What causes rhinitis?

Allergic rhinitis is triggered by allergens. Allergens include, but are not limited to, pollen, mold, dust and animal dander. When a person with allergic rhinitis breathes in an allergen, their body reacts by releasing chemicals that lead to allergy symptoms. Allergic rhinitis may vary based on the time of year, since weather impacts the quantity of pollen in the air.

For example, on boiling, dry days there will be more pollen and allergens in the air. On cool, damp days allergens and pollen are washed to the ground.
When blood vessels in an individual’s nose expand, the nasal lining fills with blood and fluid, leading to nonallergic rhinitis.

Common allergens that cause allergic rhinitis include pollen (this type of allergic rhinitis is known as hay fever), as well as mould spores, home dust mites, and flakes of skin or droplets of urine or saliva from certain animals.
