Nasal Dilator Strips
Specifically for Sleep Apnea
0 up • 0 down
Why it works for Sleep Apnea:
Nasal dilator strips (external adhesive strips such as Breathe Right) can reduce nasal airway resistance and may help snoring or sleep quality for people whose sleep problems are driven primarily by nasal obstruction. However, they do not reliably treat obstructive sleep apnea (OSA) — for moderate-to-severe OSA CPAP (positive airway pressure) remains the guideline-recommended first-line therapy. Europe PMC
How they work: external nasal strips contain flexible “spring” bands that mechanically pull the nasal sidewalls outward, increasing the cross-sectional area of the internal nasal valve and lowering nasal airway resistance. That mechanical widening improves airflow through the nose, which can reduce nasal-congestion driven snoring and subjective nasal obstruction. breatheright.co.uk
When that helps sleep: if your snoring or disturbed sleep is caused mainly by nasal obstruction (e.g., congestion from cold/allergy, a narrow internal nasal valve, or a deviated septum that causes nasal airflow limitation), strips often improve breathing and subjective sleep quality. But if the collapse of the upper airway is at the level of the soft palate/tongue (typical in OSA), external strips usually do not fix the root cause. Systematic reviews and randomized studies show subjective improvements for many users but mixed or minimal objective effects on apnea indices (AHI). JCSM
How to use for Sleep Apnea:
Manufacturer instructions vary slightly by brand, but standard, evidence-based steps:
- Clean & dry: wash and thoroughly dry the bridge and sides of your nose. Remove oils, moisturizers — adhesive needs dry skin to stick. breatheright.com
- Choose the right size: many brands offer small/medium and large — pick the size that fits your nose width. breatheright.co.uk
- Positioning: place the strip centered across the nose so the flexible bands lie just above each nostril (over the nasal valve area), not higher on the bridge or too low. The goal is for the strip’s springs to lift the sidewalls. breatheright.com
- Press firmly: press the ends and center for ~10 seconds so the adhesive bonds.
- Use at bedtime: apply before sleep and remove in the morning by easing off from the sides toward the center; if resistant, warm water or oil can help remove adhesive without skin injury. breatheright.com+1
- Single use: strips are intended for single-night use (disposable). Replace nightly. breatheright.com.au

Practical tips:
- Try a few nights to find optimal placement — a small shift can matter.
- If you wake and still snore heavily or feel unrefreshed, ask a clinician about a sleep study — don’t assume strips fixed OSA.
- Internal nasal dilators (inserted into the nostrils) can work better than external strips for some people; published comparisons exist. rhinologyjournal.com
Scientific Evidence for Sleep Apnea:
Systematic reviews / meta-analyses
- Camacho et al., Pulmonary Medicine (systematic review & meta-analysis): reviewed external (Breathe Right) and internal (NoZovent) dilators for snoring/OSA — overall evidence shows improvement in nasal obstruction and snoring in selected patients but limited impact on objective OSA severity across studies. JCSM
Randomized / controlled / exploratory clinical trials
- Amis et al. / Springer (2019) — "Objective and Subjective Effects of a Prototype Nasal Dilator Strip": exploratory trial reported reductions in nasal resistance and some measures of sleep-disordered breathing in people with chronic nocturnal nasal congestion, but the study was small/exploratory and not definitive. SpringerLink
- Allergy, Asthma & Clinical Immunology (2018) — randomized, double-blind trial comparing marketed Breathe Right to a prototype and placebo strips: found subjective improvements in congestion and sleep quality compared with placebo in people with chronic nasal congestion. BioMed Central
Important negative / comparison findings
- J Clin Sleep Med (AASM) — nasal dilator as placebo in severe OSA trials: studies have shown nasal strips often do not change polysomnographic measures (sleep architecture, respiratory events) in severe OSA and have been used as a placebo comparator against CPAP. This supports the conclusion that nasal strips are usually not an effective alternative to CPAP for moderate-to-severe OSA. JCSM
Summary: external nasal strips reliably reduce nasal resistance and help people whose problems are nasal-obstruction driven (subjective relief, less snoring). But the objective effect on apnea-hypopnea index (AHI) is inconsistent and generally small; they are not a substitute for PAP therapy in patients with moderate-to-severe OSA. For selected mild OSA or positional/snoring cases with nasal obstruction, strips may help as an adjunct or temporary measure. Wiley Online Library
Specific Warnings for Sleep Apnea:
