Do you have the habit of sitting glued to the idiot box every day? Beware, you may be at nearly twice the risk of developing blood clots, cautioned a study.

The risk of blood clots in the veins of the legs, arms, pelvis, and lungs known as venous thromboembolism or VTE increases with the amount of time spent watching television even if people get the recommended amount of physical activity later, caution the researchers.

"Watching TV itself isn't likely bad, but we tend to snack and sit still for prolonged periods while watching," said Mary Cushman, Professor at the University of Vermont in Burlington.

In the study, the team of researchers examined close to 15,158 middle-aged (45-64 years) participants.

Those who watched TV "very often" were at 1.7 times higher risk of developing blood clots compared with those who watch TV "never or seldom" explained the research.

The people, who met recommended guidelines for physical activity and reported watching TV "very often", had 1.8 times higher risk compared to those who reported watching TV "never or seldom".

"Think about how you can make the best use of your time to live a fuller and healthier life. You could put a treadmill or stationary bike in front of your TV and move while watching," said Cushman.

The results were presented at the American Heart Association's Scientific Sessions 2017 in California.

Previous studies too have associated prolonged TV viewing with heart disease involving blocked arteries.

Although venous thromboembolism is more common in people 60 and older, it can occur at any age. For it isn't only related to age, but can occur at any age and most certainly there is a high chance for women who spend more time watching TV, said researchers.

Besides avoiding prolonged TV watching, one can also lower the risk of venous thromboembolism by maintaining a healthy weight and staying physically active. Among the tips, researchers are suggesting that we should keep moving around and give breaks while watching the TV.
