Question
Why do I still cough after a full night’s sleep? What’s going on?
Answer
Coughing is a protective response of the body, a kind of protective physiological phenomenon in babies. The human body can completely clear viruses, toxins, foreign bodies, or inflammatory secretions attached to the airways through coughing, including phlegm. If the cough is not severe, does not interfere with deep sleep or daily exercise, there is no fever, no rales in the lungs, and the mental state is good, then it’s nothing to worry about.
