Working 10 or 12 hours a day?
New research shows that people working 10 or 11 hours a day are more likely to suffer serious heart problems, including heart attacks, than those clocking off after seven hours, researchers said on Tuesday.
An 11-year study of 6,000 British civil servants, shows a clear link between long hours and coronary heart disease which experts said may be due to stress.
In the study the risk of having a heart related problem such as heart disease, heart attack and angina was 60% higher for those who worked three to four hours overtime.
According to Dr. Marianna Vitanen, an epidemiologist at the Finnish Institute of Occupational Health and University College London, there does not seem to be an associated risk with working one or two hours more than your normal seven hour day.
Virtanen said it was possible the lifestyle of people working long hours deteriorated over time, for example as a result of poor diet or increased alcohol consumption and lack of exercise.
Long hours may be associated with work-related stress, which interferes with metabolic processes, as well as "sickness presenteeism," whereby employees continue working when they are ill. |
