Sleep Drives the Recovery Process
Recovery isn't just about resting specific muscle groups. It also means scoring 7-8 hours of restful sleep, because so much repairing and rebuilding happens when you're snoozing and your body isn't moving, says Ballantyne. "Sleep also leads to increases in the production of growth hormones, which aids recovery," he says. And of course, a sleep deficit hurts performance in other ways, such as altering metabolic functioning and plunging you into brain fog.
