    Brief Introduction of Melatonin:

    Melatonin is a hormone naturally secreted by the pineal gland in the brain. Its main function is to regulate the circadian rhythm (biological clock) and help control the sleep-wake cycle.

    Basic Identity and Function:

    Sleep Hormone: Its main function is to send a signal to the body that "it's time to go to bed.

    Regulated by Light: Ambient light (especially blue light) significantly inhibits the secretion of melatonin. When it gets darker, the pineal gland begins to secrete melatonin, and the level of melatonin in the blood increases, making people feel sleepy and ready to fall asleep. When the light increases in the morning, the secretion decreases, helping people wake up.

    Regulate the Biological Clock: Help the body's internal clock synchronize with the light and dark cycle of the external environment.
