According to the findings of a new study, published in the European Heart Journal, people who work more than 55 hours are at greater risk of developing serious heart issues. The researchers say that long working hours may increase the risk by 40%.
A study tracked more than 85,500 British and Scandinavian people and discovered that those who worked long hours were far more likely to develop atrial fibrillation over the next decade.
Study leader Professor Mika Kivimaki, of University College of London, says: “Those who worked long hours had a 1.4 times higher risk of developing atrial fibrillation, even after we had adjusted for factors that could affect the risk, such as age, sex, socioeconomic status, obesity, leisure time physical activity, smoking and risky alcohol use. Nine out of 10 of the atrial fibrillation cases occurred in people who were free of pre-existing or concurrent cardiovascular disease.”
