Making sense of allergies

An introduction to allergies and how they affect your life

An allergy is the response of your body’s immune system to harmless substances (called allergens) such as dust and mould. This results in an overproduction of a chemical known as histamine that causes symptoms such as runny nose, sneezing, itchy eyes and rashes. Symptoms can range from minor discomfort to severely affecting the performance and productivity at work or school.

Common allergies include seasonal/intermittent allergic rhinitis, perennial/persistent allergic rhinitis, asthma, and urticaria when the allergen attacks the skin.
