What\'s it mean when your nose itches One possible explanation for an itchy nose is the presence of allergens in the environment. Allergens are substances that can cause an allergic reaction in some people, leading to symptoms such as itching, sneezing, and a runny nose. Common allergens that can cause an itchy nose include pollen, dust mites, and pet dander. When an allergen enters the nose, it can trigger the release of histamine, a chemical that is involved in the body's immune response. Histamine can cause the blood vessels in the nose to dilate and the nasal passages to swell, leading to an itchy or ticklish sensation. In addition to an itchy nose, histamine can also cause other symptoms such as itchy eyes, a sore throat, and coughing. Another possible cause of an itchy nose is dryness. When the nasal passages become dry, they can become irritated and inflamed, leading to an itchy or scratchy sensation. Dryness can be caused by a variety of factors, including low humidity, cold temperatures, and certain medications such as decongestants.
