- The safest way to benefit from fiber is to restore gut stability first, then increase fiber slowly using a wide variety of whole foods while avoiding dietary factors that damage gut and cellular health
You’ve probably seen the posts: influencers blending white beans into smoothies, food brands racing to add fiber to everything from protein bars to pasta, and headlines declaring fiber “the next protein.” But here’s what the trend pieces don’t mention — for a significant portion of people, suddenly increasing fiber intake makes them feel worse, not better. Understanding why reveals something important about how your gut actually works.
Despite that buzz, most adults fall far short of established intake targets. Surveys cited in mainstream reporting show average daily fiber intake well below governmental recommendations in both the U.K. and the U.S., creating a persistent nutritional gap.1,2
When fiber intake drops, consequences ripple outward: constipation and bloating become chronic, energy crashes mid-afternoon, blood sugar swings drive cravings, and inflammatory markers creep upward — a pattern researchers now link to increased risk of heart disease, Type 2 diabetes, and certain cancers.
This gap between enthusiasm and understanding creates a problem. On the one hand, growing interest reflects greater awareness of fiber’s connection to gut bacteria and broader health outcomes. On the other hand, the trend has outpaced clear guidance on how to integrate fiber into diets in a way that supports individual digestive health.
Here’s what most fiber advice misses: the same bowl of lentils that leaves one person feeling energized and satisfied can leave another bloated and exhausted for hours. These opposite reactions aren’t random — they reveal whether your gut is ready for fiber in the first place.
Why Fiber’s Health Momentum Comes with Caveats
A BBC report explains how fiber shifted from a background nutrient to a cultural fixation.3 It draws on interviews with dietitians, researchers and consumers to show why fiber now gets framed as a marker of overall health rather than something linked only to bowel habits.
Still, the average fiber intake in the U.K. sits around 16.4 grams per day, far below the National Health Service’s recommendation of 30 grams, with about 96% of adults failing to reach that benchmark. Kevin Whelan, professor of dietetics at King’s College London, explains that populations with higher fiber intake show lower rates of cardiovascular disease, diabetes and some cancers. This frames fiber less as a trend and more as a long-standing nutritional gap.
• Different fiber types act through different biological pathways — Whelan explains that fermentable fibers support beneficial gut bacteria, insoluble fibers help move waste through your digestive tract and viscous fibers slow sugar absorption, which reduces blood sugar spikes.
Fermentable fibers are like slow-burning fuel for your gut bacteria — they break them down through fermentation (similar to how yeast ferments sugar into alcohol) and produce beneficial compounds called short-chain fatty acids in the process. Insoluble fibers, by contrast, pass through largely intact, adding bulk that keeps waste moving.
Put simply, fiber does several jobs at once rather than working through a single mechanism. This helps explain why fiber affects energy levels, appetite control and digestion at the same time. The BBC includes stories from individuals who reduced ultraprocessed foods and increased fiber-rich meals, reporting improvements in energy, skin health and emotional balance
• Higher fiber intake linked with improvements in mood and anxiety, an effect tied to the gut-brain axis — This term describes the two-way communication between your gut and your brain through nerves, hormones, and immune signaling. Think of it as a biochemical phone line between your gut and brain. Whelan notes that prebiotic fibers support gut bacteria that send calming signals to your brain, helping explain reductions in anxiety and low mood.
• Cognitive benefits appear especially relevant for older adults — One finding highlighted in the article shows improved cognitive performance in people over age 60 who consumed more fiber.4 This is a downstream effect of better gut health, reduced inflammation and improved metabolic stability.
• Clear warnings appear against increasing fiber too fast — Rapid increases in fiber often lead to bloating, gas, and constipation, particularly in people accustomed to low-fiber diets. Cara Wheatley-McGrain explains that gut bacteria need time to adapt to higher fiber intake.
This underscores the importance of pacing rather than treating fiber intake like a competition. Fiber absorbs water, so inadequate fluid intake worsens discomfort. Conditions such as Crohn’s disease and diverticulitis also require extra caution with fiber increases.
• The article questions single-nutrient thinking — The BBC emphasizes that enthusiasm around fiber only helps when it leads to better overall eating patterns, not when it encourages fortified ultraprocessed foods. The reporting pushes back on the idea of treating fiber as a standalone fix and raises the question of whether trends improve health or simply recycle old habits under a new label.
Fiber Replaces Protein as the Functional Food Centerpiece
If the science supports fiber, industry has noticed. Consumer priorities have shifted from muscle-building toward gut health, and food companies are racing to capitalize, according to a report by The Food Institute.5 Fiber emerged as the next growth driver because it aligns with digestion, blood sugar control, inflammation, and cardiovascular health all at once.
Many adults consume only about half of recommended fiber intake, a deficiency linked to digestive irregularity, glucose instability, chronic inflammation, and heart disease risk. That gap made fiber an easy target for reformulation and marketing across food and beverage categories.
• When PepsiCo’s CEO publicly declares that “fiber will be the next protein,” it signals more than a nutrition trend — It signals a marketing gold rush. And that should give health-conscious consumers pause. As reported by the Associated Press, PepsiCo CEO Ramon Laguarta said, “I think fiber will be the next protein … Consumers are starting to understand that fiber is the benefit that they need.”6
• Specific fiber ingredients gain traction because they show measurable effects — The Food Institute points to inulin, beta-glucans, galacto-oligosaccharides, and resistant starch as fibers linked to improved microbial diversity, insulin response, digestion, and heart health. These outcomes give fiber a stronger scientific footing than many functional ingredients.
• Experts raise concerns about fiber added to processed diets — Sander Kersten, director of the Division of Nutritional Sciences at Cornell University, cautions that long-term benefits come from studies of whole foods, not processed products fortified with isolated fiber.7 He notes that consuming fiber additives alongside a Western diet low in whole plants may not produce the same outcomes.
Kersten emphasizes that people eat foods, not isolated nutrients, and that focusing on one ingredient risks repeating the same mistakes seen during the protein boom. Fiber enthusiasm helps only when it improves overall dietary patterns rather than just adding functional claims to ultraprocessed foods.
Many high-fiber processed foods also contain ingredients such as soy, shellfish derivatives or psyllium husk, which trigger reactions in sensitive individuals. This highlights a practical risk: increasing fiber through packaged foods increases exposure to hidden allergens that don’t exist in whole fruits or vegetables.
• GLP-1 weight-loss drugs quietly drive fiber demand — The Associated Press notes that drugs such as Ozempic and Wegovy slow digestion and commonly cause constipation, increasing demand for fiber products marketed to manage side effects.8 This connection explains why fiber interest accelerated alongside GLP-1 use. It also reframes fiber growth as partly pharmaceutical-driven rather than purely nutrition-driven.
GLP-1 drugs work by slowing gastric emptying — food stays in your stomach longer, which reduces appetite but also slows the entire digestive transit. The result is often constipation, sometimes severe. Fiber helps by adding bulk and drawing water into your colon, but users should be aware that the same slowed motility often makes fiber-induced bloating worse initially.

How to Increase Fiber Without Wrecking Your Gut
Understanding why fiber matters is one thing. Knowing how to increase it without triggering the very symptoms you’re trying to resolve is another — and this is where most fiber advice falls short. Fiber helps only when your gut environment is ready for it. When it’s not, fiber intensifies symptoms instead of resolving them.
This disconnect — known as the fiber paradox — explains why some people feel better with more fiber while others experience bloating, pressure and fatigue. The real issue sits at the level of gut integrity and bacterial balance, not willpower or food quality.
Your gut lining is protected by a mucus layer roughly the thickness of a credit card. This barrier isn’t just passive padding — it’s a dynamic feeding station where beneficial bacteria graze on complex sugars while staying safely separated from your intestinal cells. When fiber runs low, these bacteria don’t simply go dormant; they get hungry and start eating the mucus itself.
As this protective layer thins, the physical distance between gut bacteria and your immune cells shrinks, making inflammatory reactions far more likely. Adding large amounts of fiber at this stage worsens the situation rather than repairing it. Here’s how to resolve the fiber paradox safely and rebuild gut health step by step.
1. Delay fiber increases until gut stability returns — Ongoing bloating, erratic stools, food reactions or post-meal fatigue signal a compromised gut barrier. In that state, fermentable fiber fuels pathogenic bacteria that release lipopolysaccharide, or LPS, when they break down. LPS is a powerful endotoxin that drives systemic inflammation once it crosses a weakened gut lining.
Think of LPS as a chemical alarm signal embedded in the cell walls of certain bacteria. When these bacteria die and break apart in your gut, LPS fragments are released. In a healthy gut, your intestinal lining acts like a tight security gate, keeping LPS contained.
But when that barrier weakens, LPS slips into your bloodstream, where your immune system treats it as an invader — triggering inflammation that affects everything from your joints to your brain. Holding fiber steady at a lower level reduces that inflammatory load and allows healing to begin.
2. Prioritize digestive calm before dietary complexity — A calmer gut environment develops through consistent meals, simpler food combinations and reduced exposure to known irritants. As inflammation settles, bowel habits normalize and bacterial behavior becomes less aggressive. This creates the internal conditions required for fiber to act as support rather than stress.
3. Build carbohydrate intake on gentler foundations first — Most adults function best with roughly 250 grams of carbohydrates per day, which support both energy production and gut repair. Easily digested sources such as white rice and whole fruits provide glucose without overwhelming a sensitive microbiome.
This phase rebuilds your metabolic foundation — stabilizing blood sugar, calming inflammation, and giving your gut lining time to repair — before asking your system to handle the fermentation workload that comes with higher fiber.
4. Increase fiber gradually as tolerance improves — Improved digestive comfort, reduced bloating and more regular stools mark the point where it’s safe to expand your fiber intake. Root vegetables typically come first, followed by non-starchy vegetables, then starchy vegetables like squash or sweet potatoes. Beans, legumes and minimally processed whole grains follow later.
Resistant starches, like cooked-and-cooled white potatoes or green bananas, are also helpful. These feed butyrate-producing bacteria — the kind that protect your gut lining and regulate inflammation. Butyrate is the preferred fuel source for the cells lining your colon.
When these cells are well-fed, they maintain tight junctions that prevent unwanted substances from leaking into your bloodstream. Butyrate also signals your immune system to stay calm rather than reactive. Diversity matters more than speed, since different plants supply different fibers that rebuild microbial balance.
5. Remove dietary factors that undermine gut repair — Excess linoleic acid (LA) from seed oils disrupts mitochondrial energy production and weakens your gut barrier at a cellular level. Replacing these oils with grass fed butter, ghee or tallow supports cellular resilience, which improves fiber tolerance over time.
This might seem unrelated to fiber, but mitochondrial health directly determines how well your gut cells maintain their protective barrier and how efficiently they process the increased metabolic demands of fiber fermentation. Seed oils high in LA — including soybean, corn, canola, and sunflower oils — accumulate in cell membranes over time, impairing mitochondrial energy production. This creates a cellular environment where fiber is more likely to cause problems.
When energy production stabilizes, your gut environment becomes far more adaptable. When gut repair leads the process, fiber stops acting like a trigger. It becomes fuel for beneficial microbes, strengthens your gut barrier and supports long-term health without the backlash that derails so many people.
FAQs About Fiber as the New Protein
Q: What does it mean when people say fiber is “the new protein”?
A: Fiber has taken on a similar role to protein in food marketing and wellness culture, with brands and influencers promoting it as a foundational nutrient for long-term health. Unlike protein, which most adults already consume in adequate amounts, fiber fills a widespread intake gap and connects to digestion, metabolic health, inflammation control and cardiovascular risk.
Q: Why do some people feel better with more fiber while others feel worse?
A: It depends on what’s already happening in your gut. If your gut lining is intact and your bacterial populations are balanced, fiber acts like premium fuel — feeding beneficial species that protect your health. But if your gut is already inflamed or overrun with opportunistic bacteria, fiber feeds the wrong populations first, producing gas, toxins, and inflammation. Same food, opposite outcomes. This contrast is known as the fiber paradox.
Q: Is all fiber equally beneficial, regardless of the source?
A: No. Most long-term benefits come from fiber consumed in whole foods, not from isolated fibers added to ultraprocessed products. Fiber behaves differently depending on the food matrix, and additive fiber in processed diets does not guarantee the same health outcomes.
Q: Why is fiber intake linked to mood and brain health?
A: Higher fiber intake supports gut bacteria that communicate with your brain through the gut-brain axis, a two-way signaling system involving nerves, hormones, and immune pathways. Studies cited in the article link higher fiber intake to improvements in mood, anxiety and cognitive performance, particularly in older adults.
Q: What’s the safest way to increase fiber without digestive problems?
A: Fiber works best when introduced gradually and only after gut stability improves. Starting with gentler carbohydrate sources, expanding fiber variety slowly and avoiding factors that damage gut health — such as excessive seed oil intake — allows fiber to support healing instead of triggering inflammation.
This Small Molecule Reverses Alzheimer’s Disease Progression, Study Shows
Reproduced from original article:

