Bryan Johnson's sleep protocol is built on the principle that sleep is the highest-leverage intervention for longevity and performance. He spends significant resources optimizing every variable that affects sleep quality, achieving documented 100% sleep scores on Whoop. The protocol is systematic, data-driven, and treats sleep as non-negotiable.
Step-by-Step Protocol
Morning Light Exposure
Within 30 min of wakingGet bright light exposure within 30 minutes of waking. Ideally direct sunlight for 10-30 minutes. This sets your circadian clock and builds proper sleep pressure for night.
Caffeine Cutoff
Before 9amNo caffeine after early morning. Bryan typically has his last caffeine before 9am. Caffeine has a half-life of 5-6 hours and quarter-life of 10-12 hours.
Last Meal Timing
3-4+ hours before bedFinish eating by 11am (Bryan's schedule) or at minimum 3-4 hours before bed. Eating close to bedtime raises core temperature and disrupts sleep architecture.
Evening Light Blocking
2-3 hours before bedBegin dimming lights and avoiding screens 2-3 hours before bed. Use red/orange lighting only. Wear blue-blocking glasses if screens are necessary.
Room Temperature
Throughout nightSet bedroom to 65-68°F (18-20°C). Use Eight Sleep or similar bed cooling if available. Your core temperature must drop 2-3°F to initiate sleep.
Complete Darkness
Throughout nightMake bedroom completely dark. Use blackout curtains, cover all LED lights, remove any light sources. Even small amounts of light impair melatonin production.
Sleep Supplements
30-60 min before bedTake magnesium glycinate, glycine, and low-dose melatonin before bed. These support natural sleep processes without dependency.
Consistent Sleep Time
Same time nightlyGo to bed at the same time every night. Bryan sleeps around 8:30pm. Consistency is crucial for circadian rhythm optimization.
Consistent Wake Time
Same time dailyWake at the same time every day, including weekends. No snoozing. Immediately get light exposure to reinforce circadian rhythm.
No Alcohol
AlwaysZero alcohol. Even one drink significantly impairs deep sleep, REM sleep, and HRV. There is no 'safe' amount for sleep optimization.
The Science Behind It
The protocol targets the two-process model of sleep: Process S (sleep pressure) and Process C (circadian rhythm). Morning light exposure and caffeine timing optimize Process S. Evening light blocking and consistent timing optimize Process C. Temperature manipulation leverages the body's natural thermoregulation for sleep onset. The supplements support natural neurotransmitter and hormone production without disrupting sleep architecture.
Expected Results
Common Mistakes to Avoid
- Thinking occasional alcohol won't matter (it always does)
- Not being strict enough about light in the evening
- Eating too close to bedtime
- Inconsistent sleep times on weekends
- Keeping bedroom too warm
- Taking too much melatonin (more is not better)
