What happens if you swallow phelgm from a cold?

Answer 1

Swallowing phlegm during a cold is generally harmless, as the stomach's acidic environment can neutralize pathogens and mucus. The body produces phlegm to trap and expel irritants, so swallowing it may actually help clear your throat and sinuses. However, if you find the taste or texture unpleasant, it's better to spit it out. If you're experiencing severe symptoms, consult a healthcare professional.
