2. Bronchial asthma: high vagus nerve excitability at night leads to airway spasm, which may induce coughing, while waking up is favorable for coughing up phlegm, accompanied by wheezing, chest tightness, coughing, coughing up phlegm and so on.
3. Chronic Obstructive Pulmonary Disease (COPD): Chronic coughing or sputum coughing with dyspnea or wheezing may occur. When stimulated by poor indoor air quality and open-mouth breathing at night, it can lead to increased airway sensitivity, phlegm accumulation and irritation of the throat, while waking up facilitates phlegm coughing, which may lead to sleep cough.
4. Gastroesophageal reflux: due to gastric acid, bile reflux, lying down at night may stimulate the pharynx, resulting in this phenomenon, but also can be seen in the stomach burning sensation or epigastric pain, as well as nausea, dysphagia and so on.
