Heart rhythm

Working long hours leads to a dangerous heart rhythm disorder

Overworking could lead to more than just a simple exhaustion – it could possibly raise the risk of a very common and possibly dangerous heart rhythm disorder, according to a new British research. The leader of the study says that the results show that overworking/working long hours is strongly related to a high risk of atrial fibrillation (AF or A-fib), the most common cardiac arrhythmia. This is a well-known risk factor for a stroke. Some other cardiologists, namely from the USA, are saying that the study couldn't actually prove cause-and-effect, so the results need to be taken with a grain of salt. However, the evidence is still added to the ongoing theme that one's lifestyle and working patterns play a vital role in causing atrial fibrillation.

For every 1,000 people in the study, an extra 5.2 cases of A-fib were documented among those who work long hours during the last 10 years. This is a serious cause for concern, because A-fib is known to cause the development of stroke, along with some other serious health complications, the likes of congestive heart failure and stroke-related dementia. It's not all that bleak, because the scientists believe there are ways of minimalizing these risks. The who overwork should focus on losing weight, controlling their blood pressure and quitting smoking. Along with stress reduction this could prevent atrial fibrillation, and the person will end up reaping the benefits of a healthy lifestyle. Overall, some scientists and cardiologist still argue that the aforementioned study did not prove that the grueling working schedule, on its own, is the cause of the irregular heart rhythm. There are, however, plans for further studies with randomized controlled trials.
