PRESS TV: Study: Work-related stress can kill

A new study shows stressful jobs can really kill people, with raising the risk of heart diseases and disrupting the body’s internal systems.

The study involving more than 10,000 British civil servants also suggest stress-induced biological changes may play a more direct role than previously thought, said Tarani Chandola, an epidemiologist at University College London.

«This is the first large-scale population study looking at the effects of stress measured from everyday working life on heart disease,» said Chandola, who led the study. «One of the problems is people have been skeptical whether work stress really affects a person biologically,» Reuters reported.

The researchers measured stress among the civil servants by asking questions about their job demands such as how much control they had at work, how often they took breaks, and how pressed for time they were during the day.

The team conducted seven surveys over a 12-year period and found chronically stressed workers – people determined to be under severe pressure in the first two of the surveys – had a 68 percent higher risk of developing heart disease.

Behavior and biological changes likely explain why stress at work causes heart disease, Chandola said. For one, stressed workers eat unhealthy food, smoke, drink and skip exercise – all behaviors linked to heart disease.

Heart disease is the world’s leading cause of death. It is caused by fatty deposits that harden and block arteries, high blood pressure which damages blood vessels, and other factors.
