What Are Allergies?
Your immune system acts so exaggerated that it attacks something called an allergen, causing an allergic reaction. An allergen is a substance, like pollen or pet dander, that is safe for the vast majority of the population. However, allergies manifest themselves when the immune system tries to fight off the allergen as if it were a germ or a virus, instead of fighting a germ or a virus. When the allergens invade your immune system, it responds by producing an antibody, which is the protein responsible for fighting the allergen. This condition causes sensations such as sneezing, itching, hives, and shortness of breath. Rest can be used to treat these usually mild symptoms. Additionally, allergies can also manifest as a dangerous reaction known as anaphylactic shock, which has a lethal effect.Symptoms
