New Delhi: Working more than 55 hours a week puts you at increased risk of developing serious heart problems, researchers have found.

 

The findings showed that, compared to people who worked a normal week of between 35-40 hours, those who worked 55 hours or more were approximately 40 per cent more likely to develop atrial fibrillation.

“A 40 per cent increased extra risk is an important hazard for people who already have a high overall risk of cardiovascular disease due to other risk factors such as older age, male sex, diabetes, high blood pressure, high cholesterol, overweight, smoking and physical inactivity or living with an established cardiovascular disease,” said Mika Kivimaki, Professor at the University College London.

“This could be one of the mechanisms that explain the previously observed increased risk of stroke among those working long hours. Atrial fibrillation is known to contribute to the development of stroke, but also other adverse health outcomes such as heart failure and stroke-related dementia,” Kivimaki added.

For the study, published in the European Heart Journal, the team analysed data from 85,494 men and women from the UK, Denmark, Sweden and Finland who took part in one of eight studies in these countries.
