Hay Fever (Allergic Rhinitis)

Allergic Rhinitis (commonly called Hay Fever) is caused by inhaling airborne particles to which you may be allergic. These are called allergens. Out of the more than 67 million Americans who suffer from allergies, 24-40 million suffer from an airborne allergy, such as hay fever or allergic rhinitis.

These allergies are caused by:
Pollen, Pet dander, Dust particles and Mold spores

Plants like ragweed, cattail and maple tree release their pollen to initiate their reproductive processes with nearby plants of their species. Pollens are carried by the wind, so not all of them reach their targets, and instead they land on you. For that reason, too, pollen is frequently present in the air we breathe. Weather forecasts are important signals - pollen can't travel in the rain.

If you are an individual sensitive to pollen, you will experience an allergic reaction.

Taking into account the airborne allergens listed above, there are two forms of allergic rhinitis: Seasonal Allergic Rhinitis (also called Hay Fever or Pollinosis) and Perennial Allergic Rhinitis. (Click HERE to learn about treatment options).
