British researchers reported that Children who watch television for more than two hours a day have twice the risk of developing asthma. Asthma affects more than 300 million people worldwide and is the most common children’s chronic illness. Symptoms include wheezing, shortness of breath, coughing and chest tightness.
A study published in the journal Thorax may help link asthma, estimated to account for one in 250 deaths globally each year, to obesity and lack of exercise, experts said.
“There has been a recent suggestion that breathing patterns associated with sedentary behavior could lead to developmental changes in the lungs and wheezing illnesses in children,” Andrea Sherriff of the University of Glasgow and colleagues wrote.
