Asthma Triggers

Recognize and remove asthma triggers

Your child’s airways are very sensitive to objects, acts or events that do not normally bother people who don’t have asthma. They are called triggers, when you are near or come in contact with them, an asthma episode may start. Exposures to triggers build up over time. It may take one exposure to one trigger or numerous exposures to several triggers for asthma symptoms to begin. It depends on how sensitive the lungs are at the time of the exposure.

To understand this lets compare your lungs to a cup of water. The level of the water represents the twitchiness of the airways as the airways are exposed to numerous triggers over a period of time. The cup of water may already be half full because you are constantly around a certain trigger like cigarette smoke. You are having no symptoms but sensitivity of the lungs has increased as well as the swelling of the airways. Then over the next couple of weeks/days the lungs become exposed to numerous triggers. The twitchiness and swelling (inflammation) of the airways increases. The water level in the cup begins to rise. Then at some point the lungs are so twitchy and inflamed that the person begins to have asthma symptoms, and an episode begins. The cup of water overflows.

To make the airways less sensitive, you must reduce the exposure to triggers that the lungs are sensitive to. Everyone’s lungs are sensitive to different triggers and may take different amounts of exposure to triggers before an episode begins. Below is a list of triggers and steps you can take to reduce exposure to certain triggers. At the very least these changes should be made in the child’s bedroom. Although, it would be very helpful to make these changes in the entire house. Your healthcare professional will talk with you about steps to take to eliminate or reduce triggers in your child’s surroundings.
