Asthma patients reduce symptoms, improve lung function with shallow breaths, more CO2

Asthma patients taught to habitually resist the urge to take deep breaths when experiencing symptoms were rewarded with fewer symptoms and healthier lung function, according to a new study from the Department of Psycholgoy at Southern Methodist University. The findings are from a large clinical trial funded with a grant from the National Institutes of Health's National Heart, Lung, and Blood Institute.
