Children coughing in the middle of the night may be related to the common cold, allergies, gastroesophageal reflux and so on. 1. Common cold: If a child gets cold during the day and develops a common cold, the respiratory secretions will be more. When sleeping at night, due to the body position, the respiratory secretion is easy to be retained in the throat, causing irritation to the throat, so it is easy to cough in the middle of the night. 2. Allergy: children’s airway sensitivity is high, at night because the windows and doors are closed, the air does not circulate. If there are more allergic substances such as dust mites, it will cause irritation to the airway and cough with high airway sensitivity. 3. Gastroesophageal reflux (GERD): Perhaps the child himself suffers from GERD. When the night due to the flat lying position when the stomach contents are easy to reflux to the pharynx, stimulate the child to appear in the middle of the night cough. Children cough in the middle of the night can also be seen in other reasons, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for relevant examinations, with the help of the doctor to clarify the cause, and targeted treatment or treatment.
