Women who spend many years working long hours have significantly higher chances of developing heart disease, cancer and other chronic diseases, according to new research. The study found that women who worked more than 60 hours per week were nearly three times more likely to develop heart disease, non-skin cancers, arthritis and diabetes than those who worked less. Researchers at the Center for HOPES at Ohio State University’s College of Public Health and the Center for the Science of Health Care Delivery at Mayo Clinic conducted the research. Even among women who worked fewer than 60 hours per week, the odds of developing the chronic ailments grew as women’s work hours increased, according to the study—a trend that did not hold true for men. Men who worked longer hours had an increased risk only of developing arthritis, and actually had a decreased risk of heart disease when they worked “moderately long hours” of 41 to 50 hours per week.
