Asthma Triggers

Living with asthma means becoming an expert on what sets off your symptoms. When you breathe in certain substances or experience specific conditions, the muscles around your airways tighten and inflammation increases, making it hard to breathe. Recognizing that these “triggers” differ from person to person empowers you to take control of your health and prevent flare-ups before they start.

Common asthma triggers fall into several categories. Inhaled allergens like dust mites, mold, pet dander, and pollen can spark an attack. Irritants such as tobacco smoke, outdoor and indoor air pollution, strong fragrances or aerosol sprays also worsen symptoms. Viral respiratory infections, vigorous exercise, emotional stress, sudden weather changes, and even certain medications (like aspirin) can provoke asthma episodes as well.

Pinpointing your personal triggers often begins with a symptom journal. Note when and where breathing problems occur—at home, work, or during outdoor activities. Sharing this pattern with me helps identify likely culprits. Allergy testing can reveal sensitivities, but pairing test results with your symptom logs gives the clearest picture of what’s setting off your asthma.

Once you’ve identified your triggers, focus on reducing exposure. Use high-efficiency air filters, wash bedding in hot water, and keep pets out of your bedroom to limit allergens. Avoid smoke and check pollen and air quality forecasts before outdoor activities. If a trigger can’t be avoided, ask me about taking medication beforehand.
