What Causes Nose Allergies?

what causes nose allergies
Nose allergies can be caused by irritants such as pollen, animal dander, and household dust

Nose allergies (nasal allergies or rhinitis) occur when your immune system has an allergic reaction to an otherwise harmless substance. 

Your nose produces mucus, which is normally thin and clear and helps protect your lungs from dust, debris, germs, and allergens. If you have an allergy, your body may produce too much mucus, leading to stuffiness or a runny nose.

Common triggers of nasal allergies include:

  • PollenPollen causes seasonal allergies, also called hay fever, which usually peaks during certain times of the year. Tree pollen peaks in the spring, grass pollen often peaks in the summer and weed pollen is seen in the fall. Most nasal allergies continue through the pollen season and can last for about 4-8 weeks. 
  • Animal dander. Dander from cats, dogs, horses, rabbits, and other animals can also cause nasal allergies, with symptoms usually lasting for a few hours.
  • Household dust. Household dust contains many allergens, including dust mites and mold (in areas of high humidity). These types of allergens can cause perennial allergic rhinitis, which trigger daily symptoms all year round.
