What Are the Common Triggers of Allergic Asthma?
Allergic asthma is often triggered by airborne allergens that cause an exaggerated immune response in sensitive individuals. Common triggers include pollen from trees, grasses, and weeds, which can lead to seasonal asthma symptoms, particularly in the spring and fall. Pet dander, which consists of tiny flakes of skin shed by cats, dogs, and other animals, can also be a significant trigger, especially for people who live with pets indoors.
Dust mites, microscopic organisms that thrive in bedding, upholstery, and carpets, are another prevalent trigger for allergic asthma. These mites are present year-round, which means individuals may experience chronic symptoms if they are exposed frequently. Mold spores, particularly in damp or humid environments, can exacerbate asthma as well, causing flare-ups when inhaled. Environmental irritants like cigarette smoke, air pollution, and strong odors (e.g., from perfumes or cleaning products) can also provoke asthma symptoms, although these may affect both allergic and non-allergic asthma sufferers.
Identifying specific triggers through allergy testing is a crucial part of managing allergic asthma. Once the triggers are known, individuals can take steps to avoid or minimize exposure, whether that means using air filters, regularly cleaning bedding, or staying indoors during high pollen counts.
