The Hidden Truth About CPAP Leak Indicators

For anyone who has spent nights battling a CPAP machine, the biggest frustration often comes down to one word: leaks. Patients are usually told that leaks mean their mask isn’t sealing properly. The machine blinks a warning light or spits out a “mask leak report,” and the next thing the patient does is tighten their straps or swap cushions. But here’s the reality—many of these leak alerts aren’t mask-specific at all. They’re the product of leaks anywhere in the CPAP circuit, and that distinction matters.
Why “Mask Leak” Isn’t Always About the Mask
Modern CPAP units are designed to detect variations in flow during treatment. When the machine senses airflow escaping faster than it should, it generates a report. The problem? The unit doesn’t truly know if the leak is coming from the mask, the tubing, the humidifier chamber, or even a connection point. Most will simply flag it as a “mask leak” and leave the patient guessing.

This isn’t just a wording issue—it creates a false sense of direction. Patients end up over-focusing on getting a tighter seal on their mask, sometimes to the point of pain, when the real leak might be:

1. A cracked or pinholed CPAP hose
2. ⁠A loose humidifier chamber lid
3. ⁠A worn-out swivel connector
4. ⁠A leaky valve or coupling that’s barely noticeable
5. ⁠ The mask is put back together incorrectly
6. ⁠ The patient’s mouth is gushing air throughout the night, which is the most common

In other words, the alert is misleading by design. By labeling every possible leak as a mask issue, the machine is essentially training patients to look in the wrong place first.
Why This Misguidance Matters
When pressure settings are compromised by CPAP leaks, therapy effectiveness goes out the window. Patients experience disrupted sleep, lingering fatigue, and reduced compliance—all because they’re chasing down the wrong culprit. Worse, a patient tightening their mask to correct a supposed “CPAP leak” may actually be creating new problems:

1. Pressure sores from overtight straps
2. ⁠Skin breakdown at the nasal bridge
3. ⁠Claustrophobia and discomfort that discourage use

Meanwhile, the actual circuit leak goes unresolved.
The Bigger Picture: A Systemic Oversight
So why do manufacturers do this? In part, it’s simplicity. Telling patients about “CPAP mask leak” seems easier than explaining the full complexity of the CPAP circuit. But this oversimplification shifts responsibility onto the patient instead of addressing the real engineering gap. Machines have the capability to measure system pressures at multiple points, yet many don’t utilize it. Instead, we end up with vague leak metrics and frustrated patients.
What Patients Should Do
If the machine flags a “CPAP leak” don’t assume the mask is always guilty. Instead:

1. Trying to land on a mask that doesn’t leak is crucial. It’s one of the main attractions to the BLEEP masks like Eclipse and DreamPort
2. ⁠Inspect your hose for cracks, even small ones
3. ⁠Check connectors and couplings for looseness
4. ⁠Ensure the humidifier lid is closed and sealed properly
5. ⁠Rotate parts through replacement per manufacturer schedules

By broadening the focus to the entire circuit, patients reclaim control and avoid the trap of unnecessary mask adjustments.
Moving Toward Better Transparency
CPAP Leak therapy already demands consistency and patience. Misleading alerts only add to the frustration and undermine confidence. It’s time machines stopped blaming the mask alone and gave patients the honest truth: a leak anywhere in the circuit is a leak worth fixing. Patients deserve clarity, not guesswork disguised as data.

What are CPAP leak indicators?

CPAP leak indicators are data points shown in your machine's app or display (like myAir or DreamMapper) that measure how much air escapes around your mask seal each night, reported in litres per minute (L/min).

What is an acceptable CPAP leak rate?

Most CPAP manufacturers consider a leak rate below 24 L/min acceptable for nasal masks and below 36 L/min for full-face masks. Higher leak rates reduce therapy effectiveness and should be addressed.

Why does my CPAP report leaks even though I feel no air escaping?

Small leaks around the mask seal or at the exhalation port are often unnoticeable during sleep. Your CPAP records them because even minor air loss disrupts the pressure needed to keep your airway open.

What causes high CPAP leak readings?

Common causes include a worn or misaligned mask cushion, over-tightened or under-tightened headgear, sleeping position shifting the mask, mouth breathing with a nasal mask, or a mask style that simply does not fit your face shape.

How do I fix CPAP mask leaks?

