Working Long Hours May Increase Risk of Coronary Heart Disease

Working more than a 40-hour week has been linked to stress, dissatisfaction, and compromised health, and now new research on 8,350 Korean adults finds that it may also increase one’s risk of developing coronary heart disease, or narrowing of the blood vessels that supply blood and oxygen to the heart.

“The longer hours employees worked, the higher their chances of developing coronary heart disease within 10 years, with those working 61 to 70 hours having a 42% increased likelihood of developing the disease, those working 71 to 80 hours having a 63% increased likelihood, and those working more than 80 hours having a 94% increased likelihood,” said Dr. Yun-Chul Hong, senior author of the American Journal of Industrial Medicine study.
