B Evidence
Time to Benefit 1-2 weeks
Cost $5-10/month

Bottom Line

Mouth taping is a low-cost, low-risk intervention with plausible benefits backed by solid mechanistic evidence. Nasal breathing is clearly superior to mouth breathing - the question is whether taping is necessary or if habit change alone is sufficient.

Worth trying if you wake with dry mouth, snore, or suspect you mouth breathe during sleep. Start with gentle tape during the day to ensure comfort, then use nightly. Stop if you have nasal congestion or feel anxious.

Science

Mechanisms:

  • Nasal breathing filters, warms, and humidifies incoming air
  • Nose produces nitric oxide - a vasodilator that improves oxygen uptake
  • Nasal breathing promotes diaphragmatic breathing patterns
  • Nasal resistance creates slight back-pressure that helps maintain airway patency
  • Prevents dry mouth, protecting oral microbiome and dental health

Key concepts:

  • Mouth breathing during sleep is associated with snoring, poor sleep quality, and dry mouth
  • Many people unconsciously mouth breathe at night even if they nasal breathe during the day
  • Nitric oxide produced in sinuses improves oxygen transfer in lungs by 10-15%
  • Chronic mouth breathing can lead to facial structure changes, dental problems, and sleep disruption

Evidence base:

  • Nasal vs mouth breathing benefits: well-established in literature
  • Nitric oxide production in nasal passages: proven mechanism
  • Mouth taping specifically: limited RCTs but growing clinical interest
  • Strong anecdotal reports from sleep and breathing communities
  • Increasing adoption by dentists and sleep specialists

Limitations:

  • Few controlled trials specifically on mouth taping
  • Not appropriate for those with nasal obstruction
  • Doesn't address underlying causes (allergies, deviated septum, polyps)
  • May not help if nasal passages are chronically blocked

Practical Protocol

Getting started:

  1. Test during day first - Wear tape for 30-60 minutes while awake to ensure comfort and that you can breathe easily
  2. Ensure nasal patency - Clear sinuses before bed; don't tape if congested
  3. Start simple - Use a small piece of tape vertically over center of lips (not sealing entire mouth)
  4. Use nightly - Consistency matters; benefits typically appear after 1-2 weeks

Tape application:

  • Clean, dry lips before applying
  • Place tape vertically from upper lip to lower lip
  • Some prefer horizontal tape; experiment with what feels secure but comfortable
  • Tape should be removable - you can push it off with tongue if needed

Tape options:

  • Surgical/micropore tape (~$3-5) - Cheapest option, works well, available at any pharmacy
  • 3M Nexcare gentle tape (~$5) - Gentler adhesive for sensitive skin
  • Purpose-made mouth tape (Somnifix, Hostage Tape) (~$15-20) - Designed for sleep, easier removal, better adhesive

Progression:

  • Week 1: Get comfortable with tape, ensure no anxiety
  • Week 2+: Use consistently, track results
  • Ongoing: Make it automatic habit, like brushing teeth

Risks & Side Effects

Contraindications - do NOT use if:

  • Nasal obstruction, deviated septum, or nasal polyps
  • Active cold, allergies, or sinus congestion
  • Sleep apnea (without explicit doctor approval)
  • Anxiety or panic around restricted breathing
  • BMI > 35 (higher risk of sleep-disordered breathing)
  • Alcohol consumption (impairs arousal response)

Stop immediately if:

  • You feel anxious or panicked
  • You can't breathe comfortably through nose
  • You wake up gasping or removing tape unconsciously
  • Any skin irritation from adhesive

Risk mitigation:

  • Tape can be easily removed or pushed off with tongue
  • Start with day practice to build confidence
  • Use gentler tape if skin irritation occurs
  • Never use strong adhesive tape (duct tape, packing tape)

Safety note:

Mouth taping is NOT a treatment for sleep apnea. If you suspect sleep apnea (loud snoring, gasping, excessive daytime sleepiness), get a sleep study first. Some practitioners use mouth taping alongside CPAP, but only with medical supervision.

