Mouth Taping for Sleep: Does It Work and Is It Safe?

Mouth taping for sleep means putting a strip of tape over your lips at night so you breathe through your nose. It's all over social media as a fix for snoring, dry mouth and poor sleep. This guide covers what mouth taping is, what the research actually found, the risks, who should not try it, and better first steps for snoring and mouth breathing.

The short answer: the evidence for mouth taping is thin. A 2025 systematic review found only 10 small studies with 213 people in total. Two showed some improvement in mild sleep apnoea, the rest showed no difference, and several raised safety concerns, including a risk of suffocation if your nose is blocked. The reviewers concluded the data doesn't support mouth taping for the general population. If you snore or might have sleep apnoea, see your GP before trying it.

What is mouth taping?

You place a piece of porous tape vertically or horizontally over your closed lips before bed. The aim is to keep your mouth shut so you breathe through your nose all night. Supporters claim it reduces snoring, dry mouth and morning bad breath, and improves sleep and energy.

The idea isn't silly. The Sleep Health Foundation notes that a blocked nose forces you to breathe through your mouth and raises your risk of snoring (source). The question is whether taping the mouth shut is a safe and effective way to change that.

What the research says

The best summary so far is a 2025 systematic review in PLOS One. The researchers screened 86 articles and found just 10 that met their criteria, with a total of 213 patients (source).

Finding	Detail
Studies showing benefit	2 of 10, both in people with mild sleep apnoea
Other studies	No meaningful difference from mouth taping
Safety concerns raised	4 studies discussed risks, including suffocation with nasal blockage or vomiting
Who was left out	Most studies excluded people with nasal blockage, the people most likely to try it at home
Conclusion	The data doesn't support mouth taping as a sound intervention for the general population

One of the positive studies, often cited online, tested a porous oral patch in people with mild sleep apnoea who breathed through their mouths. The Sleep Foundation notes it was small and that most other claimed benefits are anecdotal (source).

The risks

Mouth taping can seem harmless because it's only tape. The concerns are real, though:

• A blocked nose. If your nose blocks overnight from a cold, hay fever or a deviated septum, your mouth is your backup airway. Taping it shut removes that backup.
• Vomiting or reflux. The review authors flag a risk of asphyxiation if you vomit or regurgitate with your mouth sealed.
• Masking sleep apnoea. Quieter snoring can hide a serious condition that needs proper treatment.
• Skin irritation around the lips, and a sense of panic or anxiety for some people.
• Poorer sleep if you keep waking to check you can breathe.

Who should not try mouth taping

Based on the review and the Sleep Foundation's guidance, don't tape your mouth if you:

• Snore loudly, stop breathing or wake gasping, or might have sleep apnoea. Talk to your GP first.
• Often have a blocked nose, hay fever, sinus trouble or a cold.
• Have asthma, COPD or another breathing condition.
• Have reflux or are at risk of vomiting at night.
• Feel anxious or panicky with your mouth covered.
• Are a child. It hasn't been studied in children.

Better first steps for snoring and mouth breathing

If you're tempted by mouth taping because of snoring, start with the steps health services already recommend. healthdirect suggests sleeping on your side, avoiding alcohol for at least four hours before bed, losing weight if you're overweight, avoiding allergy triggers, and, where needed, devices such as mandibular advancement splints, CPAP or nasal dilator strips (source).

1. Sleep on your side. Snoring is almost always worse on the back. See the best sleeping position.
2. Treat a blocked nose. A pharmacist or GP can help with hay fever and congestion.
3. Cut evening alcohol, which relaxes the throat muscles.
4. Get checked for sleep apnoea if you snore loudly or feel unrefreshed. See the signs of sleep apnoea.

When to see your GP

See your GP if your snoring bothers you or your household, if someone has noticed you stop breathing, or if you wake gasping or choking. The Sleep Health Foundation notes that problem snoring may be an early warning sign of sleep apnoea, and your GP can refer you to a sleep specialist (source). Bring your partner along if you can, as they can describe what happens at night. This guide is general information, not medical advice.

Where the Sovune Nudge fits

We make the Sovune Nudge, a vibrating alarm wristband, so we're not neutral. It has nothing to do with breathing or snoring. Where it helps is in a bedroom where one person snores or sleeps lightly and the other has to get up early.

• Silent. No speaker and no sound, so it won't wake a partner who's finally asleep.
• Wakes you with vibration on your wrist, starting as a gentle tap and building through three intensity levels.
• Felt rather than heard, which matters if you sleep with earplugs. Each alarm lasts a full minute.
• Set on the band itself. No app, no phone, no pairing.

Quick answers

Does mouth taping stop snoring? The evidence is limited. Two small studies found improvements in mild sleep apnoea, but most studies found no difference.

Is mouth taping safe? Not for everyone. Reviewers flagged a risk of suffocation if your nose blocks or you vomit, and it can hide sleep apnoea.

Should I try mouth taping if I have sleep apnoea? Not on your own. Talk to your GP or sleep specialist about proven treatments.

What can I do instead? Sleep on your side, treat a blocked nose, avoid alcohol before bed and get checked if you snore loudly.
