Working Long Hours Linked To Greater Risk of Atrial Fibrillation

By jeremyc | July 17, 2017

A new study links working long hours with greater risk of atrial fibrillation, also known as irregular or quivering heart beat. In the study, involving about 85,000 adults, the researchers noted that the risk of developing atrial fibrillation in next ten years was about 40 percent greater in adults who worked 55 hours or more in a week, compared to those doing a normal working week (about 35-40 hours).

As atrial fibrillation is a big risk factor for stroke, this study might explain the findings of previous research in which scientists had found a link between working longer than normal hours and increased stroke risk.

To make matters worse, atrial fibrillation is associated with other severe health conditions as well, such as heart failure. It also might increase the risk of developing stroke-related dementia.

The finding of this study is like a warning sign to people who already carry a high risk of cardiovascular disease (such as people who smoke or lead a sedentary lifestyle or have excess body weight, hypertension, diabetes, prediabetes, and high cholesterol) and are also working many hours above the usual.

The study didn’t take into account job type and irregular working times (like night shift). Both of these factors might affect atrial fibrillation risk.
