The science behind the reaction...

Secondary research


The procedure of an allergic reaction
An allergic reaction happens when an allergen is is treated, by the body's immune system although a threat. It therefore reacts in a way to fight of the allergen, producing antibodies. The next time the body comes into contact with this allergen, the immune system remembers how it dealt with this, this causes a release of chemicals in the body which lead to an allergic reaction.


Cause of allergies?
Allergens are mostly harmless, and are common, for instance pollen in the air, a cat etc. What causes the reactions is our own immune system over reacting to a some what non-existent threat, resulting in our body giving a misguided assault.