Analysis by Dr. Joseph Mercola February 17, 2026
Story at-a-glance
- Nicotinamide adenine dinucleotide (NAD+) is central to cellular energy and mitochondrial health, driving redox reactions that produce ATP. Declining levels are linked to metabolic disorders, sarcopenia, and diabetes
- Alzheimer’s disease has strongly associated with disrupted NAD+ balance, and research suggests restoring intake can reverse cognitive decline rather than merely slowing disease progression
- Animal studies show restoring NAD+ fully reversed advanced Alzheimer’s features, including memory loss, inflammation, tau pathology, oxidative stress, and DNA damage, even after severe disease was established
- NAD+ functions as an upstream regulator of brain resilience, coordinating energy production, DNA repair, inflammation control, and protein processing, reframing Alzheimer’s as a systems-level energy failure
- Practical strategies emphasize testing NAD+ status and supporting production safely via niacinamide alongside adequate intake of other B vitamins
Nicotinamide adenine dinucleotide (NAD+) may be one of the most overlooked factors when it comes to optimizing cellular health. It is a cellular coenzyme that plays a role in many metabolic and signaling reactions.
For example, it partakes in redox reactions — chemical exchanges that transfer energy between molecules — which lead to the production of adenosine triphosphate (ATP), your body’s energy currency.1 In fact, research shows that a deficiency is linked to an array of conditions, such as sarcopenia and diabetes.2
But that’s not all — Alzheimer’s disease, the most common form of dementia,3 has now been linked to declining NAD+ levels. Following this line of thought, emerging research shows that boosting NAD+ intake can reverse the progression of Alzheimer’s disease. This discovery could be one of the biggest breakthroughs in recent times, as most people believe that Alzheimer’s only worsens the longer it goes,4 and treatment focuses on slowing decline rather than reversing it.
Restoring Brain Energy Reversed Advanced Alzheimer’s in Animal Models
A study published in Cell Reports Medicine set out to discover how Alzheimer’s disease can be reversed by boosting NAD+ levels. For the experiment, the researchers used multiple mouse models of Alzheimer’s disease that already showed severe cognitive impairment, brain inflammation, tau pathology, and structural brain damage.5
Mice were administered P7C3-A20 at a dosage of 10 milligrams (mg) per kilogram (kg) of weight each day. Analysis involved observing changes across behavior, brain chemistry, and physical brain structure. For context, P7C3-A20 is a carbazole compound that can readily cross the blood-brain barrier. It works by binding to NAMPT (an enzyme that controls how much NAD+ is made from niacinamide) to enhance NAD+ production6 at safe levels.
• One striking finding is the rate of improvement — The authors reported that in treated mice, cognitive function recovered fully, meaning their memory performance returned to levels seen in healthy animals. These mice performed just as well as non-diseased controls on learning and memory tests.
• What changed inside the brain samples — Multiple hallmarks of Alzheimer’s disease improved at the same time. Tau pathology, which refers to tangled protein structures that disrupt neuron function, decreased after NAD+ restoration. Neuroinflammation markers dropped, indicating a calmer immune environment in the brain. Signals of oxidative stress and DNA damage — both signs of energy failure inside cells — also declined.
• Results were observed right away — The intervention occurred after the disease had fully developed in these animals. Again, this directly challenges the long-standing belief that Alzheimer’s damage becomes permanent once it crosses a certain threshold.
• Other disease models were used to solidify the findings — The researchers tested the same approach in two different forms of Alzheimer’s pathology. In amyloid-driven mice and in tau-driven PS19 mice, restoring NAD+ reversed advanced disease features. That distinction matters because amyloid and tau represent different biological drivers of Alzheimer’s. Seeing improvement in both strengthens the argument that NAD+ disruption sits upstream of these visible brain lesions.
• Blood biomarkers also benefited — Treated animals showed reduced levels of phosphorylated tau 217, a biomarker now used clinically to track Alzheimer’s severity. This helps bridge the gap between animal research and its implications for Alzheimer’s disease in humans.
• At the center of all the changes is NAD+ homeostasis — NAD+ is required for cells to convert nutrients into usable energy and to repair daily damage to proteins and DNA. That said, the study found that Alzheimer’s disease severity correlated with how disrupted NAD+ balance became in the brain. In other words, as energy systems failed, disease features worsened and restoring that balance reversed the cascade.
The researchers described this as a “resilience” model rather than a single-target approach. Instead of attacking amyloid alone or tau alone, restoring NAD+ stabilized multiple systems at once — energy production, inflammation control, blood-brain barrier integrity, and cellular repair. Thus, the findings reframe Alzheimer’s as a system-level energy failure rather than a mystery buildup of toxic debris in the brain.
• Human relevance strengthened the findings further — Using human brain samples and sophisticated molecular analysis techniques, the authors reported that NAD+ disruption also tracked with Alzheimer’s severity in people. They identified overlapping biological nodes between mice and humans that responded to restored NAD+ balance.
• Mechanistic explanation of the benefits — The paper explained that NAD+ acts as a central coordinator for enzymes involved in DNA repair, mitochondrial function, and stress resistance. When NAD+ levels fall, these systems stall. Neurons, which require constant energy, suffer first. Restoring NAD+ reactivated these pathways simultaneously.
The study also highlighted why focusing solely on plaques has delivered limited success. Amyloid and tau accumulation appeared downstream of NAD+ disruption rather than as isolated causes. Once energy systems failed, the brain lost its ability to manage protein turnover, immune balance, and structural integrity. Fixing the upstream energy deficit corrected multiple downstream failures at once.
From a practical standpoint, the findings support the idea that improving cellular energy changes the trajectory of Alzheimer’s disease rather than simply slowing damage. It shows that neurons under metabolic stress can recover when you address cellular energy production at its root.
NAD+ Restores Memory by Rewriting Neuronal Instructions
In a related study published in Science Advances, researchers examined how restoring NAD+ reverses Alzheimer’s features inside brain cells from a genetic perspective. Specifically, the researchers focused on gene regulation, which influences how neurons read and process instructions that control memory and brain resilience.7
• Core findings of the analysis — Increasing NAD+ corrected widespread errors in gene instruction processing and restored memory performance, but only when a specific control protein, EVA1C, remained intact. When this was suppressed, the memory benefit disappeared, even with NAD+ restoration.
Another important improvement that was observed is memory retention. Animals receiving NAD+ showed clear restoration of learning and recall ability, measured through standardized behavioral tests used in neuroscience research. When researchers interfered with EVA1C expression in the hippocampus, those gains vanished, even though NAD+ levels rose.
• A deeper look into the mechanism at play — The study showed that NAD+ corrected abnormal alternative splicing events across many genes. For context, alternative splicing refers to how cells assemble genetic instructions before building proteins.
Think of the process as editing a recipe. If the editing goes wrong, the cell produces dysfunctional proteins. In Alzheimer’s models, these editing errors appeared widespread. NAD+ restored normal editing patterns, but only through EVA1C.
• The largest benefits appeared in hippocampal neurons — This is especially observed within the CA1 region. For context, the hippocampus is the brain’s memory hub, and CA1 neurons act as a relay station for forming and retrieving memories. When EVA1C levels dropped in this region, NAD+ no longer improved memory performance.
• Comparisons between test variables — NAD+ alone improved memory only when EVA1C function remained intact. Meanwhile, EVA1C suppression alone worsened memory outcomes even when energy levels improved. This shows that NAD+ and EVA1C did not work independently — they functioned as a linked system, with EVA1C acting as the gatekeeper for the cognitive benefits of NAD+.
The study also included human data. Researchers reported that EVA1C expression was reduced in the hippocampus of participants with Alzheimer’s disease compared to cognitively normal controls.
• A closer analysis of the mechanisms involved — Ribonucleic acid (RNA) splicing determines which protein versions neurons produce. In Alzheimer’s disease, incorrect splicing led to dysfunctional proteins that weaken synapses and disrupt communication between brain cells. Now, NAD+ restored normal splicing patterns by regulating EVA1C activity, which stabilized protein production inside neurons.
Again, the researchers emphasized that this process represented a form of resilience. Neurons did not simply slow deterioration — they regained the ability to produce functional proteins required for learning and memory.

