How to unblock your nose before bed

For most people, the practical routine is a saline rinse, a warm shower or humidifier, a raised pillow, and a nasal strip once you're in bed. None of these is a strong treatment on its own, but they're low risk and can be combined. Decongestant sprays are the one common option to use sparingly.

Why does a blocked nose feel worse at bedtime?

The Sleep Foundation notes that lying flat can make sinus congestion worse, perhaps because of changes in blood flow.

The research backs this up. A 2022 meta-analysis in The Laryngoscope pooled nine studies with 291 people and found that lying down increases nasal resistance and reduces nasal airflow. The effect was about twice as large in people who snore or have sleep apnea as in healthy people. So a nose that felt manageable on the sofa can feel much more blocked once your head is on the pillow.

If this happens most nights, even without a cold, it's worth working out the cause. Our guide on why your nose gets stuffy at night goes through the common ones.

What causes a blocked nose at night?

The best fix depends on the cause, and the Sleep Foundation lists the usual suspects:

• Allergies to dust mites, pet dander, mold or pollen, which inflame the lining of the nose.
• Colds and other infections, which swell the nasal tissue and increase mucus.
• Dry air, especially in winter or air-conditioned rooms, which irritates the nasal passages.
• Rebound congestion from overusing decongestant sprays.
• Acid reflux, which can cause postnasal drip and throat irritation.
• Hormonal changes, including pregnancy and menstruation, which can make blood vessels in the nose swell.

A cold that started three days ago and a nose that's blocked every night for months need different plans. If allergies are the likely cause, why allergies feel worse at night covers the bedroom side.

What helps a blocked nose at night?

Most ways to unblock your nose at night are comfort measures with modest evidence behind them. They're worth trying because they're unlikely to cause harm when done correctly.

Rinse with saline

A salt water rinse flushes mucus out of the nose. For colds, a 2015 Cochrane review concluded that saline irrigation possibly helps with symptoms, but the trials were generally too small and at high risk of bias. One larger trial in children did find less nasal discharge and less blockage in the saline group, and less use of decongestant medicine, though the reviewers said the symptom difference may be too small to matter much. The only side effect reported was minor nasal discomfort or irritation in a minority of people.

The important part is the water. The FDA says tap water isn't safe for nasal rinsing because it isn't adequately filtered or treated, and may contain organisms that can cause serious infections. Use distilled or sterile water, or tap water boiled for 3 to 5 minutes and cooled until lukewarm. Boiled water can be kept in a clean, closed container and used within 24 hours, so you can boil it earlier in the evening. How to use a saline rinse has the full method.

If you use a medicated nasal spray too, the Sleep Foundation notes that a doctor may suggest rinsing first to help the medicine work better.

Take a warm shower or run a humidifier

The Sleep Foundation suggests a warm, steamy shower before bed to thin mucus. If you'd rather not shower, you can run the shower with the bathroom door closed and breathe the steam for a few minutes. A humidifier overnight can help prevent the kind of dryness that irritates the nose. If you use one, it recommends keeping humidity at 50% at most to avoid mold. Our guide to using a humidifier for sleep covers settings and cleaning.

Try a warm compress

The Sleep Foundation also suggests soaking a clean washcloth in warm, not hot, water, wringing it out and laying it over your nose and sinuses for several minutes. It says the warmth can help loosen mucus and is especially soothing when congestion comes from a cold or sinus pressure.

Drink something warm and clear

Warm, clear fluids help too. The Sleep Foundation says clear fluids such as water, broth or tea can help thin mucus so it drains from the sinuses. In the evening, a caffeine-free tea is the better choice.

It also notes that alcohol contains histamine, and people who are sensitive to it may get a runny nose or sneezing after drinking. If your nose is often worse after a glass of wine, that may be why.

Raise your head

A wedge pillow, a thick pillow or two regular pillows can keep your head raised. The Sleep Foundation says sleeping with your head elevated could help reduce feelings of congestion.

