Dust mite allergy is a common condition caused by tiny creatures called dust mites that live in household dust. These mites thrive in warm, humid environments and feed on dead skin cells. When people with this allergy come into contact with dust mite waste or body parts, they may experience symptoms like sneezing, runny nose, and itchy eyes. To manage dust mite allergy, it is important to reduce exposure to these allergens. This can be done by regularly cleaning bedding, using allergen-proof covers on pillows and mattresses, and maintaining low humidity levels in the home.
