What is hay fever?

The start of spring is often synonymous with the appearance of hay fever and you may have already started feeling the first signs. Also known as seasonal allergic rhinitis, it’s caused by exposure to certain pollen in the air. Hay fever affects over 15% of the population according to New Scientist magazine, and incidence has reached as high as 30% among adults in the UK. Furthermore, it seems to be becoming more and more common, due to factors like global warming and atmospheric pollution which are increasing pollen concentration.
