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.
A hormone produced by the pineal gland in darkness but not in bright light. Melatonin receptors in the brain react to this hormone and synchronize the body to the 24 hour day/night rhythm, thus informing the brain when it is day and when it is night.
