QUICK ANSWER

What does mouth tape actually do?

Mouth tape is an adhesive product designed to encourage the lips to remain closed during sleep. It may reduce mouth opening, mouth leak and morning dry mouth in selected adults who can already breathe comfortably through their nose. Evidence is still limited, and mouth taping should not be presented as a general cure for snoring, poor sleep, anxiety, low oxygen or obstructive sleep apnoea. It should never be used to force nasal breathing through a blocked or unreliable nasal airway.

What is mouth tape?

Mouth tape is a skin-safe adhesive strip or patch worn across or around the lips during sleep. Its purpose is to discourage the mouth from falling open while still allowing the user to remove the product independently.

Different designs include small vertical strips, full-width strips, porous patches, slit-style products and elastic designs that surround rather than fully cover the lips.

Why has mouth taping become popular?

Interest has grown alongside wider discussion of nasal breathing, sleep optimisation and snoring. Social media has amplified the practice, often with claims that go well beyond the available evidence.

The most plausible use is modest: helping selected people keep their lips together when they already have a clear nasal airway. That is very different from treating a sleep disorder or correcting the reason they mouth breathe.

Mouth tape versus nasal breathing training

Breathing training is an awake behavioural practice. Mouth tape is a physical prompt used during sleep. Tape does not retrain the brain, strengthen the airway or permanently change breathing patterns by itself.

Mouth tape versus a chin strap

A chin strap supports the lower jaw from outside the face. Mouth tape acts directly at the lips. Both may reduce mouth opening or mouth leak in selected settings, but neither should be used to bypass untreated nasal obstruction.

Mouth tape versus nose strips

1

Mouth tape

Encourages the lips to remain closed. It does not open the nose.

2

Nose strips

Mechanically support the nasal sidewalls. They do not keep the mouth closed.

3

Using both

May suit selected adults only when nasal breathing is already clear and comfortable.

How does mouth tape work?

The tape provides light resistance to lip separation. In suitable users, this may reduce habitual mouth opening, limit air escaping through the lips and encourage breathing through the nose.

It does not physically prevent every form of oral airflow. Research has described “mouth puffing,” where air may still escape despite the lips being taped.

The most accurate claim: mouth tape may encourage lip closure and reduce mouth leak in selected people. It does not guarantee continuous nasal breathing, cure airway collapse or prove that breathing is safe during sleep.

What mouth tape does not do

  • It does not open a blocked nose.
  • It does not treat allergies or sinusitis.
  • It does not straighten a deviated septum.
  • It does not remove enlarged adenoids or nasal polyps.
  • It does not enlarge the lungs.
  • It does not add oxygen to the blood.
  • It does not reliably cure snoring.
  • It does not replace CPAP or an oral appliance.
  • It does not diagnose or cure obstructive sleep apnoea.

Why nasal breathing matters

The nose filters, warms and humidifies inhaled air. It also provides resistance that helps regulate airflow. However, mouth breathing is sometimes a necessary backup route when nasal airflow is impaired.

Closing the mouth without checking nasal patency can remove that backup route, which is one reason indiscriminate use is not recommended.

What does the research say about mouth tape?

Research is still limited and includes small pilot studies, selected patient groups and different products. A 2025 systematic review concluded that evidence for broad clinical use remains insufficient and raised concerns about indiscriminate use, particularly where nasal obstruction or sleep-disordered breathing is present.

Outcome What evidence suggests How to interpret it
Lip closure and mouth leak Mechanical closure can reduce some forms of mouth opening and leak. This is the most direct and plausible effect.
Morning dry mouth Some users may experience less dryness if open-mouth breathing was a major cause. Dry mouth has many other causes, including medicines and salivary disorders.
Snoring Small studies suggest possible benefit in selected mouth breathers. Snoring has many causes, so results are unlikely to generalise.
Mild OSA A preliminary study reported improvement in selected mouth breathers with mild OSA. This does not establish mouth tape as a routine treatment.
OSA more broadly Recent reviews find evidence too limited for general clinical recommendations and highlight potential risk. Suspected OSA needs proper diagnosis and treatment.
CPAP mouth leak A 2025 clinical study reported improved CPAP adherence in selected mouth breathers using tape. This should be clinician-guided and not assumed safe for every CPAP user.
Asthma control A randomised study found no benefit. Mouth tape is not an asthma treatment.
Oxygen, metabolism and facial structure Strong claims are not supported by high-quality evidence. Avoid exaggerated wellness claims.

