Diabetes Linked To Insomnia
By Mike Boyle

A small study in the Journal of Clinical Endocrinology and Metabolism says that even a single of night of sleep deprivation can cause the body to show signs of insulin resistance, a warning sign of diabetes.

For this study, researchers examined nine patients, first after the patients had slept a full eight hours and then again after they`d slept just four. The scientists say that insulin sensitivity was reduced by as much as 25 percent when the patients were sleep deprived.

"Our data indicate that insulin sensitivity is not fixed in healthy [people], but depends on the duration of sleep in the preceding night," researcher Esther Donga wrote in the study, reports CBS News. "In fact it is tempting to speculate that the negative effects of multiple nights of shortened sleep on glucose tolerance can be reproduced, at least in part, by just one sleepless night."

A study by U.S. scientists published last year found that people who slept less than six hours a night were 4.5 times more likely to develop abnormal blood sugar readings in six years compared with those who slept longer.
