Do Scented Nasal Strips Actually Work?

By Massner Team October 01, 2026 · 12 min read

Scented nasal strips promise two things at once: a clearer nose and a calmer night. Mint for that cool, open feeling, lavender or chamomile for winding down, rose or peach because a pleasant smell at bedtime is nicer than no smell at all.

The honest answer is that these are two different jobs, done by two different parts of the strip, with two very different levels of evidence behind them. The spring band does the physical work. The scent is a comfort, a sensation and a bedtime cue, and the research on each scent ranges from a few decent trials to nothing at all.

Here is what each part is doing, what the studies on each scent actually found, and how to choose.

What the Band Does and What the Scent Does

A nasal strip works mechanically. The spring band tries to straighten after you press it on, and in doing so it lifts the sides of the nose outward and widens the narrowest part of the nasal passage. We explained that mechanism, and the kinds of snoring it can and cannot help, in do nasal strips help with snoring.

The important point for this article is that the scent does not change how the band works. A mint strip and an unscented strip lift the nostrils by exactly the same mechanism. Any extra effect from the scent has to come from somewhere else: how the nose feels, how relaxed you are, and what the smell comes to mean to you at bedtime.

So the useful question is not whether scented strips work. It is whether the scent adds anything on top of the band, and for whom.

Menthol: A Real Effect, Mostly on Sensation

Menthol has the clearest research on what it does to the nose, and that research is surprisingly specific.

A double blind randomised trial in the Journal of Pharmacy and Pharmacology studied 62 people with nasal congestion from a naturally caught common cold. One group sucked a lozenge containing 11 mg of menthol and the other a sweet placebo lozenge. The researchers measured two things: the actual resistance to airflow through the nose, using a technique called rhinomanometry, and how open each person felt their nose was, using a rating scale.

The results split cleanly in two. Measured nasal resistance rose in both groups over the two hour experiment, with no difference between menthol and placebo at any point. But the menthol group reported a marked improvement in the sensation of airflow within 10 minutes of dosing, while the placebo group reported no change. The authors concluded that menthol had no effect on measured resistance but produced a subjective sensation of nasal decongestion.

In plain terms: menthol makes a blocked nose feel clearer without making it measurably clearer.

That is not a reason to dismiss it. How open your nose feels affects how comfortable you are lying in the dark trying to fall asleep, and a cool, fresh sensation can make congestion feel less oppressive. It simply means the opening itself is still the band's job. If your nose is properly blocked, a menthol strip will feel nicer than an unscented one, but it will not clear the swelling. That needs a different approach, which we compare in nasal strips vs decongestant spray.

One caveat on the evidence: that trial used a lozenge, not a strip. The menthol reached the nose a different way, so it shows what menthol does to the sensation of airflow rather than testing a menthol strip directly.

Lavender: The Most Studied Sleep Scent

Lavender is the most familiar sleep scent, and two studies are worth knowing in detail because they measured different things.

The sleep laboratory study. Researchers at Wesleyan University brought 31 healthy young sleepers, 16 men and 15 women aged 18 to 30, into a sleep laboratory for three nights: one to get used to the lab, one with lavender and one with plain distilled water as a control. The scent was released for the first 2 minutes of every 10 minute interval between 23:10 and 23:40, so it was present around bedtime rather than all night. Sleep was recorded with full polysomnography.

Lavender increased the percentage of deep, slow wave sleep in both men and women, and everyone reported feeling more vigorous the next morning. Some other effects differed by sex: in women, lavender increased light sleep and reduced dream (REM) sleep, while men showed the opposite pattern.

That is a genuine finding, but it is one small study of healthy young adults in a laboratory, with the oil diffused into the room before sleep. It did not test a strip, and it did not test people who snore.

The patch study. A randomised controlled trial at the University of Minnesota is closer to how a scented strip is used. It enrolled 79 college students who reported sleep problems. For five nights, everyone practised good sleep habits and wore an inhalation patch on the chest at night. One group's patches held 55 microlitres of lavender essential oil; the other group's were blank.

The lavender group reported better sleep quality after the five nights and still at a two week follow up, along with feeling more refreshed on waking. But the blank patch group improved too, just to a lesser degree, and sleep quantity, measured with a wrist tracker and a sleep diary, did not differ between the groups.

Read together, the two studies suggest lavender can nudge how well people feel they sleep, and possibly the depth of sleep, but the effects are modest and partly tangled up with the simple act of building a better bedtime routine.

Chamomile and Rose: Promising but Thin

Both have trial evidence for their scent specifically, though each body of evidence has clear gaps.

Chamomile. Chamomile has been studied in other forms, including massage with chamomile oil. When researchers in Chennai, India, ran a randomised trial of chamomile oil inhalation, they noted that, to their knowledge, no previous randomised trial had looked at inhaling it for insomnia. Their study took 80 adults aged 18 to 35 with insomnia. Forty inhaled chamomile oil for 10 minutes before bed every day for 15 days; the other 40 kept to their normal routine.

The chamomile group showed significantly greater improvements in sleep quality and insomnia severity scores than the control group, and nobody reported side effects. The authors themselves pointed out the main weakness: the control group had no scent at all, so the trial cannot separate chamomile from the effect of a 10 minute relaxing ritual. They called for a repeat with an active control.

