Sleep contributes to physiological and psychological restoration. NREM sleep contributes to body tissue restoration. It allows the body to rest and conserve energy. This benefits the cardiac system by allowing the heart to beat fewer times each minute. During stage 4, the body releases growth hormone for renewal and repair of specialized cells such as the brain. During NREM sleep, biological functions slow. REM sleep is necessary for brain tissue restoration and cognitive restoration and is associated with a change in cerebral blood flow and increased cortical activity.
