Just in case you don’t have enough reasons to turn off the TV, here’s one that will take your breath away—literally. In a new UK study, children’s TV watching is now linked to incidence of asthma. Anything upwards of two hours a day doubled children’s risk of developing this condition. While TV is not directly responsible, it is a symptom of a sedentary lifestyle, and hours spent in front of the tube could be better spent being active. Some scientists believe that children who abstain from physical activity may not be breathing deeply enough, so their airways are not sufficiently stretched, making asthma more of a threat. Moms everywhere can breathe a sigh of relief, as you have yet another reason to hide the remote.
