What are the types of allergic rhinitis?
Seasonal, which occur mainly during pollen seasons. Particularly bad Ohio allergens include Canadian goldenrod and carnations. Blooming trees, grass, and weeds also release pollen. With blooms occurring earlier and more pollen in the air, it is increasingly hard for allergy-sufferers to breathe easy in Ohio.
Perennial, which occur year round. Common allergens are mold, animal dander and dust mites.
