Having moderate to life threatening allergic reactions is an extremely common issue throughout the United States and the world. According to the Allergy and Asthma Foundation of America or AAFA, one in every five Americans or an estimated 50 million Americans suffer from all types of allergies including indoor and outdoor, food & drug, latex, insect, skin, and eye allergies.


Because allergies are hard to treat, the best way to avoid it is to find out what you are allergic to and then limit your exposure to it as much as possible. This can be a very tricky proposition especially with seasonal allergies because each part of the United States is home to a wide variety of different weeds, trees and native grasses.


To solve the problem, authorities in the country identified eight primary allergy “zones” or allergy regions in the United States. The primary purpose of identifying these different allergy regions is to be able to better focus in on the most likely suspects for your seasonal allergies. You can find reference information related to your particular zone to get a basic idea of what’s currently spreading pollen in your area, and compare it against the things to which you’re normally exposed. Your doctor will likely consult an allergy zone chart to decide which allergens to use in an allergy skin test when determining the source of your allergies. This will help find the most effective treatment to alleviate your symptoms. In addition, if you move from one zone to another and immediately experience a recurrence in seasonal allergies, then you may be allergic to something that’s common to both zones.
