Melatonin is an integral part in the body’s natural sleep cycle called the circadian rhythm, which controls not only the wake and sleep cycle, but other physiological functions such as blood pressure, digestion and brain-wave states as well. The primary stress hormone, cortisol, inhibits melatonin production and absorption, leading to restless sleep and insomnia. Therefore, melatonin supplements are often recommended because they may help support deep, natural sleep and a consistent circadian rhythm cycle.
