Many employees dream of doing a nap after their lunch break, before resuming their work. Anti-fatigue, relaxing, stimulating and even good for the heart (because anti stress), the virtues of a nap no longer need to be demonstrated. On the other hand, it would seem that beyond a certain duration the nap can be counterproductive.
A Japanese study from the University of Tokyo warns fans of long naps: beyond an hour they would increase the risk of type 2 diabetes by 45% compared to those who do not take a nap.
The results of their work, which involved a panel of 300,000 people, were presented at the annual congress of the European Association for the Study of Diabetes (EASD) in Munich, Germany.
“This study does not prove for sure that the daytime nap causes diabetes, only that there is an association between the two which needs to be investigated in further research,” stressed the EASD echoed by the AFP.
The researchers observed in this meta-analysis of 21 studies that the risk of type 2 diabetes associated with naps longer than 60 minutes did not hold for 40-minute naps.
In other words, to be fresh and have an iron health, get some sleep during the day but not too much !
Fans of short naps less stressed?
For Dr. Joel Zonszei, director of the Clinical Diabetes Center at Montefiore Medical Center in New York, this association between diabetes and nap duration is interesting and lends itself to various interpretations. He reminds the Health site that type 2 diabetes is often favored by an unhealthy lifestyle such as poor eating habits, stress or a lack of physical exercise. Therefore, according to him, it could be that those who take short naps may be less stressed and allow themselves more free time than those who take long naps. A difference that could come into play is the fact that short naps are not linked to the risk of type 2 diabetes.
