That long afternoon nap you look forward to at the end of the working day might not be a good sign, especially if you’re a repeat offender of hitting the snooze button.
Researchers have found that those who nap for more than an hour a day have a 45% increased risk of having type 2 diabetes.
Experts from Japan looked at data from 21 studies concerning more than 300,000 people and found the association between daytime snoozes and type 2 diabetes.
But they found shorter naps didn’t show an increased risk and might even have beneficial effects on diabetes, but added: “Further studies are needed to confirm the efficacy of a short nap.”
The authors of the study – which is to be presented to the European Association for the Study of Diabetes (EASD) meeting in Munich – said the desire to nap can be the result of a busy social or work life, or even a sleep disorder.
Naveed Sattar, professor of metabolic medicine at the University of Glasgow, said of the study: “It’s likely that risk factors which lead to diabetes also cause napping. This could include slightly high sugar levels meaning napping may be an early warning sign of diabetes.”
