A nasal strip is a simple thing — an adhesive band across the bridge of the nose. But for people who wake up with a dry mouth, snore, or struggle with congestion at night, they’re one of the more reliably effective tools available. Here’s how they work.
What nasal strips do
Nasal strips are adhesive bands worn across the bridge of the nose during sleep. They work mechanically — the band is slightly rigid, and when applied to the nose it gently pulls the sides of the nasal passages outward, widening the airway.
That’s it. No drugs. No adjustment period. No side effects beyond the occasional adhesive residue. You put it on, it opens your nose, you breathe through it more easily.
The mechanism behind the improvement
The nose is the body’s preferred airway. It filters, humidifies, and warms incoming air in ways the mouth cannot. Nasal breathing also produces nitric oxide, a molecule that dilates blood vessels, improves oxygen uptake, and has been linked to lower blood pressure and better cardiovascular function during sleep.
When the nasal passage is congested or structurally narrow, airflow resistance increases. The body compensates by switching to mouth breathing — which bypasses those benefits, dries out the throat, and significantly increases the likelihood of snoring.
Nasal strips reduce that resistance without medication. They’re particularly effective for people whose congestion is situational (allergies, minor inflammation, the effects of cold air) rather than the result of a structural issue like a severely deviated septum.
What does the research actually show?
Reasonably well-evidenced for a product in this category.
A study published in the American Journal of Rhinology found that external nasal dilators significantly reduced nasal airway resistance in participants compared to placebo strips. A separate trial in athletes found improved airflow and reduced mouth breathing during sleep when nasal strips were worn.
On snoring specifically: multiple small studies have found reductions in snoring frequency and intensity with nasal strips, particularly in people whose snoring originates from nasal congestion rather than throat anatomy. They are not a treatment for obstructive sleep apnoea — that’s an important distinction — but for simple snoring with a nasal component, they’re one of the more evidence-backed interventions available without a prescription.

Who they work best for
Nasal strips are worth trying if you:
- Snore and suspect a blocked nose is part of the cause
- Wake up with a dry mouth (a sign of mouth breathing)
- Have allergies, hayfever, or frequent mild congestion
- Find breathing through your nose difficult in cold weather
- Are a runner or athlete interested in optimising sleep recovery
They are less likely to help if snoring is caused by throat anatomy, excess weight, or sleep apnoea — all of which have different mechanisms and require different interventions.
Using nasal strips alongside mouth tape
A growing number of sleep-focused people use nasal strips and mouth tape in combination. The logic is straightforward: mouth tape encourages nasal breathing by keeping the mouth closed, but if the nasal passage is congested, that combination becomes uncomfortable. Nasal strips remove that bottleneck, making the mouth tape more effective and the overall sleep quality better.
It sounds like an unusual bedtime routine. It works.
What to look for in a nasal strip
A few things worth checking:
- Adhesive quality — it needs to hold through a night of movement and sleep sweat without slipping. Cheap strips frequently fail here.
- Flexibility of the band — too rigid and it’s uncomfortable; too flexible and it doesn’t open the airway meaningfully.
- Skin sensitivity — if you have reactive skin, look for strips with gentler adhesive formulations.
The DreamFlow nasal strips from SleepyDeepy are drug-free, available in black or pink, and designed to hold securely through the night without irritating the skin. At £9.99 for 20 strips, they’re also one of the more accessible options in the category.
The bottom line
Nasal strips are not a cure for complex sleep disorders. But for the large proportion of people who breathe through their mouth at night, wake up congested, or snore with a nasal component, they address the actual mechanism — not just the symptom.
That makes them worth far more than their reputation as a novelty item. Try them for a week. The evidence, and most people who use them, suggests you’ll notice the difference fairly quickly.
