People with asthma have airways that are very twitchy or sensitive.
These airways may react to things that can (or cause) asthma symptoms. When a person with asthma breathes in an asthma trigger, their airways may swell up, tighten up, and produce too much mucus.
The person may then start to wheeze or cough, and may develop congestion, itchy eyes, or a runny nose. Because of this, it is important for people with asthma to find out what their asthma triggers are and learn ways to control them. Many different things in the indoor environment can be asthma triggers and can affect people with asthma.
It has been recognized that because Americans spend so much time indoors over 90 of the day is spent at home, school, and/or work it is important that people with asthma maintain healthy indoor environments that reduce these exposures to indoor triggers of asthma. Not only can poor indoor air quality make the symptoms destiny of someone who already has asthma worse, but it may also play a role in the development of asthma in more susceptible people, like small children.
In addition, some people with asthma may be more sensitive to certain indoor air triggers than other people with asthma are.
To help you find out what these asthma triggers are, people with asthma often keep a written record of their activities. Writing down what they were doing, and where, whenever there are symptoms will help to find out if being near certain things causes the asthma symptoms. For example, if asthma symptoms are worse when making the bed or vacuuming, dust mites may be a trigger.
Indoor air triggers can be classified as either irritants or allergens. Irritants include gases such as volatile organic compounds (VOC) that can aggravate the airways and cause inflammation. Irritants also include small particles that can reach the lower regions of the respiratory tract and cause inflammation.
Examples of irritants include the following: Tobacco smoke, a well-documented respiratory tract irritant, can induce wheezing or an asthma attack in people with asthma. Smoke particles remain in the air long after the cigarette has been put out.
