Melatonin is a natural hormone that is secreted by the pineal gland in our brain that induces sleep. Darkness prompts the pineal gland to start producing melatonin while light causes it to stop the production. As a result, it helps regulate our body’s circadian rhythm and synchronize our sleep-wake cycle with night and day. In doing so, it promotes consistent, quality rest.Melatonin can be produced synthetically and is often consumed as a dietary supplement by those who have inconsistent sleep-wake up cycles.
