Exercise-induced asthma is a condition that affects both people with underlying asthma or without any symptoms of chronic asthma.

The condition can affect anyone, but athletes who play cold weather sports and people with asthma are a higher risk of having bronchoconstriction, or tightening of the airways.

“Exercise-induced asthma is asthma that is triggered by active duty,” said Dr Lauren Fine, an allergy, asthma and immunology doctor at the University of Miami. “Basically, it’s people that have no asthma at any other time than when they exercise.”

Fine explains that the function of the airways is to warm and moisten the air we breathe, but when it is done too fast, like during exercise, sometimes the body cannot keep up.
