Present notes:

Hey everyone, Chris Kresser right here. Welcome to a different episode of Revolution Well being Radio. At this time we’re going to speak about one thing that’s been throughout social media recently– mouth taping. For those who spent any time on TikTok or Instagram previously couple of years, you’ve most likely seen influencers raving about how taping their mouth shut at night time has remodeled their sleep, cured their loud night breathing, improved their jaw construction, and perhaps even made them look youthful. A few of these movies have lots of of thousands and thousands of views, and the claims are fairly dramatic.

Now I’ve a considerably distinctive perspective on this as a result of I take advantage of mouth tape myself. However earlier than you suppose I’m right here to inform you that mouth taping is the reply to all of your sleep issues, I wish to share what the science says. A significant systematic assessment revealed in Could 2025 examined all accessible analysis on mouth taping, and the findings are rather more nuanced than what you’re seeing on social media. The reality is, for some folks in particular circumstances, mouth taping might be useful. For others, it may make issues worse and even be harmful. This issues as a result of we’re seeing a sample the place social media traits get method forward of the science, and other people find yourself making an attempt interventions which may not be proper for them with out understanding the context or dangers. I’ve talked about this earlier than with different well being traits, and mouth taping is an ideal instance.  There’s a kernel of fact right here. Nasal respiratory throughout sleep is mostly higher than mouth respiratory, and there are some conditions the place mouth taping can help that. However as is usually the case, the satan is within the particulars, and people particulars matter so much relating to your security and whether or not this intervention will truly show you how to.

By the top of this episode, you’ll perceive when mouth taping is likely to be useful, when it could possibly be dangerous, why particular person variation issues a lot, and what you must contemplate earlier than making an attempt it your self. Let’s dive in.

Let’s begin with the essential science, as a result of understanding why nasal respiratory issues helps clarify why persons are interested by mouth taping within the first place. Your nostril isn’t only a backup airway for when your mouth is busy. It’s designed to be your major respiratory route, particularly throughout sleep. Whenever you breathe by means of your nostril, a number of vital issues occur. The nasal passages filter the air, eradicating mud, allergens, and pathogens. They heat and humidify the air earlier than it reaches your lungs. And crucially, nasal respiratory produces nitric oxide, which helps dilate blood vessels and enhance oxygen supply all through your physique. A long time of analysis have proven that nasal respiratory throughout sleep is related to decrease higher airway resistance than mouth respiratory. A research revealed within the European Respiratory Journal in 2003 instantly measured this in wholesome folks throughout sleep. They discovered that higher airway resistance was considerably decrease throughout nasal respiratory than throughout oral respiratory. Not solely that, however when folks breathed by means of their mouths throughout sleep, that they had a marked enhance in obstructive occasions. So the essential physiology checks out. Nasal respiratory is preferable to mouth respiratory throughout sleep.

Whenever you breathe by means of your mouth at night time, particularly chronically, it could possibly result in a cascade of issues. Your mouth and throat dry out, which is uncomfortable and creates an surroundings the place micro organism thrive. This contributes to dangerous breath, and over time, it could possibly enhance your danger of cavities and gum illness. Mouth respiratory can even make loud night breathing worse as a result of the smooth tissues in your throat loosen up extra when your mouth is open, which partially blocks your airway. In additional severe instances, this will contribute to or worsen obstructive sleep apnea, the place your respiratory repeatedly stops and begins all through the night time.

So given all of this, you possibly can see why the thought of utilizing tape to maintain your mouth closed at night time appears logical. If nasal respiratory is best, and mouth taping ensures you breathe by means of your nostril, then mouth taping ought to enhance your sleep, proper? Nicely, that’s the place issues get extra difficult. The systematic assessment I discussed earlier, revealed in PLOS One in Could 2025, examined all scientific literature on mouth taping from 1999 to 2024. The researchers used rigorous PRISMA tips, that are the gold customary for systematic evaluations. They screened 120 articles and chosen 10 research that met their inclusion standards. These 10 research included a complete of 213 sufferers, and used numerous strategies to maintain the mouth closed, together with adhesive tape, mouth seals, and chin straps. Right here’s what they discovered. The proof for well being advantages for mouth taping is weak and inconsistent. Extra importantly, they recognized some severe security considerations. First, all 10 research have been rated as low high quality, which implies we must be cautious about drawing sturdy conclusions. The pattern sizes have been small, the research designs different extensively, and there have been many limitations in how the analysis was carried out. Second, and that is important, the assessment discovered that mouth taping can truly worsen sleep-disordered respiratory by limiting airflow. There’s even a danger of suffocation in case you have nasal obstruction and your mouth is taped shut. Take into consideration that for a second. When you have congestion from allergy symptoms, a chilly, or a deviated septum, and also you tape your mouth closed, you’ve simply blocked your major airway and not using a backup. That’s not a theoretical danger. That’s an actual hazard. Third, the researchers famous one thing known as “mouth puffing.” That is fascinating and regarding. Some sufferers with taped mouths developed a compensatory conduct the place their cheeks would inflate and deflate, nearly like they’re making an attempt to breathe across the obstruction. And right here’s the kicker: this mouth puffing truly worsened their Apnea-Hypopnea Index, which is the primary measure of sleep apnea severity. So in these instances, taping the mouth didn’t simply fail to assist, it made issues worse.

