How Weather Affects Asthma:
Extreme weather---high heat and humidity, dry wind, rain, and bitterly cold air---can trigger an asthma attack, says Kenneth Mendez, President and CEO of the Asthma and Allergy Foundation of America. Asthma is an inflammation of the airways, and extreme weather changes the type of air you're breathing, which can irritate the airways. Very humid air, for example, is heavier and harder to breathe. Cold, dry air dehydrates the bronchial tubes (part of your airways), causing them to narrow and restrict airflow. Airborne allergens (pollen, mold) can also cause an asthma flare-up.
HEAD IT OFF
People with asthma should keep an eye on the forecast and limit outdoor activity when triggers are strongest. To track air quality in your area, get the Environmental Protection Agency's EPA AirNow app (free).
