Hypocretins: the timing of sleep and waking.

abstract：:Since 50-60% of the human body consists of water, the physiology of blood circulation might be affected by a full moon differently than during other days of the month. This study analyzed a potential association among lunar phases, seasonal variations, and the rate of spontaneous epistaxis. Consecutive admissions sole...
