Allergies and Hay Fever

Immune System

An allergic response is a defence against infection where there is no danger; an over-reaction by the body's defence mechanisms to certain food, clothing, pollen and other materials.

An allergy can manifest itself as asthma, eczema, hyperactivity, fatigue, itching, runny nose, sneezing, headaches, lumps and bumps.

Hay fever is a relatively mild, although very uncomfortable, form of allergic reaction. Treatment of hay fever should begin at least half a year before the onset of allergy season.

Mild to moderate allergic reactions may manifest in a variety of ways, from mild headaches or digestive disturbances, to itchy, blotchy skin rashes. Severe allergic reactions, called anaphylactic shock cause swelling of the airways. In very severe cases, the airway can become completely blocked, causing respiratory arrest.
