substance. When a child suffering from allergy comes into contact with these
substances, known as an allergen — either by touching, breathing, eating,
or having it injected, it acts as a triggering agent, which excites the immune
system to release histamines and other chemicals as a reaction. These chemicals
irritate the body and cause symptoms such as runny nose, sneezing, itching,
and coughing etc
Allergens: The most
common allergens are: dust, woolens, molds, pollens,
animal dander, perfumes, various foods like shellfish,
peanuts, eggs, milk, wheat etc.
