Watching TV or being in front of the computer is a good time killer but research have found that spending to much time on both dramatically increase the risk of heart disease and premature death from any cause. The data shows that people who spend more than 4 hours a day in front of TV or computer are more that twice as likely to have a major cardiac compared to those who spend less than 2 hours a day.
The research also suggest that metabolic factors and inflammation may partly explain the link between prolonged sitting and the risk to heart health. These associations were independent of traditional risk factors like smoking, hypertension, BMI, social class, and exercise. The study has been published in January 2011 issue of the Journal of the American College of Cardiology.
