What causes a sore throat and cough at night?

Generally speaking, the throat refers to the pharynx. Nighttime throat itching and coughing may be related to dry air, mouth breathing, allergic cough, acute upper respiratory tract infection, or sinusitis. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

1. Dry Air

In dry environments, the mucous membrane of the throat easily loses moisture, leading to dryness, itching, sore throat, and dry cough. To relieve these symptoms, a humidifier can be used indoors to maintain moist air, and adequate water intake should be ensured, especially drinking an appropriate amount of water before bedtime.

2. Mouth Breathing

When breathing through the mouth during sleep, moisture from the oral mucous membrane evaporates, causing dryness and irritation of the throat. Adjusting sleeping posture, such as elevating the head with a pillow or using a humidifier, may help alleviate this condition.

3. Allergic Cough

Allergic cough may be related to genetic and environmental factors. When patients come into contact with allergens such as cold air or pollen, the respiratory tract may become irritated, leading to nocturnal irritative dry cough. Symptoms such as sore throat and itching may also occur. Medications such as Yinhuang Tablets, Cefixime Dispersible Tablets, or Cetylpyridinium Iodide Lozenges may be used under a doctor's guidance.

4. Acute Upper Respiratory Tract Infection

Acute upper respiratory tract infection is usually caused by chilling, decreased immunity, and other factors. Changes in body position at night may cause increased upper respiratory secretions that irritate the throat, resulting in coughing. Symptoms such as phlegm production and sore throat commonly accompany this condition. Medications such as Compound Paracetamol and Amantadine Tablets, Azithromycin Tablets, or Isatis Root Granules may be used under a doctor's guidance.

5. Sinusitis

Sinusitis may be caused by nasal diseases, environmental factors, or unhealthy lifestyle habits. Patients may have excessive secretions in the sinuses, which may flow into the throat when lying down, irritating the throat and causing coughing. Symptoms such as dizziness and headache are commonly associated. Medications such as Tongqiao Biyan Tablets, Biyuanshu Oral Liquid, or Amoxicillin Capsules may be taken as directed by a physician.

In daily life, it is advisable to eat more foods rich in vitamins and minerals, such as fresh vegetables and fruits, to enhance immune function. Additionally, appropriate intake of protein, moderate exercise, and avoiding late nights can help maintain overall health.