Who It's For

Ideal for:

  • People who wake with dry mouth
  • Snorers (confirmed by partner or app)
  • Those who know they mouth breathe during sleep
  • People interested in optimizing sleep quality
  • Nasal breathers during day who suspect mouth breathing at night

Particularly beneficial for:

  • Chronic dry mouth sufferers
  • People with morning sore throat
  • Those whose partners complain about snoring
  • Anyone who's tried everything else for sleep quality

Should NOT use:

  • Anyone with nasal obstruction or congestion
  • People with sleep apnea (without doctor supervision)
  • Those with anxiety about restricted breathing
  • After alcohol consumption
  • People with BMI > 35 (higher risk of sleep-disordered breathing)

How to Track Results

Key metrics to monitor:

  • Morning mouth/throat dryness (1-10 scale)
  • Subjective sleep quality (1-10 scale)
  • Snoring (ask partner or use sleep tracking app)
  • Morning energy levels
  • Time to fall asleep
  • Night wakings

Tracking methods:

  • Simple sleep journal
  • Sleep tracking apps (Sleep Cycle, AutoSleep)
  • Smart watch/ring sleep data
  • Snoring apps (SnoreLab)

Signs it's working:

  • Wake with moist mouth instead of dry
  • Partner reports less snoring
  • Feel more rested in morning
  • Fewer night wakings
  • Tape still in place on waking (not pushed off)

Timeline:

  • Days 1-3: Adjustment period, may feel odd
  • Week 1-2: Should notice dryness improvement
  • Week 2-4: Sleep quality improvements if they're going to happen
  • If no benefit after 4 weeks of consistent use, may not be your issue

Top Products

Budget option:

Gentle adhesive:

Purpose-made:

  • Somnifix (~$20/28 strips) - Has breathing vent, designed for sleep
  • Hostage Tape (~$20/30 strips) - Popular option, strong but comfortable adhesive
  • Dryft Sleep Strips (~$15/30 strips) - Gentle, good reviews

Our take: Start with cheap surgical tape. If you stick with it and want convenience, upgrade to purpose-made strips.

Cost Breakdown

Monthly cost: $5-20 depending on tape choice

Breakdown:

  • Surgical tape: ~$5 lasts 2-3 months
  • Purpose-made strips: ~$15-20/month

Cost-per-benefit assessment:

Extremely high ROI if it works for you. Sleep quality improvements worth far more than $5-20/month. One of the cheapest interventions with meaningful potential upside.

ENT surgeon warns against mouth taping without evaluation

Dr. Linda Lee, an ENT surgeon at Massachusetts Eye and Ear, explains that mouth taping is generally not a good idea before a medical evaluation, since many people cannot breathe through their nose due to deviated septums or allergies.

"Any information you could share would be great. Thanks in advance. If you frequent the wellness world on social media, you have probably seen this mouth taping trend. If you avoid wellness TikTok like an unsterilized jade egg, then you probably haven't. But it's people using adhesive tape to force their mouth closed while they're sleeping to promote nose breathing. I absolutely love mouth taping. It has completely changed my life, my sleep, the way that I look. I have such a stuffy nose by nature, deviated septum, all the nose problems, and it forces your nose to kind of clear out. I've never woken up with a clearer nose."

Sleep endoscopy can identify who benefits from mouth taping

Dr. Lee describes drug-induced sleep endoscopy, where doctors put patients to sleep under anesthesia and observe where airway obstruction occurs, allowing them to determine if closing the mouth actually resolves sleep apnea for specific individuals.

"And so in these sleep endoscopies, you can actually see where is the level of obstruction. And there are some people where they close their mouth during that sleep endoscopy and they see that now they don't have sleep apnea. So then now you can actually try to train your body to close your mouth with a chin strap or a mouth tape."

Dangerous conclusion that mouth taping can replace CPAP

Dr. Lee highlights the danger of a 2022 Taiwan study concluding mouth taping could be an alternative to CPAP for mild sleep apnea, noting that people who hate their CPAP will jump at any excuse to abandon it, potentially putting their health at risk.

"Their conclusion, which I think is so dangerous, it says mouth taping could be an alternative treatment in patients with mild sleep apnea before turning to CPAP therapy or surgical intervention. And that kind of stuff is so powerful in potentially a dangerous way because nobody likes their CPAP, right?"

Nasal breathing produces 25% of body's nitric oxide

An estimated 25% of the body's nitric oxide is produced from breathing through the nose. Nitric oxide is critical for vascular health, and low levels are linked to erectile dysfunction, cognitive decline, cardiovascular disease, and sleep disorders.

"So let's jump in. Why is it so bad to breathe through your mouth on a consistent basis? Our nose was primarily designed for breathing and smelling, and our mouth was primarily designed for eating, tasting, and talking. When we use these body parts outside of their intended use, An estimated 25% of our body's nitric oxide is produced from breathing through our nose. This has been taken from a paper published in Wiley Online called Decreased Pulmonary Vascular Resistance During Nasal Breathing. Now, let's do a little background on nitric oxide, a little sidebar, because understanding the importance of nitric oxide and its central role that it plays in our body."

