What is pollen and what is it made of?
Pollen is made up of tiny grains that are essential to plant fertilization. Plants that have fine, powdery pollen are the main culprits for allergies. Each season has its own peak pollen sources with trees in the early spring, grass in late spring and early summer and weed pollen in the late summer and early fall.
What is mold?
Mold can be found virtually everywhere, including indoors and outdoors. Mold has spores that are airborne and thrives in damp locations. Everyone breathes in mold spores each day, but only those who are allergic will experience any type of reaction.
What are dust mites?
Close relatives of ticks and spiders, dust mites are tiny bugs that live in dust. They love warm, humid environments and feed on skin cells shed by people. Dust mites tend to make their homes in bedding, upholstered furniture and carpet. Frequent sneezing and a runny nose might be a sign of a dust mite allergy.