Not a reliable treatment for moderate/severe OSA: if you have diagnosed moderate or severe OSA, relying on nasal strips instead of guideline therapies (CPAP/oral appliance/surgery when indicated) can leave you untreated and at risk for cardiovascular, metabolic, and daytime performance harms. Follow AASM guidance: PAP is preferred first-line for OSA unless alternatives are appropriate. JCSM
May give false reassurance: strips can reduce snoring or congestion but may not reduce apneic events — don’t substitute them for diagnostic evaluation and recommended therapy if OSA is suspected. Verywell Health
Skin reactions / irritation: adhesive can cause redness, dermatitis, or injury when removed (especially fragile skin). Follow manufacturer advice for removal and avoid on broken skin. See product insert for contraindications (example Breathe Right product insert). breatheright.com.au
Not for certain nasal blockages: mechanical strips help the external nasal valve. They are less effective for obstruction located deeper inside the nose/sinuses (large polyps, severe septal deviation) — ENT assessment may be needed. rhinologyjournal.com
Caution with children and certain conditions: check product labeling for age limits; if you have dermatologic conditions, skin fragility, or severe nasal anatomical problems, consult a clinician. Manufacturer leaflets list age/usage guidance. breatheright.com.au
Drug interactions irrelevant but medical therapies exist: nasal strips are drug-free. If you’re using topical nasal decongestants, be aware of rebound congestion risks from prolonged decongestant sprays (NICE guidance). Use strips as an adjunct, not a substitute for medical advice. cks.nice.org.uk
General Information (All Ailments)
What It Is
A nasal dilator strip is a small, adhesive device designed to be applied externally across the bridge of the nose. It is typically made of flexible plastic or spring-like bands embedded in a soft, breathable material. These strips are non-invasive and commonly used to help improve nasal airflow during sleep, exercise, or times of nasal congestion. They are often marketed as over-the-counter aids for snoring, sleep quality, and breathing difficulties caused by colds or allergies.
How It Works
Nasal dilator strips function through mechanical dilation. When applied correctly, the adhesive anchors the strip to the sides of the nose. The embedded spring-like bands attempt to return to their original straight shape, gently lifting and expanding the nasal passages (specifically, the nasal valve area). This mechanical action reduces airflow resistance, allowing air to pass more freely through the nostrils.
By physically widening the nasal passages, the strips reduce the effort required to inhale through the nose, which can:
- Enhance oxygen intake during sleep or exercise.
- Alleviate congestion from colds or allergies.
- Diminish snoring caused by restricted nasal airflow.
Importantly, nasal strips act only externally and do not deliver medication or affect deeper nasal structures like the turbinates or sinuses.
Why It’s Important
Nasal dilator strips play a valuable role in supporting respiratory comfort and sleep quality, particularly for individuals with mild nasal obstruction. They are important because they provide a drug-free, non-invasive solution to breathing difficulties, offering several health and quality-of-life benefits:
- Improved breathing efficiency: By reducing airflow resistance, users can breathe more easily through their nose.
- Enhanced sleep quality: Better nasal airflow can reduce mouth breathing and snoring, potentially improving sleep for both the user and their partner.
- Relief during illness or allergies: Nasal strips can temporarily ease congestion from colds or allergic rhinitis without the side effects of decongestant medications.
- Performance aid in sports: Some athletes use nasal strips to maintain clearer airflow during intense physical activity, which can marginally improve comfort and endurance.
Considerations
While nasal dilator strips are generally safe and easy to use, there are several important considerations to keep in mind:
- Effectiveness varies: They are most effective for individuals whose nasal obstruction is due to external valve collapse or mild structural narrowing. They are less helpful for deeper obstructions or conditions such as severe septal deviation.
- Proper application: For optimal results, the strip must be applied to clean, dry skin across the nasal bridge and sides. Incorrect placement can reduce effectiveness.
- Skin irritation: Some users may experience mild redness or irritation from the adhesive, especially with prolonged or repeated use.
- Temporary solution: Nasal strips offer short-term relief; they do not treat underlying medical causes of chronic congestion or snoring.
- Not a substitute for medical evaluation: Persistent nasal obstruction, snoring, or breathing issues may indicate conditions such as sleep apnea, which require professional assessment and potentially different interventions.
