Sleep Deprivation Linked to Increased Hunger and Obesity
Sleep deprivation alters hormones and increases appetite, according to the results of a brief randomized study published in the December 7 issue of the Annals of Internal Medicine.
The National Institutes of Health, the University of Chicago, the European Sleep Research Society, and the Belgian Fonde de la Recherche Scientifique Medicale supported this study, which monitored 12 healthy male volunteers who were sleep-deprived for two days.
The authors found that "Short sleep duration in young, healthy men is associated with decreased leptin levels, increased ghrelin levels, and increased hunger and appetite." The authors suggest, "Additional studies should examine the possible role of chronic sleep curtailment as a previously unrecognized risk factor for obesity." Source: Medscape Medical News.
