Detailed explanation-1: -Melatonin is the only known hormone synthesized by the pineal gland and is released in response to darkness hence the name, “hormone of darkness” [10]. Melatonin provides a circadian and seasonal signal to the organisms in vertebrates.
Detailed explanation-2: -Which of the following is true of melatonin? It is a sleep hormone released by the pineal gland into the bloodstream.
Detailed explanation-3: -Melatonin’s effect on sleep The longer the night, the longer your pineal gland secretes melatonin. Because of this, melatonin has often been referred to as a “sleep hormone.” While melatonin isn’t essential for sleeping, you sleep better when you have the highest levels of melatonin in your body.
Detailed explanation-4: -It’s a part of your endocrine system and secretes the hormone melatonin. Your pineal gland’s main job is to help control the circadian cycle of sleep and wakefulness by secreting melatonin.
Detailed explanation-5: -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.
