A new analysis links sleep duration to epigenetic aging, with a sweet spot that echoes ancestral patterns and the restorative biology first mapped by Kleitman.
Three things to remember
- Optimal sleep range: 6.4–7.8 hours per night.
- Both short and long sleep may accelerate epigenetic aging.
- Mechanism likely involves stress hormones and DNA repair.
