Is it normal to never cough?
Depends.It depends
If you just rarely get sick or irritated airways, going a long time without coughing can be normal. If you truly can’t cough when something goes down the wrong way, or you have trouble swallowing, that’s worth getting checked.
Some people hardly ever cough because they don’t often get colds, allergies, or airway irritation. You don’t need to cough regularly for your body to be working normally.
Coughing is also a protective reflex, though. If you can’t cough when you choke or swallow something the wrong way—or you’re having swallowing or breathing problems—check in with a healthcare professional.
