If you’ve been diagnosed with mild obstructive sleep apnea (OSA), or you snore night after night, you’ve probably heard about CPAP therapy and the mask worn during sleep. For many people, that’s exactly what works. For others, wearing the mask is one reason they’ve put off treatment, struggled through tired mornings, or given up on therapy altogether.
That hesitation is common, and it’s worth taking seriously. So let’s answer the question a lot of people are really asking: Is there a way to treat sleep apnea without wearing a mask at night?
Can Sleep Apnea Be Treated Without a Mask?
For some people, yes. Adults with mild obstructive sleep apnea may be candidates for non-mask treatment options, including eXciteOSA®, a daytime therapy used while awake rather than a device worn during sleep.
The right treatment depends on your diagnosis, OSA severity, health history, and provider’s recommendation. One important measurement is your apnea-hypopnea index, or AHI. eXciteOSA is authorized for adults with mild OSA and snoring, not for moderate or severe sleep apnea. No article can tell you whether it’s appropriate for you, but a sleep provider can help you find out.
If you’ve struggled with a mask and you’re looking for a daytime option, learn more about eXciteOSA through Rotech Healthcare.

What Is eXciteOSA®?
eXciteOSA is a small, mask-free mouthpiece used for about 20 minutes once a day during the initial treatment period. Instead of using air pressure to hold the airway open while you sleep, it works during the day to stimulate the tongue muscles and improve muscle function.
It was authorized by the FDA in 2021 as the first device used while awake that’s intended to improve tongue muscle function. Over time, this may help keep the tongue from collapsing backward and obstructing the airway during sleep. It’s a prescription therapy for adults 18 and older with snoring and mild OSA.
How Does eXciteOSA Work?
The idea behind eXciteOSA comes from one factor that can contribute to mild OSA and snoring — reduced tongue muscle endurance or tone.
When the upper-airway muscles relax during sleep, the airway can narrow or collapse. The tongue may contribute to that obstruction, leading to snoring or brief breathing interruptions.
eXciteOSA uses neuromuscular electrical stimulation, or NMES, to stimulate the tongue muscles. The medical-grade silicone mouthpiece sits around the tongue and delivers gentle electrical pulses through flexible electrodes. Each daily session consists of four five-minute phases that use different stimulation frequencies. During use, you may feel mild contractions or tingling as the stimulation intensity is adjusted.
NMES itself isn’t new. It’s been used in other healthcare settings to improve muscle function. What’s different here is the application of NMES to the tongue during the day, with the goal of improving tongue muscle function and endurance.
What Is NMES?
Neuromuscular electrical stimulation uses gentle electrical pulses to activate specific muscles.
The goal is to improve tongue muscle endurance during the day so the tongue is less likely to contribute to a blocked airway during sleep.

How Often Do You Use eXciteOSA?
This is the part that tends to catch people’s attention. There’s nothing to wear overnight — no mask, no hose, and no machine running by the bed. You use eXciteOSA for roughly 20 minutes a day while you’re awake, which is why many people can fit it into an ordinary part of their routine.
The FDA-authorized treatment schedule looks like this:
- One 20-minute session each day
- Daily use for the first six weeks
- Once-weekly maintenance use after the initial six weeks
Always follow the current instructions supplied with your device and the directions from your healthcare professional. Don’t change the recommended schedule based only on general information found online.
The eXciteOSA app connects to the device through Bluetooth. It activates your treatment sessions, controls intensity, and helps you monitor your progress.
Results develop gradually, so consistent use and appropriate follow-up are important.

What Results Have Been Reported?
In the clinical information cited by Rotech, researchers reported:
- 90% of patients reported reduced snoring
- 79% of patients with mild OSA responded to therapy
- 52% average reduction in AHI after therapy
- Results reported after an initial six-week treatment period
These figures come from the studies behind eXciteOSA and don’t guarantee the same outcome for every user. Individual results can vary. Follow-up testing is still important to confirm that the therapy is working, both when you begin and over time.

Who May Be a Candidate for eXciteOSA?
eXciteOSA may be worth asking about if snoring or mild OSA is affecting your sleep and wearing a mask has been a barrier to treatment. Whether it’s right for you depends on your diagnosis, AHI, medical history, oral health, and provider’s recommendation.
eXciteOSA may be worth discussing with a sleep provider if you:
- Are 18 or older
- Have primary snoring or diagnosed mild obstructive sleep apnea
- Have an AHI below 15
- Have struggled to use PAP therapy consistently
- Have avoided treatment because you do not want to wear a mask at night
- Are willing to follow the initial treatment and maintenance schedule
- Can complete the recommended clinical and dental screening
A sleep test matters here, because snoring alone can’t tell you whether you have OSA or how severe it may be. Someone with moderate or severe OSA may need a different treatment approach.

If you already have an eXciteOSA prescription, you can review the eXciteOSA Starter Kit through ShopRotech. It’s prescription-required and FSA/HSA eligible, subject to your plan’s requirements.
Who Shouldn’t Use eXciteOSA?
eXciteOSA isn’t intended for people who have, or are suspected of having, moderate or severe sleep apnea with an AHI of 15 or higher.
Based on the FDA review, it’s also not recommended for certain patients, including people who:
- Are pregnant
- Have a pacemaker or implanted electrodes
- Have mouth ulcerations
- Are under age 18
- Have other contraindications identified in the current device labeling
Some earlier dental and oral limitations were updated in a later FDA clearance. Eligibility can depend on your oral health, implanted devices, other medical factors, and the current device instructions. Your healthcare provider can help determine which evaluations you need before starting.
Refer to the current device instructions for the complete list of warnings, precautions, and contraindications.

eXciteOSA vs. CPAP
CPAP and eXciteOSA approach obstructive sleep apnea differently. Neither option is universally better, and they shouldn’t be treated as interchangeable.
CPAP
Continuous positive airway pressure delivers pressurized air through a mask while you sleep, and that air pressure helps keep the throat open. CPAP is a common, well-established treatment for OSA and may be prescribed across different levels of severity.

eXciteOSA
eXciteOSA is used while awake and doesn’t deliver air pressure. Instead, it uses NMES to stimulate the tongue muscles. It’s authorized specifically for reducing snoring and mild OSA in adults.
Put simply, CPAP supports the airway while it’s being worn at night. eXciteOSA provides daytime tongue-muscle stimulation for eligible adults with snoring or mild OSA.
The right treatment depends on your diagnosis, OSA severity, health history, preferences, and provider’s clinical recommendation.
Don’t Stop CPAP Without Talking to Your Provider
If you’ve been prescribed CPAP, APAP, BiLevel, or another PAP therapy, keep using it as directed unless your healthcare provider changes your treatment plan.
Don’t stop PAP therapy because eXciteOSA sounds more convenient or because you believe your symptoms have improved. Untreated or undertreated OSA can affect daytime function and long-term health. A provider should determine whether another therapy is appropriate and whether follow-up sleep testing is needed.
If mask discomfort is what’s keeping you from using prescribed PAP therapy, contact your equipment team or sleep provider. A different mask, a fit adjustment, a comfort setting, or other support may be all it takes.
