What is Allergy?

02 July 2010

Allergies occur when your body’s immune system reacts to substances in the environment that do not bother most people. These substances are known as allergens.

If you are exposed to an allergen that you are sensitive to, you can develop an allergic reaction that leads to redness and swelling, which can be irritating or uncomfortable.

Allergic reactions can affect your:

  • Nose and/or eyes – hay fever (allergic rhinitis and/ or conjunctivitis)
  • Skin – eczema or hives
  • Lungs – asthma

How can allergies be minimised?

Australia has one of the highest incidences of allergy in the world. Although we don’t yet know the reason, whatever it is, allergies can make life rather miserable for millions of Australians – particularly in certain periods of the year like spring.

Allergies occur when our immune system reacts to substances, known as ‘allergens’. This can affect the nose and eyes with hayfever; the skin with conditions such as eczema or hives; or the lungs with asthma. Obviously the best way to manage allergy is to avoid the allergens – but that’s easier said than done!

Allergens and asthma triggers are all around us… pollens from grass and weeds, cigarette smoke, or chemicals in cleaners, and other household products.