Before Boosting Levels, It’s Important to Get a Baseline
Based on the findings, boosting NAD+ has enormous potential when it comes to managing Alzheimer’s disease. Hence, testing your current levels is important, as it would be wise not to take any supplement without proper direction or planning.
• A new test will be launched in the future — I’m excited to introduce the upcoming Mitochondrial Wellness Test Kit, which is designed to offer you a current snapshot of your mitochondrial function. While this provides an overview, additional targeted testing may still be needed to fully understand the more intricate nuances of your health.
• Existing NAD+ tests fall short — NAD+ is highly unstable once it’s outside the cells and degrades quickly, making reliable measurement difficult. To maintain accuracy, it requires immediate processing and advanced laboratory methods.
In practice, this means blood samples need to be collected and analyzed rapidly within the same research facility, which is not possible at most clinics. Moreover, transporting samples between labs further compromises integrity. Despite these obstacles, my team and I have remained committed to advancing practical health testing for everyone.
• A higher standard for NAD+ assessment — Mercola Labs is developing a novel solution that avoids the pitfalls of measuring NAD+. Instead, we assess NAD+ levels by analyzing redox balance among these essential biomarkers — acetoacetate and beta-hydroxybutyrate, lactate and pyruvate, and the oxidized and reduced forms of glutathione. Additional details will be shared closer to release.
Niacinamide Supports NAD+ Production
Taking niacinamide is a convenient way of boosting your NAD+ levels. However, this approach calls for precision and balance — the reason why I encourage proper testing. While high doses have shown benefits in clinical settings, smaller and consistent amounts are far more appropriate for everyday use. This approach supports mitochondrial and metabolic function without placing unnecessary stress on the body, since excessive intake can disrupt methylation pathways and raise the risk of adverse events over time.
• Take small, evenly distributed daily doses — For daily support, take 50 milligrams of niacinamide three times per day. This modest dose supports NAD+ production without the risks associated with high-dose vitamin B3 supplementation. You can even divide it into four servings per day. Take one dose upon waking, one before bed, and space the remaining doses evenly throughout the day.
• Excessive B3 intake can be counterproductive — Taking too much vitamin B3, whether as niacin or niacinamide, will lead to negative outcomes. Research cited by the Cleveland Clinic indicates that high doses can increase cardiovascular risk.8 Although both compounds are forms of vitamin B3, niacin does not activate NAMPT the way niacinamide does, making niacinamide the preferred option.
• Don’t forget the other B vitamins — Adequate intake of other B vitamins is essential for overall health and mitochondrial function, particularly niacin, riboflavin, and folate. Suboptimal mitochondrial health is often linked to B-vitamin deficiencies,9 which can typically be corrected with a low-dose, high-quality B-complex supplement.
When it comes to food sources, vitamin B3 is abundant in grass fed beef and mushrooms.10 Vitamin B6 is found in grass fed beef, potatoes, and bananas.11 Folate (vitamin B9) is plentiful in spinach, broccoli, and asparagus,12 while vitamin B12 is concentrated in foods such as grass fed beef liver, wild rainbow trout, and wild sockeye salmon.
Frequently Asked Questions (FAQs) About NAD+ and Its Link to Alzheimer’s Disease
Q: What is NAD+ and why is it essential for cellular and brain health?
A: NAD+ is a core cellular coenzyme required for energy production, mitochondrial function, DNA repair, and metabolic signaling. Low NAD+ levels impair cellular energy and are linked to aging, metabolic disease, and neurodegeneration.
Q: How is NAD+ connected to Alzheimer’s disease progression?
A: Research shows Alzheimer’s disease severity correlates with disrupted NAD+ balance. Declining NAD+ levels impairs neuronal energy, repair, and resilience, suggesting the condition is driven by upstream energy failure rather than plaque buildup alone.
Q: Can restoring NAD+ reverse Alzheimer’s-related damage?
A: In advanced animal models, restoring NAD+ led to full cognitive recovery, reduced inflammation, improved tau pathology, and lower blood biomarkers, even after severe disease was established, challenging the idea of irreversible damage.
Q: How does NAD+ improve memory at a genetic and cellular level?
A: NAD+ restores proper gene instruction processing through EVA1C-dependent RNA splicing, particularly in hippocampal neurons. This allows neurons to rebuild functional proteins required for learning and memory, promoting true neuronal recovery.
Q: What is the safest way to support NAD+ levels?
A: Modest, consistent niacinamide dosing, combined with adequate B vitamins, supports NAD+ production safely without disrupting methylation or increasing health risks.

- Music activates multiple brain regions at once, including those tied to memory, movement, and emotion, making it especially useful for supporting recovery and preserving connections in dementia care
- Enjoying music at an appropriate volume encourages regular listening, helping you incorporate joyful routines into your daily life
- Joining a choir or playing an instrument also builds focus, coordination, and social connection. These factors may help keep your brain strong as you age
In the U.S., approximately 7.2 million adults aged 65 and older are living with Alzheimer’s disease, the most common form of dementia.1 That number is expected to rise to nearly 14 million by 20602 if no breakthroughs emerge. Each new diagnosis means another family navigating memory loss, personality shifts, and the emotional and financial demands of caregiving.
Healthcare costs are enormous and are expected to reach $384 billion in 2025, with unpaid family care valued at over $400 billion.3 With no cure in sight, researchers are turning to lifestyle strategies that may help delay symptoms and protect brain health. One of the areas they’re recently focusing on is music.
How Does Playing an Instrument Influence Dementia Risk in Older Adults?
The connection between music and brain health is gaining scientific attention, and new evidence suggests it may be more powerful than previously thought. A study published in the International Journal of Geriatric Psychiatry,4 led by researchers at Monash University in Australia, explored whether listening to music or playing an instrument could help protect against dementia and cognitive decline in people aged 70 and older.
• Researchers studied 10,893 Australians age 70 and older — The researchers examined data from participants enrolled in the ASPREE (ASPirin in Reducing Events in the Elderly) study and the ALSOP (ASPREE Longitudinal Study of Older Persons) sub-study. These large Australian cohorts followed older adults over time to track health outcomes. The participants were dementia-free at enrollment.
The team collected information on the subjects’ music-related habits, particularly how often they listened to music or played an instrument, and tracked cognitive health for several years. The goal was to see if these habits predicted dementia, cognitive impairment no dementia (CIND), and changes in thinking skills over time.5
• Frequent music listening showed the strongest protection — Participants who always listened to music had a 39% lower risk of developing dementia and a 17% lower risk of CIND compared to those who rarely or sometimes listened.6 They also maintained higher scores in global cognition and memory, which are key for everyday tasks such as recalling events and making decisions. Other cognitive domains, such as attention and language, did not show improvement.
• Playing an instrument offered benefits — Older adults who often or always played an instrument had a 35% lower risk of dementia.7 However, this activity was not linked to reduced CIND risk or improvements in cognitive test scores over time. Researchers suggest that while playing music may help, listening appears to have a more consistent effect on brain health.8
• Combining listening and playing gave additive benefits — Those who engaged in both listening and playing music had a 33% lower risk of dementia and a 22% lower risk of CIND.9 Lead author Emma Jaffa, an honors student in the School of Public Health and Preventive Medicine at Monash University, explained:
“These findings suggest music activities may be an accessible strategy for maintaining cognitive health in older adults, though causation cannot be established.”10
• Education level influenced the impact of music — The protective effects of music were most potent in participants with 16 or more years of education, while results were mixed for those with 12 to 15 years.11 Researchers believe this may relate to cognitive reserves, the brain’s ability to compensate for aging, where higher education combined with music engagement offers greater protection.
• No improvement in perceived mental sharpness — Despite objective gains in memory and global cognition, participants did not report feeling mentally sharper. This highlights a gap between clinical measures and personal perception, suggesting that lifestyle habits can improve brain health even if people don’t notice the changes.12
“Evidence suggests that brain aging is not just based on age and genetics but can be influenced by one’s own environmental and lifestyle choices,” senior author Professor Joanne Ryan, head of the Healthy Ageing Research Program at Monash University, said. “Our study suggests that lifestyle-based interventions, such as listening and/or playing music, can promote cognitive health.”13
Here’s a quick overview of the study findings, showing how everyday music habits were linked to memory and dementia risk in older adults:
| Music habit | Risk reduction (%) | What this means |
|---|---|---|
| Listening to music most days | 39% lower risk of dementia, 17% lower risk of CIND | Regular listening lowered dementia risk and slowed cognitive decline |
| Playing a musical instrument often | 35% lower risk of dementia | Playing an instrument may support brain health, but the benefits were limited |
| Listening to music and playing an instrument | 33% lower risk of dementia, 22% lower risk of CIND | Combining both activities showed strong protection |
Dementia Isn’t Just ‘Getting Older’
According to the Alzheimer’s Association, dementia is “a general term for loss of memory, language, problem-solving, and other thinking abilities that are severe enough to interfere with daily life.”14 It’s sometimes called “senility,” a term based on the outdated belief that serious mental decline is a regular part of aging. But in reality, dementia reflects disease-related changes in the brain, not aging itself.15
Although they’re often confused for each other, dementia is not the same as Alzheimer’s disease. Rather, dementia is the umbrella term for conditions that cause cognitive decline, and Alzheimer’s is the most common type.
• Alzheimer’s accounts for about 60% to 80% of dementia cases — The next most common cause is vascular dementia, which develops when blood flow to the brain is reduced due to damaged or blocked blood vessels.
Some people experience changes linked to more than one type of dementia at the same time, known as mixed dementia. Other health issues can cause memory and thinking problems that look like dementia but aren’t permanent, including thyroid disorders and vitamin deficiencies.16
• What happens in the brain when you have dementia — Dementia begins when nerve cells in the brain (neurons) and their connections start breaking down. In Alzheimer’s disease, this process is driven by the buildup of sticky protein deposits called plaques, as well as twisted fibers called tangles, which disrupt communication between neurons.17
Over time, these changes shrink brain tissue and damage areas responsible for memory, reasoning, and language. These changes occur gradually, often taking years before symptoms appear.
• Dementia progresses in stages — In the early stage, people can still manage most daily tasks but may need reminders for appointments. The confusion becomes worse during the middle stage, and managing finances or cooking becomes difficult; help with dressing or bathing may be needed as well. During the late stage, independence is diminished as individuals frequently need full-time assistance with eating, using the bathroom, and moving around.18
• Risk factors you should know — Age is the most substantial risk factor, with most cases developing after the age of 65. Family history also plays a role, especially if a parent or sibling has dementia. Heart health matters too, as high blood pressure, diabetes, and smoking damage blood vessels and increase risk. Lifestyle factors such as physical inactivity, poor diet, and social isolation further raise vulnerability.19

