Daytime melatonin administration in elderly good and poor sleepers: Effects on core body temperature and sleep latency

Melatonin has been shown to have hypnotic and hypothermic effects in young adults and has been proposed as treatment for insomnia. However, the hypnotic and thermoregularory effects of melatonin remain to be simultaneously investigated for aged good and poor sleeers. The aim of this study was to explore the short-term effects of exogenous oral daytime melatonin on core body temperature, sleep latency, and subjective vigor and affect in aged women.
