Several effective alternatives to CPAP exist for treating sleep apnea, ranging from oral devices and positional training to implanted nerve stimulators and targeted exercises. CPAP remains the most powerful tool for reducing breathing interruptions during sleep, but somewhere between 40 and 60 percent of patients struggle to tolerate it, which has driven decades of research into other options. The right alternative depends on the type and severity of your apnea, your body, and what you can realistically stick with over years of nightly use.
Oral Appliances
Oral appliances are the most widely studied CPAP alternative and the one your sleep specialist is most likely to recommend first. The most common type is a mandibular advancement device, a custom-fitted mouthpiece that holds your lower jaw slightly forward during sleep to keep the airway open. Head-to-head comparisons consistently show that these devices do not reduce breathing interruptions as much as CPAP does on paper. But here is the catch: people actually wear them. One five-year study found that patients using a mandibular advancement device wore it an average of about 7.3 hours per night, compared with roughly 5 hours for CPAP users.1Journal of Oral Rehabilitation. Long‐Term Therapeutic Efficacy of Mandibular Advancement Device Compared to Continuous Positive Airway Pressure in Patients With Obstructive Sleep Apnea That gap in nightly use largely erases CPAP’s superiority in controlled settings, so real-world health outcomes end up looking similar between the two treatments.2PubMed Central. Oral Appliances in Obstructive Sleep Apnea A systematic review confirmed that while CPAP is better at reducing the raw number of breathing events, mandibular advancement devices deliver meaningful improvements in sleep quality, cognitive function, and patient compliance.3Journal of Sleep Research. Comparative Efficacy of Continuous Positive Airway Pressure and Mandibular Advancement Devices in the Treatment of Obstructive Sleep Apnea: A Systematic Review
A separate meta-analysis looking at quality-of-life scores, cognitive performance, and daily functioning found no statistically significant difference between CPAP and oral appliance users on any of those measures, despite CPAP’s edge in raw breathing-event reduction. Nightly compliance was about an hour lower with CPAP, which the authors identified as the likely explanation for the similar outcomes.4PubMed. Effects of CPAP and mandibular advancement device treatment in obstructive sleep apnea patients: a systematic review and meta-analysis
A less common option is the tongue-retaining device, a monobloc appliance that holds the tongue forward instead of the jaw. In one study, it achieved a complete or partial response in about 71 percent of patients, with the average number of breathing events per hour dropping from 38 to 14.5PubMed Central. The tongue-retaining device: efficacy and side effects in obstructive sleep apnea syndrome The main drawback is acceptance: only about half of patients were still using one after five years, and people with nasal obstruction tended to abandon it. A separate quasi-experimental study comparing a titrated tongue-stabilizing device with a mandibular advancement device found similar improvements in breathing events, but the tongue device had worse scores for daytime sleepiness and quality of life, and its acceptance rate was low at around 54 percent.6PubMed Central.

Positional Therapy
Many people with sleep apnea have what is called positional obstructive sleep apnea, meaning their breathing events happen mostly or entirely when they lie on their back. Gravity pulls the tongue and soft tissues backward in the supine position, narrowing the airway. If your sleep study shows that your apnea is significantly worse on your back than on your side, positional therapy may be enough on its own.
The simplest version is the tennis ball technique: you attach a tennis ball or similar object to the back of your sleep shirt so rolling onto your back becomes uncomfortable. It works, but people tend to stop doing it. A dedicated wearable device called a sleep position trainer uses vibration to nudge you off your back and has shown better long-term results. In a head-to-head trial, the electronic trainer brought the breathing-event index below 5 events per hour (essentially normal) in 68 percent of patients, compared with about 43 percent for the tennis ball method.7PubMed Central. Sleep Position Trainer versus Tennis Ball Technique in Positional Obstructive Sleep Apnea Syndrome A six-month study of the electronic trainer found that patients maintained near-total avoidance of back sleeping, and daytime sleepiness, sleep quality, and functional outcomes all improved. Compliance with the device was about 64 percent when defined as more than four hours of use per night.8PubMed Central. Long-term effectiveness and compliance of positional therapy with the sleep position trainer in the treatment of positional obstructive sleep apnea syndrome
A systematic review and meta-analysis confirmed that positional therapy reduces both the breathing-event index and the time spent sleeping on your back, though CPAP still outperforms it in terms of raw breathing-event reduction.9PubMed. Positional modification techniques for supine obstructive sleep apnea: A systematic review and meta-analysis Positional therapy is best suited for mild to moderate cases where supine sleep is the main problem. If your apnea is severe or happens in all sleep positions, this alone will not be enough.
