Do Nasal Strips Work for Snoring? An Honest Look

Nasal strips are probably the first thing most snorers try: cheap, drug-free, available in every supermarket, and endorsed by athletes. So, do they work?

Here’s the honest answer up front. Nasal strips and internal nasal dilators do not meaningfully treat sleep apnoea — the research is clear on that — but they can produce modest, subjective improvements in snoring and sleep quality for some people, particularly those whose snoring starts in a blocked nose.^[1] They are a comfort measure, not a cure.

The more useful question is usually the one behind it: why is your nose blocked at night in the first place? Treating the underlying congestion often has better evidence than sticking a strip over it.

What nasal strips and dilators actually do

External nasal strips (the Breathe Right type) are springy adhesive bands worn across the bridge of the nose; as they try to straighten, they gently pull the nostril walls outward. Internal dilators (such as NoZovent-style devices) sit just inside the nostrils and hold them open from within. Both aim to widen the nasal valve — the narrowest part of the nasal airway — so that air flows in with less effort and less turbulence.

The logic is sound as far as it goes. The limitation is anatomical: most snoring noise is generated further back, where the soft palate and throat tissues vibrate — something a strip on your nose cannot reach. Our guide to what causes snoring explains where the sound actually comes from.

What the evidence shows Weak evidence

The key study is a 2016 meta-analysis by Camacho and colleagues, which pooled the trial evidence on external strips and internal dilators. Its conclusion: these devices do not meaningfully reduce the apnoea-hypopnoea index (AHI — the number of breathing disturbances per hour of sleep). In other words, they are not a treatment for obstructive sleep apnoea. The same review did find some subjective improvement in snoring for some users.^[1] A more recent systematic review and meta-analysis reached a similar verdict: modest, limited effects.^[2]

That pattern — little objective change, some perceived benefit — runs through the older literature too. A placebo-controlled study back in 1997 found only a small effect from nasal strips.^[3]

The most positive result comes from the group you might predict: people with blocked noses. A 2018 randomised controlled trial in people with chronic nasal congestion found that wearing a nasal strip improved subjective sleep quality.^[4] If your nose is genuinely obstructed at night, holding it open can make breathing feel easier — even if the snoring itself only improves a little.

Why your blocked nose still matters

Don’t read the above as “the nose is irrelevant”. It isn’t. In the Wisconsin cohort studied by Young and colleagues, people with chronic night-time rhinitis (an inflamed, congested nose) had twice the odds of habitual snoring (odds ratio 2.0), and those with congestion from allergy were 1.8 times more likely to have moderate-to-severe sleep-disordered breathing.^[5]

A blocked nose forces harder inspiratory effort and encourages mouth breathing, both of which set the stage for the throat vibration that produces snoring. So nasal congestion is a genuine, well-documented risk factor — the issue is that a strip only splints the nostrils; it doesn’t treat the inflammation causing the blockage.

How to tell if your nose is part of the problem

Before buying anything, it’s worth working out whether nasal obstruction is actually contributing to your snoring. Some pointers that suggest it is:

• Your snoring gets noticeably worse with colds, hay fever season, or dusty environments.
• You regularly wake with a dry mouth, suggesting you’ve been mouth breathing overnight.
• One or both nostrils feel blocked when you lie down, even if they seem fine during the day.
• A simple self-check: close one nostril with a finger and breathe in through the other, then swap. If one side collapses or feels far harder to breathe through, the nasal airway may be narrowed.

None of this replaces a proper examination — persistent one-sided blockage in particular deserves a GP visit — but it helps you predict whether a nasal-focused approach is worth trying at all. If your nose feels clear and you still rattle the windows, the source is almost certainly your palate or tongue base, and a strip won’t touch it.

The smarter play: treat the congestion itself Moderate evidence

If allergy or rhinitis is behind your night-time blockage, the better-evidenced option is to treat it. A 2024 meta-analysis found that intranasal corticosteroid sprays improve sleep disturbance in people with allergic rhinitis.^[6][7] Earlier work in the Journal of Allergy and Clinical Immunology similarly showed nasal steroids improving sleep and daytime somnolence in allergic rhinitis.^[8] There is even evidence that intranasal steroids help children with sleep-disordered breathing^[9] — though a snoring child should always be assessed properly first, as our snoring in children guide explains.

Two important notes. These are medicines: talk to a pharmacist or your GP before starting a steroid spray, especially for long-term use or for a child. And they treat allergic congestion — they are not a universal snoring remedy.

Saline rinses and sprays are also commonly suggested for clearing congested noses before bed. They’re a gentle comfort measure rather than a proven snoring treatment — we make no efficacy claims for them here.

Who might still reasonably try nasal strips?

Strips have three genuine virtues: they’re cheap, they’re about as safe as an intervention gets, and you’ll know within a few nights whether they help you. A reasonable trial makes sense if:

• Your snoring seems to start in the nose — congestion, a “blocked” feeling, or snoring that’s worse during colds and allergy season.
• Your partner reports steady snoring without pauses, gasping or choking (if those are present, see below).
• You want something drug-free while you sort out the underlying cause.

Set your expectations accordingly: the likely best case is somewhat quieter, more comfortable breathing — not silence. If strips do nothing after a week or two, the evidence says the problem probably lies further back in the airway, and options like mandibular advancement devices or positional therapy are better supported.

What nasal strips will not do

It’s worth being blunt, because packaging rarely is:

• They will not treat obstructive sleep apnoea.^[1]
• They will not fix snoring generated at the soft palate or tongue base — the most common sources.
• They will not address the weight, alcohol and lifestyle factors that drive most habitual snoring.

If you or your partner suspect sleep apnoea, a strip is not a safe substitute for assessment. Untreated OSA carries real cardiovascular risks, covered in our article on the health risks of snoring.

The bottom line

Do nasal strips work for snoring? Mostly no, a little yes. They don’t touch sleep apnoea and they won’t silence palate-based snoring, but for congested, nasal-sounding snorers they can modestly improve how sleep feels — at pocket-money cost and essentially zero risk. Just don’t stop there: identify why your nose is blocked, treat that properly, and reassess. Your nose deserves better than a plaster.
