Your Body's Repair Window Happens While You Sleep
Our Body Repairs While We Sleep — But Timing Matters
Growth hormone (GH) is released throughout the day, but the biggest surge happens in the first 90 minutes of sleep - during our deepest sleep phase. This is when our body does its heavy lifting: muscle repair, cell regeneration, bone strength and metabolism.
But when we go to sleep 1–2 hours later than usual, we don't get that full GH peak that night. Even if we sleep in the next morning to make up the hours - it doesn't recover it. Those extra morning hours are lighter sleep, not the deep sleep our body needed.
Regular sleep and wake times are just as important as how long one sleeps.