Why Music Works as a Therapeutic Tool
When you listen to music, your brain lights up in several areas at once,20 including the auditory cortex that processes sounds, the limbic system that handles emotions, and the motor cortex, which is involved with movement. This “whole-brain” activation is powerful because most therapies only stimulate one or two regions. This is why music is gaining ground in hospitals and clinics, where it’s used as a tool to not just help patients pass the time but also support healing.21
• People with brain conditions often benefit the most — In people with brain injuries or neurodegenerative diseases, music stimulates key brain regions tied to memory, emotion, movement, and speech. One powerful example comes from patients recovering from a stroke. Those who struggle to speak may be able to regain words by singing. Using melody and rhythm also helps retrain the brain’s speech pathways22 when regular speech therapy isn’t enough.
• Music quickly calms the body — Slow, steady music can help your body relax by syncing with its natural rhythms. This gentle pace signals your parasympathetic nervous system, the part responsible for the “rest and digest” state. When that kicks in, your heart rate slows, blood pressure drops, and tense muscles start to loosen.23
• Music may protect the brain in multiple ways — A study published in Aging & Mental Health found that musicians were 64% less likely to develop mild cognitive impairment or dementia.24 Another study published in BMC Neurology suggests this protection may come from several overlapping effects, including improved executive function and working memory, enhanced brain plasticity, sensorimotor repair, reduced stress and depression, and increased social engagement.25
• Music’s benefits are evident in people already living with dementia — A study published in International Psychogeriatrics found that 39 residents in long-term care facilities in Iowa who listened to individualized music playlists experienced a significant reduction in agitation, including shouting and irritability, both during and after listening sessions. These benefits were more pronounced compared to when residents listened to generic classical relaxation music.26
• The link between music and the prefrontal cortex — Located behind the forehead, the medial prefrontal cortex is one of the last brain regions to deteriorate in Alzheimer’s disease, and it is strongly activated by music. Petr Janata, Ph.D., from the UC Davis Center for Mind and Brain, mapped brain activity while people listened to familiar music and explained:27
“What seems to happen is that a piece of familiar music serves as a soundtrack for a mental movie that starts playing in our head. It calls back memories of a particular person or place, and you might all of a sudden see that person’s face in your mind’s eye. Now we can see the association between those two things — the music and the memories.”
• Music deserves a place in healthy aging strategies — Researchers from the University of Exeter believe music should be included in strategies to support healthy aging and reduce dementia risk. They recommend encouraging adults to sing, take part in community music groups, or return to instruments they played earlier in life.28
“Public health interventions to promote healthy aging and dementia risk reduction should consider including advice for adults on engaging with music … There is considerable evidence for the benefit of music group activities for individuals with dementia, and this approach could be extended as part of a healthy aging package to proactively reduce risk and promote brain health,” they concluded.

How to Start Building a Dementia-Friendly Music Routine
Making music part of the daily routine doesn’t have to be complicated. Whether you’re caring for someone with dementia or creating your own brain-supportive habits, these steps will help you build a simple, personalized music routine that fits into daily life and supports long-term well-being:
• Make time for music every day — This can be listening to your playlist, singing along, or playing a simple instrument. Start small and build up gradually. The goal is to make music a regular, enjoyable part of your routine so it feels familiar and comforting.29
• Build a personalized playlist of favorite songs — Start picking out favorite songs you would hum and dance to. Familiar music helps spark memories, reduce anxiety, and improve mood for people with dementia. These tunes create comfort and connection, making sessions more enjoyable and effective.30
• Keep the environment calm — Pick a quiet room with minimal distractions. Use a comfortable chair and the listening method that feels best, whether it’s speakers or headphones. A quiet setting lowers stress and helps you focus on the music.31
• Be considerate of the loudness — Keep the volume comfortable and avoid sudden changes in tempo or loudness. Pausing between songs can help prevent overstimulation, while gentle pacing ensures the experience remains soothing for you.32
• Get active, then get social — When listening becomes comfortable, start with simple activities such as tapping a beat, humming, or singing along. Participating in a local singing group can also foster social connections.
• Review weekly and make changes — At the end of each week, look at what worked best. Which songs felt good? Was the session too long or too short? Was the room comfortable? Keep the things that helped and remove anything that caused stress. This makes your routine easier to follow and more enjoyable.

4 Ways to Bring More Music into Your Life
If you already listen to music regularly, you can make it an even bigger and more meaningful part of your daily routine with these four tips:
1. Play an instrument — If you’ve ever wanted to learn an instrument, this is a great time to begin. Don’t worry about getting it right on the first try. Start with a few chords, a simple rhythm, or a beginner keyboard app. Even simple strumming on a guitar or tapping a drum gives your brain a workout while offering a sense of accomplishment and joy.
2. Use music to connect — Join a choir, attend a drum circle, or simply sing with friends or family. Shared music sparks bonding hormones like oxytocin, easing feelings of isolation and boosting emotional resilience. Plus, it’s fun — and fun is healing. These moments of connection can be especially meaningful for caregivers and loved ones navigating cognitive changes together.
3. Practice mindful listening — Instead of letting music fade into the background, choose one song and give it your full attention. Close your eyes, breathe deeply, and let the sound wash over you. This focused listening activates brain circuits that reduce stress, restore balance, and help you feel more centered and calmer — a simple ritual that can transform your day.
4. Reset your rhythm when life feels off track — If your sleep or energy feels out of sync, try listening to steady, rhythmic music at the same time each day, such as right after waking or before bed. Rhythm helps your brain re-establish patterns, regulate your internal clock, and create a sense of predictability that feels comforting and grounding. Think of it as a gentle reset button for your mind and body.
Music isn’t about hitting every note perfectly or remembering every lyric. It can also be about laughing when you miss a beat, sharing a song with someone else, and finding comfort in familiar melodies that bring you back to yourself. These moments nourish your brain, lift your spirit, and strengthen bonds that no diagnosis can erase.

Frequently Asked Questions (FAQs) About Music and Dementia
Q: Does listening to music every day lower dementia risk?
A: Yes. In a large study of adults aged 70 and older, people who always listened to music had a 39% lower risk of dementia and a 17% lower risk of cognitive impairment compared to those who didn’t listen as frequently.
Q: Is playing a musical instrument protective against dementia?
A: Yes. Older adults who often played an instrument showed about a 35% lower risk of developing dementia, although the benefits for specific thinking skills were less consistent than with listening.
Q: What kind of music works best for people with Alzheimer’s disease?
A: There’s no single “best” genre. Music that feels familiar and emotionally meaningful tends to work best, especially songs from earlier life that can spark memories and create a sense of calm and comfort.
Q: How often should older adults listen to music for brain health?
A: The biggest benefits were seen in people who listened regularly instead of occasionally. Making music a daily habit appears more important than the length of each session.
Q: Can music help reduce agitation or sundowning in dementia?
A: Yes, it can. Studies described in the article show that personalized music listening reduced agitation, anxiety, and irritability in people with dementia, especially compared to generic background music.
Q: Does singing in a choir help memory in older adults?
A: Singing in a choir may be helpful because it combines music with social interaction, focus, and routine. Researchers highlight group music activities as a promising way to support healthy aging and cognitive resilience.
Q: Is it too late to start learning an instrument to help the brain?
A: No. Starting later in life can still be beneficial. Even simple instruments or beginner practice engage attention, coordination, and creativity, all of which support brain health.
Q: How does music affect memory centers in the brain?
A: Music activates several brain networks at once, including those tied to memory, emotion, and attention. Familiar music strongly stimulates the medial prefrontal cortex, a region that often remains active longer in Alzheimer’s disease.
Q: What’s the difference between music therapy and casual listening?
A: Casual listening is informal and self-guided, like enjoying a favorite playlist at home. Music therapy is more structured and intentional, often used in care settings to support mood, behavior, or neurological recovery.
Q: Are there any risks to using music for people with dementia?
A: The main concern is overstimulation. Keeping the volume low, choosing familiar songs, avoiding sudden changes, and stopping if distress appears helps make music a beneficial and soothing experience.