Why a positive small study is not a universal recommendation

A study may include carefully selected participants with mild disease, verified nasal airflow and clinical supervision. That does not mean the same result applies to someone with severe OSA, nasal obstruction, respiratory disease, alcohol intoxication or no diagnosis.

What current reviews agree on

The evidence base is small, patient selection matters, nasal obstruction is a central safety concern and larger controlled studies are needed.

Evidence-first positioning: mouth tape may be a useful lip-closure aid for selected adults. Claims that it cures sleep apnoea, guarantees deeper sleep, increases oxygen, reshapes the face or produces broad health benefits are not supported.

Why do people breathe through their mouth at night?

Mouth breathing is a behaviour or compensation, not a single diagnosis. Before trying to stop it, work out why it is happening.

Blocked or narrow nasal airway

Allergies, colds, sinus inflammation, enlarged turbinates, a deviated septum, nasal valve collapse and polyps can make nasal breathing difficult.

Habit

Some people continue to sleep with their mouth open even when the nose is clear, particularly after years of congestion or habitual jaw posture.

Sleep apnoea and upper-airway collapse

Mouth opening can occur as part of obstructive sleep apnoea. In some people, oral breathing may also be a backup route around nasal or velopharyngeal obstruction.

Alcohol and sedatives

Alcohol and sedating medicines can reduce upper-airway muscle tone and increase snoring or mouth opening.

Sleeping position

Back sleeping can worsen jaw opening and snoring in some people.

Jaw, tongue and facial anatomy

Jaw position, tongue posture and airway shape can influence whether the mouth opens during sleep.

CPAP mouth leak

People using a nasal CPAP mask may leak pressurised air through the mouth. This should be discussed with the treating sleep service because mask style, pressure, humidification and nasal treatment may all matter.

How to check whether your nose is ready

Can you breathe comfortably through both nostrils while sitting quietly?
If no, do not use mouth tape.
Can you keep your lips closed for several minutes without air hunger?
If no, investigate nasal airflow or breathing symptoms first.
Do you have persistent one-sided blockage, nasal bleeding, reduced smell or facial symptoms?
If yes, arrange medical assessment.
Do you snore loudly, gasp, choke or have witnessed breathing pauses?
If yes, seek a sleep assessment before experimenting.
Can you remove the tape immediately and independently?
If no, do not use it.

Mouth tape for dry mouth

Sleeping with the mouth open can increase evaporation and leave the mouth or throat dry. Encouraging lip closure may help when open-mouth breathing is the main cause.

However, persistent dry mouth can also result from medicines, dehydration, salivary-gland problems, autoimmune disease, diabetes, smoking, alcohol, anxiety or cancer treatment.

Why dry mouth matters

Saliva protects teeth and oral tissues. Persistent dry mouth can increase discomfort, bad breath, tooth decay, gum problems and difficulty speaking or swallowing.

When mouth tape is unlikely to fix dry mouth

  • You have dryness throughout the day.
  • You take medicines known to reduce saliva.
  • You have painful, cracked or burning oral tissues.
  • You experience difficulty swallowing.
  • You have ongoing thirst, frequent urination or unexplained fatigue.
  • You use CPAP without adequate humidification.

Mouth tape for snoring

Snoring is caused by vibration of tissues in a narrowed upper airway. Mouth opening can contribute, but the tongue, soft palate, throat, nose, body position, alcohol and body weight can all matter.

Small studies suggest mouth tape may reduce snoring in selected mouth breathers, but this should not be generalised to all snorers.

Who may be more likely to notice a benefit?

