Napping during the day could be a sign of type 2 diabetes.

A new study by Japanese researchers, at the University of Tokyo, showed there was a link between daytime naps that lasted longer than 60 minutes and a 45 percent increased risk of type 2 diabetes. However, there was no link to naps with a duration of only 40 minutes.

They believe many factors could add to this condition. Sleep deprivation could lead to increased appetite and increase the risk of type 2 diabetes as well as people who are just unhealthy.

According to the research, there is now a lot of evidence that shows a link between sleep disturbances and diabetes.

Oddest things people do in their sleep

Sleep eating

Nocturnal sleep-related eating disorder is characterized by people sleep walking to their kitchens and eating. Often times, they have no recollection of it, and only realize when they discover messes and missing food.

Sometimes, the patient has severe weight gain and other health issues attributed to the disorder. 

Frequently, the foods eaten are high in fat, sugar and carbohydrates. Furthermore, people with the disorder create bizarre food combinations with the items they have access to in their kitchen. 

Acting out their dreams

REM sleep behavior disorder physically play out their dreams, moving their bodies or even getting out of bed.

Their dreams are so vivid and real, that during REM sleep, which normally restrains your muscles, your body still flails. 


It is possible to experience auditory, visual, tactile and olfactory hallucinations, as many times, the person cannot tell what is part of a dream and what is part of reality. 

The hallucinations often happen in the stages right before sleep (hypnogogic) or after sleep (hypnopompic). Hypnogogic can be associated with sleep paralysis and a fearful sensation. 

Hypnopompic is usually associated with dreams and 'feeling a presence in the room'. 

Sleep sex

Called 'sexsomnia', it falls under the category of parasomnia, the stage right before you fall asleep.

When a person has this disorder, they oftentimes engage in sexual acts with a partner or themselves, while asleep. They have no recollection of it. 

It is more common for people who normally are affected by other sleep disorders, or those taking sleep medications.

Sleep texting

Apparently, more and more people are sending texts in their sleep. 

"It is very common for people to do things in their sleep that they do repeatedly during the day," said a neurologist in an article to BBC. 

Understandably, the texts make little sense to the person after they've woken up. 

Exploding head syndrome 

It occurs when you're about to drift off into sleep, and suddenly a loud noise goes off in your head. 

Another parasomnia event, exploding head syndrome sounds similar to a clap of thunder or bomb. However, it sounds as if the noise could be heard by everyone, but in reality, it's internal.


A professor of metabolic medicine at the University of Glasgow said ""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."

Since this was an observational study, some believe it is not possible to make these conclusions about these findings.

So the next time you go to get some midday shut eye, be cognizant of your symptoms and sugar intake to steer clear of type 2 diabetes.
