What is exercise induced asthma?

Dr Louisa Draper

"If you are diagnosed with exercise induced asthma, there are treatments available to help. If your asthma is under control, then there is no reason why you can’t exercise safely and keep fit without worrying about triggering your asthma."

Exercise induced asthma is a type of asthma where you only experience the symptoms when you exercise. 

Some people who have asthma (diagnosed or undiagnosed) find that exercising can bring on the symptoms of the condition. Physical activity of any kind, whether mild or vigorous, can trigger symptoms or bring on an asthma attack

Asthma symptoms are triggered when the airways in the lungs contract and narrow, leading to wheezing, shortness of breath, coughing, and tightness in the chest. When you exercise, you will usually start breathing faster through your mouth instead of through your nose. When you breathe in through your mouth, the colder and drier air can aggravate the sensitive airways and cause them to narrow, causing asthma symptoms. 

If your asthma is not adequately controlled with the right medication, then exercise could worsen the symptoms. If you don’t already have a diagnosis of asthma, and notice that you get any of these symptoms when exercising, speak to your doctor.
