What causes dryness inside the nose?

Dryness inside the nose is usually caused by dry environments, air pollution, internal heat ("shang huo"), atrophic rhinitis, or dry rhinitis. If discomfort arises from any of the above conditions, medical attention should be sought promptly to prevent worsening symptoms. Specific explanations are as follows:

1. Dry environment: Prolonged exposure to dry environments—especially during dry seasons or in arid regions—can lead to low humidity in the air, causing the nasal mucosa to lose moisture and resulting in nasal dryness. Using a humidifier indoors or increasing indoor humidity can help relieve nasal dryness.

2. Air pollution: Long-term exposure to pollutants such as smoke, chemical fumes, or dust may irritate the nasal mucosa, leading to sensations of dryness and discomfort. It is recommended to avoid staying in polluted environments for extended periods.

3. Internal heat ("Shang huo"): According to Traditional Chinese Medicine (TCM), "shang huo" refers to excessive internal heat. This condition may impair blood circulation in the nasal mucosa and reduce its function, leading to a dry sensation in the nose. Under medical guidance, medications such as Niuhuang Qingfei Tablets, Yinxu Weitong Granules, or Longdan Xiegan Decoction may be used for regulation.

4. Atrophic rhinitis: This is a chronic form of rhinitis characterized by severe thinning and atrophy of the nasal mucosa. In such cases, the nasal mucosa may lose its normal ability to stay moist, resulting in dryness inside the nose. Under a doctor's supervision, medications such as Tongqiao Biyan Granules, Biyan Tablets, or Qianbai Biyan Tablets may be used to alleviate inflammation.

5. Dry rhinitis: Dry rhinitis is a condition in which the nasal mucosa remains chronically dry. The dry mucosa is prone to damage and inflammation, further intensifying the sensation of dryness. Under medical guidance, medications such as Xiangju Capsules, Amoxicillin Capsules, or Biyuan Tongqiao Granules may be used to relieve discomfort.

In daily life, it is recommended to maintain a balanced diet and consume more foods rich in water and vitamins, which can help prevent or alleviate nasal discomfort.
