Asthma affects 300 million people worldwide. Research pooled nearly 700 patients and found that physical training lasting for at least 20 to 30 minutes, two to three times a week, for at least six weeks improves physical fitness in patients with asthma. This physical training did not worsen asthma symptoms and it significantly improved health-related quality of life.
If you have asthma, make sure that your symptoms well controlled before you start exercising. The goal of asthma treatment/medication is so that you live your life to the fullest!