  • Adults who have a clear nose and primarily snore with the mouth open.
  • People whose snoring is mild and positional.
  • People without warning signs of sleep apnoea.
  • People who can comfortably trial lip closure while awake.

Who needs assessment instead?

Arrange a sleep assessment for:

  • Loud habitual snoring.
  • Witnessed breathing pauses.
  • Gasping or choking during sleep.
  • Marked daytime sleepiness.
  • Morning headaches.
  • High blood pressure with suspected sleep-disordered breathing.
  • Falling asleep while driving or during routine activities.

Mouth tape and obstructive sleep apnoea

Obstructive sleep apnoea occurs when the upper airway repeatedly narrows or closes during sleep. It can reduce oxygen, fragment sleep and increase health and safety risks.

A preliminary study in selected mouth breathers with mild OSA reported improvements after mouth taping. More recent reviews caution that evidence remains limited and that closing the mouth may be harmful in people who need oral airflow to bypass nasal or upper-airway obstruction.

Why mouth tape is not a substitute for OSA treatment

  • It does not reliably prevent throat collapse.
  • It does not provide airway pressure like CPAP.
  • It does not reposition the jaw like a fitted oral appliance.
  • It does not confirm that oxygen and breathing are normal.
  • It can conceal a symptom without treating the underlying disorder.

Evidence-based OSA treatments may include

  • CPAP or other positive airway pressure therapy.
  • A dentist-fitted mandibular advancement device for suitable patients.
  • Weight management where relevant.
  • Positional therapy.
  • Treatment of nasal obstruction.
  • Surgery in selected cases.
Do not use mouth tape as a self-treatment for suspected or diagnosed sleep apnoea unless your treating sleep clinician has specifically included it in your plan.

Mouth tape and CPAP

Mouth leak can reduce comfort and treatment effectiveness when using a nasal CPAP mask. A 2025 study reported improved adherence among selected patients using mouth tape, but this does not make it appropriate for every CPAP user.

Check these first

  • Is the nasal mask fitted correctly?
  • Is nasal congestion being treated?
  • Is humidification adequate?
  • Would a full-face mask be more appropriate?
  • Are pressure settings and comfort features optimised?
  • Has the sleep service confirmed that lip closure is safe?

Why clinician guidance matters

CPAP users may have moderate or severe sleep apnoea, complex airway anatomy or pressure-related side effects. Mouth tape can interact with mask leak, pressure delivery and comfort, so it should be discussed with the treating team.

Mouth tape and sleep quality

Some users report fewer dry-mouth awakenings or a more comfortable morning. Those experiences are valid, but they do not prove improved sleep architecture, oxygenation or treatment of a sleep disorder.

Sleep quality is also affected by stress, insomnia, room conditions, alcohol, caffeine, pain, medicines, sleep timing and medical conditions.

Mouth tape and anxiety

Some people feel calmer when breathing through the nose. Others experience anxiety, claustrophobia or panic when the lips are restricted.

Do not push through distress. A daytime breathing practice is a safer place to explore nasal breathing than forcing lip closure during sleep.

Mouth tape for sport or daytime training

Using mouth tape during exercise can restrict a normal backup route when ventilation demand rises. Hard exercise naturally requires mouth breathing for many people.

Do not tape the mouth during intense exercise, swimming, driving, hazardous work or any activity where rapid unrestricted breathing and communication may be needed.

Mouth tape during illness

Do not use it during a cold, influenza, COVID-19, sinus infection, nausea, vomiting or any illness that reduces nasal airflow or increases aspiration risk.

Mouth tape during pregnancy

Pregnancy can increase nasal congestion and may also increase snoring or sleep-disordered breathing. Because nasal airflow may be unreliable and OSA risk can change, pregnant people should seek individual advice before using mouth tape.

Mouth tape for children

Children should not routinely use mouth tape. Mouth breathing, snoring or sleep disturbance in a child can be associated with enlarged adenoids, tonsils, allergies or paediatric OSA and requires assessment.

