Sleep 101: the free performance edge

Sleep is the most underrated sports performance drug.

Studies on college and pro athletes consistently show: bump sleep from 6 hours to 9 hours → 10-15% improvement in speed, accuracy, and reaction time. Almost no other intervention comes close.

How much you actually need

• Teen athletes: 9-10 hours
• Adults: 7-8 hours
• Game night after: may need an extra hour to recover muscle damage

The 7 sleep rules that move the needle

1. Consistent bedtime — same time every night, even weekends. The biggest lever.

2. No phones in the bedroom — or phone on Do Not Disturb in the hallway

3. Cool room — ~65 F / 18 C

4. Blackout shades — light kills deep sleep

5. No caffeine after 2 pm — half-life is 5-6 hours; it's still working at bedtime

6. No big meals within 2 hours of bed

7. Morning sunlight within 1 hour of waking — sets your circadian clock for tonight

How to track sleep

If you have a wearable (Garmin, WHOOP, Apple Watch), look at deep sleep + REM. Rising trend = good; falling trend = something's off.

If no wearable, just track bedtime and wake time in a notes app for 2 weeks — patterns emerge fast.
