What ages you
Smoking and Biological Age — Why Cigarettes Age You
Smoking ages your blood vessels, skin and lungs at once, making it a leading reason biological age runs above real age. The upside: quitting shows recovery relatively quickly.
Exercise and Biological Age — The Strongest Youth Habit
Exercise keeps your heart, muscles, metabolism and brain young at once — one of the biggest levers for a lower biological age.
Sleep and Biological Age — Why Good Sleep Is Anti-Aging
Sleep is when the body repairs and resets. Chronic shortage or irregularity speeds metabolic, immune and brain aging.
Vegetables, Fruit and Biological Age
The fiber and antioxidants in vegetables and fruit lower inflammation and oxidative stress, helping keep biological age younger.
Alcohol and Biological Age
Alcohol lowers sleep quality and burdens the liver and metabolism; the more often you drink, the more it pushes biological age up.
Stress and Biological Age
Ongoing stress raises cortisol, worsening inflammation, blood pressure and sleep, and over time pushes biological age up.
