It’s 3 a.m. One nostril is completely blocked. You roll over, and a few minutes later the other one blocks instead. You’re not imagining it: when you lie on your side, the soft tissue in the lower half of your nose swells.
If you’re wondering how to sleep with a stuffy nose, that one fact is the best place to start. 😤
Most tips online mix two kinds of fixes. Some really open your nose, while others only make it feel open. Then there’s the common decongestant pill the FDA says doesn’t work at all. Let’s sort them out, then put the good ones in order for tonight.
I didn’t test these myself. Instead, I read the studies behind them, including a 2022 review of 9 studies on how lying down changes your nose, plus FDA and CDC guidance and the makers’ details. So you get what the research shows, not a sales pitch.
The short answer
Raise your head and shoulders, and lie with the blocked side up. A decongestant spray opens the nose, but use it for 3 days at most. Rinse only with sterile, distilled or boiled water. Menthol and hot drinks just make it feel clearer. Blocked most nights while healthy? Read our Airflow Clip nasal dilator review.

Why is a stuffy nose worse at night?
Because you lie down. A 2022 review pooled 9 studies with 291 people and found that lying down raises the resistance in your nose and cuts the airflow. The effect was bigger in people who snore or have sleep apnea.
An inflamed nose makes it worse. Back in 1984, two nose researchers noted that lying down makes swollen nasal lining swell even more. A cold, hay fever or a sinus infection already has that lining puffed up, and gravity adds to it.
Then there’s the side switch. In a 2024 study of 60 adults, lying on one side made the turbinate (the soft ridge inside your nose that warms the air) swell on the lower side. Sitting up gave the best measured airflow, both in people with allergies and in healthy people.
9 studies
291 people in all: lying down raised nose resistance and lowered airflow
Dry, heated winter air can make it feel worse too, which is why our humidifier guide aims for 40% to 50% humidity in the bedroom. So the first fixes are about how you lie. Good news: they cost nothing.
The best position to sleep with a stuffy nose
Think “higher, and blocked side up”. Since upright is where your nose works best, get your head and shoulders above your chest, not just your head bent forward on a pile of pillows.
- Raise your upper body Add a pillow under your shoulders as well as your head, or use a wedge. Our wedge pillow guide explains the slope and why people slide down it.
- Lie on your side, blocked side up If the left nostril is the blocked one, lie on your right side. The lower side swells, so let the blocked side be on top.
- Switch when it switches If the lower nostril blocks after a while, roll over. It’s not your cold getting worse; it’s the side you’re lying on.
Back sleeping with your head raised is fine for your nose, but if you snore, your back is the worst position for that. Our sleep position guide covers why. So, position helps. But what about everything in the medicine cabinet? 🧴
What really opens your nose, and what only feels like it
Here’s the part most guides skip. Researchers can measure the air moving through your nose with a machine, and they can ask you how clear it feels. Some popular remedies change the feeling and not the airflow.
| Remedy | Opens the nose? | What the research found |
|---|---|---|
| Raising your upper body | ✅ Yes | Lying flat raised nose resistance in 9 studies |
| Blocked side up | ✅ Yes | The lower side’s turbinate swells (60 people) |
| Decongestant spray (oxymetazoline) | ✅ Yes | The label says 3 days at most |
| Saline rinse | ➖ Washes out mucus | Safe only with sterile, distilled or boiled water |
| Nasal strips | ➖ Mixed | No better than fake strips for sleep in 2 trials (270 people) |
| Menthol lozenge | ❌ Feels open | Airflow unchanged, but people felt clearer (62 people) |
| Hot drink or chicken soup | ❌ Feels open | Airflow unchanged; mucus moved faster for about half an hour |
| Phenylephrine pill | ❌ No | FDA, 2024: not effective as a decongestant |
Menthol, hot drinks and soup: they feel better
In a 1990 trial, 62 people with colds took a menthol lozenge or a plain candy. A machine found no change in their nasal airflow, yet the menthol group felt their nose was clearer within 10 minutes. So the menthol changed the feeling, not the air. Sneaky, right? 🧊
A hot drink works the same way. In 30 people with a cold or flu, a hot fruit drink didn’t change the measured airflow, but it eased the feeling of a blocked nose, plus the runny nose, cough, sneezing, sore throat, chills and tiredness.
