Sleep apnea is highly treatable, and your options range from a pressurized mask worn at night to lifestyle changes, oral devices, positional aids, and surgery. The right approach depends on how severe your condition is, what’s causing the airway obstruction, and what you can realistically stick with long term. Most people with obstructive sleep apnea, the most common type, will find significant improvement with at least one of these strategies.
How Severity Shapes Your Options
Sleep apnea severity is measured by the apnea-hypopnea index (AHI), which counts how many times per hour your breathing partially or fully stops during sleep. Harvard Medical School classifies the levels as: mild (5 to 14 events per hour), moderate (15 to 29), and severe (30 or more). Below 5 is considered normal. Your AHI matters because it directly influences which treatments are recommended and how aggressively they need to work.
Someone with mild sleep apnea and position-dependent breathing problems may do well with a simple wearable device or a mouthpiece. Someone with severe sleep apnea, where breathing stops 30 or more times an hour, typically needs CPAP or a surgical intervention to bring those numbers into a safe range.
CPAP: The Most Effective Standard Treatment
Continuous positive airway pressure (CPAP) remains the gold standard for obstructive sleep apnea. The machine delivers a steady stream of pressurized air through a mask, keeping your airway open throughout the night. Studies show CPAP reduces the AHI by about 73% on average. For people with severe sleep apnea who wear the device at least six hours per night, AHI typically drops back to normal levels, below five events per hour.
The catch is adherence. Many people struggle with the mask, the noise, the dryness, or the feeling of forced air. Modern CPAP machines are quieter and lighter than older models, and options like heated humidifiers, different mask styles (nasal pillows, full face, nasal cradle), and auto-adjusting pressure settings have made the experience more tolerable. If your first mask is uncomfortable, it’s worth trying alternatives before giving up on CPAP entirely, because nothing else matches its raw effectiveness.
The cardiovascular stakes are real. Untreated sleep apnea repeatedly drops your blood oxygen levels overnight, which over time raises your risk of high blood pressure and diabetes. Consistent CPAP use reverses that pattern, though the cardiovascular benefit appears strongest in people who also experience daytime sleepiness, not just those with a high AHI alone.
Oral Appliances
If you can’t tolerate CPAP or have mild to moderate sleep apnea, a mandibular advancement device (MAD) is the main alternative. These custom-fitted mouthpieces push your lower jaw slightly forward, which tightens the soft tissue at the back of your throat and keeps the airway more open. They’re smaller, quieter, and easier to travel with than a CPAP machine.
A five-year study published in the Journal of Clinical Sleep Medicine tracked long-term outcomes and found that 52% of patients overall maintained treatment success (defined as at least a 50% drop in AHI). Interestingly, the device worked better for more severe cases: success rates were 63% for severe OSA, 52% for moderate, and only 25% for mild. However, these numbers declined over time. At the three-to-six-month mark, 79% of patients hit the success threshold. By two years, that dropped to 68%, and by five years, 52%. This gradual decline suggests follow-up sleep studies are important to make sure the device is still doing its job.
You’ll need a dentist or sleep specialist to fit the appliance, and it may take a few adjustments to get the jaw position right. Common side effects include jaw soreness, excessive salivation, and changes in bite over time.
Positional Therapy
Many people have sleep apnea that’s significantly worse when lying on their back. Gravity pulls the tongue and soft palate backward, narrowing the airway. If your AHI drops by 50% or more when you sleep on your side compared to your back, you have what’s called positional obstructive sleep apnea, and positional therapy may be enough on its own.
The simplest version is the tennis ball technique: attaching something bulky to the back of your sleep shirt so rolling onto your back becomes uncomfortable. In one study, this approach was effective in about 43% of patients. More sophisticated options include small wearable devices that vibrate gently when you roll onto your back, nudging you to shift without fully waking you. These electronic devices perform better. In a head-to-head comparison, the vibrating devices achieved treatment success (AHI below 5) in 68% of patients, compared to 43% for the tennis ball method. One study found these devices reduced AHI from 25 events per hour down to about 14.
Positional therapy also compares favorably to oral appliances in some research. One study found no significant difference between the two for reducing AHI, though the positional device produced better sleep continuity with fewer nighttime arousals.
Upper Airway Stimulation Surgery
For people who can’t use CPAP and have moderate to severe obstructive sleep apnea, upper airway stimulation (often known by the brand name Inspire) is a surgically implanted device. A small generator placed under the skin in the chest sends mild electrical pulses to the nerve that controls the tongue, keeping it from collapsing backward during sleep. You turn it on with a remote before bed.
In clinical trials reported by the Mayo Clinic, the device reduced AHI by 68%, bringing the average from 29.3 events per hour down to 9.0 at the 12-month mark. Two-thirds of patients achieved at least a 50% reduction in AHI with a final score under 20 events per hour. These results held up at three and five years of follow-up. The surgery itself is outpatient, and most people recover within a few days, though not everyone qualifies. Candidates typically need a BMI under 35 and must have a specific pattern of airway collapse confirmed by a brief scope procedure.
Weight Loss and Exercise
Excess weight is the single biggest modifiable risk factor for obstructive sleep apnea. Fat deposits around the neck and throat narrow the airway, and abdominal fat pushes the diaphragm upward, reducing lung volume. Losing even 10% of body weight can meaningfully reduce AHI in many people, and in mild cases, it can resolve sleep apnea entirely.
Exercise also helps independent of weight loss. Regular aerobic activity improves the muscle tone of the upper airway and reduces fluid retention in the neck. Some studies show that exercise programs lower AHI even when participants don’t lose significant weight. That said, weight loss alone is rarely enough for moderate or severe sleep apnea. It works best as a complement to other treatments, potentially allowing you to lower your CPAP pressure or eventually transition to a less intensive therapy.
Avoiding Alcohol and Sedatives
Alcohol relaxes the muscles in the throat, which narrows the airway and makes collapse more likely during sleep. It also delays the brain’s arousal reflex, the mechanism that briefly wakes you to reopen the airway when breathing stops. The result: breathing pauses happen more often, last longer, and drive oxygen levels lower. If you use a CPAP machine, alcohol can also undermine treatment by requiring higher pressure settings to keep the airway open.
Sedative medications, including certain sleep aids and muscle relaxants, have a similar effect. If you have sleep apnea and regularly drink in the evening, cutting back or stopping alcohol within three to four hours of bedtime is one of the simplest changes you can make. It won’t cure sleep apnea, but it can noticeably reduce the severity of nighttime breathing disruptions.
Combining Approaches
Sleep apnea treatment doesn’t have to be all-or-nothing. Many people get the best results by layering strategies. Using CPAP alongside weight loss, for example, can reduce the pressure setting you need and make the mask more comfortable. Combining positional therapy with an oral appliance can cover both the gravity-related and the tissue-related components of airway collapse. If you’re starting treatment, the goal is finding a combination you’ll actually use consistently, because even the most effective therapy does nothing sitting on your nightstand.
