Long hours at work can leave you feeling stressed and exhausted, but they may also be affecting your heart health. According to a new study, employees who work more than 55 hours per week may be at a greater risk of developing an irregular heartbeat, known as atrial fibrillation or A-fib.
In a study on nearly 85,500 middle-aged men and women from the UK, Denmark, and Sweden, researchers found that racking up more than 55 hours a week was associated with a 40 percent increased risk of getting A-fib over the following 10 years, compared to those who worked the standard 35 to 40 hour work week.
But before you worry that your work schedule may affect your heart, it’s important to note that a young, healthy person who works long hours has very little risk of developing A-fib. It’s more hazardous to those who already have a high risk of heart disease because of factors such as smoking, high blood pressure, or diabetes, he points out.
