Asthma attacks occur when the muscles of the airways tighten, causing them to narrow.
When you exercise, you tend to take in air more quickly through your mouth than usual.
For those with exercise-induced asthma, cooler air isn’t well tolerated.
The same is true if you are presenting with these symptoms and do not have an asthma diagnosis.
You’ll then exercise until you reach 85% of your expected maximum heart rate.
Immediately after you stop exercising, your practitioner will measure your FEV1 again.
If it has dropped 10% or more, you’re likely to be diagnosed with EIA.
The test may be repeated to ensure accurate results.
Studies show that these tests can offer results as accurate as exercise tests.
Limiting your exposure to pollution andallergenswhile you exercise can also help.
Medication
Medication may also be required to manage your symptoms.
These benefits can protect you against future exacerbations, as well as improve your overall health.
Finally, don’t underestimate the importance of warming up.
But with medication and patience, the episode should pass.
If you feel that your breathing isn’t improving after treatment, seek emergency help immediately.
Summary
Exercise-induced asthma (EIA) happens when exercise and exertion lead to bronchoconstriction.
People diagnosed with asthma often experience EIA.
Causes include cold air exposure and a lack of moisture in the airways.
Treatment is similar to asthma care, including inhaler use.
Avoid EIA causes when possible and use your medication when necessary.
