Name a common trigger for asthma attacks.

Allergens such as pollen, dust mites, and pet dander are well-documented triggers for asthma attacks. When individuals with asthma are exposed to these allergens, their immune systems may overreact, leading to inflammation and increased mucus production in the airways. This results in symptoms such as wheezing, coughing, and shortness of breath. For many asthma sufferers, managing exposure to these common allergens through avoidance strategies and medications is crucial for maintaining better control over their condition.

Other options, while they may have some relevance to asthma symptoms or exacerbate existing conditions, do not represent as widespread or direct a cause for asthma attacks as allergens do. High altitudes and low humidity levels may affect breathing but typically do not provoke attacks in the same predictable manner. Certain medications, like antibiotics, can also cause issues for some individuals, but they are not common triggers for asthma in the general population. Thus, allergens remain the primary focus when identifying common triggers for asthma.