Could the Shape of Your Behind Reveal a Hidden Health Risk?
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2026/01/06/sedentary-lifestyle-effects.aspx
Analysis by Dr. Joseph Mercola January 06, 2026
Story at-a-glance
- Americans spend about nine hours sitting and nearly five hours on their phones daily, contributing to a sedentary way of life
- In a featured study presented at the Radiological Society of North America (RSNA), researchers found that muscle shape, not size, may reveal early metabolic changes and even signal disease risk
- The World Health Organization (WHO) advises getting at least 150 minutes of moderate activity or 75 minutes of vigorous activity each week. Yet many people fall short of these targets because inactivity significantly raises the risk of cardiovascular disease, Type 2 diabetes, and other cancers
- Long, unbroken sitting bouts are associated with circulation problems, back pain, brain fog, higher cancer risk, and an increased risk of Type 2 diabetes
- Shape yourself up for better health by standing more, walking whenever you can, eating a nutritious diet, and getting enough sleep and sunlight
Americans are tired — 44% of employees are feeling burned out at work1 and about a third of adults sleep less than seven hours a night.2 Dragging through the day with too little rest, many end up doing the only thing that feels possible: staying seated. Roughly 80% of jobs are sedentary,3 and adults now spend close to nine hours a day sitting.4
People sit at work, sit on the commute home, then collapse on the couch only to stream a movie or idly scroll on their phones for three to five hours to recover from the stress of the day.5 While this kind of self-soothing to fight hustle culture may feel comfortable at first, it can shape your overall health for the worse.
With this thought in mind, researchers are now asking what shapes people’s health. Beyond habits and numbers, even the contours of the body may hold clues about what’s happening inside.
How the Shape of Your Buttocks Could Signal Diabetes Risk
The featured study, presented at the Radiological Society of North America (RSNA) Annual Meeting, analyzed more than 61,290 MRI scans from the UK Biobank database to explore how the shape of the gluteus maximus — the largest muscle in the buttocks — changes with aging, lifestyle, frailty, and Type 2 diabetes.6
• What sparked this research? Researchers suspected that muscle shape might reveal more about health than fat content. “Unlike past studies that mainly looked at muscle size or fat, we used 3D shape mapping to pinpoint exactly where the muscle changes, giving a much more detailed picture,” said Marjola Thanaj, Ph.D., senior research fellow at the University of Westminster’s Research Centre for Optimal Health.7
• What did MRI mapping reveal? The results showed two patterns: “outward deformation” linked to higher fitness and “inward deformation” tied to aging, frailty, and sedentary time. Thanaj said:8
“People with higher fitness, as measured by vigorous physical activity and hand grip strength, had a greater gluteus maximus shape, while aging, frailty, and long sitting times were linked to muscle thinning.”
• What did they discover about diabetes? In participants with Type 2 diabetes, men showed muscle shrinkage, while women had enlarged gluteus maximus muscles — likely due to fat infiltration. These gender-specific changes suggest men and women respond differently to the same disease.
“Shape changes in the gluteus maximus may indicate early functional decline and metabolic compromise in people with Type 2 diabetes,” Thanaj noted.9
• Frailty also left its mark — The research showed that men categorized as frail had widespread muscle thinning, while women showed smaller, localized changes. These findings highlight how muscle shape could reflect overall resilience and health status.10
• Why does this matter? The gluteus maximus is one of the body’s largest muscles and plays a key role in metabolic health. According to lead author E. Louise Thomas, Ph.D., professor of metabolic imaging at the University of Westminster’s School of Life Sciences, these shape changes may help identify early signs of metabolic compromise before other symptoms appear.11
A Global Picture of Physical Inactivity
Physical activity is one of the most potent ways to prevent chronic disease and support mental well-being, yet people are moving less than ever. According to the World Health Organization (WHO), about 1.8 billion people (31% of adults) failed to meet recommended activity levels in 2022.12
Since 2010, global inactivity has climbed by 5 percentage points, and this trend shows no signs of slowing. If it continues, inactivity could reach 35% by 2030, putting millions at risk for diseases that shouldn’t happen in the first place.
• People don’t meet movement quotas — The WHO advises getting at least 150 minutes of moderate activity or 75 minutes of vigorous activity each week. Yet many people fall short of these targets, significantly raising their risk of cardiovascular disease, Type 2 diabetes, breast and colon cancer, cognitive decline, and more.13
• Inactivity isn’t spread evenly across the globe — Some regions are far more affected than others. High-income Asia Pacific tops the list with 48%, followed closely by South Asia at 45%. Compare that to 28% in high-income Western countries and just 14% in Oceania.14
• Women and older adults move less — Globally, 34% of women are inactive compared to 29% of men, and adults over 60 are the least active — a troubling trend given the importance of movement for healthy aging.15
• Common barriers keep people from moving — Physical activity includes any movement, such as walking, cleaning, or gardening, while exercise refers to structured workouts. But even with these options, many people struggle to stay active due to low motivation, busy schedules, stress, or because they simply don’t enjoy the activity.16

Signs of a Sedentary Life
When most people hear “sedentary,” they picture someone who never sets foot in a gym. But the truth is far more nuanced. Researchers define a sedentary lifestyle as spending most of your waking hours sitting, reclining, or lying down, while expending very little energy — typically less than 1.5 metabolic equivalents (METs).17 Below are common signs:
• You feel consistently tired — It’s easy to blame fatigue on a packed schedule, but chronic tiredness often stems from inactivity. When you move very little, your heart, lungs, and muscles gradually lose conditioning. Ironically, the less you do, the more exhausted you feel.18
• You start gaining weight — Hours of sitting translate to fewer calories burned and a slower metabolism. Over time, this can lead to subtle but steady weight gain, especially around the midsection.19
• You get sad easily — Because of your lack of movement, your mental health might take a downturn, since staying still does not allow your body to make feel-good hormones.20
There’s nothing wrong with sitting down and taking a break because your body needs moments of rest. But the problem begins when those breaks stretch into hours and become your default state.
Prolonged Sitting Is Linked to Serious Health Problems
Spending hours in a chair every day doesn’t just leave you “a little stiff.” Research shows that prolonged sitting can affect nearly every major system in your body negatively, as it:
• Slows your circulation — When you sit for long stretches, blood and fluid tend to pool in your legs. This can lead to swelling, heaviness, and, in severe cases, increased clot risk.21
In a landmark population-health review in Exercise and Sport Sciences Reviews, researchers determined the risk of venous thromboembolism (VTE) associated with prolonged work- and computer-related seated immobility, saying:
“Prolonged work- and computer-related seated immobility increases the risk of VTE. We suggest that there needs to be both a greater awareness of the role of prolonged work-related seated immobility in the pathogenesis of VTE, and the development of occupational strategies to decrease the risk.”
• Wrecks your posture, spine, and glutes — Hours of slouching at a desk overload your spine, tighten hip flexors, weaken your core, and even “switch off” your glute muscles.22
In a 2020 study published in Medicina (Kaunas), 30 adolescent participants were asked to sit in a slumped posture for 30 minutes while using a mobile device. Electromyography showed no significant change in trunk muscle fatigue.23
Still, adolescents with chronic lower back pain reported significantly greater back discomfort than healthy peers, leading the authors to conclude that prolonged slumped sitting increases the risk of lower back discomfort, especially in those who already have pain.24
• Nudges your brain toward fog and memory problems — Spending too much time sitting doesn’t just affect your body; it can cloud your mind.
Researchers from Iowa State University surveyed more than 3,000 adults from all 50 U.S. states during the first months of COVID-19. People reported how their sitting, screen time, and exercise had changed since the pandemic, and rated their mental health. According to the researchers:25
“In the second study, we found that, on average, people saw their mental health improve over the eight-week period … People adjusted to life in the pandemic. But for people whose sitting times stayed high, their depressive symptoms, on average, didn’t recover in the same way as everyone else’s.”
• Raises your long-term cancer risk — Prolonged sitting is now recognized as an independent risk factor for several cancers, right alongside diet and smoking.
A study in Cancer Causes & Control followed 22,097 postmenopausal women for about eight years using accelerometers to track sitting time. Every additional two hours of daily sitting was linked to roughly a 6% increase in overall cancer risk, and longer, unbroken sitting bouts were especially associated with higher risks of breast, lung, and endometrial cancers. The researchers’ recommendations are:26
“These findings add to a growing body of evidence indicating that limiting sedentary behaviors may help reduce risk of cancers. Additionally, our results support public health messaging encouraging older adults to sit less and move more throughout the day to promote healthy longevity.”
• Damages your heart and metabolism — Sitting for long periods is strongly linked to higher blood pressure, poor blood sugar control, larger waistlines, and an increased risk of heart disease and diabetes even if you exercise regularly.27
An 11-year follow-up from the Norwegian HUNT Study, published in Diabetologia, tracked 28,051 adults to see who developed type 2 diabetes. Overall, people who sat for eight hours or more a day had about a 17% higher risk of diabetes than those who sat for four hours or less. When researchers looked only at people who were very inactive in their free time, they concluded that:28
“Our findings suggest that total sitting time has little association with diabetes risk in the population as a whole, but prolonged sitting may contribute to an increased diabetes risk among physically inactive people.”29
Can You ‘Out-Exercise’ the Bad Effects of Prolonged Sitting?
It’s tempting to think that a daily workout cancels out hours spent sitting. Unfortunately, research shows that’s not how the body works. Exercise is important, but it doesn’t erase the damage caused by being sedentary. Here’s why:
• Exercise can’t undo the harm of sitting — Health benefits come from pairing structured workouts with frequent movement throughout the day. A single gym session doesn’t offset eight hours in a chair because your body needs to stand, feel like it’s shifting postures, and needs to move.
• Sitting too much can cancel out the benefits of exercise — A systematic review of 47 studies on sedentary behavior, published in the Annals of Internal Medicine, found that spending long hours sitting each day causes harmful effects that outweigh the positive impact of physical activity.30
• Sedentary habits raise your risk of early death even if you work out — A 2015 study in PLoS One found that people who rarely exercised and sat for long periods faced a higher risk to their health.31
“Both high levels of sedentary time and low levels of moderate to vigorous physical activity are strong and independent predictors of early death from any cause,” the researchers said. “Whether a high physical activity level removes the increased risk of all-cause mortality related to sedentariness requires further investigation.”
A rigorous exercise routine may help prevent disease, but it’s not enough on its own — it’s best to add small movements throughout the day. Walking is the easiest — it’s free, safe, and hard to overdo. For more tips, read “Whether You Count Steps or Time Your Walk, What Matters Is Getting Outdoors.”
How to Stand Up, Shape Up, and Get Healthier
If you’re worried about getting sick — especially if you know you have a family history or genetic risk for Type 2 diabetes, heart problems, or other chronic diseases — spending less time sitting down in front of the TV is one of the simplest ways to take control of your health.
1. Move every 30 minutes — Even if your job or lifestyle involves sitting, make an effort to break it up. Set a reminder to stand up and move around every half hour. Walk around your house, climb stairs, or step outside for fresh air. Invest in a standing desk or walking pad to help you stay active, even if you’re working. Short bursts of activity help your circulation and prevent dangerous blood pooling in your legs. I do this myself and notice better energy and clearer focus throughout the day.
2. Incorporate walking into your lifestyle — Whenever you can, walk instead of driving or sitting. If you’re making a phone call, walk while you talk. Park further from the entrance when you run errands. If you have a dog, add an extra loop to your usual walk. Walking doesn’t require gym memberships or fancy equipment — it’s free, easy, and one of the most effective ways to lower your heart disease risk.
3. Make smart food swaps — Your brain runs on energy, and when your cells don’t get enough, mood issues like anxiety and depression can creep in. Start by fueling up with easy-to-digest carbs like fresh fruit and white rice. Most people do well with around 250 grams a day, and if you’re active or athletic, you’ll likely need more.
Just as important is to ditch seed oils and processed foods loaded with linoleic acid (LA), which can harm your mitochondria. Instead, cook with stable fats such as grass-fed butter, ghee, or beef tallow — they’re far better for your cells and overall health.
4. Let early morning sunlight reset your body and mind — Natural light in the morning boosts your endorphins, lifts your mood, and recharges your cells. Try to get outside every day, especially in the morning, to help reset your internal clock.
5. Restore balance with sleep and calm — Sleep is when your body repairs and resets. Without it, your emotional health suffers. Step outside soon after waking to anchor your circadian rhythm, and at night, create a wind-down routine: Dim the lights, skip screens, and keep your bedroom completely dark.
Frequently Asked Questions (FAQs) About Prolonged Sitting
Q: Why are so many Americans exhausted but still sitting all day?
A: Many Americans are running on empty. About 44% of employees feel burned out, and a third sleep less than seven hours. When you’re that tired, movement feels impossible, so most people default to what’s easiest: sitting almost all day.
Q: What did researchers at the Radiological Society of North America (RSNA) find out about the gluteus maximus?
A: They analyzed over 61,000 MRI scans from the UK Biobank and mapped the gluteus maximus in 3D. They found shape changes linked to fitness, aging, frailty, long sitting, and Type 2 diabetes, suggesting buttock muscle shape reflects underlying metabolic health.
Q: How much movement does the World Health Organization (WHO) recommend?
A: The WHO recommends at least 150 minutes of moderate activity or 75 minutes of vigorous activity weekly, but many people still have difficulty reaching that threshold.
Q: What serious health problems are linked to prolonged sitting?
A: Prolonged sitting slows circulation and increases blood clot risk, worsens back pain and posture, and is tied to higher rates of depression, anxiety, cancer, heart disease, larger waistlines, poor blood sugar control, and Type 2 diabetes, especially in inactive people.
Q: Can you immediately offset the effects of prolonged sitting?
A: No. Studies show long sitting still raises your risk of early death, heart disease, and diabetes even if you exercise. Your body does best when formal workouts are combined with frequent movement breaks and regular walking throughout the day.