Hypoglossal Nerve Stimulation
For people who cannot tolerate CPAP and have moderate to severe obstructive sleep apnea, an implanted nerve stimulator is one of the more dramatic alternatives. Approved in 2014, the device (best known under the brand name Inspire) is surgically placed under the skin of the chest and neck. It monitors your breathing pattern and delivers mild electrical pulses to the hypoglossal nerve, which controls the tongue. Each pulse stiffens and gently pushes the tongue forward in sync with your inhalation, keeping the airway open.10PubMed Central. Hypoglossal Nerve Stimulation Therapy for the Treatment of Obstructive Sleep Apnea
An updated meta-analysis found that the Inspire device reduced the breathing-event index by about 20 events per hour in the short term and about 16 events per hour over the long term. Daytime sleepiness scores dropped substantially and functional sleep outcomes improved, with those benefits holding over years of follow-up.11PubMed. Hypoglossal nerve stimulation for obstructive sleep apnea in adults: An updated systematic review and meta-analysis A retrospective study of 30 patients also showed that the device works particularly well in people whose apnea is position-dependent, with the greatest improvements in supine breathing events among those patients.12Journal of Clinical Medicine. Effectiveness of Hypoglossal Nerve Stimulation Therapy in Positional Obstructive Sleep Apnea: A Retrospective Observational Study
The device is not for everyone. Candidates generally need to have failed CPAP, have a body mass index below a certain threshold, and undergo a drug-induced sleep endoscopy to confirm that the pattern of airway collapse is one the stimulator can address. The surgery itself carries the usual risks of any implant procedure, and the device requires periodic battery replacement. But for the right patient, the results have been strong enough that it has moved from experimental to mainstream in sleep medicine.
Myofunctional Therapy and Airway Exercises
Myofunctional therapy refers to a set of exercises that strengthen the tongue, soft palate, and throat muscles. Think of it as physical therapy for your airway. The exercises typically involve repeated tongue presses against the roof of the mouth, cheek muscle contractions, and specific swallowing techniques, practiced daily for several months.
A Cochrane review found that in adults, myofunctional therapy produced a meaningful reduction in the breathing-event index compared with sham therapy and also reduced daytime sleepiness and subjective snoring intensity, though the certainty of the evidence was rated low to moderate.13PubMed Central. Myofunctional therapy (oropharyngeal exercises) for obstructive sleep apnoea An earlier meta-analysis estimated that myofunctional therapy cut the breathing-event index by roughly half in adults and improved oxygen levels during sleep as well.14SLEEP. Myofunctional Therapy to Treat Obstructive Sleep Apnea: A Systematic Review and Meta-analysis Most researchers frame this as an adjunct therapy rather than a standalone cure, since it does not eliminate apnea entirely, and its effectiveness depends on whether you keep doing the exercises.
An unusual but surprisingly well-studied version of airway exercise is didgeridoo playing. A randomized controlled trial found that four months of regular didgeridoo practice reduced daytime sleepiness and the breathing-event index, and partners reported less sleep disturbance.15PubMed Central. Didgeridoo playing as alternative treatment for obstructive sleep apnoea syndrome: randomised controlled trial The circular breathing technique required to play the instrument appears to work the upper airway muscles in much the same way as formal myofunctional therapy. A systematic review confirmed the positive effect of didgeridoo on apnea severity and sleepiness, though the total body of evidence remains small.16PubMed Central.

Weight Loss
Excess weight is the single biggest modifiable risk factor for obstructive sleep apnea. Fat deposits around the neck and tongue narrow the airway, and abdominal fat reduces lung volume, making the airway more collapsible during sleep. Losing weight can substantially reduce apnea severity, though it rarely eliminates it altogether.
