A new Cochrane Review, published in the Cochrane Library today, suggests that yoga may have a beneficial effect on symptoms and quality of life in people with asthma, but effects on lung function and medication use are uncertain.
Asthma still continues to be a is a common chronic disease that affects nearly 300 million people worldwide. Symptoms of asthma include wheezing, coughing, chest tightness and shortness of breath.
Yoga has gained global popularity as a form of exercise with general life-style benefits, and recent studies have investigated the potential of yoga to relieve asthma-related problems.
The researchers found some moderate quality evidence from five studies that yoga exercise reduces the impact of asthma on people's quality of life. However, evidence about yoga's impact on the participants' lung function is more uncertain because the results varied. The effects of yoga on medication use and any side-effects of yoga are also uncertain, because only a few very small studies reported these outcomes.
