Not all types of sitting are equally unhealthy when it comes to heart risk

Not all types of sitting are equally unhealthy when it comes to heart risk

We are frequently warned about the health consequences of leading a sedentary lifestyle. But new research reveals that not all types of sitting are equally unhealthy.


The study by researchers at Columbia University Vagelos College of Physicians and Surgeons found that sitting in front of a TV (known as ‘leisure-time sitting’) was associated with a greater risk of heart disease and death. In fact, study participants who watched four or more hours of TV a day were found to have a 50% greater risk of cardiovascular events and death compared to those who watched less than two hours a day.


However, the study also found that participants who sat for long periods at work had the same level of risk as those who sat the least, suggesting the type of sitting really does have an impact.


Furthermore, the study also revealed that even the most avid TV watchers could reverse the effects of their longer sedentary periods with moderate to rigorous exercise. For example, individuals who watched TV for four hours or more each day, and undertook 150 minutes or more exercise a week, had no increased risk of stroke, heart attack or death.


Speaking about the findings of the study, Keith M. Diaz, Ph.D., assistant professor of behavioural medicine at Columbia University Vagelos College of Physicians and Surgeons, said: “It may be that most people tend to watch television for hours without moving, while most workers get up from their desk frequently. The combination of eating a large meal such as dinner and then sitting for hours could also be particularly harmful.”
