According to preliminary research presented at the scientific session of the American Heart Association in 2017, the risk of blood clots increases with prolonged TV viewing, even when a sufficient amount of physical activity.
"By itself, the TV does not bear the risks, but while watching people like to eat and sit still for a long time", - says Mary Cushman, author of the study, Medical College Larner professor at the University of Vermont in Burlington.
Prolonged TV viewing is associated with heart disease and blocking arteries, but this is the first study of blood clots in the legs, arms and lungs, known as venous thromboembolism or VTE.
At the risk of atherosclerosis study among 15,158 participants in middle age (45-64 years) the researchers found that the risk of venous thromboembolism:
- 1.7 times higher in those who are very often watching television, compared with those who rarely watches it or not watching at all;
- 1.8 times higher in participants who comply with the recommendations for physical activity, but very often watch TV;
- above the limbs and lungs when watching television; while obesity was more common in people who watch more TV channels, in the study, only about 25 percent of the risk attributable to the presence of obesity .
"Think about how best to spend the time to live a full and healthy life. You can put a treadmill or an exercise bike in front of the TV and move during playback. Or can delay watching TV for 30 minutes and take a walk and see favorite show in the recording later, "- says Cushman.
In the United States of venous thromboembolism suffer from 300 000 to 600 000 people, is the most common cardiovascular disease after heart attack and stroke. Although venous thromboembolism often occurs in people 60 years and older, the risk may occur at an earlier age.
Avoiding prolonged TV watching, patients reduce the risk of venous thromboembolism, maintain a healthy weight and an active lifestyle.
"Doctors should be interested patients about physical activity and the time they spend watching TV or playing computer games," - says Cushman. - If you have an increased risk of venous thromboembolism due to recent surgery, pregnancy, cancer or previous clots, the doctor may prescribe medication to thin the blood, or recommend wearing compression stockings.
