What causes dryness and itching in the nose?

Nasal dryness and itching may be caused by environmental irritation, bad habits, atrophic rhinitis, allergic rhinitis, or vestibulitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a healthcare professional. Specific analyses are as follows:

1. Environmental irritation: Prolonged exposure to dry or cold environments may cause the nasal mucosa to lose moisture, leading to dryness and itching. It is advisable to avoid extended exposure to extreme weather conditions and drink plenty of warm water to help relieve discomfort.

2. Bad habits: Frequent nose picking or forceful nose blowing may damage the nasal mucosa, making it dry and sensitive. These behaviors should be avoided. Instead, gentle cleaning methods such as saline nasal irrigation can be used.

3. Atrophic rhinitis: This condition may be associated with long-term inhalation of dry air or exposure to harmful chemical substances. Insufficient moisture in the nasal cavity may lead to symptoms such as nasal dryness, itching, and nosebleeds. Patients are advised to follow medical instructions when using medications such as vitamin A capsules, Rhinitis康 tablets, and erythromycin ointment.

4. Allergic rhinitis: This may occur due to exposure to allergens such as pollen or dust mites. Contact with these substances triggers an overreaction of the immune system, causing the aforementioned symptoms, possibly accompanied by redness, swelling, and pain. Patients should follow medical advice when using medications such as fluticasone propionate nasal spray, cetirizine hydrochloride oral solution, or budesonide nasal spray.

5. Nasal vestibulitis: This may result from bacterial infection or allergic reactions affecting the skin of the nasal vestibule. Local inflammation typically presents as dryness, redness, and swelling of the skin in the nasal vestibule, along with itching. Patients should use medications such as zinc oxide ointment, erythromycin ointment, or mupirocin ointment under medical supervision to improve symptoms.

In daily life, patients are encouraged to drink plenty of warm water, avoid spicy foods such as chili peppers and Sichuan pepper, and consume fresh vegetables and fruits like radishes, cabbage, and kiwifruit in moderation.
