Key Takeaways
7-8 hours of sleep = -30% all-cause mortality (Sabia study, n=7,959)
The glymphatic system clears amyloid only during deep sleep
Sleep below 6 hours: HRV drops by 15-20%
18°C - optimal room temperature for deep sleep
Biological age responds to improved sleep within 6-12 weeks
🤖 AI Scientist Scientific Summary
Sleep is the foundation of biological repair. During deep sleep, the glymphatic system clears amyloid-beta, growth hormone surges, and DNA is repaired. Chronic sleep deprivation is associated with accelerated epigenetic aging and significantly increased all-cause mortality.

Frequently Asked Questions
How much sleep is needed for Longevity?+

7-8 hours consistently, per all the evidence. Below 6 hours is linked to dementia, diabetes, obesity, and increased mortality.

What is HRV and why does it matter?+

HRV = Heart Rate Variability. A measure of sleep quality and nervous-system health. The Oura Ring measures HRV at night. High HRV = lower biological age.

What helps deep sleep?+

Magnesium Glycinate 400mg, L-Theanine 200mg, room temperature 18°, complete darkness, a consistent sleep schedule.
