Understanding Sleep

Sleep is a recurring state in which the body and mind are at rest, reducing muscle activity and interaction with surroundings. Sleep involves alternating cycles of REM and non-REM sleep, with each cycle averaging 90 minutes. The right balance between these cycles is key to waking up refreshed.