Mouth breathing is the number one cause of cavities

Functional dentist Dr. Mark Burhenne considers mouth breathing to be the number one cause of cavities, even ahead of poor diet. Mouth breathing dries out the mouth, disrupts the oral microbiome, makes the mouth more acidic, and lets bad bacteria take over, leading to cavities and gum disease.

"My friend Dr. Mark Brahanna considers mouth breathing to be the number one cause of cavities, even coming before a poor diet and bad diet."

How to start mouth taping with just a small piece of tape

Dhru Purohit walks through the practical how-to of mouth taping, recommending a quarter-inch piece of inexpensive Medvanced Silicone Tape placed over just the center of the lips to lightly keep them together overnight.

"Right before bed, you're cutting a tiny piece of tape, maybe a quarter of an inch. Now you're placing the mouth tape over the center of your lips, just the center. You're not trying to cover your entire mouth."

Personal experience with mouth taping reducing teeth grinding

Dhru shares that he used to grind his teeth at night, which is one way the body compensates for disordered sleep breathing. After starting mouth taping, he noticed massive improvement in sleep quality and far less jaw tension, and even got his wife on board.

"I'll talk about that more in a future episode. After I started mouth taping, I noticed a massive improvement in my sleep. True story. And way less tension in my jaws. Mouth taping works so well that I even got my wife on board. She has a pretty prominent tongue tie. We haven't gotten the little operation that you can get rid of the tongue tie, but that's definitely on our list in the future. She's a little afraid of doing it right now. So we put her on mouth tape, which I'll talk about in a second."

Mouth Taping Discussion

They actually, so there's a very specific anatomical connection there. But, you know, some people can do mouth taping, and it helps them greatly.

"And if you think about how we're made, it's like the roof of the mouth is the floor of the nose. Okay. So the back of the palate called the palatine bones."

Mouth Taping Discussion

It makes their anesthesia better, makes their recovery better, makes their brain more protected. Give your mouth tape.

"Yeah. Well, what happened to me was I did, so I've done podcasts on mouth taping before. So inevitably, you know, the hostage tape and inhale and respire and all these companies just like sent boxes of nasal strips."

Nasal breathing boosts nitric oxide levels up to 20x vs mouth breathing

A 2019 study in Nitric Oxide Biology and Chemistry showed nasal breathing boosts nitric oxide levels up to 20 times compared to mouth breathing, leading to better circulation and lower blood pressure. Nitric oxide is critical for blood vessel function, brain oxygenation, and immune health.

"A 2019 study in nitric oxide biology and chemistry showed nasal breathing boosts nitric oxide levels up to 20 times compared to mouth breathing. That leads to better circulation and lower blood pressure."

Mouth breathers have 40% higher risk of obstructive sleep apnea

A 2015 study found mouth breathers had a 40% higher likelihood of developing obstructive sleep apnea. Mouth breathing causes the tongue to fall back into the throat, increasing airway resistance, while mouth taping keeps the tongue in its natural resting position against the palate.

"2015 study in American Journal of Respiratory and Critical Care Medicine found that mouth breathers had a 40% higher likelihood of developing obstructive sleep apnea compared to those out there that breathe from the nose."

Mouth taping reduced nighttime awakenings by 25% in study

A 2021 study in the Journal of Clinical Sleep Medicine found that individuals who practiced nasal breathing through mouth taping experienced a 25% reduction in nighttime awakenings and improved daytime energy levels overall.

