Melatonin is an important hormone which is produced in our body during the night hours. It has many important functions as a signal to the internal biological clock in our brain, thereby allowing the adjustment of biological functions such as sleep, blood pressure and certain hormones with the night period. Melatonin production is inhibited by light and is diminished with advancing age and in some medical conditions.
