Effects of Melatonin on Diurnal Mood.
Abstract
As a substance produced nocturnally by the pineal gland, melatonin may have utility in promoting sleep during diurnal or other unusual sleep periods. Oral doses (100 mg and 10 mg) of melatonin were used to evaluate effects on diurnal mood and oral temperature. The six subjects in the experiment were male volunteers (range 20-42 years old). Oral temperature, plasma and salivary melatonin samples were obtained every 2 hours beginning at 0800 until 1700. A significant correlation (r =0.74) occurred between plasma and salivary melatonin samples. Temperature effects, subjective fatigue and confusion scores were increased by the 100 mg dose within 3-4 hours after dosing. Salivary levels of melatonin may be used as a non-invasive measure of plasma melatonin. As a substance produced endogenously, melatonin may make useful non-addictive soporific devoid of typical sedative side effects.
