Heart Disease: Can Too Much TV Affect Your Heart?
Heart disease risks until now haven't included sitting in front of a TV or computer screen.
But a new study has found two hours of screen-time a day increases the risk of cardiovascular events, such as heart attacks, by 125 percent.
The findings were published in the Journal of the American College of Cardiology.
Lead author of the study, Emmanuel Stamatakis of the University College London told AFP:
"It is all a matter of habit. Many of us have learned to go back home, turn the TV set on and sit down for several hoursit's convenient and easy to do.
"But doing so is bad for the heart and our health in general."
The study surveyed more than 4,500 adults and compared their self-reported TV or computer usage.
It then compared this with the instances of cardiovascular events or death.
Those who spent more than four hours in front of a screen had about 50 percent higher chances of dying of heart disease, than those who spent less that 2 hours, AFP reports.
