As anyone who has ever lain awake in the dark hours after going to bed will attest, sleep is complicated and a lack of it can be disruptive to every aspect of one’s life. Deep sleep is important for a number of brain functions, and essential in clearing the brain of toxic proteins such as beta-amyloid, which can accumulate in the brain over the course of the day. Beta-amyloid proteins contribute to the plaques that form in the brain in disorders such as Alzheimer’s disease.
