Sleep is an essential time for the brain to recharge its batteries, sorting and structuring the wealth of information received during the day. It allows us to evacuate accumulated fatigue, both physical and mental. It can also provide a break from our current thoughts and preoccupations. Although these recur throughout the day, we're better equipped to deal with them once we're rested, because sleep plays a major role in our efficiency, mood and well-being.
