May is Asthma Awareness Month, and the National Institutes of Health is finding solutions to improve the health of the nearly 25 million people in the United States who currently have asthma. In recent decades, the prevalence of asthma has been increasing, resulting in millions of urgent medical visits and missed days of work and school each year.
Asthma is a chronic, and sometimes fatal, disease in which the airways become inflamed from a variety of triggers in the air, like indoor allergens from dust mites, mold, and cockroaches, and outdoor air pollution.
