Caffeine Cutoff Protocol
Caffeine has a half-life of 5–6 hours. That means a 2pm coffee still has 50% of its caffeine in your blood at 8pm. This protocol structures your caffeine intake so it fuels your morning without wrecking your night. Simple rules, massive impact on sleep quality.
Method

Other Protocols
Cold Exposure Protocol
Structured daily cold water immersion for recovery, stress tolerance, and mental discipline. 2–5 minutes at 39–55°F. Consistent timing, consistent temperature. The discomfort is the point.
Wind-Down Protocol
A 90-minute pre-sleep sequence that systematically shuts down every stimulus keeping you awake. Light, temperature, screens, stimulation — each one gets addressed in order. This is how you fall asleep in under 10 minutes.
Morning Light Protocol
Get bright light in your eyes within 30 minutes of waking. This is the single most impactful thing you can do for circadian rhythm, energy, and sleep quality. Sunlight is best. Circadian lighting is the backup.
