Most of the causes of a strong cough from 12:00 am to 3:00 am are related to airway hyperresponsiveness, such as variant asthma and poor indoor air circulation.
For most patients, in the early hours of the morning, because of airway hyperresponsiveness, resulting in coughing symptoms, and the common cause of variant asthma, because the vagus nerve is more excited at night, so it will cause patients with bronchial smooth muscle spasm, affecting the bronchial diastole, which can cause patients with coughing symptoms.
Of course, if the patient’s indoor air is not fluent or the air is dry, it may also affect the respiration, thus producing irritating cough symptoms.
Coughing at 12:00 a.m. to 3:00 a.m. may also be due to respiratory infectious diseases, heart failure, etc. It is recommended that the patient can go to the respiratory department of the hospital, cooperate with the doctor to complete the relevant examinations, according to the results of the examination, and actively cooperate with the doctor’s treatment.
