Blocked Nose and Snoring: How They're Linked and What to Try Before Bed
A cold or allergies block your nose, and suddenly you snore at night — a familiar story. The NHS lists blocked or narrowed nasal airways as a common cause of snoring. Here is how the two are linked and what you can try first.
Key points
- Blocked nasal airways are a common cause of snoring (NHS)
- A blocked nose leads to mouth breathing, which is also linked to snoring
- Address the cause of congestion: colds, allergies, dry air
- See a doctor if congestion lasts over 10 days or you have breathing pauses
Why does a blocked nose make you snore?
When your nose is blocked at night, you switch to breathing through your mouth. The NHS notes that blocked nasal airways, the mouth falling open and the tongue partly blocking the throat are common causes of snoring — and sleeping on your back, alcohol, smoking or extra weight can make it worse.
What to try before bed
- Sleep on your side: the NHS suggests a pillow or bed wedge to help.
- Avoid alcohol and smoking: both are linked to snoring.
- Reduce allergens: wash bedding often and keep the room ventilated with comfortable humidity.
- Check sleeping pills: the NHS says they can sometimes cause snoring — talk to your doctor.
For the causes of congestion itself, see our nasal congestion guide.
What a pharmacist or doctor may suggest
According to the NHS, a pharmacist may suggest sprays to reduce swelling inside the nose, chin straps to keep the mouth closed, or nasal strips. Ask a pharmacist or doctor whether they suit you — decongestant sprays should not be used long-term without advice.
When to see a doctor
- Congestion lasts over 10 days, keeps coming back or gets worse
- Breathing pauses, gasping or choking in your sleep
- Feeling tired all day or struggling to concentrate
- One-sided blockage, nosebleeds or facial pain
An ENT specialist is usually the first stop; if snoring comes with breathing pauses, a sleep study may be arranged.

FAQ
Will my snoring stop once my nose clears?
Not necessarily. Snoring has many causes — sleeping position, alcohol, weight and throat anatomy as well as congestion. If snoring continues, see a doctor.
Can hay fever make you snore?
When allergies block your nose, you tend to breathe through your mouth at night, and the NHS lists blocked nasal airways as a cause of snoring. Allergies should be diagnosed and treated by a doctor.
Can I keep using a nasal spray?
Decongestant sprays are not recommended for long-term use without advice; ask a pharmacist or doctor.