Types of mouth tape

Type Design Possible advantage Consideration
Vertical strip A narrow strip crosses the centre of the lips Less skin coverage and easier removal May allow side gaps or mouth puffing
Slit-style tape Wider tape with a central breathing slit Offers an emergency airflow route and easier communication Still requires a clear nose and independent removal
Full-width strip Covers most of the lip line Stronger lip-closure cue Greater skin coverage and potentially more anxiety
Porous oral patch Designed with breathable material or openings May feel less restrictive Evidence depends on the exact product and population
Elastic surround design Sits around the mouth rather than sealing directly across it May encourage closure while leaving the lips more accessible Fit and tension vary
General household tape Not designed for lips or overnight facial use None Avoid due to adhesive, removal and safety concerns

How to choose mouth tape

For first-time usersChoose a purpose-designed slit or small vertical format that is easy to remove.
For sensitive skinChoose a hypoallergenic skin adhesive and begin with a short awake test.
For facial hairA smaller central strip may make better contact than a wide patch.
For dry lipsAvoid applying over cracked, bleeding or inflamed skin.
For CPAPUse only with sleep-clinic guidance and confirm it does not interfere with treatment.
For nasal congestionDo not tape. Identify and treat the cause of obstruction first.

Why purpose-designed mouth tape is different

Products made for overnight lip use should use a skin-appropriate adhesive, predictable dimensions and clear instructions. Household duct tape, electrical tape and strong packaging tape are not suitable.

How to apply mouth tape more safely

Confirm nasal breathing first

Sit quietly with the lips closed for several minutes. Both nasal airflow and comfort should remain stable.

Complete an awake trial

Wear the product for 10 to 20 minutes while awake and seated. Confirm you can remove it instantly.

Clean and dry the skin

Remove lip balm, facial oil, moisturiser and makeup from the contact area.

Prepare the tape

Follow the product instructions. Some users reduce initial adhesion by briefly touching the strip to clean skin before application.

Relax the lips

Bring the lips together naturally without clenching the jaw or forcing the teeth together.

Apply gently

Use the intended orientation and avoid covering more skin than necessary.

Recheck comfort

Do not continue if you feel air hunger, panic, nausea, dizziness or significant resistance.

Remove slowly

In the morning, support the skin and peel gradually. Use warm water if needed.

How tight should mouth tape feel?

It should feel like a gentle reminder rather than a seal that forces the jaw shut. You should be able to remove it immediately with your fingers.

Should you fold a removal tab?

Where compatible with the product instructions, folding a small corner can make removal faster. Slit-style designs can also provide easier access.

How to remove mouth tape without hurting your skin

Peel slowly rather than pulling sharply. Warm water can loosen the adhesive. Stop use if the lips or surrounding skin become cracked, blistered or persistently irritated.

Mouth tape for sensitive skin

  • Patch-test on nearby facial skin before an overnight trial.
  • Use a purpose-designed hypoallergenic adhesive.
  • Avoid applying after exfoliation, shaving, retinoids or active skincare.
  • Do not use over eczema, dermatitis, cold sores or broken skin.
  • Shorten wear time if redness appears.
  • Stop if irritation persists beyond the morning.

Why tape may not stick

Problem Likely cause What to do
Edges lift quickly Lip balm, oil or moisturiser Clean and fully dry the skin
Tape releases overnight Saliva, facial hair or excessive movement Try a different size or purpose-designed format
Skin becomes red Adhesive sensitivity or forceful removal Stop, allow recovery and choose a gentler product
Tape feels suffocating Nasal resistance, anxiety or unsuitable design Remove immediately and do not retry until the cause is addressed
Dry mouth continues Cause is not simply open-mouth breathing Review medicines, hydration, oral health and medical causes
Snoring continues Snoring originates deeper in the airway Arrange assessment if habitual or associated with warning signs

Mouth tape safety checklist

Mouth tape is not appropriate simply because a person can tolerate it. Use this checklist before considering an overnight trial.

Are you a suitable candidate for a cautious trial?

Rate each statement from 0 to 2: 0 means no, 1 means uncertain and 2 means yes.

