Chin strap vs nasal strips: which helps your snoring and mouth breathing?

A chin strap and a nasal strip both aim at quieter, nose-first breathing, but they work at opposite ends of the problem. A chin strap wraps under your chin and over your head to hold your jaw closed. A nasal strip sticks across the outside of your nose and lifts the sides open so air flows in more easily. If your nose feels blocked or narrow, start with the nose, because closing your mouth won't help if air can't get through it. If your nose is clear and your jaw still drops open, a mouth-closing device becomes worth considering.

What does each one target?

Each one targets a different reason for snoring and mouth breathing. The NHS matches snoring treatments to the cause. For a mouth that falls open while you sleep, it suggests a chin strap to hold the mouth closed or a device worn in the mouth that makes you breathe through your nose. For blocked or narrow airways in the nose, it suggests nasal dilators or strips that hold the nose open, or decongestants and nasal sprays to reduce swelling inside.

The two problems often travel together. Cleveland Clinic says most people breathe through their mouth because they can't get air in through their nose, and lists nasal congestion from allergies, colds or chronic sinusitis, a deviated septum and swollen turbinates among the causes. If that's why your mouth is open, a chin strap treats the symptom and leaves the cause in place. Our guide to why your mouth falls open when you sleep goes through the other reasons.

What does the research say about chin straps?

The research on chin straps for snoring is thin and mostly unencouraging. In a 2014 study in the Journal of Clinical Sleep Medicine, 26 adults with obstructive sleep apnea wore only a chin strap for the first two hours of an overnight sleep study, then switched to CPAP. Compared with their earlier diagnostic study, the strap made no significant difference to snoring, breathing pauses or the lowest blood oxygen level. Even the 13 people with mild sleep apnea didn't improve on breathing pauses or oxygen. CPAP improved all of these. The authors concluded that a chin strap alone doesn't treat sleep apnea and doesn't improve snoring.

A 2004 study in Sleep Medicine tested chin straps where they're most often used, with CPAP. Fifteen CPAP users with mouth leak, who also complained of a dry mouth and nasal obstruction, slept one night with a strap and one without. The strap cut mouth leak from about 43% of total sleep time to 24% and reduced arousals. But the time spent snoring rose from about 7% to 24% of the night, and the authors warned that a strap may increase snoring and, in rare cases, worsen breathing problems in sleep.

A 2025 systematic review in PLOS One looked at 10 studies with 213 patients on mouth taping, mouth seals and chin straps. It called the overall evidence uncertain, rated the mouth taping studies poor quality, and found that four of them warned closing the mouth could pose a serious risk of suffocation if the nose is blocked or the person vomits. The full background is in our guide to chin straps for snoring.

What does the research say about nasal strips?

The research on nasal strips is clearest about what they do to the nose. In a 1998 study in Laryngoscope, an external nasal dilator widened the narrowest part of the nose and lowered nasal resistance in 51 people with healthy noses, 33 with congestion from swollen nasal linings and 28 with a deviated septum near the nasal valve. The effect was largest in the deviated septum group. People with swollen linings measured better but didn't feel much clearer.

For snoring, a 2000 randomized trial in the European Respiratory Journal tested a strip in 12 nonobese people with chronic rhinitis who snored but didn't have sleep apnea. Compared with a placebo strip, the real strip lowered snoring frequency from about 258 to 173 snores an hour, though it didn't change loudness or measured sleep quality.

Strips don't treat sleep apnea. A 2016 meta-analysis in Pulmonary Medicine found nasal dilators improved nasal breathing but didn't improve sleep apnea measures. Our nasal strip research roundup covers the wider set of studies.

How do a chin strap and nasal strips compare?

Here's how the two compare side by side.

Why should you clear your nose before using any mouth-closing device?

You should clear your nose first because a chin strap or mouth tape leaves your nose as your only airway. If it can't carry enough air, you either fight the device all night or end up uncomfortable and short of breath. The 2025 review's warning about suffocation risk applies to tape, seals and straps alike, and it noted that many of the studies it covered excluded anyone with nasal obstruction.

Researchers who've had good results with mouth closing tend to sort out the nose first. In a 2022 study in Healthcare of 20 mouth breathers with mild sleep apnea, people with nasal obstruction were given medication and nasal sprays to ease their symptoms and make mouth taping possible. The participants had a baseline home sleep test and a second test one week later on a night with their mouths taped, and 13 of the 20 cut their snoring by at least half on that taped night. The study was small, had no control group, and isn't evidence that tape treats sleep apnea.

A nasal strip is one simple way to give your nose more room. Our nose test helps you check whether you breathe comfortably through your nose with your mouth closed. If a narrow nose is the issue, our pick is TitanAir Nasal Strips, covered below.

Can you use a chin strap and nasal strips together?

You can use a chin strap and nasal strips together, and if you're set on a chin strap, opening the nose first is the sensible order. The strip makes nose breathing easier, and the strap keeps the jaw from dropping. No study has tested this combination, so treat it as an experiment: add one thing at a time and record your snoring for a few nights with and without each.

If a strap around your head doesn't appeal, mouth tape does a similar job by keeping the lips together, with nothing around the head. Our mouth tape vs. chin strap guide compares the two. Titan says its TitanAir Nasal Strips are designed to pair with its mouth tape. We don't recommend mouth tape for children.

Who suits which?

Nasal strips suit people whose snoring or mouth breathing seems to start in the nose. That includes people who feel stuffy at night, snore more with colds or allergies, or wake with a dry mouth. They're also low-commitment: you can try one tonight and take it off in seconds.

A chin strap suits a narrower group. It mainly makes sense for CPAP users with mouth leak, where it has some evidence, and where a sleep doctor can guide its use. For snoring on its own, the evidence so far doesn't favor it.

Many people land somewhere in between: a nose that needs a little help and a jaw that drops open. For them, a strip first and a mouth-closing option second is a reasonable plan. See mouth tape and nasal strips together for how that works in practice.

When should you see a doctor?

See a doctor if your snoring is loud and comes with other symptoms, or if you can't breathe comfortably through your nose. The NHS says to see a GP if your breathing stops and starts while you sleep, you make gasping, snorting or choking noises, or you feel sleepy during the day, since you may have sleep apnoea. It also says to see a GP if lifestyle changes aren't helping your snoring.

If you use CPAP and have mouth leak, ask your sleep team before adding a chin strap or anything else. A nose that's blocked most nights, or always on one side, deserves a check too. If you're pregnant, ask your midwife or doctor before trying new products.

Our pick (paid partner): TitanAir Nasal Strips

For the nose side of this comparison, our pick is TitanAir Nasal Strips. We don't recommend a chin strap brand, and we haven't tested or ranked nasal strips ourselves. This is our recommendation, based on how Titan describes its strips.

Titan describes them as drug-free external nasal dilators with flexible spring-loaded bands. They go just above the flare of the nostrils, on the soft part of the nose rather than the bony bridge, on clean, dry skin without moisturizer. To remove one, Titan suggests loosening it with warm water and peeling slowly from the ends inward. Titan says they're designed to pair with its mouth tape, which suits anyone who wants a nose-first plan with a mouth-closing step after.

Titan says its strips are third-party tested and certified PFAS-free, and they come with a 30-night guarantee that refunds you if your sleep isn't better after 30 nights.
