People who spend more hours in front of the television are at greater risk of dying, or developing diabetes and heart disease, with even two hours of television a day having a marked effect, according to a U.S. study.
Every day, U.S. residents spend an average of 5 hours watching television, while Australians and some Europeans log 3.5 to 4 hours a day, said researchers led by Frank Hu, at the Harvard School of Public Health, informs Reuters.
Dr Iain Frame, of Diabetes UK, said the findings should be a wake-up call about the risk of leading a sedentary lifestyle. He said evidence suggests physical activity can reduce the risk of type-2 diabetes by over 60%.
Maureen Talbot, of the British Heart Foundation, said: "I'm sure we've all unintentionally lost evenings slumped on the sofa in front of the TV snacking on crisps and biscuits and drinking sugary drinks or alcohol. But it's important that this doesn't become a regular activity, according to BBC News.