Start by repositioning your mask while your machine is running to find the seal sweet spot. Replace worn cushions, adjust headgear tension, and consider a mask style better suited to your sleeping position. A headgear-free seal eliminates most fit issues.

Does mouth breathing cause CPAP leaks?

Yes — breathing through your mouth with a nasal mask or nasal pillow lets pressurized air escape through your open mouth, showing as a large leak. A chinstrap, full-face mask, or switching therapy approach can help.

Are CPAP large leaks vs unintentional leaks different?

Yes — all CPAP masks have intentional vent holes (exhalation ports) that the machine accounts for. 'Large leak' or 'unintentional leak' refers to air escaping outside those vents, usually around the mask seal.

Can CPAP leaks affect my AHI score?

Yes — significant leaks reduce the air pressure reaching your airway, which can cause your AHI to rise (more apnea events) even while appearing to use CPAP regularly. Fixing leaks often improves AHI dramatically.

How does a headgear-free CPAP interface reduce leaks?

Traditional masks rely on strap tension to create a seal — over- or under-tightening breaks the seal. BleepSleep's Eclipse uses a magnetic nasal seal that conforms without straps, removing the #1 cause of positional leaks.

Should I wake up to fix a CPAP leak during the night?

If your machine alerts you or you notice air blowing on your face, a quick repositioning usually fixes it. If leaks happen consistently every night, it is a mask fit or style issue — address it during the day rather than disrupting your sleep repeatedly.

Best Alternative to the ResMed AirFit P10, No Headgear Required

Why Headgear Is the Root Cause of Most P10 Complaints Does removing headgear mean the mask will leak more than my P10? No. Independent testing shows the opposite for Bleep interfaces, since the adhesive seal does not depend on tension that can loosen overnight the way headgear does. Movement during the night is far less likely to break the seal on a no headgear interface. Is a no headgear CPAP interface covered by insurance the same way the AirFit P10 is? Yes. Both the Eclipse and DreamPort are billed under standard nasal mask and nasal pillow HCPCS codes and are covered by Medicare and most private insurance plans, the same general category as the P10. How do I know if I should choose the Eclipse or the DreamPort as my no headgear option? Nostril shape is the main factor. The Eclipse tends to suit nostrils that sit more level to the ground, while the DreamPort tends to suit more angular noses with a steeper V shaped angle. Reach out to the Bleep team for fitting guidance if you are unsure. Is it hard to learn how to apply an adhesive CPAP interface after years of using headgear? Most users adjust within the first week. The main steps are cleaning the skin with a mild astringent, allowing it to dry fully, and applying the adhesive interface with the included instructions or video guide. The Bottom Line If the elastic headgear on your ResMed AirFit P10 has been the actual source of your leaks, strap marks, or discomfort, switching to a different headgear based mask will likely bring the same problems back eventually. A true no headgear interface removes the mechanical cause entirely. Both the Bleep Eclipse and Bleep DreamPort are built specifically for CPAP users who want to be done with straps for good. Talk with your sleep physician about whether a headgear free interface matches your prescribed pressure, then explore the current Eclipse and DreamPort options and check your insurance eligibility directly through Bleep.

