The Numbers Don't Lie
One bad night of sleep can cut next-day strength and reaction time measurably. Chronic short sleep (under 6 hours) is linked to lower testosterone, higher cortisol, worse glucose control, and slower muscle repair. You don't have a training problem — you might have a sleep problem.
How Much Do Lifters Need?
7-9 hours. Hard-training athletes often need the top of that range. If you're training 5-6 days a week on 6 hours a night, you're leaving gains on the table every single week.
The Wind-Down Protocol
- 90 minutes out: dim the lights, screens off or night mode. Your brain takes darkness as a melatonin cue.
- 60 minutes out: no heavy food, no intense training. Light stretching or a walk is fine.
- 30 minutes out: cool, dark room (65-68°F is the sweet spot), same bedtime every night — including weekends.
- Caffeine curfew: nothing after noon if you train in the evening. Caffeine's half-life is 5-6 hours.
What About Naps?
A 20-30 minute nap can rescue an off night without wrecking bedtime. Longer than that and you'll wake up groggy and push sleep later — net loss.
Track One Thing
For two weeks, note your bedtime, wake time, and next-day training quality (1-5). Most people find their best sessions follow their best sleep — and suddenly the 10pm bedtime stops feeling optional.
