What causes dry nose and sore throat?

Dry nose and sore throat are commonly caused by dry weather, colds, nasopharyngitis, pharyngitis, or chronic bronchitis. It is recommended to seek medical evaluation and use medications as directed by a healthcare provider. Specific causes are analyzed as follows:

1. Dry weather: When environmental humidity is low, especially in arid climates, the mucous membranes of the nasal passages and throat can be easily affected. Dry air may cause these membranes to lose moisture, leading to dryness and fragility. This can be alleviated by drinking more warm water.

2. Cold: A cold is a respiratory infection caused by viruses, often accompanied by symptoms such as nasal congestion, runny nose, and sore throat. During a cold, viral invasion causes inflammation and swelling of the mucous membranes in the nose and throat, resulting in dryness and pain. It is recommended to follow medical advice and use antiviral oral liquids, Lianhua Qingwen capsules, Ganmao Ling granules, or similar medications to relieve symptoms.

3. Nasopharyngitis: Nasopharyngitis refers to inflammation of the mucous membrane in the nasopharynx, usually caused by bacterial or viral infections. Inflammation leads to congestion and swelling of the mucosa, causing symptoms such as nasal congestion, runny nose, and sore throat, which may result in a dry nose and painful throat. Treatment may include amoxicillin capsules, compound Honeysuckle granules, roxithromycin tablets, or other medications under a doctor's guidance.

4. Pharyngitis: Pharyngitis is inflammation of the mucous membrane in the throat, typically caused by bacterial or viral infections. Common symptoms include throat pain, dry cough, and sputum production, leading to a dry and painful sensation in the throat. Medications such as Yinhuang lozenges, Shufeng Jiedu capsules, or prednisone acetate tablets may be used as directed by a physician to alleviate symptoms.

5. Chronic bronchitis: Chronic bronchitis is a chronic respiratory inflammation characterized by airway mucosal inflammation and increased mucus secretion. This inflammation may affect the mucous membranes of the upper respiratory tract, including the throat and nasal passages, causing dryness and discomfort. Under medical supervision, medications such as roxithromycin capsules, penicillin V potassium tablets, or ribavirin granules may help relieve symptoms.

In daily life, maintaining a light diet, regular sleep schedule, and moderate exercise are recommended to support recovery.
