You'll probably want to turn down that offer of overtime the next time your boss asks you after reading this. 


That's because, according to researchers in Canada, long working hours can increase the risk of diabetes in women - but not men. 


Analysing medical records of 7,000 men and women aged between 35 and 74 over a 12-year period, they found that women who work 45+ hours a week are more likely to develop the disease in comparison to those who work <40. 



Interestingly, the risk decreased for men in similar situations. 


Explaining the reasoning behind this, Dr Mahée Gilbert-Ouimet told ABC News that it is probably down to the "difference in paid and unpaid hours for men and women." 


"Women tend to do twice as much unpaid work, like household chores and other family duties," he said, which may contribute to higher stress and, in turn, affect blood sugar levels. 


The findings were published in the journal BMJ Diabetes Research & Care. 


Diabetes is a serious condition which, if left untreated, can cause kidney damage, heart disease, eye damage and infections.