Now you is likely to be considering, “Wait, Chris, you simply mentioned you utilize mouth tape your self. How do you rating that with all these security considerations?” Nicely, that’s a terrific query, and it will get to the guts of why context issues a lot. Let me inform you my story, as a result of it illustrates the distinction between indiscriminate mouth taping and its use as a part of a complete strategy. When my household and I moved to Park Metropolis, Utah in 2019, I developed gentle sleep apnea. I didn’t have it after we lived within the Bay Space at sea stage, however at 6500 toes, the decrease oxygen ranges have been sufficient to set off gentle apnea. It wasn’t extreme sufficient to warrant a CPAP machine, and albeit, I didn’t wish to go in that path if I may keep away from it. However I knew I wanted to handle it, as a result of I used to be conscious of the analysis linking sleep apnea with many alternative well being situations. I already suspected that my jaw anatomy was contributing to airway points. Again in eighth grade, I had 4 grownup tooth eliminated by a dentist who didn’t perceive the long-term penalties of that intervention. Eradicating these tooth triggered my jaw to slender, and it compromised my airway. So I discovered a dental orthopedist in Park Metropolis who focuses on sleep apnea and airway points. He created a customized system for me to put on at night time, much like a mandibular development system, that helps open my airways and facilitates clear nasal respiratory. As soon as I began utilizing that system, I added mouth taping, and I’ve had superb outcomes. However right here’s the essential level. The system opens my airway and nasal passages, which makes mouth taping doable and secure for me. With out addressing the underlying anatomical concern first, I don’t suppose mouth taping would have helped a lot. It may need even triggered hurt by forcing me to breathe by means of {a partially} obstructed airway. The mouth tape isn’t fixing something. It’s supporting the intervention that really addresses the basis trigger, which is enhancing my airway patency.

Mouth taping is trending all over the place on social media—however does it truly enhance sleep? On this episode, Chris breaks down the science behind mouth taping, when it would assist, when it may make sleep apnea worse, and why airway anatomy issues. #ChrisKresser

This brings us to a extremely vital research revealed in JAMA Otolaryngology in 2024 that helps clarify why mouth taping works for some folks however not others. Researchers at Harvard studied 54 folks with obstructive sleep apnea and manually closed their mouths throughout sleep to see how this affected their respiratory. They discovered that about 60 % of contributors breathed extra simply with their mouths closed. However for a big minority, that different 40 %, closing the mouth truly made respiratory worse. The important thing issue was airway anatomy, particularly the taste bud. When you have a considerable blockage in that space, you’re extra more likely to mouth breathe as a result of that’s your primary pathway for air. For these folks, closing the mouth blocks their major airway, which reduces complete airflow. That’s harmful. Alternatively, in the event you don’t have vital blockage on the taste bud, closing your mouth can truly open the airway extra totally and enhance respiratory. The lead researcher, Dr. Philip Huyett, put it properly. He mentioned that individuals who depend on mouth respiratory due to sleep apnea might discover that tape makes respiratory worse. You’re avoiding nasal respiratory as a result of you could have sleep apnea, and in the event you shut your mouth, there’s much less of an airway to breathe by means of. This particular person variation is why a one-size-fits-all suggestion doesn’t work right here.

There’s one other context the place mouth taping has proven promise: when utilized in mixture with a mandibular development system, as in my case. A 2022 research within the Annals of the American Thoracic Society discovered that combining mouth taping with a mandibular development system was considerably simpler than utilizing the system alone. The researchers theorized that the mandibular development system can enhance mouth respiratory, which reduces its effectiveness. By including mouth tape to maintain the mouth closed, they noticed higher outcomes. In that research, 76 % of contributors achieved an Apnea-Hypopnea Index of lower than 10 occasions per hour with the mixture of the system and mouth tape, in comparison with solely 43 % with the system alone. The median AHI dropped from 10.5 to five.6 occasions per hour. That’s a clinically significant distinction. However once more, this was in a selected context– individuals who have been already utilizing a mandibular development system and had clear nasal passages. It wasn’t simply random folks taping their mouths primarily based on what they noticed on TikTok.

