Introduction

In general, persistent coughing before sleep may be caused by environmental irritants, cough-variant asthma, chronic bronchitis, chronic pharyngitis, or gastroesophageal reflux. During nighttime sleep, the lower ambient temperature may cause patients to inhale large amounts of cold air, which can irritate the respiratory tract and trigger coughing. It is recommended that patients take proper warming measures; symptoms usually resolve spontaneously.

Generally, persistent coughing before sleep may be caused by environmental irritants, cough-variant asthma, chronic bronchitis, chronic pharyngitis, gastroesophageal reflux, and other factors. A detailed analysis is as follows:

1. Environmental Irritants

During nighttime sleep, the temperature is relatively low. Inhaling large amounts of cold air may irritate the respiratory tract and trigger coughing. It is recommended that patients take proper warming measures; symptoms usually resolve on their own.

2. Cough-Variant Asthma

At night, the vagus nerve in the human body tends to be in an excited state, which may cause bronchial smooth muscle contraction and increased respiratory secretions, potentially leading to severe coughing. Patients can use medications such as formoterol fumarate tablets or salbutamol inhalation aerosol under medical guidance, which are effective for treatment.

3. Chronic Bronchitis

If a patient experiences coughing before sleep, chronic bronchitis should be considered first. Chronic bronchitis is often accompanied by symptoms such as sputum production and wheezing. Under a doctor's guidance, patients may take appropriate doses of drugs like carbocisteine tablets or bronchitis tablets to alleviate symptoms.

4. Chronic Pharyngitis

Patients with chronic pharyngitis may also experience coughing before bedtime. This condition can also cause a sensation of a foreign body in the throat or a burning feeling. Under medical advice, patients may use medications such as Pudilan Anti-inflammatory Oral Liquid or Jinshang Liyan Granules for treatment.

5. Gastroesophageal Reflux

If a patient frequently feels the urge to cough before sleep, gastroesophageal reflux should also be considered. When lying down, stomach contents may flow back up through the esophagus and reach the throat, triggering coughing. Under medical supervision, patients can take medications that suppress gastric acid and protect the gastric mucosa, such as omeprazole enteric-coated capsules or lansoprazole enteric-coated tablets.

In addition, persistent coughing before sleep could also be due to conditions such as pneumonia or bronchiectasis. It is recommended that patients identify the exact underlying cause before initiating appropriate treatment to avoid delaying recovery.

What causes constant coughing and shortness of breath?

Persistent coughing with shortness of breath may be caused by chronic bronchitis resulting from factors such as increased environmental pollution, frequent smoking, or pathogen infection. It could also result from climate changes, combined with poor air quality, inadequate ventilation, and excessive exposure to microorganisms, leading to respiratory infections such as bronchopneumonia. Often, it is caused by infection with the novel coronavirus, resulting in COVID-19.

What should I do if I have a cold, an itchy throat, and persistent coughing?

A sore throat with persistent coughing after catching a cold may be caused by improper diet, acute pharyngitis, allergies, bronchitis, pneumonia, or other factors. Patients can receive symptomatic treatment based on the specific cause. It should be noted that if throat itching and coughing persist for a long time, or are accompanied by other severe symptoms such as high fever or rapid breathing, it is recommended to seek medical attention as early as possible to avoid serious complications.
