Sleeping in the Afternoon May Lead in an Increased Risk of Diabetes

Sleeping in the afternoon and particularly after a heavy lunch is all too easy but people who feel excessively sleepy in the daytime and like to nap for an hour or longer are at increased risk from developing diabetes.

Sometimes we fall asleep in the afternoon, even when we shouldn’t such as at our office desk but even a relaxing nap on the sofa at home can create a greater risk of developing the medical condition diabetes according to a new medical study on sleep patterns carried out by researchers at the University of Japan.

Although recent research has implied that a daily nap could improve health and help people live longer, it seems that dozing for too long and particularly in the afternoon after lunch may actually by harmful.

Research scientists at the Tokyo University are uncertain if it is the napping itself or an underlying medical condition which makes people more sleepy, that is driving the increase diabetes effect.

Speaking on the subject, Dr Tomohide Yamada had this to say. “Entering deep slow-wave sleep and then failing to complete the normal sleep cycle can result in a phenomenon known as sleep inertia, in which a person feels groggy, disoriented, and even sleepier than before napping.”
Many tens of millions of Americans have diabetes and many also remain undiagnosed. Cases in England and Wales also have risen by 59.8 per cent in the past decade – and in America many millions of adults are now coping with the condition as compared to a decade ago.
Dr Yamada continued: “Several studies have demonstrated the beneficial effects of taking short naps less than 30 minutes in duration, which help to increase alertness and motor skills.
The new research on the effects of later day sleeping and the risk of developing diabetes was presented at the European Association for the Study of Diabetes annual conference in Stockholm.