DreamPorts vs ResMed AirFit P30i: Head to Head Comparison for Active Sleepers

Active sleepers put CPAP masks through a workout that most designs were never built for. Rolling from your back to your side, tossing an arm over your head, or sleeping stomach down for part of the night all put mechanical stress on a mask in ways a stationary back sleeper never experiences. If you have tried a standard nasal pillow mask and woken up with the hose wrapped around your neck or the seal broken from a middle of the night roll, you already understand the problem. The ResMed AirFit P30i was built specifically to address this with a top of head hose connection. The Bleep DreamPort takes a different route entirely, removing headgear and hose bulk from the equation altogether. Both are genuinely good options for restless sleepers, but they solve the same problem in very different ways, and knowing the difference matters before you commit to a 90 day supply. What the DreamPort Sleep Solution Is and How It Works The DreamPort is a mask less, headgear free CPAP interface that fits directly at the nostril opening using medical grade adhesive strips, without inserting into the nostrils the way nasal pillows do. There is no headgear, no elastic strap, and no cushion body resting against your face. The interface connects to a short, flexible tube that runs to your CPAP machine, and Bleep includes a 10 inch connecting tube compatible with standard CPAP machines. According to independent SleepHQ testing, Bleep interfaces including the DreamPort ranked number one overall for leak stability among tested CPAP masks, with a recorded leak rate of 1.68 liters per minute. The DreamPort is FDA cleared under 510(k) number K172335 and is covered by Medicare and most private insurance plans. What the ResMed AirFit P30i Is and How It Works The AirFit P30i is a nasal pillow mask built around a top of head tubing connection instead of the traditional side or front hose routing. The hollow frame headgear connects the hose over the crown of the head rather than out to the side, which reduces the chance of the tube catching on a pillow or getting pulled sideways when you turn. The mask uses a soft, flexible SpringFit frame designed to stretch and move with you, along with dual wall nasal pillow cushions that slide into the nostrils for a secure seal. ResMed markets the P30i as one of its quieter masks, at roughly 21 decibels, using QuietAir vent technology to disperse exhaled air away from your face and your partner. Hose Routing: Top of Head vs No Hose Bulk at All This is the core design philosophy difference between the two masks. The P30i solves hose interference by routing the tube up and over the top of your head with a 360 degree swivel connector, which does genuinely reduce tangling and pulling for many active sleepers compared to a side mounted hose. The DreamPort solves the same problem differently, by using a much shorter, lighter tube and removing the headgear that the hose would otherwise be anchored to. Without a strap system holding the mask in place, there is simply less hardware on your head for the tube to catch or drag against in the first place. Both approaches reduce tube interference, but the DreamPort removes an entire layer of hardware that the P30i still relies on. Headgear Stability During Movement The P30i uses hollow frame headgear with a SpringFit design intended to flex and adapt as you move, which is a real improvement over older, more rigid headgear designs. Still, it is headgear, and headgear depends on tension. If you are a heavy mover, especially someone who changes position multiple times a night, tension based systems eventually loosen or shift. The DreamPort removes headgear entirely. Bleep states the interface fits the exact shape of your nose using adhesive rather than tension, so a roll from your back to your side does not pull a strap out of alignment the way it can with a headgear based system. Bleep specifically lists side and stomach sleepers, along with patients who have abandoned CPAP due to discomfort, as ideal candidates for the DreamPort. Leak Performance for Restless Sleepers Leaks are especially common among active sleepers because movement is the number one cause of seal displacement in headgear based masks. The P30i dual wall pillow cushions are designed to hold a seal more reliably through movement than older single wall designs, and the top of head hose routing reduces one common cause of displacement, tube pull. The DreamPort approaches the same problem from the seal itself rather than the hose. Because the adhesive interface holds its position independent of tension or hose angle, the SleepHQ leak rate data referenced above reflects a highly stable seal that does not depend on the mask staying centered under