Why does my nose itch so much with hay fever?
Hay fever causes your nose to itch primarily due to an allergic reaction to pollen. When you inhale pollen, your immune system mistakenly identifies it as a harmful substance, leading to the release of chemicals like histamine. This release triggers itching and irritation in the nasal passages.
Key points:
- Allergic reactions to pollen are the main cause of itching.
- Histamine release from the immune system leads to nasal irritation.
- Environmental factors can worsen symptoms.
- Individual sensitivity to allergens varies greatly.
