A Gallup poll reports that adults employed full time in the United States works an average of 47 hours per week. A team from Seoul National University (Korea) completed a suidy involving 8,350 adults enrolled in the Korean National Health and Nutrition Examination Survey IV. Data analysis revealed that working more than 40-hours a week may increase a person’s risk of developing coronary heart disease – a condition in which the blood vessels that supply blood and oxygen to the heart narrow dramatically. The team reports that people who work 61 to 70 hours are at a 42% increased likelihood of developing coronary heart disease; those working 71 to 80 hours at 63% increased risk; and people putting 80-plus hours in at work are at 94% increased risk. The study authors warn that: “Long working hours are significantly related to risk of coronary heart disease.”
