"Children who spend hours in front of the television are at greater risk of developing asthma than those who are more active, a study has found.
Youngsters who watched more than two hours of TV a day were twice as likely to get the respiratory condition as children who watched less, according to research by British scientists.
The greater risk of asthma was not directly caused by watching television, which was used only as an indicator of how sedentary the children's lifestyles were.
The finding builds on recent work that points to a link between asthma and low levels of physical activity. Some scientists believe that inactive children do not inhale deeply and regularly enough, which helps to stretch the airways and may make them less prone to asthma."
