Allergic rhinitis or hay fever occurs when your body has an allergic response to indoor or outdoor allergens such as pet dander, dust mites, mold, bee venom, or pollen. When you experience allergies, your immune system creates antibodies against specific allergens it identifies as dangerous, even if they are not. Allergies vary in severity from one person to another. Most of the time, allergies cause mild symptoms, such as a runny nose, itchy eyes, sinus pressure, nasal congestion, skin rashes, and sneezing. Fortunately, many treatments for allergic rhinitis can help relieve your symptoms.
Avoiding your allergy triggers is the most obvious and useful thing you can do to prevent allergic reactions. An allergist can identify which allergies you have. With this information, you can avoid your allergy triggers. For instance, if you are allergic to grass pollen, don't go outdoors or open your windows when grass pollen levels are high. If you are allergic to dust mites, vacuum and dust frequently.
