Every hour spent in watching TV, DVDs and videos as an adult reduces lifespan by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.

The research shows that a sedentary（久坐的） lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.

The researchers set out to calculate the overall risk to lifespan from watching television. Their research involved more than 11,000 people over the age of 25.

Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be connected with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."

The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.

But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.

Earlier this year, a separate study suggested the risk of developing diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.

England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."
