Sleep Duration & Longevity
Does sleep duration affect how long you live?
Both too little and too much sleep are linked with higher mortality, while 7–9 hours supports optimal longevity.
Explanation
Large population studies show a U-shaped relationship between sleep and mortality. Insufficient sleep impairs glucose metabolism, raises blood pressure, and accelerates neurodegeneration.
Practical Emphasis
Aim for 7–9 hours of restorative sleep most nights. Track sleep with wearables.
Action Tip
Target 7–9 hours of nightly sleep for maximum health benefit.