strap pressure. For sleepers who move constantly through the night, this is a meaningful practical difference, not just a specification on paper. Comfort and Facial Contact The P30i nasal pillow cushions sit inside the nostril opening, which some active sleepers find can shift slightly with heavy movement, though the dual wall design is meant to minimize this. The headgear, while soft, still makes contact with the scalp and can leave light pressure marks after a full night, particularly for side sleepers whose head rests directly on the strap. The DreamPort sits at the nostril opening rather than inserting into it, and Bleep notes it does not enter the nostrils the way traditional nasal pillows do. Combined with the absence of headgear, most users report no pressure marks, no strap indentations, and no hair breakage from elastic bands, since there is no elastic in contact with the scalp at all. Which Interface Handles Active Sleep Better Both masks were designed with movement in mind, but they take opposite approaches. The P30i keeps headgear but relocates the hose to reduce interference. The DreamPort removes headgear and hose bulk from the equation almost entirely. If you move moderately at night and mainly need a hose that will not tangle, the AirFit P30i top of head design is a genuine solution and a well engineered mask. If you are a heavy mover, a committed side or stomach sleeper, or someone who has tried strap based masks repeatedly and still wakes up with a broken seal, the DreamPort Sleep Solution removes the mechanical cause of the problem rather than working around it. You can review current DreamPort kits and accessories directly through Bleep, and compare fit guidance against the Eclipse if you are unsure which nostril angle suits you better. Cost and Insurance Coverage Both interfaces are typically covered under Medicare and most private insurance plans when prescribed for a documented obstructive sleep apnea diagnosis. The AirFit P30i follows a standard nasal pillow replacement schedule for cushions and headgear set by Medicare. The DreamPort interface is billed under HCPCS codes A7034 for nasal mask and A7033 for nasal pillow cushions, with the reusable DreamWay frame typically replaced every 90 days and the adhesive DreamPort strips used nightly. You can check your specific insurance coverage before switching interfaces. Frequently Asked Questions Is the DreamPort really better for active sleepers than a top of head hose design? It depends on what is causing your problem. If tube interference is your main issue, the top of head routing on the P30i genuinely helps. If the headgear itself is shifting or loosening from movement, the DreamPort removes that variable entirely by using an adhesive seal instead of tension. Can I use the DreamPort if I sleep on my stomach most of the night? Yes. Bleep specifically designed the DreamPort for stomach and side sleepers, since there is no headgear body or strap system pressing into a pillow when you turn face down. Does the DreamPort fit my existing CPAP machine? Yes. The DreamPort includes a 10 inch connecting tube compatible with standard CPAP machines. If you use a ResMed mini or travel device, confirm connector compatibility with your supplier before ordering. Will I still feel the hose pulling with the DreamPort the way I did with a side mounted tube? Most users report significantly less pulling sensation, since the tube is shorter and there is no headgear anchoring point for it to drag against. Some active sleepers still prefer a tube management clip for extra security. Is the AirFit P30i a bad choice for restless sleepers? No. It is a well engineered mask built specifically to reduce hose tangling through its top of head connection and flexible SpringFit frame. It remains a solid option for sleepers whose main issue is tube interference rather than headgear stability. How do I know if my nostril shape works better with the DreamPort or the Eclipse? Bleep notes the DreamPort tends to suit more angular noses with a pronounced V shaped nostril angle, while the Eclipse suits nostrils that sit more level to the ground. If you are unsure, reach out to the Bleep team for fitting guidance before ordering. The Bottom Line Active sleepers do not have to choose between comfort and a stable seal. If tube tangling has been your main complaint, the ResMed AirFit P30i top of head design solves that specific problem well. If your real issue has been a headgear system that will not stay put through a full night of movement, the Bleep DreamPort removes the headgear entirely rather than trying to reinforce it. Talk with your sleep physician about which interface matches your prescribed pressure, and explore the current DreamPort lineup to check insurance eligibility before you switch.

