Sleep 7-9 Hours Consistently
Chronic sleep deprivation increases mortality risk by 12%. It's not about one bad night — it's about the pattern. Your body repairs itself during deep sleep, and cutting that process short accelerates aging at the cellular level.
Move Your Body Every Day
You don't need to run marathons. Thirty minutes of moderate activity — walking, cycling, swimming — five times a week reduces all-cause mortality by roughly 30%. The biggest gains come from going from sedentary to slightly active.
Maintain Strong Social Connections
People with strong social ties live an average of 7.5 years longer than those who are isolated. It's not about the number of friends — it's about the depth of connection. One or two close relationships matter more than a hundred acquaintances.
Manage Stress Before It Manages You
Chronic stress elevates cortisol, which damages nearly every system in your body over time. Meditation, therapy, exercise, and even just spending time in nature measurably reduce cortisol and extend healthspan.
Eat Real Food, Mostly Plants
The longest-lived populations on earth share one dietary pattern: mostly whole foods, mostly plants, moderate portions. You don't need a perfect diet — you need a consistently decent one.
Don't Smoke. Period.
Smoking is still the single largest preventable cause of death. Quitting at any age provides immediate benefits — within a year, heart disease risk drops by half.
Limit Alcohol to Moderate Levels
Recent research suggests even moderate drinking has more downsides than previously thought. If you drink, keeping it to a few drinks per week rather than per day makes a significant difference in long-term health outcomes.
