Researchers at University College London's Department of Epidemiology and Public Health claim the risk of heart disease is significantly higher for those who spend more than four hours a day watching TV or playing computer games.

The study looked into the association between heart attacks and TV-watching and the results showed that the risk of death was increased by 48 per cent.

And the risk of a cardiovascular event was roughly 125 per cent higher in those putting in more than four hours a day, irrespective of factors such as smoking, class and exercise.

Unfortunately that also applies to those working on computers every day, leaving those in sedentary jobs with a real health problem.

Scientists believe the increased risk may be as a result of the effect prolonged periods of sitting has on cholesterol and inflammation.

Dr Emmanuel Stamatakis, whose research was published in the Journal of the American College of Cardiology, said: "These risks may not be mitigated by exercise, a finding that underscores the urgent need for public health recommendations."
