For a long time, the cause was thought to be cold air. However, recent studies found dry air to be a more likely culprit. Cold air contains less moisture than warm air. Breathing in cold, dry air dehydrates the air passages. This causes them to narrow, reducing air flow. Other factors, such as chlorine or other fumes, can irritate the lining of the airways and contribute to breathing difficulties.</p> </section> </conbodydiv> </conbody> </hecsConcept> <hecsConcept contentType="http://ontology.mayo.edu/ContentCategories/RiskFactors" policy="did:mcid:PDkv3FCzsA4FPiHVvT1zRc" reviewedOn="2022-12-07T06:00:00.000-06:00" workId="did:mcid:C8S3nPRfEt7sKhBBYom8iz:2026-10-08" xml:lang="en"> <title>risk factors exercise induced asthma consumer</title> <titlealts> <titleSimple> <ph keyref="titleSimple-risk-factors">Risk factors</ph> </titleSimple> </titlealts> <conbody> <conbodydiv platform="richtext"> <section> <p>Exercise-induced asthma is more likely to happen in:</p> <ul> <li> <b>People with asthma.</b> About 90% of people with asthma have exercise-induced asthma.
