Anti-Snoring Remedies, Ranked by How Much Evidence Sits Behind Them
Fourteen common snoring remedies sorted into three tiers — well evidenced, plausible and low risk, and popular but unsupported. The free ones are near the top.
The market for snoring remedies is enormous and almost entirely unregulated, which means the loudest products are not the best-supported ones. This page sorts the common options by the strength of the evidence behind them rather than by how heavily they are advertised.
Three tiers, defined plainly:
- Tier 1 — well evidenced. Randomised trials, meta-analyses, or consistent clinical guidance.
- Tier 2 — plausible and low risk. A real mechanism and some supporting data, but thin, mixed or small studies. Unlikely to harm you.
- Tier 3 — popular but unsupported. Widely sold, no good evidence.
One caveat before the list: none of this applies if you have untreated obstructive sleep apnea. Check that first with the symptom comparison.
Tier 1 — well evidenced
1. Sleeping off your back
The best-supported intervention for snoring is also free. In supine sleep, gravity moves the tongue and soft palate toward the back of the throat, and for a large share of snorers the difference between face-up and side-lying is the difference between constant noise and near silence.
Positional therapy has been studied properly, mostly in positional apnea, where devices that discourage supine sleep reduce event counts substantially. For simple snoring the effect is often larger and more immediate.
The catch is that you cannot decide to stay on your side, because you are unconscious. It has to be enforced mechanically — a vibrating positional trainer worn on the chest or neck, or the cheap version, a tennis ball or a firm pillow secured behind you. Full protocol here.
2. Weight reduction, where excess weight is a contributor
Not a lecture, a mechanism: adipose tissue in the neck and around the pharyngeal walls narrows the airway from the outside, and abdominal fat reduces lung volume in a way that lowers the traction keeping the upper airway stiff.
Weight loss is one of the best-evidenced interventions in the entire sleep-disordered-breathing literature, and modest losses matter. It is also slow, and it does not apply to the substantial number of people with a normal body weight who snore because of jaw position or nasal anatomy. The honest version, including who this does not apply to.
3. Mandibular advancement devices, properly fitted
For tongue-based snoring — the type that passes the jaw-thrust test — advancing the lower jaw is mechanically the right answer, and the trial data supports it. Dentist-fitted, titratable appliances outperform boil-and-bite versions from a pharmacy on both efficacy and side effects.
They are not free of downsides: jaw discomfort, altered bite in the morning, excess salivation, and in a minority of long-term users permanent occlusal change. Those are manageable with a dentist involved and unmanaged without one. What they are and how fitting works.
4. Treating nasal obstruction
If you cannot breathe through your nose, no other remedy performs. Nasal obstruction — allergic rhinitis, chronic rhinosinusitis, a deviated septum, turbinate hypertrophy — raises upstream resistance and forces mouth breathing.
Intranasal corticosteroids for allergic rhinitis are well evidenced and, in that population, improve snoring as a downstream effect. Septal and turbinate surgery is effective for the anatomical cases. What is not supported is treating a structural blockage with an over-the-counter spray indefinitely. Where to start.
5. Reducing alcohol before bed
Alcohol relaxes the dilator muscles of the pharynx, and the effect is dose-dependent and predictable enough that it is used experimentally to induce snoring. It also suppresses the arousal response, so obstructive events last longer.
The practical version is about timing more than abstinence: the closer the last drink is to sleep onset, the worse the effect. The timeline, in detail.
6. Oropharyngeal exercises
Also called myofunctional therapy — a set of tongue, soft palate and pharyngeal exercises performed daily. Randomised trials have found meaningful reductions in snoring intensity and frequency, particularly for palatal snorers.
They cost nothing, they carry no risk, and they require about ten minutes a day for three months before the effect is clear. That last part is why most people never find out whether it would have worked. The routine.
