The blueprint, line by line
For your blueprint
Sleep comes first: plan the day around your bedtime, like your most important appointment
Their own practice · His framing, not a tested method. What it protects is well backed: AASM and SRS expert consensus: adults need 7 hours or more a night Research
Costs: no money; dinners, evenings and travel get planned around sleep
Habit
In bed at the same time every night, a bedtime you pick yourself
Guideline · In 61,000 UK Biobank adults wearing trackers, the most regular sleepers had 20 to 48 % lower mortality than the least regular, and regularity predicted it better than duration. Observational, no trial Research
Costs: no money; an evening reminder helps. He goes to bed at 20:30, and says you don’t need to
Mixed evidence · Little research: a 2024 scoping review calls the evidence preliminary. In 793 students, eating within 3 hours of bed went with 1.6 times the odds of waking at night (cross-sectional). No trial has tested 4 hours Research
Costs: no money; for a 23:00 bedtime, done eating by 19:00. He eats his last meal around noon
Habit
Screens off an hour before bed; wind down with a book, a walk or breathing
Mixed evidence · A review of 42 studies in 16 to 25-year-olds links phone and computer use at night to later bedtimes and shorter, poorer sleep, but all are observational; nobody has tested a 60-minute cut-off Research
Costs: no money; a book, a walk, a bath or a call instead of the phone
Guideline · Expert consensus 2022: at least 250 lux at the eye by day, daylight preferred, to anchor the body clock. The 15 to 30 minute window is his rule of thumb, not a studied cut-off Research
Costs: a few minutes outside, no money; he is up before sunrise and uses a bright lamp instead
Number
Exercise 6 hours a week: strength, cardio, stretching and balance
Guideline · Above the WHO’s 150 to 300 minutes. In 116,000 US adults followed for 30 years (the study his page cites), most of the lower mortality came from meeting the minimum; going 2 to 4 times over it added only a few percent more. Observational Research
Costs: about an hour a day; he says 20 minutes a day is a fine start. Apple’s Exercise ring may not count all stretching and lifting
For your blueprint
Watch your heart rate in bed before sleep: what raises it (late food, screens, a fight, alcohol) costs sleep
Their own practice · His own method from his own wearable. A lower resting heart rate does track lower mortality (87 studies: 17 % more risk per 10 extra beats, observational), but no study shows the pre-bed number predicts sleep Research
Costs: a watch or ring; or count your pulse for 6 seconds and multiply by 10 (his tip)
For your blueprint
Name the evening you who breaks your plans; morning you makes the rules and evening you can’t change them
Their own practice · His own technique, never studied as such. Its nearest relative, deciding in advance with if-then plans, helped people reach goals in a 94-study meta-analysis (a medium-to-large effect) Research
Costs: no money; ten minutes to write down the rules and the excuses evening you uses
