Myth about Allergies
Allergies are essentially a harmless problem
Allergies and Asthma affect 1:5 people. Numerically this is more than heart disease, diabetes, and cancer combined (see www.aafa.org for alarming statistics on the growing direct and indirect costs of asthma and allergies). If left untreated, allergies can lead to impaired quality of life, including sleep disturbances and missed days of school or work.
