Bryan Johnson’s Best Health Hack: Lower Your RHR Before Sleep = Sleep Better and Live Longer

Bryan Johnson’s longevity project is built around measuring biological age organ by organ, then testing interventions against those biomarkers. At 47, he says his left ear tests at 64 after childhood gunfire and loud music, illustrating why he treats aging as many separate systems rather than one number.

Johnson says his most useful health target is resting heart rate immediately before sleep. He recommends establishing a baseline, trying to lower it roughly 10%, and finishing the last meal four hours before bedtime so digestion does not keep heart rate elevated.

His sleep protocol is strikingly simple compared with his reputation for extreme longevity routines. Stop screens an hour before bed, avoid caffeine from around noon, use warmer evening lighting, and create a wind-down routine such as walking, reading, breathing or meditation.

Johnson argues that sleep is the foundation of self-control, mood and performance, not time stolen from ambition. He says poor sleep weakens willpower and rejects startup culture’s idea that founders must “martyr” themselves, telling one founder that prioritizing sleep should make him better at work and relationships.

He is trying to turn health into a measurable competition rather than a vague identity. Johnson publishes his biomarkers, claims they are among the world’s best, and invites others to compete, framing longevity as a quantifiable “sport” built around slowing or reversing biological aging.

“Don’t die” is no longer merely Johnson’s personal health slogan; he presents it as a future ideology for humanity. He predicts that superintelligence will change humanity’s ideas about reality and argues that preserving existence could eventually become a principle comparable in cultural weight to democracy, capitalism or major religions.
