Worry: But getting enough kip can reverse trend

A lack of sleep can causes diabetes, a new study warned.

Having too few hours rest may disrupt fat metabolism and reduce the ability of insulin to regulate blood sugars.

But reversing this may be down to just getting a good night’s kip of around eight hours.

The study by the University of Chicago found a lack of sleep can elevate levels of free fatty acids in the blood, accompanied by temporary pre-diabetic conditions in healthy young men.

It was the first to examine the impact of sleep loss on 24-hour fatty acid levels in the blood.

Researchers found after three nights of getting only four hours of sleep, blood levels of fatty acids, which usually peak and then recede overnight, remained elevated from about 4am to 9am.

As long as fatty acid levels remained high, the ability of insulin to regulate blood sugars was reduced.
