More recently there was inter-departmental infighting between the Department of Health and the DTI about opting out of the EU Working Time regulations (which set a maximum of 48 hours). Health had commissioned research which clearly showed that working over 50 hours a week, especially for men, led to and increased risk of heart disease and stroke.
The latest news from University College, London, based on a study of over 500,000 workers from the US, Europe, and Australia, is that working more than 55 hours a week increases the risk of a heart attack by 13%.
Compared to people working a standard 40 hour week stroke risk increased by 10% if you worked up to 48 hours a week and by 27% if you worked up to 54 hours a week.
Working 55 hours or longer increased the stroke risk by a massive 33%.
Working long hours means you have less time to exercise or look after yourself, you probably eat fast food for the convenience and may drink more to help you relax.
Of course there are some extreme workers who appear to thrive on working long hours but how long can they keep it up?
