Detailed explanation-2: -Then the SCN triggers the release of cortisol and other hormones to help you wake up. But when darkness comes at night, the SCN sends messages to the pineal gland. This gland triggers the release of the chemical melatonin. Melatonin makes you feel sleepy and ready for bed.

Detailed explanation-3: -Melatonin is a hormone that your brain produces in response to darkness. It helps with the timing of your circadian rhythms (24-hour internal clock) and with sleep. Being exposed to light at night can block melatonin production. Research suggests that melatonin plays other important roles in the body beyond sleep.

Detailed explanation-4: -Melatonin is a hormone produced by the pineal gland that’s associated with the body’s sleep-wake cycle. It helps regulate the body’s circadian rhythm, so you can fall-and stay-asleep. Disrupted or poor sleep can have impacts on melatonin and its role in promoting sleep in the brain.
