Researchers from the United Kingdom followed 4,500 Scottish men and women, looking at the impact of screen time. They found that people who spent at least two hours of leisure time in front of a TV or computer were more than twice as likely to have a heart attack or other cardiac event.
Those who spent four or more hours in front of the screen were 50% more likely to die.
For these screen people, their weight was higher, their cholesterol, C-reactive protein and other metabolic risk factors were all higher.
Interestingly, there were no negative links with activities such as reading, playing cards or board games.