Tier 2 — plausible and low risk
7. Nasal dilators, external and internal
Adhesive strips across the bridge of the nose and stents worn inside the nostrils both work on the nasal valve, the narrowest point of the nasal airway. The mechanism is real and measurable — they reduce nasal resistance.
Whether that translates into less snoring depends entirely on whether your snoring is nasal in origin. In the right subgroup, results are good. Across unselected snorers, the trial results are mixed, which is what you would expect from an intervention that addresses one of four possible causes. The cheek-pull test from the snorer typing guide predicts responders reasonably well, and internal dilators generally outperform external strips in comparative testing.
8. Mouth taping, for confirmed nasal breathers
Holding the lips together overnight prevents the mouth-open posture that drops the jaw, retracts the tongue and destabilises the soft palate. The mechanism is straightforward. The evidence base is small — a handful of studies, mostly in mild sleep-disordered breathing, generally finding modest improvement in snoring and mouth breathing.
The safety condition is not optional: your nose must be clear. Anyone with significant nasal obstruction, or with untreated moderate-to-severe apnea, should not tape. Materials matter too, because eight hours of adhesive on the face is a skin question — Titan Recovery's bamboo silk tape publishes independent lab testing on the adhesive, which is more than most of the category does. The Natural Sleep Lab has a longer treatment of the safety questions if you want the detail before trying it.
9. Positional pillows and wedges
Elevating the head of the bed by ten to fifteen degrees improves airway patency modestly, and there is reasonable physiological support for it. Purpose-built "anti-snoring pillows" that claim to reposition the neck are a weaker proposition — the concept is sound, the specific products are mostly untested, and a wedge under the mattress achieves the elevation for less. The category assessed.
10. Treating reflux, where present
Nocturnal gastro-oesophageal reflux irritates the pharyngeal tissue and is associated with snoring, and treating it appears to help in that subgroup. Worth pursuing if you have heartburn, an acid taste on waking, or a chronic morning cough. Not worth pursuing speculatively.
11. Humidification
Dry air dries mucosa, and dry mucosa is stickier and more prone to vibration. A humidifier in a dry bedroom is cheap, harmless, and occasionally makes a noticeable difference — usually as a modifier rather than a fix.
Tier 3 — popular but unsupported
12. Anti-snoring sprays and throat oils
Sold in every pharmacy. The claim is that a lubricating or astringent film reduces tissue vibration. The trials that exist are small, industry-adjacent and largely negative, and any effect is measured in minutes rather than hours because you swallow the product. Harmless, and a reliable way to spend money annually.
13. Chin straps
A band under the jaw and over the head, intended to hold the mouth closed. The problem is mechanical: pushing the mandible upward and backward is the opposite of the jaw advancement that helps tongue-based snorers, and the strap does not create nasal patency, so someone who is mouth breathing because their nose is blocked simply fights it. Testing has generally found no meaningful reduction in snoring or apnea indices. The full verdict.
14. Tongue-stabilising devices, bought unsupervised
Suction bulbs that hold the tongue forward. The mechanism is not absurd, and there is some data in apnea, but tolerance is poor — most people abandon them — and they are best considered under supervision if a mandibular device is not an option, rather than as a first purchase.
15. Singing, didgeridoo, and other "airway training" claims
The didgeridoo trial is real and is genuinely interesting: regular playing reduced apnea severity in a small randomised study, presumably by training the same muscles as myofunctional therapy. It is not, however, a general prescription. If you want the muscle effect, do the exercises, which take ten minutes rather than an instrument.
The order to try things in
- Rule out apnea.
- Fix the nose so it works.
- Get off your back and move the last drink earlier.
- Give the exercises three months in the background while you do everything else.
- If the jaw-thrust test changed your sound, see a dentist about a mandibular device.
- If your nose is clear and your mouth still falls open, address that.
- Reassess weight and reflux if they apply.
That sequence puts the free, well-evidenced interventions before the paid, weakly-evidenced ones, which is the opposite of the order the market presents them in.
