Study: Sedentary Kids Have Narrowed Arteries
A new study says that kids who spend too much time watching TV or on the computer, have a higher risk of developing narrowed arteries in the back of their eyes. That's an early sign of high blood pressure and future heart disease.
The study found that kids who exercised for an hour or more each day had wider arteries than children who spent a half hour or less each day, being active.
The study included results from over 1,400 children. It was published in Arteriosclerosis, Thrombosis and Vascular Biology: Journal of the American Heart Association.