"Nasal breathing increases oxygen to the brain. As we know, the memory is stronger. The focus is stronger. Your reaction time is stronger. You're reducing dehydration in the mouth. So now you're retaining moisture, preventing dry mouth, which is one of the leading causes of cavities. It optimizes your lung function. We see that in a journal of applied physiology, 2013. Nasal breathing enhances lung capacity. It improves your oxygen exchange by 10 to 20% compared to mouth breathing. You're going to oxygenate your tissues better. You will be healthier if you're nasal breathing by 10 to 20%. Oxygen is essential for your tissue health. Mouth taping is such a simple tool that actually forces the body to rely on nasal breathing when you sleep, right? You're going to seal the lip shut and the tape prevents that unconscious mouth breathing that people do through the night. So it ensures that air is drawn in through the nose. What are the mechanisms? Well, when you're breathing in through the nose, as mentioned, you increase nitric oxide levels. Nitric oxide, when I tell you, is the molecule, you need high nitric oxide levels. And it's produced in the nasal sinuses. And it plays a super crucial role in expanding your blood vessels, improving oxygen delivery. So if you're breathing through your mouth at night, you're theoretically increasing inflammation because you're not elevating those levels of nitric oxide. A 2019 study in nitric oxide biology and chemistry showed nasal breathing boosts nitric oxide levels up to 20 times compared to mouth breathing. That leads to better circulation and lower blood pressure. But it's not only that. Nasal breathing is going to optimize CO2 levels. And this is important because it's going to help oxygen efficiency. When we breathe through the mouth, we expel way too much carbon dioxide. That's going to lead to less oxygen being delivered to the tissues. You know, I'm serious about training. You know, I'm serious about recovery. You know, I'm serious about getting really fit. And my age, 40 years old, we want to be like, I'm 20 year old fit, right? And I learned a lot about quality supplements over my years, especially in school. And let me tell you, there's a supplement called Pure O3 Ultra Pure Fish Oil. It is the best one in the industry. Okay. Best across the board. They only use small fish. They test every single batch against 200 contaminants, 200. And it's essential, especially because a lot of us have really low EPA and DHA. When I was running tests, nutritional tests on people, this was oftentimes something that was really, really low. And it's essential for heart health, brain health, eye health. And guess what? Overall research is also showing that EPA and DHA balance, omega-3s is really, really important for muscle recovery and strength. So if you're active, it's essential. This is a go-to that I put every morning in my little cup, 2000 milligrams of EPA and DHA in their natural form. And it's certified both clean and sustainable. I know I'm getting the best omega threes in the game. Pure is offering you 20% off of this fish oil and actually all of their products. Just go to pure.com slash DRG and use the code DRG at checkout. That is P U O R I.com slash D R G. I am going to talk to you about something crucial for your health. That is your blood vessels, your vascular system. Did you know that your vascular health actually underpins everything in your body? Why? It's all over your body. It's from how vibrant your skin looks, how well your organs and muscles are functioning, right? They need their food and that's the blood. But here's the thing, factors like stress, high sugar diets, right? Just natural aging can actually damage and delicate the inside layer and it needs support. It really does, especially if you're working out, especially if you have a family history of heart disease, especially if you just want to stay healthy. And that's where our friends at Calroy, they come in. They have a product called arterteriosyl HP. Their Arteriosyl HP is the only supplement with something called Monatum RS, and that's a unique seaweed-derived ingredient. It's scientifically, it's science-based here, we're not just woo-wooing here, scientifically shown to protect and restore that endothelial inside layer, the one that is susceptible to all those things that I mentioned. And this is one I take every single morning, three a day, and then I take the Vasconox HP. This one I take on the days that I work out. It provides nitric oxide support for 24 hours. It helps your blood vessels open up, relax and open up to get blood vessels to where they need it the most.

