😴 Tag the person who trains six days a week and sleeps five hours.
Adolescent athletes sleeping under 8 hours a night were roughly 1.7 times more likely to sustain an injury. One week of 5 hour nights was enough to drop daytime testosterone by 10 to 15% in healthy young men. Sleep extension improved sprint times and shooting accuracy in basketball players.
Training is only the stimulus.
The adaptation is built while you sleep. Growth hormone
pulses in slow wave sleep, muscle protein synthesis runs through the overnight fast, and skill consolidates in REM.
Sleep restriction also lowers your pain threshold and raises perceived exertion, which means the same program feels harder and hurts more. If you are in persistent pain and sleeping badly, that is not a coincidence.
Five things that actually work 👇
1. Fixed wake time, seven days a week
2. Daylightwithin 30 minutes of waking
3. Caffeine cut 8 to 10 hours before bed
4. Cool, dark, boring room
5. Alcohol out of the last few hours
Before you add another supplement or change your program, fix the 7 to 9 hours.
