Josiane Broussard, PhD, is scientist at the University of Colorado, Boulder, and especially is dealing with sciences concerning sleep disturbances resp. –restrictions connected with diabetes and related topics like insulin resistance and insulin sensitivity. A disturbed insulin sensitivity is a risk factor for diabetes type II. The online edition of Reuters recently published an article with the latest findings of a study.
In this study, the scientist and her team proved, that lack of sleep increases the risk of diabetes. During the duration of the study, the participating 19 young, healthy men received a low-calorie diet. The experiment was divided into two parts: in one part, the men slept 8.5 hours, in the other part the men were deprived of sleep on four consecutive nights, the two following nights they received an extra dose of sleep.
After the four nights of sleep deprivation, the insulin sensitivity decreased by 23 % and the body produced additional insulin. Insulin sensitivity as well as insulin content normalized after the two nights of extra sleep to the values seen during the first part of the study.
“We don’t know, whether the human being is able to permanently compensate the effects of a frequent lack of sleep by an extra portion of sleep”, Broussard is warning. “Also, the findings of the study don’t mean that catching up on lack of sleep is preventing from diabetes. But, it is very likely that additional sleep is beneficial for every human being who is suffering under lack of sleep.”
Even if it is not clear, whether the findings can simply be transferred on elder people who are suffering under overweight, the influence of sleep on our health is clearly visible. Out of this reason it is best, to support health every night by healthy and restful sleep!
