Just 4 hours per day at PC doubles heart risk

Just four hours a day in front of a computer or television could double your risk of a heart disease and thus increase your chances of premature death, a new study has claimed. Researchers at the University College London have found that people who work on computers or watch television for four or more hours a day are 125% more likely to suffer a major heart problem, often leading to death, than those who spend two hours or less. And the study also found there is also a 48% increase in deaths from any cause among people who spend too much time staring at a screen, the Daily Express reported.

Even exercise could not make up for the damage caused, say the researchers. According to the researchers, inflammation and metabolic problems caused by long periods of inactivity could be to blame for the increased risks – prolonged sitting could cause a 90% reduction in a vital enzyme, lipoprotein lipase, that helps prevent heart disease.

Emmanuel Stamatakis of University College London’s public health department, who let the study, said, “Our analysis suggests that two or more hours of screen time each day may place someone at greater risk for a cardiac event. “People who spend excessive amounts of time in front of a screen are more likely to die of any cause and suffer heart related problems,” he added. The researchers have advised people who work in front of a computer to reduce their risk by taking breaks for a brief walk every 20 minutes.
