Pollen: Pollen spread by trees and plants may cause hay fever and seasonal allergies. Annual hay fever mostly occurs in the spring and summer. Spring pollen is mainly tree based and less allergenic, while summer and fall pollen is mainly grass based and more allergenic. The main symptoms of hay fever include sneezing, runny nose, watery eyes, itchy nose, eyes and external ear canal, and in severe cases, hives, headache, and even bronchial asthma.
