Too much tv could shorten life.

Watching too much television can make you feel a bit brain-dead. According to a new study, it might also take years off your life. The more time you spend watching TV, the greater your risk of dying at an earlier age — especially from heart disease, researchers found.

The study followed 8,800 adults with no history of heart disease for more than six years. Compared to those who watched less than two hours of TV per day, people who watched four hours or more were 80 percent more likely to die from heart disease and 46 percent more likely to die from any cause. All told, 284 people died during the study.

Each additional hour spent in front of the TV increased the risk of dying from heart disease by 18 percent and the overall risk of death by 11 percent, according to the study, which was published Monday on the Web site of Circulation, an American Heart Association journal. (The study will appear in the Jan. 26 print edition.)
