Bryan Johnson wakes at 5:00 AM. Not because he has to. Because he built his entire day around that choice. Set a real wake time and work backwards.
Set your alarm. Get up immediately. No snooze — every snooze disrupts your cortisol awakening response.
Go outside within 30 minutes of waking. Minimum 10 minutes of direct natural light. This sets your circadian clock for the entire day.
Bryan Johnson typically eats his first meal 30–60 minutes after waking. Start with protein and healthy fats — no refined carbs first thing.
Eat your largest, most complete meal here. Insulin sensitivity and gut motility are optimal 2 hours after waking.
Finish eating by this time. Bryan Johnson targets a 6–8 hour eating window. After this, only water and herbal tea.
Caffeine has a 6-hour half-life. Coffee consumed after this time will measurably reduce your deep sleep stages, even if you fall asleep normally.
Switch to warm, dim lighting. Avoid all screens or use blue-light blocking glasses. Blue light suppresses melatonin production for up to 3 hours.
Bryan Johnson's target bedtime is 8:30PM. This is when he aims to be in bed, eyes closed, ready to sleep — not scrolling.
Every minute past this time reduces your sleep window below 8 hours. This is not negotiable if you are serious about recovery.
Room temperature 65–68°F (18–20°C)
Core body temperature must drop to initiate and maintain deep sleep. A warm room is one of the most common causes of poor sleep quality.
Complete darkness — blackout curtains or eye mask
Even small amounts of light through closed eyelids activate light-sensitive cells in the retina and suppress melatonin.
Phone in another room — or at least face down, silent
The anticipation of notifications activates vigilance circuits in the brain that prevent deep sleep, even if the phone never rings.
No heavy exercise within 3 hours of sleep
High-intensity exercise raises core body temperature and cortisol. Both delay sleep onset and reduce slow-wave sleep quality.
Magnesium glycinate 400mg (if taking)
Magnesium activates GABA receptors and relaxes the nervous system. Bryan Johnson includes magnesium in his evening supplement stack.
Consistent wake time — even on weekends
Irregular sleep timing is more damaging to circadian rhythm than simply sleeping less. Your body clock cannot recalibrate if you reset it every weekend.
Bryan Johnson uses an Oura Ring and Eight Sleep pod to track sleep stages, HRV, and resting heart rate nightly. He adjusts behaviour the following day based on the data. You do not need the devices to implement the protocol — but you do need the discipline.
