Description
Melatonin is a hormone naturally secreted by the pineal gland, playing a crucial role in regulating the body's circadian rhythms and sleep-wake cycle. Its secretion increases at night and decreases during the day, earning it the labels "night hormone" or "sleep hormone." By coordinating with pineal gland activity, melatonin helps individuals fall asleep quickly, improve sleep quality, and regulate their biological clock. Beyond its role in sleep, melatonin possesses antioxidant properties, immune regulatory functions, and mood regulation benefits. Currently, melatonin is widely used to treat insomnia and other sleep disorders, as well as sleep issues caused by jet lag.
