Q

Slow wave sleep (SWS) is for body repair

A

Oswald suggests that in stage 3&4 there is an increase of growth hormone (GH) production which is used in protein synthesis. The fact that when rats are injured and don’t sleep, they heal slower supports the idea that body repair happens during sleep.
