Melatonin is secreted by the pineal gland, a small, pea-shaped endocrine gland located in the brain. This gland synthesizes and releases melatonin in response to darkness, helping to regulate sleep-wake cycles and circadian rhythms. The production of melatonin is influenced by light exposure, with levels typically rising at night and falling during the day.
