Why Do Nasal Allergies Make Me Feel Bad?
Sneezing. Runny nose. Itchy, stuffy nose. You know the symptoms of nasal allergies (also called "hay fever" or "allergic rhinitis"), but do you know why they make you feel this way?
Your body's immune system is designed to fight off substances that can make you sick — things like harmful bacteria. Symptoms like sneezing or a runny nose are your body's way of trying to fight off harmful substances.
But when you have allergies, your immune system is oversensitive. It mistakes an allergen — one or more normally harmless substances (like pollen, pet dander, or mold; it's different for different people) — for a foreign invader and tries to fight it off.
