Abstract

Sleep time decrease, caused by the demands and opportunities of modern society, has currently become a common habit. A relationship between sleep and food intake has been postulated by current literature. This fact is widely demonstrated in animal models that become hyperphagic after sleep deprivation. Shift work and time zones changes which normally affect the usual sleep pattern in humans are also associated with changes in food intake. Recent epidemiologic studies relate short duration of sleep time with increase in body mass index, due to the physiological changes in the release of the appetite-regulating hormones ghrelin and leptin. Current essay discusses the relationship between appetite regulating hormones and the increase in body mass index on sleep-deprived subjects.
