Do Nasal Strips Work for Snoring? An Honest Answer

Short answer

Nasal strips do something real, but narrower than the packaging suggests. They measurably widen the nasal valve and lower nasal airway resistance, which is why some people whose noses block or collapse at night snore less and wake with a less dry mouth. They are not a treatment for obstructive sleep apnoea, and on that point the evidence is not ambiguous: pooled trials find no meaningful change in the apnoea-hypopnoea index, and strips are now used deliberately as the placebo arm in trials testing CPAP. If you snore heavily, gasp or choke in your sleep, or wake unrefreshed after a full night, the honest next step is assessment, not a strip.

We sell nasal strips. That is disclosed further down, and it is why this page is careful rather than enthusiastic.

Read this before the evidence

There is a specific reader this page worries about: tired every morning, told they snore, hoping a cheap adhesive strip fixes it. That combination is the classic presentation of undiagnosed obstructive sleep apnoea, and a strip will not touch it.

The signs that mean assessment rather than a purchase, which are also the ones NHS guidance on snoring flags:

Loud, habitual snoring, especially if broken by silences
Anyone having seen you stop breathing, gasp or choke in your sleep
Waking unrefreshed month after month regardless of hours in bed
Falling asleep unintentionally during the day, and above all at the wheel
Morning headaches, or a persistently dry mouth and sore throat

None of those is a diagnosis, and plenty of people snore without having apnoea. But that cluster is a pattern clinicians recognise, it is confirmed with a sleep study rather than a symptom checklist, and it is treatable. Sleep apnoea and morning tiredness sets out what assessment involves. Buying a strip and feeling slightly better for a fortnight is a way of losing a year. The same holds if your nights are broken by waking repeatedly to pass urine or restless legs.

What a nasal strip physically does

An external nasal dilator is adhesive tape with one or two springy plastic bands laminated inside it. Stuck across the bridge of the nose, the bands try to return to flat and pull the soft outer walls of the nostrils outwards. That is the entire mechanism. No drug, no electronics, nothing reaching past the front of your nose.

It acts on the nasal valve, the narrowest section of the nasal airway. A review by Dinardi and colleagues in the International Journal of General Medicine puts the nasal valve at roughly 50 to 60 per cent of total resistance to airflow through the nose, which is why a small change there is not trivial. That review reports studies in which strips increased cross-sectional area at the valve and cut nasal resistance by up to around 27 per cent.

So the front-end claim holds up. Strips open the nose. The question is what that buys once you are asleep.

Snoring: genuinely mixed, and the mixing is instructive

Snoring is soft tissue vibrating in the throat, palate and tongue base, not in the nose. A blocked nose contributes only indirectly, by pushing you into mouth breathing and raising the negative pressure that pulls the airway shut behind it. That predicts what the evidence shows: benefit concentrated in people whose problem starts at the nose, very little anywhere else.

The frequently cited positive study is Ulfberg and Fenton in Rhinology in 1997. Thirty-five habitual snorers wore strips for fourteen nights while their bed partners rated the snoring, and roughly half improved, along with mouth dryness and sleepiness scores. A real result, and also open-label, uncontrolled and entirely subjective, with the authors themselves calling for polysomnography. Schenkel, Ciesla and Shanga ran a better-controlled test in Allergy, Asthma and Clinical Immunology in 2018, randomising 59 people with chronic nocturnal nasal congestion against a placebo strip: sleep satisfaction and morning symptoms improved, the congestion questionnaire did not.

The systematic reviews are cooler. Camacho and colleagues, in Pulmonary Medicine in 2016, pooled fourteen studies and found no significant change in snoring index in patients with OSA. A meta-analysis by Alnabulsi in Cureus in January 2026 pooled 17 studies and 496 participants and found no significant difference in snoring index, apnoea index, hypopnoea index or oxygen saturation, concluding that nasal dilators cannot be recommended as monotherapy for sleep-disordered breathing, though they may help as an adjunct where symptoms are mild or the nose is congested.

Those findings are not contradictory. They describe a device that works on one bottleneck and does nothing about any other.

Sleep apnoea: the evidence is clear, and it is negative

In the Camacho review, across 147 patients the apnoea-hypopnoea index shifted from a mean of 28.7 to 27.4 events per hour, reported as non-significant. That is noise, not a treatment effect. The 2026 Cureus meta-analysis found the same nothing across a larger pool.

The most telling finding is not a null result at all. Yagihara, Lorenzi-Filho and Santos-Silva published a crossover trial in the Journal of Clinical Sleep Medicine in 2017 in which 26 patients with severe OSA used a nasal dilator strip and CPAP in random order. The strip had no significant effect on any polysomnographic parameter, yet produced statistically significant improvements in Epworth sleepiness scores and depression scores. The paper's title says the quiet part out loud: the nasal dilator strip is an effective placebo intervention for severe obstructive sleep apnoea. Researchers use it precisely because patients believe in it while their breathing stays exactly as bad as it was.