What Makes All Vaccines So Dangerous?

Analysis by A Midwestern Doctor January 09, 2026
Story at-a-glance
- Vaccines often cause various side effects, making it hard to identify common causes — many of which overlap with other mysterious and “incurable” ailments
- Neurologist Andrew Moulden discovered that vaccines frequently trigger microstrokes, which can lead to a myriad of acute and chronic diseases
- Forgotten research from the 1960s shows that blood cell clumping is a root cause of many diseases — a belief also shared by Chinese Medicine
- Colloidal chemistry and zeta potential science reveal that positive charges around blood cells cause clumping. Agents with concentrated positive charges, such as aluminum and the COVID spike protein, are especially problematic
- Improving the physiologic zeta potential benefits a wide range of acute and chronic illnesses. A strong case can also be made that many conventional and holistic therapies work in part by enhancing zeta potential
Many medical problems stem from the diagnostic approach of physicians, especially with complex illnesses, which are often misdiagnosed and lead to ongoing patient struggles.
Complex conditions can present with varied symptoms across patients and resemble other illnesses (e.g., fibromyalgia vs. chronic fatigue syndrome). In turn, poorly trained physicians often default to psychiatric explanations, overlooking the actual causes.
As vaccine injuries have a wide range of symptoms, they have hence confused doctors for over 200 years (with many doctors in the past labeling them as “encephalitis”). Presently, I believe three main mechanisms underlie the myriad of chronic illnesses including vaccine injury:
• Immune dysfunction — Vaccines frequently cause chronic autoimmune disorders and varying degrees of immune suppression.
• Impaired circulation — Vaccines can impair fluid circulation by affecting the body’s zeta potential. This causes fluid clumping (i.e., micro blood clots and blood thickening) and obstructs blood flow in capillaries. Likewise, other factors can as well, and I believe one of the primary issues with COVID-19 and vaccine spike protein is that it carries a strong positive charge density, which triggers clumping in fluids throughout the body (hence why the vaccine became known as the “clot shot”).
• Cell danger response — When shocked, such as from a toxin or loss of blood flow, cells can enter a primitive state under threat, stopping normal mitochondrial function and creating inflammation. This temporary state can become chronic, underlying many severe conditions (particularly those which worsen rather than improve with treatment).
Treating this response has resolved conditions linked to vaccination, like autism, and, in complex illnesses, restoring health often requires first addressing the underlying cause of a patient’s illness and then resolving the cell danger response it triggers.
Note: While not the most potent tool for addressing each of these root cause illnesses, DMSO stands out for its broad therapeutic activity, which allows it to address all three.
This, I believe, accounts for why thousands of readers here have reported it was able to cure a myriad of seeming unrelated illnesses which did not respond to other therapies, but likewise why a fraction of people with those illnesses which typically responded to DMSO did not have a disease resolution from DMSO alone (as they required a stronger therapy to target the root cause of their illness).
While I always consider all three of these factors, I’ve long placed particular weight on circulatory obstructions, and I’ve long believed that patient outcomes would significantly improve if the medical system recognized and prioritized the zeta potential.
Andrew Moulden
Andrew Moulden was a Canadian neuroscientist and doctor specializing in neuropsychiatry. During his clinical training, he noticed that young children exhibited subtle neurological signs of stroke that his colleagues missed. Over time, he found these strokes often occurred soon after vaccination and could lead to severe neurological disorders like autism.
Note: Vaccine injury reports dating back to the early 1800s contain the same signs Moulden observed.
Moulden realized that the subtle stroke signs doctors look for in adults should also be assessed in children. Because these strokes in infants are often missed, many conditions are misdiagnosed or attributed to unknown causes. A major scientific challenge is making invisible issues visible. However, in neurology, disruptions in brain function, often due to impaired blood flow, can reveal stroke locations through careful physical examination.
Moulden found that cranial nerves in the brainstem, particularly in watershed areas with less redundant blood supply, were vulnerable to these strokes. Those strokes, caused by impaired blood flow, often due to increased blood thickness, were missed in infants, leading to conditions misdiagnosed or attributed to “unknown” causes. Key cranial nerves indicating vaccine-caused microstrokes (due to their blood supply) include:
• Cranial Nerve VI — Controls eye movement; damage causes inward eye resting or jerky side-to-side movement.1
Note: We’ve found CN VI is the nerve most frequently affected by COVID-19 injuries and I’ve lost count of how many people I know who developed subtle abnormalities in it after vaccinating.
• Cranial Nerve VII2 — Controls facial muscles; damage causes Bell’s Palsy,3 facial drooping, or asymmetry (e.g., this appeared to have happened to Justin Bieber during the COVID-19 vaccine campaign).
• Cranial Nerve IV — Levels eyes; damage causes head tilting to compensate for uneven eye height.4
Note: Often, you will see multiple cranial nerve issues on the same face (which suggests more parts of the brain lost their blood supply and hence that deeper neurological damage is also present). For example, cranial nerve deficits have long been observed after vaccine injuries and in autistic children.
Consider the case below of triplets who all received a hot pneumococcal vaccine,5,6 and in a few hours all had their cranial nerves stop functioning after which they rapidly became severely and permanently autistic — making it nearly irrefutable that this process caused their autism.
Once you know how to look for these symptoms (e.g., a loss of smooth eye motion), they are very easy to spot, and you will gradually become aware of how far-reaching the neurological damage resulting from vaccination can be (since any part of the brain can be affected). For example, these were two similar pictures readers sent in of their children who became severely disabled after vaccination.
Note: While cranial nerve issues are easiest to detect through observed motion, as the above pictures show, some of them can also be seen in static images. Remarkably, if you look at much older photos, facial asymmetries were much rarer. These pictures, for example, were collected by Forest Maready and mirror what I’ve seen (e.g., by looking at the walls of medical school class portraits and noticing how faces changed over the decades).7
Note: Decades of suppressed evidence link vaccines to sudden infant deaths. Moulden observed inward eye deviation before death and proposed vaccine-induced microstrokes affecting the CN VI nucleus disrupt the brain’s nearby respiratory center. Subsequent ICU studies show vulnerable infants can experience post-vaccination breathing cessation — survivable if monitored, fatal if unnoticed.”
Moulden’s work also suggested strokes were occurring in other watershed areas of the body, such as internal organs and speech centers. Evidence included:
• Autopsy studies show strokes in the internal organs of children with congenital rubella.
• Similar disease processes in teenagers and adults after HPV or anthrax vaccination (two particularly harmful vaccines).
• One of the most striking examples was the children of soldiers who received the anthrax vaccine and were born without limbs8 (thalidomide was also notorious for doing this by blocking the formation of new blood vessels9).
• Neurodegenerative processes in the elderly and psychiatric disorders being linked to detectable cranial nerve damage (something many of us also tragically witnessed after COVID vaccination).
Note: A major issue in conventional medicine is the failure to recognize that neurological damage can lead to psychiatric issues. Consequently, emotional changes in patients with nervous system injuries are often misattributed as the cause rather than a symptom of their illness.
Moulden thus began exploring which universal response was causing these microstrokes and how they could be treated. From this, he produced three videos describing the problem (which can be viewed here). Unfortunately, shortly before releasing a second series on the solutions for these injuries, he died under suspicious circumstances. However, we now have many clues as to what Moulden discovered.
Blood Sludging
In the medical world, a long-standing puzzle revolves around how small insults to the body can lead to widespread illness or even death. One key factor in this equation is blood sludging, a phenomenon observed for centuries where the blood clumps together and thickens under certain disease conditions. Melvin Knisely, Ph.D., in the mid-20th century made critical discoveries about this phenomenon.10
Knisely’s research, particularly with malaria-infected monkeys, revealed that certain severe illnesses could trigger significant blood sludging, starting in small vessels and eventually spreading to larger ones, which was typically fatal (unless prevented with the anticoagulant heparin).11 This thickening of blood can be likened to traffic jams, disrupting the body’s natural blood flow, and eventually leading to gridlock (death).
Additionally, he discovered that this systemic sludging could be seen externally through the eyes, providing a noninvasive way to assess this process throughout the body.
From this, Knisely discovered the greatest blood sludging was seen in critically ill hospital patients — something Pierre Kory, MD, also observed with point-of-care ultrasound, as once micro clots within the IVC became echogenic (visible), patients died shortly after.12 Likewise, multiple ultrasound researchers’ results showed blood sludging within patients.13,14
After learning of this, we attempted to replicate Knisely’s microscope and have been able to see the same sludging he observed 80 years ago in his patients. This video, for example, was taken from the eyes of a COVID-19 vaccine-injured patient:
Video Link
Likewise, this concept exists in other medical systems. Chinese Medicine, for example, ever since the (zeta potential-obstructing) smallpox vaccine was released, has come to view blood stasis as a primary cause of illness, and much of their blood stasis framework directly overlaps with the blood sludging model.
Note: Blood sludging was frequently observed in burns (which I believe explains why zeta potential restoring therapies and DMSO are so helpful for burns).

