Yeah this is really interesting to me. I work out 4+ times per week, and I've noticed that when I go at it harder than usual, my body basically forces me to sleep twice per day until it's repaired itself, and when I sleep it's usually unintentionally 4-5 hours at a time. I'll wake up and can't go back to sleep, so I get up and do things for a few hours until it's time to sleep for another 4-5 hours. But when I take it easy with my workouts, I'll sleep a solid 7-9 hours uninterrupted. I wonder if my body does this because it needs nutrition and bloodflow to heal and doesn't want to wait for it.
