Why do my eyes swell up with hay fever?
When you have hay fever, your body reacts to pollen or other allergens by releasing chemicals like histamine. This response can cause inflammation and swelling in various parts of your body, including your eyes. The swelling is part of your immune system's attempt to protect you from what it sees as harmful substances.
Key points:
- Allergens trigger an immune response.
- Histamine release causes inflammation.
- Swelling can affect the eyes specifically.
- This reaction is common during allergy season.
