Friday – Sleep as a Longevity Hack 

Sleep isn’t recovery — it is performance. It’s when the brain detoxifies, tissues repair, and hormones regulate. Chronic sleep restriction shortens lifespan and accelerates aging through inflammation and oxidative stress (Irwin, Nat Rev Immunol, 2019). 

Adults need 7–9 hours, but quality matters more than quantity. Prioritize consistent bedtimes, a cool dark room, no screens an hour before bed, and limited caffeine after noon. 
REM and deep sleep cycles are crucial for cellular repair and memory consolidation — both decline with poor habits. 

If you’re chasing longevity, start with better sleep. It’s the most underused supplement there is.
