Allergies are the sixth leading cause of chronic illness in the United States, according to The American College of Allergy, Asthma & Immunology (ACAAI).
Some of the 50 million Americans who experience this condition each year will be affected by common seasonal allergies. In fact, approximately 8% of U.S. adults have allergic rhinitis, a condition often called hay fever. Hay fever tends to flare up in spring, summer and early fall.
