Part 03
Sleep
Your body's number-one repair tool. While you sleep, your body repairs itself.
Tissue repair
Muscles, tendons and joints rebuild themselves overnight.
Recovery hormones
Growth hormone, released in deep sleep, repairs your tissues.
Pain management
Sleeping well lowers your sensitivity to pain.
Alertness
Memory and focus get locked in. You stay alert.
Lack of sleep = more risk
When you're short on sleep
- Slower reaction time
- Reduced focus and judgment
- Pain feels stronger
- Incomplete muscle recovery
- More wrong moves and accidents
Fatigue drives like alcohol
Staying awake 17 to 19 hours straight hits your alertness as hard as a blood-alcohol level of 0.05.
