Is sitting killing you slowly and painfully?

A sedentary lifestyle kills

The work performed in an office is primarily sedentary work with minimal energy expenditure. Office work has traditionally been considered as a 'low risk' occupation in terms of chronic health outcomes, it may in fact increase the risk of mortality and cardiometabolic disorders due to overall accumulated sedentary time.


Many office workers spend more than 6 hours of their day in a sitting position at their desk. The same people then sit in their car or train on their way home followed by additional sitting time on the couch in front of the TV. The energy expenditure while sitting is a very low 1.25 kilojoules per minute. This work rate is doubled to 2.5 kilojoules per minute when standing!

According to researchers there is a growing body of evidence that people who do physically demanding jobs are fitter, healthier and less likely to suffer from fatal heart attacks than their less active colleagues. According to a University of Sydney study, people who sit for 8 to 11 hours a day increased their risk of dying by 15 percent! Other researchers claim that sitting may have more to do with obesity than the lack of physical activity.

Consequences of a sedentary lifestyle increase the risk of:

  • mortality
  • cardiovascular disease
  • diabetes
  • high blood sugar level

Even more worrying is the research that suggests exercising doesn't necessarily counteract the damage caused by sitting all day in the office.
