A nose that starts dripping on a chilly walk doesn’t automatically mean you’re coming down with something. Cold air itself can trigger extra mucus, even when you otherwise feel well.
Key takeaways
- Cold, dry air can make your nose produce more mucus to keep its lining moist.
- A scarf over your nose and mouth helps warm the air you breathe outdoors.
- Saline rinsing can help with lingering mucus and nasal dryness; it isn’t a way to switch off your nose’s response to cold air.
Why does cold air make your nose run?
Cold, dry air irritates the lining of your nose, prompting its glands to make extra mucus to keep that lining moist. Your nose also warms and moistens incoming air before it reaches your lungs. That extra moisture can leave you with a watery drip, even without a cold or allergies.
Temperature changes can also trigger nonallergic rhinitis, which means a runny or stuffy nose caused by something other than an allergy.
Itchy eyes and repeated sneezing may point toward allergies, while a sore throat, fever or feeling unwell suggests there may be more going on than a reaction to cold air. Symptoms can overlap, so the weather alone doesn’t tell you the cause.
What helps while you’re outdoors?
Try covering your nose and mouth with a scarf to warm the air before you breathe it in.
Gently blow your nose when needed, and notice whether the dripping continues once you’re back indoors.
If frequent dripping is disrupting your day, ask your clinician about treatment for a persistently runny nose. Tell them whether it happens only in the cold or continues indoors, so they can help work out what’s triggering it.
Where does a saline rinse fit?
A saline rinse adds moisture and washes away mucus and irritants, making it useful when your nose feels dry or clogged after being outdoors. Saline nasal irrigation can help ease nonallergic nasal symptoms, but rinsing before a walk doesn’t guarantee your nose will stay drip-free in the cold.
For example, if your nose drips during a cold morning walk but feels comfortable when you get home, an extra rinse may not be needed. If you’re left with mucus that feels stuck or a dry nose, try a saline rinse according to your irrigator’s directions and notice whether it leaves your nose more comfortable.
Mix saline with distilled, sterile or previously boiled and cooled water, following the saline product’s amounts. Untreated tap water can introduce germs into your nose, even when it’s safe to drink. Use a lukewarm solution, follow your model’s rinsing and cleaning directions, and let the irrigator dry after use.
If cold-weather outings leave your nose dry or clogged with mucus, explore the SinuPulse Elite nasal irrigation system for your rinse at home. Its adjustable pressure lets you control the flow for comfort as you rinse away lingering mucus and moisten your nasal passages.
