In a research review published in The Lancet involving more than 600,000 men and women, it was found that a 55-hour workweek led to a 33 percent increase in stroke plus a 13 percent risk of coronary heart disease.1 Another study found that working 49 hours a week was associated with poor mental health, especially in women. (The average person working full-time in the USA works 47 hours a week, and 4 out of 10 people work 50 or more hours per week.)2 These results are not surprising when you think about it.
