Seasonal allergies are a body's abnormal response to triggers, so, instead of the trees, which really shouldn't bother you, but it causes a chemical response so the cells release these chemicals, like histamines. I'm sure you've heard of antihistamines, that cause symptoms, like runny nose, congestion, itchy eyes, itchy throat, those are some common symptoms that people have, and they can run in the spring and you may only have spring allergies, they can run in the fall, or they can, run year round if you have allergies to all of those environmental things. Or if you have dust allergies or molds – those tend to kind of be more year-round type, but the seasonal allergies are specific to trees, grasses or, like, ragweed in the fall.
