Sleep architecture: the most underrated longevity intervention
Hours in bed are a poor proxy for restoration. What matters is the shape of the night — and it is remarkably modifiable.
Deep sleep clears metabolic waste from the brain and drives the overnight growth hormone pulse. REM consolidates memory and regulates mood. Two people can both log seven hours and have entirely different nights.
What we look at
Sleep latency and fragmentation across a two-week window
Overnight heart-rate variability and resting heart rate trend
Timing consistency — the single strongest lever for most patients
Evening light, alcohol and late training load
Fixing timing consistency alone moves recovery metrics for the majority of people we see. It costs nothing and compounds quickly, which is why it comes before supplementation in every protocol we write.
