Dr. Sanderson shares if it is harmful to the lungs if one swallows mucus.
No, it’s not harmful. Mucus is a normal product of our respiratory epithelium and that mucus comes up and we sometimes will cough it out, sometimes swallow it, but it does not harm. It’s a normal body product and is not in any way harmful.
