What are allergies?
Allergies are an overreaction of your body’s immune system to a harmless foreign substance (like pollen for example) that enters the body. Substances that cause this reaction are called allergens. The job of your immune system is to identify foreign substances in the body and get rid of them. An allergic reaction occurs when an allergen enters the body and your sensitive immune system overreacts to it by producing antibodies to fight off the allergens. These antibodies in turn cause the release of histamines and other chemicals that result in symptoms such as a runny nose, swelling, itchy and watery eyes, rashes, or asthma.
