Working long hours may be hard on your heart


People who work 10 hours or more a day have a higher risk of heart-related problems, according to a study published in the European Heart Journal.

The findings are from the Whitehall II study, which started in 1985 and recruited more than 10,000 British civil servants. The current analysis looks at the results from 4,262 men and 1,752 women, aged 39-61, who were followed until 2002-2004. Reuters reports:

In all, there were 369 cases of death due to heart disease, non-fatal heart attacks and angina among the London-based study group-and the risk of having an adverse event was 60 percent higher for those who worked three to four hours overtime.

Working an extra one to two hours beyond a normal seven-hour day was not associated with increased risk...

...The higher incidence of heart problems among those working overtime was independent of a range of other risk factors including smoking, being overweight or having high cholesterol.
