Dr. Joseph Mercola - Take Control of Your Health

Type 2 diabetes management is influenced not only by diet and medication but also by environmental factors, including the type and timing of light exposure during typical indoor workdays
A Cell Metabolism study found that participants exposed to natural daylight spent more time within a healthy glucose range than those exposed to standard office lighting
Daylight supports circadian alignment by strengthening communication between the brain's master clock and peripheral clocks in organs that control insulin sensitivity, glucose uptake, and energy metabolism
Natural daylight also shifted how the body used energy and improved metabolic flexibility, which plays an important role in long-term insulin sensitivity and glucose regulation
Simple changes like getting morning light, taking outdoor midday breaks, sitting near windows, and keeping a consistent sleep schedule can help restore circadian rhythm and support glucose stability

Your cardiovascular risk score reflects how well blood flows through your smallest vessels, and those same vessels determine whether your retina and optic nerve stay healthy as you age
People with higher heart risk scores face a much greater chance of developing serious eye diseases years before vision problems become noticeable
Eye damage builds quietly as vascular and metabolic stress accumulates, which explains why vision loss often appears before obvious heart symptoms
Improving cellular energy and blood vessel health protects your eyesight by restoring circulation to your retina and optic nerve rather than reacting after damage occurs
Using a heart risk score as an early vision warning gives you a practical way to act sooner, personalize prevention, and lower your risk of permanent vision loss

Heavy short-form video use trains your brain to favor speed and novelty, which weakens sustained focus and makes everyday tasks feel harder to finish
Attention loss linked to scrolling reflects learned brain adaptation, not a lack of intelligence, motivation, or discipline
Endless feeds strain self-control systems, raising stress and mental fatigue while leaving confidence and self-image largely unchanged
Younger users and frequent daily scrollers show the strongest effects, but attention strain appears across all ages and platforms
Focus improves when you remove constant reward loops and retrain your brain with uninterrupted work, movement and clear boundaries

The bowel prep used before a colonoscopy does more than empty your colon; it strips protective mucus, wipes out beneficial gut bacteria, and weakens your gut's natural defenses right when they are needed most
Research shows nearly half of people experience bloating, abdominal pain, or digestive distress for weeks after a colonoscopy, and these symptoms trace back to microbiome disruption rather than the procedure itself
If you already have gut inflammation, inflammatory gut conditions, or low bacterial diversity, bowel prep increases tissue damage, allows harmful bacteria to escape the gut, and raises the risk of prolonged flare-ups
Colonoscopy prep shifts the gut environment in favor of inflammatory bacteria by increasing oxygen exposure and reducing butyrate-producing microbes that keep the colon healthy and inflammation controlled
Simple choices, such as split-dose prep, carbon dioxide inflation, supportive nutrition, and avoiding inflammatory fats, help protect your gut and speed recovery if you decide to undergo a colonoscopy

A review by the U.S. Food and Drug Administration (FDA) identified 51 PFAS in 1,744 cosmetic products. Among the 25 most-used PFAS, 19 lacked sufficient safety data for assessment
The most common PFAS in European makeup were polytetrafluoroethylene (PTFE) in 26% of PFAS-positive products and perfluorodecalin in 22%, both used to soften skin
In a 2021 study, researchers discovered that 82% of waterproof mascaras and over 60% of tested lipsticks and foundations contained high levels of fluorine, indicating the presence of hidden PFAS
Several top brands like Urban Decay, Inglot, L'Oréal, Maybelline, Burt's Bees, and Bare Minerals have faced lawsuits or investigations for PFAS contamination despite being marketed as "natural" or "clean"
While the FDA lacks a national ban, U.S. states are now leading the shift toward PFAS-free beauty products — nine states have passed or scheduled bans on intentionally added PFAS in cosmetics through 2032
