Bad night’s sleep raises risk of diabetes

Bad night's sleep raises risk of diabetesA bad night’s sleep may not just leave you tired and irritable. It could also raise your risk of diabetes, research suggests.

Just one night of tossing and turning and getting only four hours’ sleep can ‘profoundly’ affect the body’s ability to use insulin to convert sugar into energy.

Disruption of this delicate process can lead to diabetes.

Complications arising from the condition include heart disease, blindness and amputations.

With a soaring number of Britons developing diabetes – from 1.26million cases in 1996 to 2.35million today – the findings suggest sleepless nights caused by the stresses of modern life are at least partly to blame.

To make the link, Dutch scientists looked at how effective the bodies of nine healthy volunteers were at processing sugar. They were examined twice – once after a night of eight hours’ sleep and once after grabbing just four hours.

Halving the amount of sleep reduced the body’s ability to use insulin to process sugar – known as insulin sensitivity – by up to a quarter, the Journal of Clinical Endocrinology & Metabolism reports.

Previous research has found that several nights of poor sleep can send sugar levels haywire, but this study is the first to show that even one bad night – caused by a busy day at the office or a sick child – can be detrimental to health.



Randox Laboratories provide a number of tests used in the detection and screening of diabetes, including fructosamine, glucose and HbA1c.Ā  For more information, visit the Diagnostic Reagents section of the website.
