Hay fever

Hay fever is caused by pollen allergy and is classified as a type of allergic rhinitis. Typical symptoms include itching, runny nose, irritated eyes and sneezing. The same symptoms can also occur in seasons when pollen concentrations are low, but large quantities of other particles are present in the air, such as mold, exhaust gases, etc.
