Housing factors can play a significant role in respiratory health and greatly exacerbate or increase susceptibility to asthma, allergies, and other respiratory illnesses. For example, numerous home pollutants—dust mites, pet dander, cockroach debris, mold, tobacco smoke, and paint fumes—are known to aggravate asthma. Controlling exposure to these and other triggers in the environment benefits overall respiratory health.
Asthma is a chronic disease in which the airways of the lungs become inflamed or narrowed, resulting in disruptions to normal breathing patterns, often called "attacks" or "episodes." The level of severity of asthma suffered by each individual, and further, the severity of each attack, varies greatly. Symptoms of asthma include wheezing, shortness of breath, a feeling of tightness in the chest, and coughing. According to the Environmental Protection Agency, 8.7 percent of all children (6.3 million) had asthma in 2001. The American Lung Association (ALA) states that asthma accounts for an estimated 3 million lost workdays for adults and 10.1 million lost school days in children annually, making it the leading cause of chronic illness among children. Additionally, ALA ranks asthma among the top ten conditions causing limitation of activity, and the disease costs the United States $16 billion annually.
