Question 3 Answer
Fact!
"Hay fever" is a commonly used term for
seasonal allergic rhinitis, which can produce such symptoms as runny nose, itchy
eyes and throat, uncontrollable sneezing, and sometimes itching of the skin.
Some people have an over-active immune system which identifies normally harmless
particles, such as pollens or animal dander, as dangerous. This causes an
excessive reaction that actually causes inflammation -- an allergy. The
substances causing it are allergens.
