There are a lot of articles around about the causes of type-2 (late onset) diabetes.

Missing the obvious fact it’s almost always about the balance between diet and exercise, a variety of factors are adduced for this tiresome disease.

Did you know that both lack of and too much sleep can tip you over the edge? Either option can make you far more likely to develop diabetes, according to researchers at the Universite Laval in Quebec, Canada. The results are published in the journal, Sleep Medicine.

Optimum sleeping times are seven to eight hours a night, they say. If you undershoot or exceed that, you are two and a half times more likely to suffer blood sugar abnormalities.

Researcher Angelo Tremblay says, “The risk remains significant even after a statistical adjustment for body mass index and waist circumference. … It is clear the recommendation to seek an optimal sleep duration seems to be appropriate, but for some individuals it is easier to say than do.”

One factor that isn’t mentioned is the differences between individuals. Such research often assumes that everyone’s reaction to stress is identical. It isn’t.
