WHAT IS A COUGH?
When it comes to cold and flu symptoms, nothing is worse than having a bad cough. And while it’s easy to know when you’ve got one, you might be wondering: What is a cough exactly? A cough is a natural reflex your body produces to protect your lungs. Coughing helps clear your airways of lung irritants (like mucus), which can help stave off infections.
Coughs are never any fun, but what you may not realize is that there are different types of coughs. A cough can either be dry or wet (sometimes people refer to wet coughs as ‘chesty’), and either productive (one that produces mucus) or non-productive (one that does not produce mucus). Chesty coughs are usually productive while dry coughs are usually unproductive.
