I keep having an awful itch in my nose whenever im tired, it can happen anytime during the day but always when im tired.. what causes this? and what can i do against it?

There are several possible causes of an itchy nose, including allergies, dryness, and irritants. However, the fact that the itching occurs specifically when you are tired suggests that it may be related to fatigue. Perhaps when we are tired, your immune system becomes weaker, making us more susceptible to allergens and irritants. This can cause the nasal passages to become inflamed and itchy.
