People who spend at least four hours a day with TV, video games, computer or behind the wheel of a car twice as prone to cardiovascular problems, and have 50 percent more likely to die earlier

People who spend at least four hours a day with TV, video games, computer or behind the wheel of a car twice as prone to heart disease, stroke and other cardiovascular problems, and are 50 percent more likely to die earlier.

The problem is not the TV or computer, but in sitting, says Health magazine. Although it is still not clear why the sitting is harmful, studies conducted on animals have shown that prolonged sitting slows activity of enzymes that dissolve blood fats, especially cholesterol and triglycerides.
Prolonged sitting at a computer is bad for your health even if you exercise regularly. And when that does not matter whether you’re sitting in your office, school, car, in front of a computer or television, but it is crucial only the total number of hours spent in a sitting position, according to the Associated Press.
Tim Armstrong, a physical activity expert at the World Health Organization (WHO), said that people who exercise every day, but spend much time sitting, might benefit more if they exercise on several occasions during the day, instead of just one exercise.
“So far we do not have enough evidence yet to say how much sitting is bad,” said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge, “But it seems that the more you sit up and interrupt, the better,” he said.