Zeta Potential
When particles are placed in water, one of three things can happen:
• They don’t mix (e.g., oil floats to the top, sand sinks to the bottom).
• They dissolve (e.g., salt).
• They form a colloidal suspension (e.g., milk) in which each particle is repelled from the other and evenly distributed.
In the case of colloidal suspensions, their stability is determined by what causes their particles to come together (gravity separating things by weight, the inherent molecular attraction between objects), and what pushes them apart.15
The first method (zeta potential alteration) refers to the difference in charge between the water ions (which coat the colloidal particles) and the surrounding water.
Because electrical repulsion due to zeta potential is easier to adjust externally, it is typically the factor focused on when trying to improve colloidal dispersion (e.g., to eliminate blood sludging).
One of the most effective agents for collapsing zeta potential is aluminum (which explains why it’s frequently used to separate organic matter from water in sewage plants or to clot bleeding wounds). Moulden thus concluded that aluminum’s widespread use in vaccines likely accounted for many of their side effects. Similarly, consider the effect the COVID-19 vaccine’s spike protein has on the blood.16
The key thing to understand about zeta potential is that when its repulsion no longer suffices to overcome the attractive forces in a colloidal system, it will clump together, initially in small clumps (termed agglomerations), and then as the zeta potential worsens, form larger clumps.
Note: The normal zeta potential of a red blood cell is around -15.7 millivolts.17 Additionally, as red blood cells age, they lose their negatively charged sialic acid, which worsens their zeta potential.18
Thomas Riddick, a pioneer in this field, discovered that the body maintains blood zeta potential near the agglomeration threshold so it can clot in case of bleeding.19 With further study, Riddick found the degree of blood sludging or loss of physiologic zeta potential significantly varied from person to person (due to modern life disrupting it), and Knisely’s grading scale for blood flow in the eyes could be used to accurately predict who was at risk of an arrhythmia, a stroke, or a fatal heart attack.20
Most importantly, Riddick discovered that once the colloidal dispersion of the blood was fixed, heart arrhythmias normalized, and circulatory problems greatly improved.
Note: Many readers have shared with me that restoring their zeta potential improved their atrial fibrillation.
Riddick gradually discovered blood sludging was widespread in America and eventually concluded our food and water supply were contaminated with positive ions that were destructive to zeta potential. He attributed this to:
• Potassium is being replaced by sodium in processed foods
• Aluminum is being used in municipal water systems
• Aluminum kitchenware
• Aluminum is being added to many foods (e.g., most salt has aluminum added to keep it from caking)
• Many medications (e.g., antacids) are full of aluminum and other problematic metals
• Many foods are stored in metal cans (acidic foods leach these metals)
Note: The first head of the FDA fought to stop aluminum from entering general use but was muscled out by industry.21
Riddick also performed experiments that showed consuming water stored in metallic aluminum significantly impaired microcirculation. Sadly, we are now witnessing an increasing trend of storing water in aluminum cans (but fortunately, a few zeta-potential restoring bottled water brands still exist — which a few readers have shared dramatically improved their health, illustrating how sensitive some individuals can be to minor improvements in zeta potential).
Lastly, in addition to these, I believe EMFs, certain chronic infections, and humanity’s lack of electrical grounding to the Earth are significantly impairing humanity’s zeta potential.22 Likewise, I believe Riddick’s model (like many preliminary ones) was incomplete as he never accounted for the effect mass vaccination was having on zeta potential.
Note: I believe Knisely’s observations of profound blood sludging in the eyes of severely ill hospital patients account for why IV saline (which improves zeta potential) so frequently benefits people who are sick enough to require hospitalization. Likewise, Knisely also observed that certain agents, such as hydroxychloroquine, reversed blood sludging.
This led him to suspect a significant degree of the anti-malarial benefit of hydroxychloroquine actually arose from it reducing blood sludging; I also suspect this property may account for hydroxychloroquine’s value in treating autoimmune conditions and COVID-19 (both conditions linked to poor zeta potential).
Vaccines, Microbes, and Zeta Potential
Riddick also concluded that bacterial metabolism of proteins lowers their zeta potential by decarboxylating them.
Many sewage treatment systems (e.g., septic tanks) work under this principle, as over time, decarboxylation (which removes negative charges) destroys the colloidal stability of the organic matter suspended in wastewater, causing it to sludge at the bottom where it can later be removed and disposed of (in many cases unfortunately ending up in our soil as a “fertilizer” — which creates a host of subsequent issues).
Riddick next assessed how zeta potential changed in humans during acute infections. Much like Knisely had observed in the eyes of his acutely ill patients, Riddick consistently observed a decrease in physiologic zeta potential there during an infectious condition.
These observations were important because they provided a means to explain why the elderly (who cannot tolerate a further drop in their zeta potential without passing into the agglomeration threshold) are so much more vulnerable to infections like influenza (rather than simply feeling crummy from an unpleasant but manageable increase in fluid stagnation).
Sadly, it also likely explains their greater susceptibility to vaccine injuries (e.g., I’ve admitted a few patients to the hospital who suffered a classic zeta-potential collapse from a pneumococcal vaccine and readers here have shared a few similar examples).
Lastly, many microbes carry positive charges, which allow them to adhere to the negatively charged surfaces of the body. These hence cause them to disrupt zeta potential once they’ve sufficiently reproduced in the body.
This is a major problem in Lyme disease and chronic mold toxicity, which in part explains why therapies for those diseases often fail unless something (e.g., treating zeta potential) is also done to address the fluid stagnation they create (particularly within the lymphatics, which is required to drain the released toxins so herxheimer reactions do not occur). Fortunately, there are many ways to address this.
Ozone, for instance, oxidizes those charges, and I believe this accounts for the dramatic improvements sometimes observed after one receives an oxidative therapy.
Similarly, a 2022 paper that showed the spike protein directly impaired blood cell zeta potential also found that ivermectin dispersed blood cells, in which the spike protein had clumped together (which may explain the instantaneous normalization of vital signs sometimes seen after ivermectin is given to severely ill hospital patients).23
Protein Misfolding
Since folded proteins are essentially colloidal suspensions, ions that disrupt zeta potential can also cause protein misfolding and denaturing (something that also happens to egg whites when they are heated in a pan). I believe this is a key reason why the plaques found in Alzheimer’s disease (which are misfolded proteins) are found to contain aluminum.24
Likewise, the COVID spike protein (produced by the vaccines) has been linked to protein misfolding diseases such as Creutzfeldt-Jakob Disease, amyloidosis, and unusual fibrous (amyloid) clots embalmers have found within the vaccinated, which appear to result from misfolded clotting proteins the body can’t break down.25
Note: I have now received reports of those conditions (including CJD) responding to DMSO.
Lastly, it is critical to recognize that this zeta potential applies to many fluids besides blood, and I believe its ability to alter lymphatic and cerebrospinal fluid circulation plays a major role in why:
• Zeta potential regimens can eliminate toxins such as neurodegenerative protein deposits and improve cognition.
• Chinese medicine attributes blood stasis to autoimmunity, as congested lymph fluid creates inflammation.
Likewise, other critical properties for health (e.g., sufficient water within the body existing in a negatively-charged liquid crystalline state) also go hand-in-hand with the existing physiologic zeta potential.
Conclusion
Healthy fluid circulation is essential for health, and the zeta potential concept begins to explain why so many different conditions can lead to similar symptomatology. In the case of vaccines, this model explains why:
• Vaccines consistently cause harm.
• There is so much variability in vaccine injuries.
• Vaccine damage is cumulative, as existing impairment of the microcirculation (and other fluid circulations) will progressively worsen with each successive vaccine.
• Many infectious diseases can sometimes cause similar (but not as severe) injuries as vaccines.
Likewise, it’s critical to recognize that less severe impairments of zeta potential can also have significant physiologic consequences, and that a strong argument exists many of the consequences of aging (e.g., cognitive impairment and increased frailty) ultimately result from increasing disruption to the physiologic zeta potential as aging kidneys lose the ability to selectively excrete problematic ions (which is why longevity doctors had so much success averting cognitive decline with simple zeta potential regimens).
The zeta potential concept profoundly changed my medical practice, and I now believe that many effective holistic therapies work in part because they can restore physiologic zeta potential.
Once you know to look for it, it is truly eye opening how many different illnesses result from fluid stagnation within the body and how much hospital care could be improved by monitoring for zeta potential shifts.

