Chapter 7: Sleep Health

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.
