Seasonal allergies are caused by weather changes and the increase of pollen in the air. Seasonal allergic rhinitis is often caused by tree pollen in the early spring. Grass pollen is often the cause for seasonal allergies during the late spring and early summer months. Late summer and fall usher in seasonal allergy symptoms due to weed pollen. Seasonal allergies are more commonly known as hay fever. Seasonal allergy symptoms appear when the immune system treats typically harmless substances as a danger to the body and releases chemicals into the bloodstream to fight off the seemingly dangerous substance. The body’s reaction to substances can change over time. Seasonal allergies are less common during the winter, but you may have a response to indoor allergens, such as mold, dust mites, and pet dander.
Common symptoms of seasonal allergies include but are not limited to:
Running or stuffy nose
Watery Itchy eyes
Itchy sinuses, throat, or ear canals
Shortness of breath
