According to the National Institute of Environmental Health Sciences (NIEHS), allergens in the environment can trigger seasonal allergies and asthma. Asthma is an inflammatory disease of the lung and is now the most common chronic disorder in childhood. The prevalence has increased over the years. According to CDC Vital Signs 1 in 12 people have asthma in the United States. Oxygen absorption in the lungs is a crucial function of the body. With asthma, the airway becomes inflamed, swollen, and narrow. Less air is able to get to the lung tissue. Some describe feeling as if an elephant is sitting on their chest.
The US Department of Housing and Urban Development conducted an extensive survey, known as the National Survey of Lead Hazards and Allergens in Housing. The results were published in the Journal of Allergy and Clinical Immunology.

Nearly two-thirds of American homes have cockroach allergens.
