A study released Monday in the Journal of American Heart Association found that working 10 hours or more a day, just 50 days per year, can increase stroke risk by nearly a third (29%). That’s as easy as working 8 a.m. to 6 p.m about once a week. And working 10 hours or more a day, 50 days per year, for a decade, can increase your risk of having a stroke up to 45%.
For the study, researchers reviewed analyzed data on the working hours of more than 143,500 people in France since 2012. Of those analyzed, 29% reported working more than 10 hours a day for more than 50 days out of the year and 10% reported working that amount for 10 years or more. (Researchers say they excluded subjects who had a stroke within five years of their first reported work exposure and participants needed to have at least six months of work experience to be included.)
