All work and no play doesn't just make you dull, it could literally break your heart.
Emily Reynolds of Metro reports that a study published in the European Heart Journal has found that people who constantly work long hours are at far higher risk of heart disease than those who have regular working days.
Researchers tracked the condition of 85,000 subjects, both men and women, over a 10-year period. These research subjects had no pre-existing heart ailments.
The report notes that over 1,000 participants developed atrial fibrillation over the next 10 years. When sex, age, and socio-economic status were accounted for, the researchers saw that those working more than 55 hours a week were 1.4 times more likely to develop the condition.
Atrial fibrillation is a condition wherein a person has "an irregular and often abnormally fast heart rate." This could get considerably worse and lead to stroke or heart failure.
The heart condition is most probably a result of the fact that people who constantly log longer working hours tend to make poorer lifestyle choices, according to the study. In other words, they neglect to take care of themselves. Thus, they are more likely to experience depression, anxiety, obesity, and alcoholism.
