Irregular heartbeat linked to working too many hours
It goes without saying that a job almost always results in a few late-night shifts. However, a new study has found that if you make a habit of being the last one out of the office, you may be putting your health at risk.
In a study of more than 85,000 adults in the U.K., Denmark, Sweden and Finland, researchers found that in a 10-year span, working more than 55 hours per week increased patients' risk for A-fib by 40 percent.

Officially known as atrial fibrillation, it's considered the most common type of an irregular heartbeat, which could lead to heart failure. The study found those working long 11-hour days increased the rate of incidents.

Right now, researchers aren't sure why exactly that is. Mika Kivimaki, a researcher at University College London and the lead author of the study, is ruling the results a correlation, not a causation.
And before you quit your job, Kivimaki says a healthy young person with few additional risk factors other than working long hours probably won't develop A-fib.