A meta-analysis of dietary weight-loss programs found that the average breathing-event index dropped from about 52.5 to 28.3 events per hour after weight loss. Compared with control groups, dieting reduced events by about 14 per hour. The authors concluded that weight-loss programs are effective at reducing severity but should be considered an adjunct to other treatment rather than a standalone cure.17PubMed. Effects of dietary weight loss on obstructive sleep apnea: a meta-analysis A more recent systematic meta-analysis found that a 20 percent reduction in body mass index was associated with roughly a 57 percent drop in breathing events, though the relationship became less predictable at higher levels of weight loss.18PubMed Central. Weight reduction and the impact on apnea-hypopnea index: A systematic meta-analysis Ten-year follow-up data from a large lifestyle-intervention study showed that for every kilogram of weight lost, the breathing-event index fell by about 0.7 events per hour, and this benefit persisted over the full decade.19PubMed Central. Weight Loss Is Integral to Obstructive Sleep Apnea Management. Ten-Year Follow-up in Sleep AHEAD
For people with severe obesity, bariatric surgery produces more dramatic and durable results. A 20-year follow-up from the Swedish Obese Subjects study found that bariatric surgery was associated with a roughly 32 percentage-point lower prevalence of sleep apnea compared with standard obesity care, including higher remission rates and lower rates of new-onset apnea.20Obesity. Obstructive Sleep Apnea Following Bariatric Surgery: 20 Year Outcomes From the Swedish Obese Subjects Study That said, sleep apnea persists after bariatric surgery in a substantial number of patients. A narrative review found remission rates varied widely, from 24 to 74 percent across studies, with severe pre-operative apnea and less total weight loss predicting persistence.21Nature and Science of Sleep. Factors Associated with Persistent Obstructive Sleep Apnea After Bariatric Surgery: A Narrative Review
Surgical Approaches to the Airway
When the anatomy of your jaw or palate is a major contributor to airway collapse, surgery aimed directly at the structure of the airway can be effective. Maxillomandibular advancement is one of the most aggressive options: it surgically moves both the upper and lower jaw forward to permanently enlarge the airway space behind the tongue. A meta-analysis found that this procedure reduced the breathing-event index by an average of about 80 percent, and nearly 99 percent of patients showed improvement. Most of the patients in the studies had already tried other surgeries for their apnea without adequate success.22PubMed. Maxillomandibular Advancement for Treatment of Obstructive Sleep Apnea: A Meta-analysis This is a major operation with significant recovery time, facial swelling, and potential changes to your bite, so it is generally reserved for cases where less invasive options have failed or where skeletal anatomy is clearly the main problem.
Rapid maxillary expansion is a different structural approach, used mostly in children with sleep apnea related to a narrow palate. A study following children for 36 months after expansion found that the breathing-event index decreased and clinical symptoms resolved by the end of treatment, with improvements holding steady at the two-year mark.23PubMed. Efficacy of rapid maxillary expansion in children with obstructive sleep apnea syndrome: 36 months of follow-up In adults, a surgically assisted version of the same procedure has also shown improvement in breathing events, oxygen desaturation, and sleepiness scores.24Evidence-Based Dentistry. Does surgically assisted maxillary expansion improve obstructive sleep apnoea in adults? A systematic review and meta-analysis
Emerging Drug Treatments
There is currently no FDA-approved medication specifically for obstructive sleep apnea, but several drugs are in active investigation. The most promising candidate as of recent trials is sulthiame, a carbonic anhydrase inhibitor originally developed as an anticonvulsant. In a randomized controlled trial, sulthiame reduced the breathing-event index by about a third at the 200-milligram dose and nearly 40 percent at the 400-milligram dose, compared with only about 5 percent for placebo.25American Journal of Respiratory and Critical Care Medicine. A Randomized Controlled Clinical Trial Exploring Safety and Tolerability of Sulthiame in Sleep Apnea These are early-stage results, and larger trials are still needed.
Acetazolamide, another carbonic anhydrase inhibitor, has also shown some ability to reduce breathing events and lower blood pressure in patients with both sleep apnea and hypertension. In a randomized trial, it reduced the breathing-event index and lowered mean arterial pressure by about 7 mmHg, effects that were not seen with CPAP alone in the same trial.26PubMed Central. Acetazolamide Reduces Blood Pressure and Sleep-Disordered Breathing in Patients With Hypertension and Obstructive Sleep Apnea: A Randomized Controlled Trial A trial of dronabinol, a synthetic cannabinoid, found dose-dependent reductions in breathing events as well, with the higher dose lowering the index by about 13 events per hour compared with placebo and improving daytime sleepiness.27PubMed Central. Pharmacotherapy of Apnea by Cannabimimetic Enhancement, the PACE Clinical Trial: Effects of Dronabinol in Obstructive Sleep Apnea None of these drugs are ready for routine clinical use yet, but they represent genuine progress toward a pill-based option.
