Detailed explanation-1: -The main function of your pineal gland is to receive information about the daily light-dark (day-night) cycle from the retinas in your eyes and then produce and release (secrete) melatonin accordingly-elevated levels at night (during dark hours) and low levels during the day (during light hours).
Detailed explanation-2: -Your pineal gland secretes the highest levels of melatonin during the night and minimal amounts during the day.
Detailed explanation-3: -Melatonin is a hormone that your brain produces in response to darkness. It helps with the timing of your circadian rhythms (24-hour internal clock) and with sleep. Being exposed to light at night can block melatonin production.
Detailed explanation-4: -The pineal gland is a small gland in the center of the brain. It secretes the hormone melatonin and is primarily responsible for regulating patterns of sleep and waking.
