What causes pollen allergies and why are they more common in spring? How does our body react?

Your Body's Allergic Reaction Has Nothing to Do With Pollen

Have you ever had allergy symptoms hit this suddenly? Pollen allergies happen when the immune system treats harmless pollen like a threat, triggering an IgE-mediated response and releasing histamine. This leads to symptoms like sneezing, runny nose, congestion, and itchy or watery eyes. Treatment focuses on controlling that response with antihistamines, nasal steroids, and in some cases immunotherapy, which can help reduce how strongly your body reacts over time.