That should reframe what "it helped me" means in a product review. Feeling better on a strip is a reproducible effect in people whose apnoea is untreated and unchanged. If you have apnoea, that feeling is the hazard, not the benefit.

Who nasal strips genuinely suit

The group is narrow. Your nose blocks or collapses at night and the rest of your sleep is fine: rhinitis, allergy, seasonal congestion, pregnancy rhinitis, a nose that pinches shut when you breathe in hard. You mouth-breathe overnight because the nose is blocked, and wake dry. Or you are a mild, nose-led snorer whose partner finds it a nuisance rather than a nightly emergency, in which case sleep divorce and separate beds covers the other options.

If that is you, a strip is a low-stakes test. Give it a fortnight and take an outside opinion on whether the snoring changed, because your own impression is the one measure the placebo literature shows is unreliable.

What nasal strips cannot do

Treat obstructive sleep apnoea, at any severity. Using one instead of getting assessed is the main way this product does harm.
Reach the collapse behind the palate or at the tongue base, where most obstructive snoring and nearly all apnoea originates.
Fix a deviated septum, nasal polyps or enlarged turbinates. Those are structural, and an ENT conversation.
Overcome what worsens snoring regardless of your nose: back-sleeping, weight gain, smoking, sedating medication and alcohol in the evening, which relaxes the upper airway and fragments the second half of the night.
Improve athletic performance. The Dinardi review is blunt that numerous studies found no benefit there.
Stay on reliably. Sweat, facial oils, moisturiser, beards and side-sleeping all defeat the adhesive, and some skin reacts to it.
Help tiredness with another cause. If mornings are the real problem, working through the causes of waking up tired beats a shopping cart.

A strip is also not the strongest mechanical option, as the comparison with internal nasal dilators below sets out.

What this category should cost

A nasal strip is adhesive plus a sliver of springy plastic. Cheap to make, produced by many factories, sold in supermarkets and pharmacies in most countries, proprietary in no respect. Some brands in the sleep space nonetheless price strips as though there were a research programme behind them. We will not quote a competitor's figure, because prices move and a number we cannot verify today is worth nothing to you, but the check is easy: work out the cost per strip and compare it with a supermarket own-brand. Any premium is being charged for the box.

Where our own strips fit

EIVOI sells a 30-pack of drug-free nasal strips. They are ours, so treat this paragraph accordingly. Single-use, hypoallergenic adhesive, applied across the bridge of the nose, doing the one thing described at the top of this page: holding the nasal valve open. No medication, and no claim to treat anything.

Worth trying if you fit the narrow group above. Not worth buying if you snore heavily, if anyone has seen you stop breathing at night, if you wake unrefreshed after adequate sleep, or if the blockage is structural. In those cases the useful purchase is a GP appointment, and we would rather say so than take the order.

Common questions

Do nasal strips work for snoring?

Sometimes, and mainly for one type of snorer. Nasal strips widen the nasal valve and lower nasal airway resistance, so people whose snoring is driven by a blocked or collapsing nose can see a genuine reduction. Pooled analyses, including a 2016 review in Pulmonary Medicine and a 2026 meta-analysis in Cureus, find no significant effect on snoring index across mixed populations. If your obstruction sits behind the palate or at the tongue base, which is the common pattern, a strip cannot reach it.

Can nasal strips treat sleep apnoea?

No. Across pooled trials there is no meaningful change in the apnoea-hypopnoea index; one review found a shift from 28.7 to 27.4 events per hour, which was not statistically significant. A 2017 trial in the Journal of Clinical Sleep Medicine used a nasal strip as the placebo arm against CPAP in severe apnoea, and it improved how patients felt without changing a single sleep-study measure. Suspected sleep apnoea needs a sleep study and proper treatment, not a strip.

Are nasal strips or internal nasal dilators better?

On objective airflow, internal dilators generally win. A 2016 systematic review in JAMA Facial Plastic Surgery comparing over-the-counter mechanical dilators found internal nose cones produced greater improvement in peak nasal inspiratory flow than external strips. The trade-off is tolerance: many people dislike anything inserted into the nostril overnight, and comfort decides whether a device gets used at all. Both act only on the nasal valve, so neither addresses obstruction further back in the throat.

Why do nasal strips seem to work when studies say they do not?

Because feeling better and breathing better are different measurements. In the 2017 Journal of Clinical Sleep Medicine crossover trial, patients with severe apnoea using a nasal strip reported significantly less daytime sleepiness and improved mood while their polysomnography was unchanged. There is also a real mechanical effect at the front of the nose that is easy to notice while awake. Both are genuine experiences, and neither tells you whether your airway is behaving overnight.

Should I use nasal strips during pregnancy or with a cold?

Pregnancy rhinitis and short-term congestion are close to the situation strips were designed for: a blocked nose, a mechanism involving no medication, and a problem that resolves. Many people find them helpful, and being drug-free matters when medicated options are restricted. Skin can be more reactive in pregnancy, so watch for irritation. Anything beyond ordinary congestion, particularly new heavy snoring in pregnancy, is worth raising at a routine appointment rather than self-managing.
