Introduction
Coughing at night but not during the day may be related to physiological factors, or could result from pathological causes such as allergic cough or chronic bronchitis. It is recommended to immediately visit a hospital for diagnosis and, based on the specific condition, receive appropriate medication and treatment. It might also be associated with conditions like bronchial asthma. During an episode, ensure adequate rest, maintain a proper daily diet, and avoid consuming spicy foods.

It is recommended to seek immediate medical evaluation and diagnosis at a hospital, followed by medication and treatment based on the specific condition.
I. Physiological Factors
For example, lying in a supine position at night may elevate the abdomen and diaphragm, restricting lung movement and leading to symptoms such as coughing and shortness of breath. Symptoms usually improve by adjusting sleeping posture, and no special treatment is required.
II. Pathological Factors
1. Allergic Cough
During cold winter months, nighttime temperatures drop. Inhaling large amounts of cold air during sleep can easily irritate the upper respiratory tract, causing coughing and breathing difficulties. Under a doctor's guidance, patients may take medications such as loratadine tablets, chlorpheniramine maleate tablets, or cetirizine hydrochloride tablets to alleviate these symptoms.
2. Chronic Bronchitis
Due to chronic inflammation of the bronchi, bronchial secretions significantly increase at night and cannot be cleared promptly. Changing body positions may cause these secretions to stimulate the bronchial smooth muscles, resulting in coughing and sputum production. During illness, follow medical advice to use medications such as compound licorice ammonium chloride tablets, levofloxacin hydrochloride capsules, or aminophylline injection. Additionally, maintain good indoor hygiene.
Other conditions such as bronchial asthma may also be involved. During illness, ensure adequate rest, maintain a proper daily diet, and avoid spicy foods.