Clear out triggers

If allergies play a part, the Sleep Foundation suggests limiting exposure to pollen, pet dander, dust, mold, smoke and scented products before bed.

Put on a nasal strip

The Sleep Foundation says nasal strips help open the nasal passages to allow more airflow. It describes two styles: ones that sit across the bridge of the nose, and larger ones that stretch across the cheeks to open up more of the nasal passages, and says either type may help people who get congested at night.

A 2016 meta-analysis found that nasal dilators improve nasal breathing. The authors note how much a small change in size matters, citing research that a 10% increase in the cross-sectional area of the nasal cavity brings about a 21% increase in airflow. Strips don't clear mucus, and the same analysis found they didn't improve sleep apnea outcomes, but they can make the air you do get through easier to pull in. More detail in how nasal strips work.

If you rinse first, let the skin on your nose dry before putting the strip on so it sticks. How to apply nasal strips covers placement.

What does a simple bedtime routine look like?

Putting it together, an evening routine for a blocked nose might run like this:

1. About an hour before bed, boil water for a rinse and let it cool, or use distilled water.
2. Take a warm shower or stand in the steam for a few minutes.
3. Rinse your nose with saline, then use any medicated spray your doctor or pharmacist has recommended.
4. Have a warm, caffeine-free drink.
5. Switch on the humidifier and set up an extra pillow or wedge.
6. Once your face is dry, put on a nasal strip and go to bed.

You don't need every step every night. On a mild night, a strip and a raised pillow may be enough.

Should you take medicine?

Whether you should take medicine for a blocked nose depends on the cause, and a pharmacist can help you choose. The Sleep Foundation gives an overview:

• Antihistamines treat allergy symptoms, including a stuffy or runny nose, but may not help with congestion from a cold. Some cause drowsiness, so those may be better taken at bedtime.
• Steroid nasal sprays reduce inflammation and mucus in the nose, and can help with congestion from allergic and non-allergic causes.
• Decongestants shrink swelling but come with more cautions, which are below.

During pregnancy, the Sleep Foundation advises saline sprays or rinses and talking to your doctor before using any decongestant or medicated nasal spray.

Should you use a decongestant spray?

Decongestant sprays containing oxymetazoline or phenylephrine come with a time limit. Cleveland Clinic says the usual limit is three days. Using them longer can worsen congestion rather than relieve it, a problem called rebound congestion or rhinitis medicamentosa. After stopping, it can take anywhere from a few days to several weeks for the nose to feel clear again.

So a decongestant spray can get you through a few rough nights of a cold. It isn't a nightly habit. If you've been using one for longer than the label says, read decongestant spray rebound and talk to a pharmacist about other options such as steroid or saline sprays.

The Sleep Foundation adds that decongestants can raise blood pressure and make it harder to sleep, and that experts don't recommend them unless other treatments haven't worked. It also quotes a sleep physician warning that frequent decongestant use may have a stimulating effect, which isn't what you want at bedtime.

What about mouth tape?

Once your nose is clear, mouth tape is a good way to keep it that way overnight. If you tend to drift into mouth breathing after a cold or a run of stuffy nights, a strip of tape keeps your lips closed so your nose does the breathing. You can pair it with a nasal strip, which opens the nose while the tape handles the mouth. Mouth tape vs. nasal strips explains how they work together.

The timing matters. Leave tape off until your nose is clear. A 2025 systematic review of mouth taping research lists asphyxiation as a potential risk when the nose is obstructed. Before going back to it, take our two-minute nose test. Mouth tape with a cold covers when to stop and restart.

When should you see a doctor?

The Sleep Foundation advises seeing a healthcare provider if congestion lasts more than three weeks, or comes with a fever, throat pain, a persistent cough, facial swelling or blurry vision. It also suggests noting whether your nose is worse after nights when you've been around a likely trigger, such as pollen or a pet, since a doctor may want to test you for allergies.

Also see a doctor if your nose is blocked on the same side most nights, or if you snore loudly, gasp or stop breathing in your sleep.
