Hello and welcome to Dr. Mercola's cellular wisdom. I'm Ethan Foster. Today we're decoding dry,

wet, tickly, and chronic coughs so you can act on the right signals at the right time

instead of masking symptoms and missing what your airways are asking you to address.

I'm Alara Sky. You'll hear how pollution, smoke, and chemical exposure accelerate lung aging

when a cough means you need immediate care, why chronic coughs over eight weeks demand evaluation,

and how specific research-backed steps, like nebulized hydrogen peroxide, raw honey, steam, and hydration,

can support recovery when used correctly and early.

Let's start with the role a cough plays.

You generate a powerful burst of air, about 50 miles per hour,

because sensors in your airways detect irritants and tell your brain to clear them.

That reflex protects you. The goal isn't to silence every cough, but to understand what type

you have so you respond appropriately. A dry cough often follows a viral infection or exposure

to dust and pollution. A tickly cough feels like an itch in your throat and commonly reflects irritation or

allergies. Chesty or wet coughs produce phlegm as you clear infection or post-nasal drip.

When a cough lingers beyond eight weeks, you treat it as a red flag for deeper issues.

You should seek medical attention sooner if you notice blood-streaked sputum, chest discomfort,

shortness of breath, or unexplained weight loss.

Those patterns can accompany asthma, chronic bronchitis, reflux, or even early lung cancer.
