Hayfever, also known as Allergic Rhinitis, is an allergic response to pollen, dust, animal dander or mould.
Hayfever is caused by the body’s response to a perceived threat (allergen) or in this case pollen. When the pollen is inhaled by a person with a more sensitive immune system, a response known as the inflammation cascade is triggered. This is what causes all of the unpleasant symptoms as our defences do everything they can to expel the threat from our body.
Your body’s natural response to fight off invaders (in this case pollen) that it sees as threatening. Antibodies (our defence cells) are released to attack the invading pollen. Some of our own cells are damaged during this “war” and they release a variety of chemicals, one of which is Histamine. These are very irritating and are what cause the symptoms of Hayfever.
