The Science of Sleep: Evidence-Based Strategies for Peak Recovery

Sleep is not merely rest. It is an active biological process where the brain consolidates memories, clears metabolic waste, and repairs tissue. Shortchanging it has measurable, compounding costs.

Sleep Architecture Matters

A complete sleep cycle — N1, N2, N3 deep sleep, and REM — takes approximately 90 minutes. Deep sleep dominates early in the night; REM dominates later. Both serve distinct, irreplaceable functions.

Circadian Rhythm Alignment

Morning light exposure within 30 minutes of waking is the single most powerful lever for setting your circadian rhythm. It advances your sleep timing, improves mood, and increases afternoon alertness.

The 10-3-2-1-0 Rule

No caffeine 10 hours before bed, no food 3 hours before, no work 2 hours before, no screens 1 hour before, and 0 snooze presses. Simple rules, dramatic results.
