One reason why whooping cough is more severe at night is due to the dry air indoors which irritates, and another reason is due to changes in body posture. As the body is in a supine or lateral position during sleep at night, the bronchial mucous secretion cannot be expelled from the body, which stimulates the bronchial nerves and induces symptoms such as coughing. The typical cough is a paroxysmal spasmodic cough, and it can also lead to red face, runny nose, and in severe cases, nasal discharge, tears, nausea, and vomiting. It is necessary to receive timely anti-inflammatory treatment and maintain the cleanliness of the indoor air.