And grandma’s chicken soup? In a 1978 study of 15 healthy people, sipping hot water or hot chicken soup sped up the mucus in the nose for about half an hour, with soup a little ahead. Cold water slowed it down. Airflow didn’t change with any of them.
Does “only feels better” mean useless? Not at 2 a.m. Feeling able to breathe can be what lets you fall asleep. Just don’t expect them to do the job of the fixes above.
The decongestant pill that doesn’t work
Many “sinus” and “cold and congestion” tablets contain phenylephrine. On 7 November 2024 the FDA proposed removing oral phenylephrine as a decongestant because it is not effective. It was about effectiveness, not safety.
On 28 October 2026 the FDA’s order page still lists it as only a proposal, so the pills are still on the shelf. Check the Drug Facts label, and ask the pharmacist for a different option. The FDA’s finding doesn’t cover phenylephrine nasal spray.
Decongestant sprays: the 3-day rule
Oxymetazoline sprays shrink the swollen lining, so they really open the nose. But the labels say don’t use them for more than 3 days, because frequent or longer use can make the stuffiness come back worse. Ask a doctor first if you have heart disease, high blood pressure, thyroid disease, diabetes or an enlarged prostate. Our nasal spray guide compares the saline, steroid and decongestant types.
Saline rinses: only with safe water
A neti pot or squeeze bottle washes mucus out. The FDA says to use distilled or sterile water, or tap water boiled for 3 to 5 minutes and cooled to lukewarm. Tap water straight from the tap isn’t safe, because organisms in it can survive in the nose and cause serious infections. Wash and dry the device after each use.
Nasal strips and dilators: honest expectations
Two trials paid for by the maker of Breathe Right gave 270 people with night-time congestion either real strips or fake ones for 14 nights. Both groups slept better, and the real strips did no better than the fakes. A smaller trial of 59 people did find some benefit.
A strip widens the front of the nose, not the swollen lining further in, so for a cold it’s a “might help” at best. In our nasal dilator review, a strip is fine for the odd night with a cold.
Your plan for tonight
Put it together and the evening looks like this. Skip any step that doesn’t fit you, and check medicine labels before you take anything.
- Evening Have warm drinks and soup. They won’t open your nose, but they ease the cold symptoms and the stuffy feeling.
- An hour before bed Take a hot shower. If you rinse, use sterile, distilled or boiled-and-cooled water. Read the label before any spray or pill, and skip phenylephrine tablets.
- Getting into bed Prop your shoulders and head up, set the humidifier for 40% to 50%, and keep tissues and water within reach.
- Lights out Lie on your side with the blocked nostril on top. A menthol rub or lozenge is fine if the cool feeling helps you settle.
- At 3 a.m. Blocked again? Roll over so the blocked side is up, or sit up for a few minutes. Sitting upright is where your nose breathes best.
Can a stuffy nose make you snore?
Yes, and it’s often why someone who never snores starts during a cold. With your nose blocked, you breathe through your mouth, and the soft palate at the back of the throat flutters in the airflow.
The link shows up in big numbers too. In the Wisconsin Sleep Cohort, 4,927 adults answered questions about their nose and sleep. People with nose symptoms on 5 or more nights a month were significantly more likely to be habitual snorers, to feel very sleepy in the day, and to wake up unrefreshed.
Cold snoring usually goes when the cold does. Until then, the partner can borrow a few tricks from our guide on sleeping next to someone who snores, or pick a pair from our earplugs guide. If the snoring started suddenly and stayed after you got better, our sudden snoring guide lists the usual triggers.
