If you watch a lot of TV then this article might encourage you to get out a bit more. It suggests that every hour spent TV increases the risk of dying from heart disease by almost a fifth. Researchers monitored 8,800 adults over a six year period to see what impact TV had on their long term health. The results found that each hour spent in front of the TV increased the risk of heart disease related death by 18%. During the follow up period there were 284 deaths, 87 due to cardiovascular, or heart and artery disease, and 125 from cancer. The scientists warned that any prolonged sedentary behaviour such as sitting at an office desk can have the same effect and that even those who are not overweight are still at risk.
