Australia has relatively clean air but one of the highest rates of allergies in the world.

Sun, surf, and a healthy outdoor lifestyle full of the very best modern opportunities. This is the picture postcard view of Australia that has attracted so many different cultures to our shores for generations.
But the same environment that makes our country such a great place to live has also created the perfect conditions for a rise in allergic diseases such as hay fever, as a variety of local nighty triggers interact with our changing biological makeup. We have constructed the perfect scenario for the expression of our allergic tendencies, says allergy expert and National Asthma Council Australia spokeswoman Sheryl van Nunen.
An allergy in general is an anti-parasite defence that has gone slightly wrong, so the immune system is not working for us but against. The immune system is pretty gung-ho and this is just a misfire. You can be allergic but without the right environment you wont express.
Allergies happen when the body becomes hypersensitive to substances known as allergens that would otherwise be harmless. When we breathe in, our nose acts as a filter to catch dust and microscopic particles on the tiny hairs and mucus inside. For those with an allergic immune system, when these dangerous allergens are caught, the body releases chemicals such as histamine to try to get rid of them.

This simple explainer shows what happens when we apply treatment and the science behind how treatments work to stop symptoms.

In general if you can be allergic that indicates a good immune system, Associate Professor van Nunen says.
