Characteristic, synthesis, and non-photic regulation of endogenous melatonin

Several researchers have confirmed that the melatonin hormone is significant to the body’s circadian rhythm, hence, the need to explore the connection between the two aspects. The circadian rhythm is a natural endogenous process that controls essential body functions as it affects hormone release, body temperature, sleep patterns, and eating habits. In that view, the circadian rhythm relies on melatonin to synchronize the night and day cycles. Melatonin plays a significant role in controlling the circadian rhythm by facilitating quality sleep at night and alertness during the day. In effect, understanding the acute non-image-forming visual effects of melatonin will help derive ways to ensure the circadian rhythms operate efficiently for healthy body functions.