Blocked every night, even when you’re not sick?
A cold lasts days. A nose that blocks up most nights for weeks is a different story, and the fixes are different too. Remember the Wisconsin numbers: nose symptoms on 5 or more nights a month went with more snoring, more daytime sleepiness and more mornings waking up unrefreshed. So it’s worth finding the cause. Here are the usual suspects:
- Allergies Bedroom triggers like dust mites and pets can keep the lining swollen. An allergist can test you, and steroid sprays are covered in our nasal spray guide.
- Too much decongestant spray Used past the label’s 3 days, the spray itself can keep the stuffiness coming back.
- Nostrils that close as you breathe in The soft sides of the nose get sucked in. A nasal dilator helps most here.
- A bent septum or nasal polyps An ear, nose and throat (ENT) doctor can see these and tell you what will help.
The 10-second nostril check, and the Airflow Clip
When you’re well, close one nostril with a finger, keep your mouth shut and breathe in through the other. Then swap sides. If the open nostril closes up or feels tight as you breathe in, the soft side of your nose is collapsing. That’s when a nasal dilator can make the most difference.
The Airflow Clip is a reusable dilator that sits just inside the nostrils, with no glue. A trial pack with small, medium and large sizes was $17.99 on 28 October 2026, and one clip lasts up to 90 days. The maker calls it “FDA-registered”, which is a company listing, not an FDA clearance.
👍 A good fit if
- Your nostril closes up when you breathe in
- Your nose blocks up most nights, or you wake with a dry mouth
- Strips helped, but the glue bothers your skin
👎 Look elsewhere if
- You only get blocked with a cold
- You have a badly bent septum or polyps (see an ENT doctor)
- You may have sleep apnea: a dilator doesn’t treat it
Not sure your nose is the reason you snore? The free 1-minute snore quiz checks your nose, tongue and sleeping position at once.
When to see a doctor
- Severe symptoms, like a bad headache or pain in your face
- Symptoms that get worse after they’d started to improve
- Symptoms lasting more than 10 days without getting better, or a fever for more than 3 to 4 days
- Several sinus infections in the past year
- Gasping, choking or stopping breathing in your sleep, or strong daytime sleepiness: get checked for sleep apnea
The first four signs come from the CDC’s sinus infection page.
Babies are different: never prop a baby up on pillows or tilt the crib. The American Academy of Pediatrics says that can bend a baby’s airway. Babies sleep flat on their back; use plain saline drops and suction, and ask your pediatrician.
FAQ
Which side should I sleep on with a blocked nose?
Sleep on the side opposite the blocked nostril, so the blocked side is on top. When you lie on your side, the lower side of the nose swells, so the side that is up breathes more easily.
Does Vicks or menthol actually unblock your nose?
Menthol makes your nose feel clearer rather than opening it: in a trial of 62 people with colds, a menthol lozenge didn’t change the measured airflow. Rubs weren’t part of that trial, and the cool feeling can still help you relax and fall asleep.
Can I use a decongestant nasal spray every night?
No. Oxymetazoline labels say not to use them for more than 3 days, because longer use can make the congestion come back or get worse.
Why does my nose get blocked only at night?
Lying down raises the resistance in your nose, and an inflamed lining swells more when you’re flat. Bedroom allergens and dry heated air can add to it.
How do I help my baby sleep with a stuffy nose?
Keep your baby flat on their back, use plain saline drops and gentle suction, and run a cool-mist humidifier. Never prop a baby up or tilt the crib, and ask your pediatrician about anything else.
My verdict
For a cold, the free fixes come first: head and shoulders up, blocked side up, and roll over when it switches. A decongestant spray is the strongest short-term help, for 3 days at most, and a saline rinse needs safe water. Enjoy the tea and menthol for how they feel, and skip the phenylephrine pills.
If your nose is blocked most nights even when you’re healthy, do the nostril check. The Airflow Clip is the dilator I’d look at first.
