Environment & Asthma

Asthma may be triggered by allergens and irritants found inside buildings and in outdoor air. It is important to know your specific triggers and to take steps to minimize your exposure. Since Americans spend up to 90 percent of their time indoors, exposure to allergens and irritants found in homes and schools can play a major role in causing asthma episodes.