Oxygen Therapy for Central Sleep Apnea
Central sleep apnea is a different condition from the more common obstructive type. Instead of a physical blockage, the brain temporarily fails to send the signal to breathe. It is particularly common in people with heart failure. For central apnea, supplemental oxygen delivered through nasal cannula during sleep can be quite effective. One study found that nocturnal oxygen reduced the number of central breathing events from a median of about 33.5 to 5 per hour, with more than 85 percent of patients seeing at least a 50 percent reduction.28PubMed. Reversal of central sleep apnea with oxygen
In patients with heart failure specifically, a trial of home oxygen therapy found that it significantly reduced the breathing-event index by about 11 events per hour compared with no treatment and was associated with improvements in exercise capacity, functional class, and heart function.29PubMed. Effects of nocturnal oxygen therapy in patients with chronic heart failure and central sleep apnea: CHF-HOT study A more recent sham-controlled trial in heart failure patients confirmed improvements in sleep-disordered breathing and overnight oxygenation, although the trial was terminated early and could not demonstrate broader clinical effectiveness.30Annals of the American Thoracic Society. Nocturnal Oxygen Therapy for Central Sleep Apnea in Patients with Heart Failure: A Multisite, Double-Blind, Sham-controlled Randomized Clinical Trial (LOFT-HF) Supplemental oxygen does not work well for obstructive sleep apnea, where the problem is a physical collapse rather than a signaling failure.
What About Nasal Strips and Nasal Dilators?
Nasal strips and internal nasal dilators are cheap and widely available, which naturally makes people wonder whether they can treat sleep apnea. A systematic review and meta-analysis tested this directly and found that while these products improve the feeling of nasal airflow, they do not meaningfully change the breathing-event index, oxygen levels, or snoring index in people with sleep apnea. Internal dilators (the kind you insert inside the nostril) showed a slight reduction in the apnea index specifically, but external adhesive strips produced essentially no change.31Pulmonary Medicine. Nasal Dilators (Breathe Right Strips and NoZovent) for Snoring and OSA: A Systematic Review and Meta-Analysis If you snore but do not have obstructive sleep apnea, nasal strips might help. If you have diagnosed apnea, they are not a treatment.
Acupuncture
Acupuncture has been studied as a potential sleep apnea treatment, mainly in trials from East Asia. A meta-analysis of nine randomized controlled trials with 584 participants found that acupuncture reduced the breathing-event index by about 6 events per hour overall and improved daytime sleepiness scores. In subgroup analyses of people with moderate or severe apnea, the reductions were larger, around 9 to 10 events per hour.32PubMed Central. Acupuncture for Obstructive Sleep Apnea (OSA) in Adults: A Systematic Review and Meta-Analysis These numbers are worth noting, but the quality of the included trials was generally low, blinding was difficult, and the results have not been replicated in large Western clinical settings. Acupuncture is unlikely to be harmful, but the evidence is not strong enough to recommend it as a primary treatment.
Treating Insomnia Alongside Sleep Apnea
A frustrating pattern many patients experience is having both sleep apnea and insomnia at the same time. Doctors call this comorbid insomnia and sleep apnea, and it creates a treatment dilemma: CPAP can be even harder to tolerate when you already struggle to fall or stay asleep, but untreated apnea worsens insomnia. Research has shown that adding cognitive behavioral therapy for insomnia alongside CPAP produces faster improvements in both sleep and daytime functioning than either treatment alone.33PubMed Central. A randomized controlled trial of cognitive behavioral therapy for insomnia and PAP for obstructive sleep apnea and comorbid insomnia: effects on nocturnal sleep and daytime performance Randomized trials have provided evidence supporting this combined approach, and recent clinical guidance increasingly recommends addressing both conditions simultaneously rather than treating the apnea first and hoping the insomnia resolves on its own.34PubMed Central.

Why Humans Are Uniquely Vulnerable to Sleep Apnea
It is worth understanding why sleep apnea is so common in the first place. The condition is essentially a byproduct of human evolution. The anatomical changes that made speech possible, including a shortened jaw, a descended larynx, and a tongue that sits further back in the throat, also created a collapsible airway that no other primate shares to the same degree.35Sleep Medicine. The Great Leap Forward: the anatomic basis for the acquisition of speech and obstructive sleep apnea Modern diets that require less chewing may have further reduced jaw size over recent centuries, compounding the problem. This evolutionary framing matters because it explains why so many different treatments exist and why none of them is perfect: there is no single fix for a vulnerability built into the basic shape of the human throat. The diversity of alternatives reflects the diversity of anatomical reasons someone’s airway collapses during sleep, and the best approach usually involves matching the treatment to the specific mechanism at work in your case.