Visit calroy.com slash DRG is c-a-l-r-o-y.com d-r-g when you're nasal breathing it's actually maintaining the optimal balance of co2 levels it's ensuring that hemoglobin releases oxygen efficiently to the muscles the organs and the brain basically you're optimizing your red blood cells. You're optimizing delivery of oxygen to all those really essential organs. What else? It actually reduces airway collapse and snoring. So I'll go into who shouldn't use mouth tape, but mouth breathing actually causes the tongue to fall back into the throat and it increases airway resistance and it leads to snoring and disrupted sleep. We know that. Whether your partner snores or you snore, we know how it feels. Mouth taping actually ensures that the tongue stays in place in its natural resting position against the palate and it prevents that obstructive collapse of the airway. And we see that. 2015 study in American Journal of Respiratory and Critical Care Medicine found that mouth breathers had a 40% higher likelihood of developing obstructive sleep apnea compared to those out there that breathe from the nose. And there are scientifically proven benefits of mouth taping. We know in the science, it improves sleep, reduces snoring, nasal breathing is going to decrease that airway resistance. It's going to allow deeper, more restful sleep. Oxygen is flowing. Airways are open. We see that in the 2021 study in the Journal of Clinical Sleep Medicine actually found that individuals who practice nasal breathing, who mouth taped, experience a 25% reduction in nighttime awakenings reported. And it improved daytime energy levels overall. It's going to reduce snoring. The 2019 study in sleep and breathing found that mouth taping reduced snoring intensity by an average of 38% in chronic snores. It prevents sleep apnea and enhances oxygenation. Obstructive sleep apnea, we know, is linked to mouth breathing because the airway collapses more easily than when the mouth is open. And in a 2021 study and respiratory medicine, they looked at this. We saw that mouth breathers had a higher apnea score, meaning that they experience more frequent lapses in breathing, right? They're breathing and then they stop breathing. They're breathing and then they stop breathing. But when you close the mouth, nasal breathing is reducing apnea episodes, and you're getting more oxygen levels during sleep. But what about athletic performance? Does actually mouth taping help athletic performance? Well, nasal breathing improves VO2 max, VO2 max being a marker, a huge marker of longevity and mortality, right? If your VO2 max is elevated, you know that you're in a good place as you get older. Now, VO2 max is basically showing us how efficiently is the body using oxygen during exercise. A 2018 study in their International Journal of Kinesiology and Sports Science, they found that athletes who train with nasal breathing for six weeks improve their endurance performance by 15% compared to the mouth breathers. 15% when you train by nasal breathing. And if you don't know this, mouth taping is incredible because it improves oral health and prevents cavities. And mouth breathing may be the cause of your cavities. When you mouth tape, it improves overall health and prevents cavities. When you mouth breathe at night, it's drying out saliva. It's creating that environment where harmful bacteria love to flourish, which leads to tooth decay, gum disease, and bad breath through the day. And we see it in the research. A 2019 study in the Journal of Oral Rehabilitation found that mouth breathers had a significantly higher incidence of cavities and periodontal disease due to that chronic dry mouth while y'all be sleeping. And when you mouth tape at night, it prevents this because it keeps saliva production intact. It protects the oral bacteria and reduces that morning breath. Did you know that mouth breathers are typically more stress than nasal breathers? And when you mouth tape, it reduces anxiety and stress by activating that parasympathetic nervous system. When you nasal breathe, it stimulates the vagus nerve and it shifts the body from that fight or flight into that rest, digest, and recover mode. And a 2020 study in Frontiers in Psychology found that mouth breathers had significantly higher levels of cortisol, that stress hormone, compared to those that nasal breathe. When you mouth tape, it reinforces slow, controlled nasal breathing. You'll find that anxiety in your heart rate goes down while improving your overall mental clarity. So who should try mouth taping? Who should avoid it? Well, let's give a thumbs up. People who snore frequently should mouth tape. It helps reduce airway resistance. It keeps the tongue from blocking airflow. People who have mild sleep apnea should use mouth tape. It encourages nasal breathing. It's going to reduce apnea events. Athletes and high performers should use mouth tape. It enhances oxygenation, endurance, recovery. People with dry mouth should use mouth tape, preventing cavities and bad breath, overgrowing the bacteria. People with anxiety or high stress should use mouth tape. It supports calm breathing patterns overall. Who should not use mouth tape? Well, individuals with severe obstructive sleep apnea, if the episodes are severe, the mouth taping can actually worsen the issue. So you got to talk to your doctor first. People with nasal congestion or deviated septums, if you can't breathe through your nose, mouth taping could be a major, major issue. Children under five should not be using mouth taping. Young children should only attempt mouth taping under medical supervision. People with respiratory illnesses should not mouth tape. If you have severe asthma or chronic sinus infections, you got to talk to your doctor before anything. And how do we find a quality mouth tape, right? What do we need to look for? One, look for something that's hypoallergenic adhesive to avoid any skin irritation. You want to make sure it's flexible and breathable. So it allows for jaw movement and maybe some sort of porous breathing through it. Medical grade, you want to use medical grade material to prevent any allergic reactions. The removal shouldn't be aggressive, ripping on the skin or ripping on a beard. You want to make sure that you call the company and ask if they have any PFAS in their adhesive, or if that adhesive is PFAS or any adhesive chemicals or toxic adhesive chemicals free like PFAS. So how do you start doing it safely? Test nasal breathing first. Try breathing only through your nose for 10 minutes while you're awake. If you're uncomfortable, then you got to address that nasal congestion before doing anything. You can start by actually partially taping. Put a small little vertical strip in the center of your lips instead of covering your full mouth. Use a safe mouth tape. Don't use duct tape or non-medical adhesives. I use the X-shaped ones. Those are lightweight and designed for sleep. Monitor your sleep quality. If you have an aura ring or a whoop or any other measurables, if you feel worse when you wake up, headache, dizzy, shortness of breath, mouth taping might be an issue for you too. So mouth taping, is it fact or fiction? It's health fact. Only if it's used correctly though. And based on what we see in the scientific research, the clinical evidence, it's not just a wellness fad. It actually has some real benefit. It can help your sleep quality, snoring, reduction, oral health, even your athletic performance, even stress, right? So it may work. It might not be for everyone, especially we spoke about severe apnea, nasal congestion, deviated septum. It can do more harm than good if you're doing that, but make the choice for yourself. I've been mouth taping for five years now, four years now. I haven't had any cavities, which is really crazy. So, um, and I did have many of them every year. I didn't understand why I was eating so healthy, but mouth taping was really potent and beautiful. Anyway, mouth tape, if you feel called to it, but talk to your doctor, don't do it. If you any of the contraindications. And thank you for listening to this episode of Heal Myself."
