Inadequate sleep can cause decreases in performance, concentration, reaction time and learning. It can also provoke memory lapses, behavior and mood problems. Sleep gives the body a chance to reproduce essential body substances and repair muscles, other tissues and damaged cells and it strengthens the immune system.

Brain glycogen levels are replenished during sleep.
