Taking long afternoon naps may increase risk of diabetes

Napping for more than an hour in the daytime may raise the risk of Type 2 diabetes by 45 per cent a new, study shows.

Researchers at the University of Tokyo used data from 21 studies involving more than 300,000 people who had recorded their daily level of napping.

They found that after 60 minutes napping appears to become harmful with the risk increasing the more time a person is asleep. However there was no risk before one hour.

But the study didn’t show cause and effect, so the researchers can’t say for sure whether the long naps was actually responsible for the increased risk of those conditions.
