We all know that too much inactivity is bad for us, but according to a recent study by The Journal of the American College of Cardiology it could be even worse than we thought.
There are an awful lot of people out there who spend all day at a desk job, and then all evening in front of some from of screen (be it TV or PC) and then try to counterbalance this with a couple of hours at the gym. Well according to this recent piece of research by The Journal of the American College of Cardiology it seems that it doesn’t work that way.
The study followed 4,512 middle-aged Scottish men for a little more than four years on average. It found that those who said they spent two or more leisure hours a day sitting in front of a screen were at double the risk of a heart attack or other cardiac event compared with those who watched less. Those who spent four or more hours of recreational time in front of a screen were 50 percent more likely to die of any cause. It didn’t matter whether the men were physically active for several hours a week — exercise didn’t mitigate the risk associated with the high amount of sedentary screen time.
Recreational screen time has an “independent, deleterious relationship” with cardiovascular events and death of all causes, the paper concluded, possibly because it induces metabolic changes.
