Melatonin â A signal of darkness and marker for circadian rhythms. Melatonin is a naturally occurring hormone that is key to sleep and the sleep-wake cycle in humans and animals. In the body, melatonin is produced by the pineal gland in the brain when night falls.
Low levels of melatonin at night can cause insomnia, and as a result, taking melatonin can help people to sleep better. However, melatonin has other roles besides helping us to get a good nightâs sleep. Melatonin is also a powerful antioxidant, and so it is important for the health of the immune system.elatonin is a hormone which is secreted by the pineal gland. Its primary function is to help regulate the bodyâs circadian rhythm. Iâve discussed the circadian rhythm in the past with the hormone cortisol, as this hormone should be at the highest levels when we first wake up, and at the lowest levels at night.
