Sleepdep doubles obesity risk
A researcher at Britain's Warwick Medical School has concluded that sleep-deprived children and adults are twice as likely to be obese as their well-rested counterparts.Professor Cappuccio points out that short sleep duration may lead to obesity through an increase of appetite via hormonal changes caused by the sleep deprivation. Lack of sleep produces Ghrelin which, among other effects, stimulates appetite and creates less leptin which, among other effects, suppresses appetite. However he says more research is needed to understand the mechanisms by which short sleep is linked to chronic conditions of affluent societies, such as obesity, diabetes and hypertension.Link (via Digg)