Best CPAP Mask for Side Sleepers Who Breathe Through Their Mouth in 2026

If you sleep on your side and breathe through your mouth, almost every standard CPAP mask recommendation will send you toward a full face mask. The logic seems straightforward: you breathe through your mouth, so the mask needs to cover your mouth. But if you have tried a full face mask as a side sleeper, you already know the problem. Full face masks are bulky. They press into your pillow when you roll over, breaking the seal. The headgear shifts when you change position, pulling the cushion off-center. The larger contact area means more places for leaks to develop. And for a side sleeper who naturally moves during the night, the result is a cycle of waking, readjusting, and trying to fall back asleep that defeats the purpose of therapy entirely. This guide breaks down what actually works for side sleepers who mouth breathe. It covers why the typical full face mask recommendation often falls short for this combination, what the real alternatives look like, and how to evaluate which approach fits your specific situation. 1. Why the Side Sleeper Plus Mouth Breather Combination Is Uniquely Difficult Side sleeping and mouth breathing create two separate problems that each require different solutions. The trouble is that the conventional solution for one makes the other worse. Mouth breathing during CPAP therapy means pressurized air escapes through your open mouth rather than staying in your airway. This drops your effective therapy pressure, causes dry mouth and sore throat, and shows up as elevated leak rates on your CPAP compliance data. The standard fix is a full face mask that covers both nose and mouth. Side sleeping creates a different problem: anything with significant contact area on the face gets pushed out of position when your cheek hits the pillow. The cushion edge bears force it was not designed to handle for hours at a stretch. The headgear, running along the side of your face, gets caught between your head and the pillow. Full face masks have more contact area than any other mask type, which means they get displaced more aggressively by pillow contact than smaller masks do. According to the American Academy of Sleep Medicine, mask leaks and discomfort are among the primary drivers of CPAP non-adherence. Side sleepers report disproportionately higher rates of mask displacement and leak events compared to back sleepers using the same equipment. Adding mouth breathing to the equation compounds both problems. 2. The Three Approaches to This Problem Approach 1: Full face mask with top-of-head tubing The most common recommendation for mouth-breathing side sleepers is a compact full face mask with a top-of-head tubing attachment. Models like the ResMed AirFit F30 and Philips DreamWear Full Face route the air hose from the top of the head rather than straight out from the front of the mask, which reduces the drag on the mask when you roll over. This approach works reasonably well for some patients. The top tubing reduces one source of displacement. But the mask cushion and frame still have significant contact area, and the headgear still runs along the sides of the head. For active side sleepers or anyone with a tendency toward claustrophobia, the bulk of a full face mask remains a real obstacle to consistent use. Approach 2: Nasal mask or nasal pillow with a mouth breathing solution A lower-profile nasal interface paired with a dedicated mouth breathing solution keeps the mask footprint small while addressing the open-mouth problem separately. This is a less commonly discussed approach, but it often works better for side sleepers because it removes the pillow-contact problem by reducing the mask to a minimal nasal footprint. The mouth breathing component can be addressed through SomnoSeal, a nasal breathing trainer that sits in front of your teeth and keeps your mouth gently closed during sleep. Unlike a chin strap, SomnoSeal works from inside the mouth without adding external pressure to the jaw or face. This combination, a low-profile nasal interface plus SomnoSeal, lets side sleepers stay in a comfortable, low-contact mask while keeping the mouth-leak problem solved. SomnoSeal is available at bleepsleep.com alongside BleepSleep nasal interfaces, and pairing it with a low-profile design is one of the more practical paths for side sleepers who mouth breathe. Approach 3: Headgear-free nasal interface Headgear-free interfaces represent the most significant departure from conventional CPAP mask design. Without headgear, there are no straps to shift when you roll over, no cushion body to press into a pillow, and no frame running across your face. The interface sits at the nostrils and holds there through adhesive or magnetic-seal technology rather than strap tension. BleepSleep's Eclipse CPAP Solution and DreamPort Sleep Solution are both headgear-free nasal interfaces. The Eclipse uses MagSeal technology with disposable Halos adhesive interfaces for a secure seal with no straps. The DreamPort fits at the nostrils with no inserts and no headgear of any kind. For side sleepers, removing headgear from the picture eliminates the primary mechanical cause of nightly displacement. Paired with SomnoSeal to manage mouth breathing, a headgear-free nasal interface gives side sleepers both a low-profile design that stays in place through position changes and a solution for the open-mouth problem, without needing a full face mask. 3. How to Decide Which Approach Fits You Start with your compliance data Before switching mask types, pull your CPAP compliance report and look at what your leak data actually shows. If your current mask produces high leak rates consistently on side-sleeping nights, that confirms the displacement problem. If the leaks are high but not tied to position, mouth breathing may be the primary issue rather than mask fit. Your sleep specialist can help you interpret the data correctly, which avoids switching equipment in the wrong direction. Identify your primary complaint Patients who mainly struggle with mask displacement during side sleeping but tolerate their mask reasonably well otherwise are good candidates for a headgear-free interface. The goal is reducing the bulk that gets caught on the pillow, not necessarily changing the therapy route. Patients whose main issue is dry mouth, raw throat, or high leak rates that persist even when they stay in one position are dealing primarily with mouth breathing. A full face mask solves that directly but adds mask bulk. A nasal interface plus SomnoSeal solves it while keeping the footprint small. Patients dealing with both issues simultaneously, displacement from side sleeping and mouth-leak driven dry mouth, benefit most from the combination of a headgear-free nasal interface and SomnoSeal. Consider your history with claustrophobia If you have struggled with claustrophobia from any mask before, a full face mask is the least likely solution to work long-term. Claustrophobia from CPAP typically comes from the combination of full-face coverage and tight headgear, which is exactly what a full face mask provides. Low-profile and headgear-free designs remove both elements. For claustrophobic side sleepers who also mouth breathe, a headgear-free nasal interface paired with SomnoSeal is usually the most practical path to sustained compliance. 