Why is it so difficult to suppress a cough?

In: Biology

Because it’s your bodies way of clearing your air pipe, you kinda need that thing clear so you can breathe

The cough reflex is a protective mechanism to rid the lungs of something that should not be there. If so, not expectorating can lead to serious consequences. And this is an involuntary mechanism, which you have no control over.

But if is just a minimal amount of expectorant, then you can voluntarily suppress it.
