Which of the following is a common trigger for asthma attacks?

Allergens are indeed a common trigger for asthma attacks because they can provoke bronchoconstriction and inflammation in individuals with asthma. Common allergens include pollen, dust mites, animal dander, mold spores, and certain foods. When a person with asthma is exposed to these allergens, their immune system may overreact, leading to symptoms such as wheezing, coughing, shortness of breath, and chest tightness.

While pollution, obesity, and high altitudes can have impacts on respiratory health and may exacerbate asthma symptoms, allergens are directly linked to the phenomenon known as allergic asthma. In this condition, the inflammation and constriction of airways occur specifically in response to exposure to those allergy-inducing substances. Understanding the role of allergens can help individuals manage their environment and reduce exposure to known triggers, which is crucial for effective asthma management.
