Final answer:
An exercise-induced asthma attack can best be prevented through the use of prescribed asthma medications before exercise. High-intensity activities or hyperventilating can trigger attacks, whereas medication helps by dilating the airways and reducing inflammation.
Step-by-step explanation:
An asthma attack that is brought on by exercise can often be prevented by taking a prescribed asthma medication prior to exercise. Symptoms of asthma include coughing, wheezing, and chest tightness, and these can be exacerbated by exercise. The narrowing of air passageways during an asthma attack can be reversed with the use of bronchodilators which help to re-expand the airways. Preventative measures, such as the use of corticosteroids, can help to prevent the onset of asthma symptoms by targeting inflammation and reducing airway sensitivity.
It is not advisable to exercise at a very high intensity or to hyperventilate as these can actually trigger an asthma attack. Although breathing cool and dry air may sometimes help, the most effective method to prevent exercise-induced asthma attacks is to use prescribed inhalers or nebulizers before engaging in physical activity.
