Melatonin and Sleep

Melatonin, secreted by the pineal gland, plays a crucial role in signaling the body that it's time to sleep, typically around 9 or 10 PM. The relationship between melatonin and the sleep-wake cycle is intricately linked to the body's circadian clock, regulated by the super chiasmatic nucleus. Understanding this complex system sheds light on how various proteins and genes work together to maintain our internal timing.
