The inability to effectively expel mucus and other respiratory secretions when the mouth is covered is a recurring concern voiced within online forums. Individuals describe experiencing a suppressed or less forceful cough when attempting to stifle the sound by covering the mouth, hindering the expulsion of phlegm. This presents a challenge as covering the mouth is often a social norm aimed at preventing the spread of germs.
Efficient clearance of the airways is crucial for maintaining respiratory health. A productive cough helps to remove irritants, pathogens, and excess mucus from the lungs, preventing infections and facilitating easier breathing. The historical context of etiquette dictates covering the mouth during a cough to limit the spread of disease. However, the reported difficulty in achieving a productive cough when adhering to this practice necessitates an examination of the underlying mechanisms involved.
