Melatonin is a sleep hormone. The production and release of melatonin from the pineal gland occurs with a clear daily (circadian) rhythm, with peak levels occurring at night. It is secreted into the fluid around brain & spinal cord to convey signals to other organs located at different areas in your body. Tissues expressing proteins called receptors specific for melatonin are able to detect the peak in circulating melatonin at night and this signals to the body that it is night-time.
