What can prolonged exposure to allergens lead to in respiratory health?

Prolonged exposure to allergens can lead to an increased risk of chronic respiratory conditions due to the inflammatory responses they trigger in the respiratory system. When allergens such as pollen, dust mites, mold, or pet dander are inhaled, the immune system may react excessively, resulting in inflammation and airway constriction. This chronic inflammatory response can cause lasting changes in the airways, potentially leading to conditions such as asthma, allergic rhinitis, and chronic obstructive pulmonary disease (COPD).

Over time, the persistent inflammation can damage lung tissue and impair lung function. This makes individuals more susceptible to respiratory infections and can exacerbate existing respiratory issues. Regular exposure to allergens can also lead to the development of airway hyperresponsiveness, where the airways become overly sensitive and can react strongly to various stimuli, further complicating respiratory health.

Other options such as development of anxiety, improvement in lung function, and reduction in mucus production are less relevant in the context of allergen exposure. While it is true that respiratory issues can impact mental health, prolonged allergen exposure primarily affects physical respiratory health rather than directly causing anxiety. Improvement in lung function is not expected; instead, it typically deteriorates due to chronic inflammation. Similarly, mucus production often increases, as the body
