Melatonin helps control our "circadian rhythm"...sleep/wake cycles.
Imbalance of melatonin is believed to be the main cause of seasonal affective disorder...and other symptoms of depression.
Melatonin: produced in darkness and may cause feelings of darkness; hence the moniker, "Hormone of Darkness".
