Long naps link to diabetes
A STUDY presented at a recent scientific congress reported a link between long naps and a higher risk of diabetes, though it couldn’t say if daytime sleeping was a symptom or a cause.
People who slept more than an hour each day were 45% more likely to develop Type 2 diabetes.
Without treatment, the disease can lead to blindness, nerve damage, kidney failure, heart disease and premature death.
The meta-analysis – a review of existing scientific literature – by Yamada Tomahide of the University of Tokyo and colleagues, covered more than 300,000 people of Asian and European origin from around the world.
For naps of less than 40 minutes, the link with diabetes disappeared, they noted.
More experiments need to be carried out to reveal whether too much day-time sleeping is bad for health. – AFP-Relaxnews
