Understanding What Hay Fever Actually Is
Hay fever is an allergic reaction to airborne allergen particles like pollen, mold spores, pet dander, or dust mites that trigger an immune response in the nasal lining and eyes. The immune cells mistakenly recognize these harmless substances as threats and mount an inflammatory attack, releasing chemicals that cause the characteristic symptoms of swelling, itching, redness, and watery discharge. This misbehavior of the immune system, which exists to prevent infections, is what creates the misery of hay fever.
