The hormone does the pineal gland release A. melatonin. Therefore , A. melatonin is correct .
Pineal Gland: The pineal gland is located deep within the brain, in the epithalamus region. It is a photosensitive organ, which means it can detect changes in light and darkness.
Melatonin Production: Melatonin production is closely tied to the perception of light. When the surroundings become dark, the pineal gland is stimulated to produce melatonin, which is released into the bloodstream.
Circadian Rhythms: Melatonin is a key player in the body's circadian rhythms, influencing the sleep-wake cycle, body temperature, and various hormonal fluctuations throughout the day and night.
Sleep Regulation: The pineal gland's release of melatonin helps promote drowsiness and prepares the body for sleep. This is why melatonin supplements are sometimes used to address sleep disorders or jet lag.
Other Functions: Beyond regulating sleep, melatonin also has antioxidant properties and is thought to play a role in immune system support and the regulation of reproductive hormones.
Light Exposure: The suppression of melatonin production during the day is primarily due to exposure to natural and artificial light. This is why it's often recommended to limit exposure to screens before bedtime to help maintain healthy sleep patterns.
