Are you football fan catching the World Cup being played in South Africa on television? If so, new research has indicated that it is not only the human eyes and brain that gets affected by spending time before the television.

Scientists have warned that every hour spent in front of the television increases the risk of death from a heart disease. So, every match you watch on television heightens the chances of a heart disease by over seven percent.

A study conducted by the Medical Research Council across Norfolk in England reviewed the behavioral changes in a sample size of 13,197 healthy middle-aged men and women. And the results were alarming as it found that one in 35 died from heart disease over a ten year period.

The report, published in the International Journal of Epidemiology, listed out 373 members of this sample group has having died from heart disease over a decade, indicating that the amount of time spent watching television was a crucial marker of possible death from heart disease.

The research team also inferred that an estimated eight per cent of these deaths could have been avoided if television viewing times had been reduced from the British average of four hours per day to just about an hour per day.

In Asian countries where average television viewing is substantially higher, especially among middle aged women, the fatality rate could be much higher though no research has yet been conducted on the adverse impact of television viewing in these regions.

The research group also took into account some other parameters while making the assessment. These include factors like smoking, obesity, lack of exercise and poor quality of diet, says co-author of the study Dr. Katrien Wijndaele.

The research has proved that the human body is not designed to sit for long periods. And if we spend too much time watching television, the risk of heart ailments goes up, Dr. Wijndaele said while admitting that more research is required to check whether other sedentary activities like working on a computer also generates the same results.

So, the next time you sit down on the coach to watch your favorite game on television, beware that watching someone else play and stay healthy could actually result in increased health risks for you.