4. What to Ask Your Sleep Specialist Before making any change, bring your compliance and leak data to your next appointment rather than describing the problem verbally. Specific numbers give your provider a clearer picture than a general description of the issue. Useful questions to raise with your sleep specialist include: whether your leak data suggests primarily mouth leaks or seal displacement, whether a low-profile nasal interface at your prescribed pressure would be sufficient for your AHI, whether SomnoSeal is an appropriate option for your specific situation, and whether a headgear-free interface is covered under your current insurance plan. Your provider can also request a prescription trial of a different interface type if your current setup has not been working. Many insurance plans allow for mask trials when there is documented evidence of compliance difficulty, so it is worth asking. 5. The Role of CPAP Pillows and Sleeping Position CPAP pillows with cutouts for the mask and tubing can reduce displacement for some side sleepers, particularly those using compact nasal masks. They work by removing the solid pillow surface from the area where the mask makes contact, so the mask does not get pushed as it presses into the foam. A CPAP pillow works best as a complement to a low-profile interface rather than a substitute for one. A headgear-free interface has so little bulk at the face that the pillow cutout is less critical. But for patients using a compact full face mask or nasal mask with some frame extension, a CPAP pillow can meaningfully reduce nightly displacement. Frequently Asked Questions What is the best CPAP mask for side sleepers who breathe through their mouth? There is no single best option because the right mask depends on your primary complaint. If mask displacement is the main issue, a headgear-free nasal interface like BleepSleep's Eclipse or DreamPort removes the bulk that gets caught on the pillow. If mouth breathing is the primary driver of leaks and dry mouth, a nasal interface paired with SomnoSeal addresses both without requiring a full face mask. Many side sleepers who mouth breathe benefit from combining both approaches. Do I have to use a full face mask if I breathe through my mouth during sleep? No. A nasal interface paired with a mouth closure solution like SomnoSeal can address mouth breathing without requiring a full face mask. Whether this combination is appropriate for your therapy depends on your prescribed pressure and AHI, which your sleep specialist can confirm. Why does my CPAP mask keep leaking when I sleep on my side? Side sleeping puts direct pressure on the mask cushion and headgear from the pillow, pushing the interface out of position and breaking the seal. Masks with larger contact areas and more headgear are more susceptible to this. Switching to a low-profile or headgear-free interface removes most of the bulk that gets displaced, which typically reduces or eliminates side-sleeping leaks. Can I use a nasal pillow mask if I breathe through my mouth? Nasal pillow masks deliver therapy through the nostrils and do not cover the mouth. If you use one and breathe through your mouth during sleep, the pressurized air escapes through the open mouth rather than staying in your airway. Adding SomnoSeal to a nasal pillow mask setup keeps the mouth closed during sleep, which allows you to benefit from the lower profile of the nasal design while keeping the mouth-leak problem in check. Is a headgear-free CPAP mask as effective as a traditional mask for treating sleep apnea? Yes, when correctly fitted and used at the prescribed pressure. A headgear-free interface delivers the same continuous positive airway pressure as a traditional mask. The difference is how the seal is maintained. Your sleep specialist can confirm that a specific headgear-free design matches your prescribed pressure and AHI before you switch. How do I know if my CPAP problems are from side sleeping or from mouth breathing? Check your CPAP compliance data and compare high-leak nights to how you remember sleeping. Dry mouth and sore throat in the morning are strong indicators of mouth breathing. Mask-shaped marks on your face and mask that is visibly shifted when you wake point more toward side-sleeping displacement. Many patients have both issues, and your sleep specialist can help you interpret your compliance data to identify which is primary. The Bottom Line Being a side sleeper who breathes through your mouth does not mean you are stuck with a bulky full face mask. The combination of a low-profile or headgear-free nasal interface with a mouth closure solution like SomnoSeal gives you effective therapy in a setup that actually works with how you sleep, rather than fighting it. BleepSleep's Eclipse CPAP Solution, DreamPort Sleep Solution, and SomnoSeal are all designed for patients who have not found what they need in conventional mask designs.

On their own, nasal-only interfaces are not suitable for consistent mouth breathers without an oral seal solution.Does sleeping on your side make it harder to keep a full-face mask sealed?Yes. Full-face masks can gap when pressed against a pillow, allowing air to escape around the seal. Low-profile nasal cushions or minimal-contact designs are less susceptible to pillow displacement.How can I tell if I am a mouth breather during CPAP therapy?Signs include waking with extreme dry mouth, throat soreness, high leak rate readings on your CPAP machine data, or your bed partner observing your mouth open during sleep.
