Wellness & Prevention
The best medicine is prevention. Our wellness guides translate the latest research on nutrition, exercise, sleep, stress, and lifestyle into practical, evidence-based strategies you can actually use.
The evidence-based pillars
What actually works for long-term health
Decades of research converge on the same core pillars. Here is what the evidence says — without the hype.
Physical Activity
150 minutes per week of moderate aerobic exercise reduces cardiovascular events by 35%, cancer risk by 13%, and depression risk by 26%. Any amount is better than none.
Nutrition
The Mediterranean diet has the most robust evidence for longevity and cardiovascular protection. Ultra-processed foods are independently associated with higher all-cause mortality.
Sleep
Sleep is when the brain clears metabolic waste, consolidates memory, and regulates hormones. Chronic sleep deprivation raises diabetes risk by 37% and depression risk by 300%.
Stress Management
Chronic psychological stress promotes systemic inflammation and accelerates atherosclerosis. Mindfulness-Based Stress Reduction (MBSR) shows measurable reductions in BP and inflammatory markers.
Tobacco Cessation
Quitting at any age reduces risk dramatically. Combination nicotine replacement therapy plus varenicline produces the highest quit rates. Lung cancer risk approaches non-smokers within 10 years.
Preventive Screening
Regular blood pressure, cholesterol, glucose, and cancer screening catch disease early when treatment is most effective. Screening targets in the AHA's Life's Essential 8 framework.
