Detailed explanation-1: -Your pineal gland’s main job is to help control the circadian cycle of sleep and wakefulness by secreting melatonin.
Detailed explanation-2: -Pineal melatonin is a hormone that regulates the body’s daily (circadian) clock and so melatonin is commonly used in human research to understand the body’s biological time. There is a rhythm to the biology of the pineal gland and melatonin is secreted according to the amount of day light a person is exposed to.
Detailed explanation-3: -Since reduction in the amount of REM sleep is associated with cerebral maturation and since the pineal gland has been implicated both in cerebral development and in the organization of REM sleep, the pineal gland may be involved in the maturation of the adult REM sleep pattern.