So what does all of this imply for you? For those who’re contemplating mouth taping, right here’s what it is advisable know. First, don’t use mouth taping as an alternative choice to correct analysis and therapy of sleep apnea. For those who’re loud night breathing loudly, waking up gasping for air, or your accomplice notices that you just cease respiratory throughout sleep, these are indicators of obstructive sleep apnea, and it is advisable see a physician or a dentist who specializes on this. Mouth taping gained’t remedy sleep apnea by itself. In actual fact, in case you have reasonable to extreme apnea, mouth taping could possibly be harmful, since you may need episodes the place you’re not respiratory adequately and your physique must wake you as much as breathe. In case your mouth is taped shut and you’ve got nasal obstruction, that’s an issue.

Second, earlier than making an attempt mouth taping, be certain your nasal passages are clear. When you have continual nasal congestion, allergy symptoms, a deviated septum, or nasal polyps, it is advisable handle these points first. Forcing your self to breathe by means of an obstructed nostril by taping your mouth shut will increase the work of respiratory and may result in fragmented sleep, or worse. See a useful drugs clinician about treating your nasal congestion. That may imply dietary modifications, addressing intestine well being, nasal sprays, or, in some instances, seeing a surgeon to appropriate structural points.

Third, in the event you do attempt mouth taping, do it fastidiously and take note of how you are feeling. Begin by making an attempt it for brief intervals when you’re awake to get used to the feeling. Use tape designed for delicate pores and skin that gained’t irritate your lips. Don’t use duct tape or different industrial tape. There are merchandise particularly made for mouth taping that use a mild adhesive. And in the event you get up feeling such as you’re not getting sufficient air, otherwise you’re extra drained after sleeping with mouth tape than with out it, cease doing it. Your physique’s telling you one thing.

Fourth, contemplate working with a dentist who focuses on sleep drugs and understands airway anatomy. This was essential for me. These specialists can assess whether or not you could have anatomical points which are contributing to mouth respiratory or sleep-disordered respiratory. They will advocate interventions like mandibular development gadgets, palate enlargement, or myofunctional remedy. Addressing the basis trigger makes an enormous distinction, and it would make mouth taping simpler and safer in the event you select to attempt it. I wish to emphasize one thing I’ve typically mentioned earlier than: there’s no one-size-fits-all strategy to well being interventions. What works for one particular person might not work for an additional, or might even be dangerous. We see this with food regimen, with train, and undoubtedly with one thing like mouth taping. Your airway anatomy, your nasal patency, whether or not you could have sleep apnea, the severity of your sleep apnea, and what underlying components are contributing to your sleep points all matter. These particular person components decide whether or not mouth taping will show you how to.

Social media is usually a nice supply of knowledge and concepts, and I’m glad that persons are exploring other ways to optimize their well being. However we’ve seen over and over that viral well being traits typically get forward of the science, and vital context will get misplaced within the pursuit of views and engagement. Mouth taping is an ideal instance. The fundamental concept, that nasal respiratory is best than mouth respiratory, is sound. However the leap from that precept to “everybody ought to tape their mouth at night time” shouldn’t be supported by the proof. If there’s one factor I need you to remove from this episode, it’s that context is the whole lot. Mouth taping is likely to be useful for folks with gentle sleep apnea who’ve clear nasal passages and are utilizing it together with different interventions that handle underlying anatomical points. However for folks with reasonable to extreme sleep apnea, nasal obstruction, or sure kinds of airway collapse, it could possibly be ineffective and even harmful. And for most individuals, we simply don’t have sturdy proof but on whether or not it helps.

The perfect strategy is to begin with a correct analysis. For those who’re involved about your sleep high quality, in the event you’re loud night breathing, in the event you’re waking up drained, regardless of sleeping for what must be sufficient hours, see a physician or a dentist who specializes on this. Get a sleep research if applicable. Work with individuals who perceive the mechanics of respiratory and sleep. Tackle any underlying points like nasal congestion or anatomical issues. Then, if taping is smart in your particular state of affairs, you possibly can attempt it as a part of a complete strategy, not as a standalone magic bullet.
