Seasonal allergens: This is a question best answered by a board certified allergist. However, common allergens may depend on the season. Trees in early spring, grass in spring and summer, ragweed in fall, dust and molds are usually all year long, but most common in the winter when baseboard heating is used. If you are symptomatic and an antihistamine is not effective, see an allergist.
