Post-Nasal Drip: Why Mucus Feels Stuck in Your Throat

That constant need to clear your throat, the tickle that sets off a cough, the feeling of something sitting just behind your tongue — for a lot of people, the source isn't the chest at all. It's post-nasal drip.

What's actually happening

Your nose and sinuses produce mucus all day. Normally it drains down the back of the throat and you swallow it without noticing. Post-nasal drip is simply when you do notice — because there's more of it, it's thicker than usual, or both.

Common causes

• Allergies — pollen, dust mites, pet dander and mould can all ramp up nasal mucus.
• Colds and sinus infections — often leave drip behind for a week or two after other symptoms fade.
• Dry air — thickens mucus so it drags rather than flows.
• Weather and temperature changes — cold air can trigger a runny nose in some people.
• Reflux — stomach acid irritating the throat can mimic or worsen drip.

Why mornings and nights are worst

Lying down lets drainage pool at the back of the throat, and you swallow far less while asleep. That's why the sensation often peaks at bedtime and on waking.

When to get it checked

If drip lasts more than a few weeks, comes with facial pain and fever, or you notice blood, see a doctor. Long-lasting drip with itchy eyes and sneezing may be allergies, which are very treatable.

A daily botanical routine like BreathiZen® can be part of how you look after your airways, but it isn't an allergy or sinus treatment — those need their own care.
