“Go to bed on time” is a recurring signal
Johnson repeatedly frames sleep timing as a key protocol behavior. Keep it as his source-backed habit signal rather than a universal prescription.
// PROTOCOLS / sleep
Sleep protocol
Sleep coverage uses tweet-backed and protocol-backed material: bedtime consistency, sleep front-loading, wearable/biological-age framing, and source-aware caveats around exact metrics.
Source-aware summary only; not medical advice. Sleep score, REM, HRV, and wake-event values stay out until source verified.
Earlier sleep before a planned late night
The May 24 tweet supplies a current example of sleep front-loading before violating an 8pm bedtime rule.
Do not publish exact REM/HRV targets without source verification
Prototype numbers like sleep score, REM percentage, HRV, or wake events need source-backed confirmation before they become public metrics.
