What causes a dry and sore throat upon waking in the morning?

Generally, waking up in the morning with a dry and sore throat may be caused by mouth breathing during sleep, dry indoor air, acute pharyngitis, acute tonsillitis, or reflux laryngitis. It is recommended to seek medical attention promptly to identify the underlying cause and receive appropriate treatment under a doctor's guidance. Specific analyses are as follows:

1. Mouth breathing at night: Nasal congestion or improper sleeping posture can lead to mouth breathing, causing rapid moisture loss from the oral cavity and dryness of the throat mucosa, resulting in pain. Adjusting sleeping posture—preferably side-lying—and addressing significant nasal congestion by evaluating for rhinitis are recommended. Practicing closed-mouth deep nasal breathing before sleep may also help.

2. Dry indoor air: Low humidity in enclosed rooms overnight leads to evaporation of moisture from the throat mucosa, causing dryness and pain upon waking. Using a humidifier in the bedroom before sleep, maintaining humidity levels between 50% and 60%, drinking a cup of lukewarm water before bed, and placing a glass of water near the bedside can help maintain air moisture.

3. Acute pharyngitis: Viral or bacterial infections cause congestion and swelling of the pharyngeal mucosa, leading to noticeable dryness and pain in the morning, often accompanied by a burning sensation in the throat. Patients may use medications such as Lanqin Oral Liquid, Cefuroxime Axetil Tablets, or Compound Borax Gargle Solution under medical supervision.

4. Acute tonsillitis: Infection and inflammation of the tonsils cause throat dryness and pain, often accompanied by difficulty swallowing and swollen tonsils. Medications such as Amoxicillin Capsules, Pudilan Anti-inflammatory Oral Liquid, or Compound Chlorhexidine Gargle Solution may be used under medical guidance.

5. Reflux laryngitis: When lying flat at night, gastric acid may reflux into the throat, irritating the mucosa and causing dryness and pain, often accompanied by acid regurgitation and heartburn. Patients may take medications such as Omeprazole Enteric-coated Capsules, Domperidone Tablets, or Hydrotalcite Chewable Tablets under medical advice. In severe cases, laparoscopic fundoplication surgery may be considered to prevent acid reflux and protect the throat mucosa.

In daily life, avoid spicy and excessively hot foods, and consume more throat-soothing fruits and vegetables such as pears and white fungus. Develop the habit of rinsing the mouth after meals to maintain oral hygiene. Avoid overusing the voice, reduce late-night activities, and strengthen overall immunity to prevent throat discomfort.
