Causes of Allergic Rhinitis
How did you get that cold again?
The troublesome bout of allergic rhinitis (nasal allergy) which a lot of people dread can be triggered by a number of allergens. Allergens are substances that can induce an ‘allergic reaction’ in the body.
Some of the allergens that are common culprits in cases of allergic rhinitis (nasal allergy):
- Outdoor molds
- House dust mites
- Wood dust
- Exposure to certain animals (including pets)
- Irritant triggers such as smoke, pollution, and strong smells
When a susceptible person is exposed to an allergen such as pollen or dust, the body releases certain chemicals which include ‘histamine’. Histamine release is responsible for allergy symptoms such as itchy feeling, swelling, and mucus production.
Apart from allergens, there are certain other factors that are responsible in the development of allergic rhinitis (nasal allergy):
Weather: Hot, dry, windy days are more likely to trigger an allergy attack (due to increased amounts of pollen in the air) as compared to cool, damp, rainy days (when most pollen is washed to the ground)
Genetics: Heredity seems to play an important role in allergic diseases. If both your parents suffer from allergic rhinitis (nasal allergy), you have almost 50% chances of developing the same. If one of your parents suffers from it, your chances of developing this stand at 30%.
It must also be noted that the triggers of an attack may vary from person to person and the patient himself has to figure out which of these causative factors precipitates the episodes in him.
