Seasonal allergies usually occur in spring or when there is sudden change in climactic condition, extreme cold. The most common type of seasonal allergy is allergic rhinitis (hay fever), in which a person suffers from irritation and inflammation of the nasal passages.

Allergy is an exaggerated response of the oversensitive immune system to certain external influences called as allergens. These allergens are actually responsible for an allergic reaction, while in many individuals with strong immunity, they don’t create any problem.
The allergens that cause an allergic reaction are pollen, dust, dust mites, pet dander, environmental pollutants, sudden climatic changes, certain air-borne viruses and molds. The symptoms of allergic rhinitis are frequent sneezing, nasal congestion, runny nose, red/itchy eyes, cough and headache.
