The work is health. Do nothing this is the to keep. Not sure that the maxim is true entirely on the scientific level, but Henri Salvador was probably right on one point : the addicts of the job do not make old bones.

The workaholics would be more exposed to the atrial fibrillation, the most common type of heart arrhythmia. It would indeed seem that the duration of work is a risk factor, according to a study conducted at the hospital St. Antonius Nieuwegein (the netherlands), and published in the journal European heart journal.

An additional risk to the heart

Scientists have analyzed the data collected on multiple cohorts representing a total of more than 85 000 people from the United Kingdom, Denmark, Sweden and Finland. They have found that working more than 55 hours per week, instead of 35 to 40 hours, increased the risk of developing atrial fibrillation by 40 %. A result which persists even after controlling for confounding factors, such as smoking, alcohol consumption or obesity.

“An increase of 40 % of the risk is not negligible for people already at cardiovascular risk due to other factors such as age, being a man, diabetes, elevated blood pressure, cholesterol, overweight, smoking, physical inactivity, or a pre-existing heart condition,” explains professor Mika Kivimaki department of epidemiology of the University college of London (Uk), who commented on the study. For people in good health, young and free of these factors, the risk of long working hours remains low. “
