What are common triggers for asthma attacks?

Asthma attacks are often triggered by various environmental and physiological factors, with allergic reactions being one of the most common. Allergens such as pollen, pet dander, dust mites, mold, and certain pollutants can irritate the airways in individuals with asthma, causing inflammation and difficulty breathing. Smoke from cigarettes or other sources can also exacerbate these reactions. These triggers lead to the constriction of airways and the production of excess mucus, both of which contribute to the symptoms of an asthma attack.

While other factors like excessive exercise, cold weather, high humidity, and even genetic predispositions can influence asthma severity and frequency, the immediate triggers that result in an asthma attack are primarily linked to environmental allergens and irritants, making the first option particularly significant in the context of common triggers for asthma attacks.