Rose. Rose has more pooled evidence than chamomile. A 2025 systematic review and meta-analysis in Frontiers in Public Health combined 28 randomised controlled trials of Rosa damascena aromatherapy. Rose scent was associated with lower anxiety and stress scores and improved sleep quality, but had little effect on low mood or pulse rate. Even so, the authors called for larger randomised trials, and the review looked at rose aromatherapy in general rather than rose scent on a nasal strip.

Neither result is strong enough to promise a better night. Both are reasonable grounds for thinking that if you like the smell, it may help you relax.

Peach: No Evidence Either Way

We could not find any published trials looking at peach scent and sleep. That is not evidence that it does nothing; it means nobody appears to have tested it.

Peach is best thought of as a preference scent. If you find it pleasant and it makes the strip more appealing to put on every night, that is a perfectly good reason to choose it. Consistency matters more than which scent you pick, because a strip only works on the nights you wear it.

The same logic applies to every scent on this list. The band does the same job underneath, so the right choice is the one you will actually use.

Why Scent Works Best as a Bedtime Cue

There is a pattern running through the lavender and chamomile studies. In both, the scent was paired with a routine: sleep hygiene in one, a nightly 10 minute ritual in the other. And in both, the comparison group that followed the routine without the active scent also improved.

That points to a practical way of thinking about scented strips. Putting one on can become a signal that the day is over. The same smell, at the same point in the evening, after the same few steps, gives your brain a consistent cue that it is time to wind down. The research cannot tell us how much of the benefit is the plant and how much is the habit, and for you as a sleeper it may not matter.

To make the most of that, build the strip into a short, repeatable routine rather than slapping it on at the last moment:

Dim the lights and put screens away for the last half hour.
Wash and dry your nose so the strip sticks properly.
Apply the strip as one of the last things you do before lying down.
Keep the order the same every night, so the routine itself becomes familiar.

Choosing Between the Scents

Because the evidence is limited and the band works the same way in every version, the choice comes down to what you want from the scent.

Pick mint if your nose feels blocked. Menthol is the one scent with good evidence for changing how clear your nose feels. A mint strip suits people who like that fresh, cool sensation at bedtime, particularly when they have a cold.

Pick lavender, chamomile or rose if you want help winding down. These have some evidence for relaxation and perceived sleep quality, with lavender and rose the best studied. A chamomile strip is a gentler, less medicinal smell than mint if menthol feels too sharp.

Pick peach for pure preference. There is no research either way, so choose it if you like it.

Pick unscented if smells bother you. Some people find any fragrance distracting at night, some partners dislike it, and some skin is more sensitive to added ingredients. An unscented strip such as the large sleeping strip gives you the same lift without the extra.

Whichever scent you choose, fit matters more than smell. A strip that does not suit the width of your nose will not lift as well, and no scent will make up for that.

When a Scented Strip Is Not the Answer

A scent cannot change where your snoring comes from. If the noise starts in the throat or the tongue, the strip helps only with the nasal part of the picture, and the scent does not change that.

Stop using a scented strip if your skin becomes red, itchy or sore where it sits, and switch to an unscented one. If the problem continues with unscented strips, give your skin a rest and speak to a pharmacist.

And do not let a pleasant bedtime ritual mask a more serious problem. Loud snoring with pauses in breathing, gasping or choking at night, or heavy daytime sleepiness despite a full night in bed are reasons to see a GP rather than to try another scent.

Frequently Asked Questions (FAQs)

Do scented nasal strips work better than unscented ones?

They open the nose by the same mechanism, because the spring band works the same way. The scent adds a sensation or a calming smell on top. Menthol makes a nose feel clearer, and lavender, chamomile and rose have some evidence for relaxation, but none of these makes the band lift any harder. Choose the one you will wear every night.

Does menthol actually unblock your nose?

Not in measurable terms. In a randomised trial of 62 people with colds, an 11 mg menthol lozenge did not change measured nasal resistance compared with placebo, but it produced a marked improvement in how clear people felt their nose was within 10 minutes. It changes the sensation of airflow rather than the airway itself.

Can lavender really help you sleep?

Possibly, a little. In a sleep laboratory study of 31 young adults, lavender diffused at bedtime increased the share of deep sleep. In a trial of 79 students, a lavender patch plus good sleep habits improved reported sleep quality more than a blank patch plus the same habits, though both groups improved and total sleep time did not differ.

Is there any evidence for rose or peach scents?

For rose, yes, though it is limited. A 2025 meta-analysis of 28 trials found rose aromatherapy was associated with lower anxiety and better sleep quality, and the authors still called for larger trials. For peach, we could not find any published sleep research, so it is best chosen simply because you like it.

Can I use a mint strip when I have a cold?

Yes. A mint strip is a sensible choice with a cold, because the band lifts the nostrils and the menthol makes the nose feel clearer. It will not reduce the swelling inside the nose, so if you are badly blocked you may also want to ask a pharmacist about saline or a short course of decongestant.

What should I do if a scented strip irritates my skin?

Take it off gently with warm water, give the skin a night or two to settle, and switch to an unscented strip. Added fragrance is one more ingredient sitting on the skin all night, so removing it is a simple first step. If irritation continues even with unscented strips, stop using them and speak to a pharmacist.
