A Discovery Health answered. The Food and Drug Administration estimates that there are approximately 36 million people in the United States who suffer from seasonal allergies. This condition is also called by its common name of hay fever, or, by its technical name, allergic rhinitis. While it may provide little comfort, the pollen that you are reacting to is actually harmless. The runny noses, scratchy eyes and headaches you endure actually result from a case of mistaken identity. Your body believes that the pollen in the air is actually dust mites or fungal spores. In response, it releases histamine-a natural chemical that is part of the body's immune system response.
Dust, cats, peanuts, cockroaches. An odd grouping, but one with a common thread â people can be allergic to them. Allergies are a major cause of illness in the United States. Up to 50 million Americans, including millions of kids, have some type of allergy. In fact, allergies lead to about 2 million missed school days each year.
