An article, posted by The New York Times in their Well section, described a study to check the health effects of prolonged sitting in children. They found that, just like in adults, prolonged sitting leads to decreased vascular dilation which can raise blood pressure and lead to cardiovascular disease in the future.
As iPads, video games, Netflix, and other attention-grabbers have become more prevalent, kids are sitting more and more. One researcher in the article even said, "I was surprised by how easy it was to get the girls to stay still for three uninterrupted hours."
The study concluded that we should avoid prolonged sitting. Getting up every hour to walk around for a few minutes can help undo the damage done by sitting.
