Early Neurorehabilitation After Head Injury Lowers Alzheimer's Risk
Dr. Joseph Mercola - Take Control of Your Health
Early treatment within the first week after a moderate or severe head injury sharply lowers your long-term risk of Alzheimer’s disease and related cognitive decline Neurorehabilitation — including physical, occupational, cognitive and speech therapy — strengthens your brain’s ability to reorganize itself, improving recovery and long-term function at any age Acting quickly after a head injury reduces the chances of developing mild cognitive impairment, dementia, and the need for Alzheimer’s-related medications in the years that follow DMSO used in the early hours after injury helps...

What Phlegm Color Reveals About Your Respiratory Health
Dr. Joseph Mercola - Take Control of Your Health
Phlegm color shifts give you immediate clues about what’s happening in your airways, helping you judge whether irritation, inflammation or infection is building before symptoms intensify Yellow and green tones reflect immune activity, while pink, red, brown or black phlegm signal bleeding, long-standing lung issues or fungal infection, giving you clear markers for when to act quickly Sudden changes from your normal phlegm pattern matter more than the color itself, allowing you to use your personal baseline as a reliable guide for when something is wrong Texture changes — such as thick,...

Infrared Sauna After Training Speeds Recovery and Supports Athletic Performance
Dr. Joseph Mercola - Take Control of Your Health
Athletes using infrared saunas post-workout experience faster reductions in soreness, improved strength recovery, and better neuromuscular performance within 24 hours compared to passive rest Using infrared saunas immediately after exercise yields stronger results than delayed sessions, as it extends the body's natural repair window when circulation and metabolic signaling are elevated Consistent post-workout infrared sauna sessions over several weeks increase muscle thickness, explosive strength, and power output more effectively than training alone, especially for intermediate lifters...

Black Cumin Offers Broad Support for Chronic Disease Management
Dr. Joseph Mercola - Take Control of Your Health
Black cumin supports several root causes of chronic illness — including oxidative stress, inflammation, and poor metabolic control — giving your body broad protection where it needs it most Thymoquinone, black cumin’s most active compound, drives strong antioxidant, antimicrobial, and anti-inflammatory actions that help stabilize energy, immunity, and cellular function Research shows black cumin improves blood sugar, strengthens antioxidant defenses, and lowers inflammatory markers, offering support for diabetes, immune imbalance, and chronic fatigue Black cumin’s wide-ranging effects...

Inulin-Rich Prebiotic Vegetables May Help in Fatty Liver Disease Reversal
Dr. Joseph Mercola - Take Control of Your Health
Inulin is a naturally occurring, non-digestible fiber stored in many plants. It acts as a prebiotic, feeding beneficial gut bacteria that influence how the body handles sugar, fat, and inflammation A 2025 animal study found that inulin helped reverse fatty liver disease by prompting small-intestinal microbes to clear fructose and redirect liver metabolism toward the production of the antioxidant glutathione Inulin supports insulin sensitivity, lowers triglycerides, and improves liver markers. However, high doses, especially from supplements, can cause bloating Onions, garlic, asparagus,...

The Hidden Dopamine Trap — Escaping Screen Addiction to Reclaim Your Joy
Dr. Joseph Mercola - Take Control of Your Health
Modern children’s content (especially fast-paced YouTube shows like CoComelon) is engineered to maximize watch time through rapid cuts and constant dopamine triggers, creating addictive patterns in toddlers that lead to overstimulation, irritability, and severe tantrums, and when screens are removed This deliberate design exploits the brain’s orienting response, rewiring developing nervous systems toward novelty-seeking while impairing sustained attention, executive function, and emotional regulation — effects supported by studies linking fast-paced media to ADHD-like symptoms and...

Obesity-Linked Metabolic Stress in Young Adults May Trigger Early Brain Changes
Dr. Joseph Mercola - Take Control of Your Health
Early signs of brain damage linked to obesity are already showing up in young adults, decades before symptoms like memory loss or confusion begin Having low levels of choline, a nutrient most people don't get enough of, is strongly connected to inflammation, liver stress, and neuron injury in people with obesity Women are especially vulnerable to brain-related effects of metabolic stress, as they tend to have significantly lower choline levels than men A major brain imaging study confirmed that obesity directly causes brain shrinkage, white matter damage, and reduced cognitive performance —...

Exercise Trains Your Immune Cells to Stay Strong as You Age
Dr. Joseph Mercola - Take Control of Your Health
Exercise trains your immune system to respond faster and recover more efficiently, helping you stay energized and more resistant to illness Years of consistent moderate training reshape how your immune cells produce and manage energy, keeping them youthful and resilient as you age Active adults maintain steadier inflammation and bounce back quicker from stress, reducing fatigue, soreness, and lingering symptoms after illness Daily walking with short, high-quality strength sessions builds immune stability without overwhelming your system or spiking stress hormones Training your immune cells...

Keto Diet Risks Are Varied, Multiple Studies Show
Dr. Joseph Mercola - Take Control of Your Health
A ketogenic diet improves weight loss, insulin sensitivity, and blood sugar control initially, but these gains typically level off after six to 12 months of adherence Long-term keto can elevate low-density lipoprotein (LDL) cholesterol levels, particularly during rapid weight loss, raising cardiovascular concerns especially in healthy young adults following this diet Restricting carbohydrates eliminates healthy fruits, vegetables, and whole grains, leading to deficiencies in essential vitamins (B-complex, A, E, K) and minerals like magnesium and potassium Extended ketogenic diet use increases...

Microplastics Could Be Weakening Your Bones, New Study Finds
Dr. Joseph Mercola - Take Control of Your Health
A recent Osteoporosis International review summarized multiple studies showing that microplastics have been detected in human bone tissue, where they disrupt bone cell activity, trigger inflammation, and weaken structural integrity Laboratory and animal studies show microplastics accelerate osteoclast activity and alter bone microarchitecture, linking environmental plastic exposure to rising rates of bone fragility and dysplasia Microplastics are not limited to bone; previous research has also detected them in the bloodstream, brain, placenta, heart, lungs, liver, kidneys, and reproductive...
info_outline- New research shows that people with untreated sleep apnea experience a sharp nighttime drop in blood vessel function driven by the circadian system, increasing vulnerability to heart attacks and other cardiac events
- In a tightly controlled sleep-lab study, participants’ arteries showed their worst ability to dilate around 3:00 a.m., revealing an 82% decline in vascular function during the biological night
- This impairment persisted even after adjusting for blood flow, sleep quality, and apnea severity, confirming the circadian system — not behavior or breathing events — directly weakens vascular health at night
- The findings help explain why people with sleep apnea experience more nighttime cardiac events, contrasting with the general population’s morning peak in heart attacks and sudden cardiac death
- Researchers emphasize that understanding circadian timing may help refine cardiovascular treatments for sleep apnea patients, including optimizing medication schedules to enhance nighttime vascular protection
