Hay fever is an allergic disorder characterized by an exaggerated immune response to pollen grains and other
substances. Also known as allergic rhinitis, there are two types: seasonal, which occurs only during the time of year
in which certain plants pollinate, and perennial, which occurs all year round.
(A related problem, nonallergic rhinitis, shares symptoms with hay fever but is not typically caused by proteins like hay
fever and allergies are.)Typically, if you suffer from hay fever in the spring, you’re probably allergic to tree pollens.
Grass and pollens may be causing your allergic reaction during the summer
