Numerous studies have produced findings that point to alarming correlations between working long hours and health problems, according to The Washington Post.
Here are four things to know about the risks of working lengthy hours.
1. A Gallup study last year found the average American works 47 hours per week.
2. Those who work more than 55 hours a week have a 33 percent higher risk of stroke than those working 35 to 40 hours each week, and a 13 percent increased risk of coronary heart disease, according to a study published in the British journal The Lancet.
3. Other studies have linked long workweeks to increased risks of depression, Type 2 diabetes and sleep disturbances.
4. Working long hours also affects cognitive function. A study from Stanford found productivity decreases at around 50 hours a week and plummets at 55 hours a week. No difference in output was found between those who worked 70 versus 56 hours a week.
