Question

Quizplus · Accepted Answer

Melatonin is a hormone that plays a crucial role in regulating our internal biological clock, which is responsible for our daily sleep-wake cycles. When the levels of melatonin in the body rise in the evening, it signals to the brain that it's time to sleep. Conversely, when melatonin levels drop in the morning, it signals that it's time to be awake. Therefore, melatonin is primarily associated with daily biological rhythms and sleep. While it can also be affected by drug use and puberty, these are not the primary functions of melatonin.