New Research Explains Why Some Minds Stay Awake at Night

Analysis by Dr. Joseph Mercola January 03, 2026
Story at-a-glance
- Insomnia keeps your mind in daytime problem-solving mode at night, which prevents the natural mental drift that helps you fall asleep
- New research shows that people with insomnia have weaker circadian signals, making it harder for the brain to shift from alert thinking into the dream-like patterns that support rest
- Sequential thinking stays elevated at night in insomniacs, creating racing thoughts and mental loops that make it difficult to unwind
- Strengthening your circadian rhythm through morning light exposure, dim evening lighting, and consistent nighttime cues helps your brain recognize when to power down
- Simple practices such as cognitive shuffling, sensory-based grounding during nighttime awakenings, and daily movement — especially walking — support a clearer day-night contrast and more restorative sleep
A growing number of adults describe the same frustrating pattern: they feel worn out, yet their minds refuse to settle when they finally lie down. That experience lines up with a well-defined sleep disorder. Insomnia is a condition marked by trouble falling asleep, staying asleep, or returning to sleep after waking. You might recognize the signs yourself — racing thoughts, tension in your chest, early awakenings, or a sense that your mind stays awake even when your body feels drained.
Over time, this disorder affects your mood, your ability to think clearly, and the way your body responds to daily stress. A night of insomnia often follows the same script. Your body wants rest, but your thoughts hold you in a state that feels too alert. Instead of drifting into the loose, dream-like mental space that usually opens the door to sleep, you stay anchored in the same style of thinking you use during the day.
For many people, it feels like their brain keeps sorting, analyzing, or predicting long after they want it to power down. This creates a loop where bedtime triggers more thinking instead of less. Age adds another layer. If you’re an older adult struggling with sleep maintenance — waking and then staying awake — your internal timing signals may already be softer than they once were.
That makes it easier for your brain to slip into daytime patterns at night and harder to transition into restorative sleep. You wake feeling as though you never fully crossed the threshold into rest. All of this points to a deeper issue: something in the brain’s internal timing system keeps certain minds switched on long after the lights go out. A study published in Sleep Medicine sheds light on that exact problem.1
Why Your Mind Stays Locked in ‘Day Mode’ at Night
The Sleep Medicine study investigated whether people with sleep-maintenance insomnia struggle to shut off their thoughts at night because of underlying circadian rhythm abnormalities.2 The research team kept participants awake for 24 hours under controlled laboratory conditions to remove bedtime triggers, allowing them to measure pure, internal mental rhythms.
This setup helped the researchers identify whether insomnia reflects a built-in thinking pattern, a learned response to bedtime, or a timing problem in the brain’s internal clock. The participants were adults over age 55, separated into two groups: those who slept well and those who routinely woke during the night and struggled to return to sleep.
• Insomniacs showed flatter rhythms in key mental areas — For the study, insomnia was defined by at least 30 minutes of staring at the ceiling after waking up and less than 6.5 hours of total sleep time each night. These individuals showed clear differences in how their thoughts shifted throughout the day compared with the healthy sleepers, revealing why your mind might race long after you want it to quiet down.
One of the most important findings was that people with insomnia had weaker fluctuations in thought patterns that normally rise during the day and fall at night. In healthy sleepers, mental activity gradually shifts into more dream-like, disconnected content before sleep.
In contrast, the insomnia group showed smaller day-night swings in reality orientation and volitional control — two metrics that predict how easily your brain releases its grip on daytime problem-solving. The researchers wrote that insomniacs showed less 24-hour variation in these areas, meaning their thoughts didn’t wind down the way they should.
• Sequential thinking stayed elevated at night for those with insomnia — Another standout finding was the dominance of sequential thinking in the insomnia group — thoughts that continue in a logical chain: one idea triggering another, then another. The study found their baseline levels were higher, and the nighttime drop was smaller. This means your mind keeps behaving as if it’s still solving problems, rather than drifting into the random, image-based thoughts that help usher in sleep.
• The timing of mental “quieting” was delayed — The researchers found that the peak times for thought structure and volitional control occurred more than six hours later in the insomnia group. This means your internal switch from alertness to mental quiet doesn’t flip at the right time. When your brain stays locked on daytime settings, sleep feels out of reach no matter how tired your body feels.
Insomniacs Maintained More Real-Like Thinking During the Night
Healthy sleepers naturally shift into thoughts that feel unreal or dream-like as bedtime approaches. Insomniacs, however, showed a reduced drop in reality orientation. According to the study, the amplitude of this mental shift was significantly smaller, indicating their thoughts stayed anchored in real-world concerns instead of loosening into the surreal space that precedes sleep. This creates the feeling of lying in bed replaying conversations, planning tasks, or running through worries instead of drifting off.
• The ability to slow thoughts at night stays stuck in high gear — The study found that the degree of control people felt over their thinking didn’t fall as sharply at night for the insomnia group.
Your ability to direct or stop your thoughts normally dips before sleep. Insomniacs had a flattened rhythm and delayed timing, matching what the authors described as “continuing cognitive engagement.” This pattern aligns with a known mechanism called prefrontal hyperarousal, meaning the front of your brain remains active and goal-driven instead of powering down.
• Circadian mechanisms help explain why your mind refuses to shut off — The researchers identified that weakened circadian rhythms disturb the brain’s ability to shift gears.3 When your circadian amplitude is low, your brain receives a weaker signal telling it to reduce mental activity at night. The study suggests that strengthening circadian cues — like bright daytime light exposure — could help restore a clearer separation between day-mode and night-mode thinking.
• Insomnia isn’t just about worry or habits — It involves measurable disruptions in how your brain organizes thoughts across the day. Because sequential thinking and circadian flattening were key differences, the authors concluded that “modifying sequential thinking” and “strengthening circadian rhythmicity” could form the basis of future interventions.
This means your path forward is not just about calming your mind — it’s about helping your brain reclaim the natural 24-hour rhythm that supports healthy sleep.

How to Quiet a Mind That Refuses to Power Down
Your mind races at night for a reason. The research shows that the root problem is a weakened circadian rhythm in the parts of your brain that regulate thought patterns. That rhythm is supposed to dim the intensity of daytime thinking and shift your mind toward softer, dream-like mental activity.
When that dimmer switch barely moves, your thoughts stay linear and problem-focused long after you want them to quiet. The solution is to strengthen that rhythm and retrain your mind to release its grip on daytime processing. If you lie awake replaying conversations or solving problems at 2 a.m., these steps will help you take back control.
1. Strengthen your daytime light exposure to boost circadian rhythm strength — The study found that insomniacs had flatter rhythms, which means your brain is not receiving a strong enough signal to distinguish day from night. One way to improve that signal is by getting direct sunlight in your eyes early in the day. This gives your brain a clear message: this is daytime, so later you will shift into night mode.
Start with 10 to 15 minutes outside shortly after waking. To reinforce this contrast even more, dim your lights after sunset and shut off screens in the evening. If you rely on devices, lower the brightness or use warm, low-light settings so your brain doesn’t mistake nighttime for midday.
2. Build a personalized wind-down period that breaks sequential thinking — The research highlighted elevated sequential thinking at night, which is the chain-reaction style of thinking that keeps your mind running, in insomniacs. Dedicate a short period before bed to intentionally interrupting that chain.
One method that works well is cognitive shuffling, which helps transition your mind toward sleep by mimicking the brain’s natural shift from focused thinking into the looser, dream-like patterns that appear as you drift off.
Instead of trying to force your mind to go blank, choose a simple word and think of other words that start with each letter. This gently redirects overthinking without stimulating your brain. The technique offers just enough distraction to pull you out of racing thoughts while keeping your mind relaxed.
Adding light visualization or intentional breathing as you do it engages your senses and activates your body’s natural relaxation response. If you struggle with overactive thinking, this combination gives you a practical way to take control and lower your mental load before bed.
3. Use structured evening cues that tell your brain it’s time to drop into dream-mode — Your circadian system relies on predictable signals. If your evenings are inconsistent, your mind stays alert. Add small rituals that act as environmental cues: dim lights, warm shower, quiet music, or slow stretching. If you’re highly sensitive to stimulation, start with one or two cues and repeat them nightly. Consistency helps restore the rhythm that triggers your mental shift away from daytime cognition.
4. Break the habit of staying mentally “on” when you wake at night — Insomniacs in the study remained cognitively engaged even when they were lying still. If you tend to wake in the night, I recommend giving your brain a simple rule: return to sensory awareness instead of thinking. Notice your breath, the weight of the blanket, or the temperature of the room. This keeps you out of sequential thinking and prevents your mind from re-entering problem-solving mode.
5. Anchor your day with movement to reinforce the contrast between alertness and rest — A flat rhythm means your brain doesn’t feel the difference between day and night. Daily movement increases that difference and strengthens your internal timing. A review of 22 clinical trials found that yoga, tai chi, and walking were the top three forms of exercise for improving sleep quality, duration, and efficiency in people with insomnia, with walking showing the greatest reduction in insomnia severity.4
Moderate-intensity walking is especially useful because it’s gentle enough to repeat daily without the health risks tied to excessive vigorous exercise. A walk outdoors works even better because it pairs movement with natural light, which sharpens the day-night contrast your brain depends on.
If you tend to sit for long stretches, break your activity into two or three short walks. The goal is to show your brain through consistent behavior that daytime is active and nighttime is calm, helping you retrain your mental rhythms.
FAQs About Racing Thoughts at Night and Insomnia
Q: Why do some people feel mentally alert at night even when they’re exhausted?
A: Insomnia disrupts your brain’s normal timing cues, so the mental shift from daytime thinking to dream-like drifting doesn’t happen. Instead of quieting down, your thoughts stay structured, analytical, and alert long after you want to sleep.
Q: What did the Sleep Medicine study reveal about thought patterns in insomnia?
A: The study found that people with insomnia have flatter circadian rhythms, higher levels of sequential thinking at night, and delayed mental “quieting.”5 Their brains stay in problem-solving mode instead of transitioning toward the kind of loose, disconnected thinking that supports falling asleep.
Q: Why does sequential thinking make it harder to fall asleep?
A: Sequential thinking keeps your mind moving in a logical chain — one thought triggering the next. This creates the feeling of “thinking in loops,” which blocks your brain from shifting into the more random, dreamy patterns that ease you into sleep.
Q: How does weakened circadian rhythm contribute to insomnia?
A: When your circadian signal is weak, your brain doesn’t clearly distinguish day from night. That makes it harder to power down mentally at bedtime, which leads to racing thoughts, alertness at the wrong time, and fragmented sleep.
Q: What steps help restore healthy mental rhythms for better sleep?
A: Strengthen daytime light exposure, dim lights at night, and build consistent evening cues. Use cognitive shuffling to interrupt racing thoughts, avoid mental problem-solving during nighttime awakenings, and anchor your days with movement — especially walking — to reinforce the contrast between alertness and rest.
