Yes, eating well, exercising, not smoking or drinking alcohol moderate lifespan, but according to the publication SLEEP Advances, the amount of shut-eye that we get at night might be more strongly linked to projected longevity than diet and exercise.

The researchers looked at a huge U.S. database of health survey data taken between 2019-2025, alongside life expectancies.
Insufficient sleep—less than seven hours of sleep a night—is “significantly negatively correlated with life expectancy.”
