Daytime Naps Of Over An Hour Raise Diabetes Risk

Napping for more than an hour during the day could be linked to 45% increased risk of type 2 diabetes. Researchers used data from 21 studies involving more than 300,000 people. They found that after 60 minutes napping becomes harmful, with risk increasing the more time a person is asleep. However, there was no link with naps of less than 40 minutes. Long naps could be a result of disturbed sleep at night, potentially caused by sleep apnea.

This sleep disorder could increase the risk of art attacks, stroke, cardiovascular problems and other metabolic disorder, including type-2 diabetes. Sleep deprivation, caused by work or social life patterns, could also lead to increased appetite which could raise the risk of type-2 diabetes. Although the mechanisms by which a short nap might decrease the risk of diabetes are still unclear, such duration dependent differences in the effects of sleep might partly explain this finding.
