NASAL ALLERGY IS WHEN THE NOSE over-reacts or over-responds to certain stimuli, usually triggered by an allergen.
Common allergens are dust mites, animal danger, pollen, mold and certain foods.
The nose has turbinates – fleshy swellings, filled with blood vessels, which act like filterson the lateral walls of the
nasal passages. The entire surface of the turbinates is covered with glands that secrete mucous. Various stimuli and
allergens change the flow of blood through these turbinates, causing them to swell or shrink in size, and to increase
and decrease mucous production. With these turbinates, the nose can humidify, warm and regulate the air flowing through
the nasal passages. The nose also has nerve endings that can cause a reflex sneezing to expel unwanted substances or
However, when the nose is over-stimulated or allergic, it may lead to symptoms of allergic rhinitis, including:
Puffiness and dark-circles around the eyes
Puffiness of the nose
Loss of sense of smell

range of pollen and grass allergens all year round, unlike countries with seasonal changes.
