Long working hours leads to arrhythmia – scientists

Длинный рабочий день ведет к аритмии – ученые

Many of us work more than 55 hours per week

The lifestyle of those who recycles, in General, less healthy than others.

According to a recent study, the working week longer than 55 hours can cause the development of atrial fibrillation, one of the most common types of cardiac arrhythmias, which can lead to stroke. The study is published in the European Heart journal.

A study conducted by an international team of scientists led by Mika Kivimaki from University College London. Researchers analyzed the health of almost 85 thousand employees (the average age of participants was 43.4 years). None of them suffered from arrhythmia in the beginning of the experiment.

The authors investigated the data of electrocardiograms, medical history, information on drug costs and death certificates. Participants on average were followed for ten years.

Scientists have registered a little more than a thousand cases of atrial fibrillation.

Taking into account such factors as gender, social and economic status, it turned out that those who worked more than 55 hours a week (about 5% of the total number of participants) had the risk of arrhythmia almost one and a half times more than those who worked 35-40 hours per week (about 63% of all participants).

In nine cases out of ten, atrial fibrillation developed in those who before the study had never suffered from any cardiovascular diseases. Hence, scientists have concluded that long working hours can contribute to the development of this disease.

As noticed by the researchers, the lifestyle of those who recycles, in General, less healthy than others. They are less physically active, more likely to suffer from obesity and alcohol abuse.

Scientists say that stress at work is a potential risk factor for cardiovascular disease, and regular treatment may increase the risk of stroke. However, on the specific context, the duration of the working day with the development of atrial fibrillation, scientists know little.

We will remind, the founder of Internet company Alibaba Group Jack MA predicted humanity 4-hour working day for thirty years.