/2I breathe easily through my nose.
/2I have no current cold or congestion.
/2I have no OSA warning signs.
/2I can remove the tape immediately.
/2I am not intoxicated or sedated.
/2I have no nausea or vomiting risk.
/2My lip skin is healthy.
/2I completed an awake trial comfortably.

15–16: a cautious trial may be reasonable. 10–14: resolve uncertainties first. Below 10: do not use it until the relevant issue has been assessed.

Who should avoid mouth tape?

Do not use mouth tape if:

  • Your nose is blocked, unreliable or difficult to breathe through.
  • You have untreated or suspected obstructive sleep apnoea.
  • You are vomiting, nauseated or at risk of aspiration.
  • You are intoxicated or heavily sedated.
  • You cannot remove the product independently.
  • You have severe breathing, neuromuscular or cognitive impairment without specialist advice.
  • You have active lip sores, damaged skin or a severe adhesive allergy.
  • You are a young child.
  • You feel panicked, claustrophobic or air hungry when testing it.

What to do if you wake feeling breathless

Remove the tape immediately. Sit upright and assess your breathing. Seek urgent help for severe breathlessness, chest pain, blue lips, confusion or symptoms that do not settle promptly.

Emergency symptoms

Call emergency services for severe difficulty breathing, loss of consciousness, blue or grey lips, chest pain, severe confusion or inability to stay awake.

Common mouth-taping myths

“It increases oxygen”

There is no good evidence that routine mouth taping raises oxygen levels in healthy users.

“It cures sleep apnoea”

Small selected studies do not establish it as a general OSA treatment.

“Everyone should nasal-breathe all night”

Oral airflow can be an important backup route when the nasal airway is obstructed.

“It reshapes your jaw or face”

Overnight adhesive does not reliably remodel adult facial structure.

“It prevents every form of mouth breathing”

Mouth puffing and air leakage can still occur.

“More tape is safer”

Stronger sealing can increase anxiety, skin injury and risk.

Mouth tape versus other solutions

Option What it addresses When it may help Key limitation
Mouth tape Lip opening or mouth leak Selected adults with reliable nasal breathing Does not treat airway obstruction
Nose strip Nasal valve narrowing Front-of-nose resistance Does not keep lips closed
Saline Dryness, mucus and allergens Mild congestion and nasal care Does not correct major anatomy
Intranasal treatment Inflammation or allergy Clinician or pharmacist-guided rhinitis care Requires correct diagnosis and technique
CPAP Sleep-related airway collapse Diagnosed OSA Requires prescription, setup and adherence
Mandibular advancement device Jaw and tongue position Selected snoring or OSA patients Requires professional fitting
Positional therapy Back-sleeping-related obstruction Positional snoring or OSA Not sufficient for everyone

Frequently asked questions about mouth tape

Does mouth tape actually work?
It may encourage lip closure and reduce mouth leak in selected adults with clear nasal breathing. Evidence for broader sleep and health benefits remains limited.
Is mouth tape safe?
It may be tolerated by selected adults, but it is not suitable for everyone. Nasal airflow, sleep-apnoea risk, ability to remove it and skin health all matter.
Can mouth tape improve sleep?
Some users report less dry mouth or improved comfort, but there is not enough evidence to claim it reliably improves overall sleep quality.
Does mouth tape increase oxygen?
There is no strong evidence that routine mouth taping increases blood oxygen in healthy users.
Does mouth tape cure sleep apnoea?
No. It is not an established replacement for CPAP, an oral appliance or other evidence-based OSA treatment.
Can mouth tape make sleep apnoea worse?
Potentially, especially if oral airflow is compensating for nasal or upper-airway obstruction. People with suspected OSA should seek assessment first.
Does mouth tape stop snoring?
It may reduce snoring in selected people whose snoring is linked to open-mouth breathing, but many snorers will not improve.
Can I mouth tape if I snore?
Habitual or loud snoring should be assessed for sleep apnoea before experimenting with mouth tape.
Can I use mouth tape with a blocked nose?
No. Mouth tape should never be used to force nasal breathing through an obstructed nose.
Can I use mouth tape during a cold?
No. Avoid it whenever illness or congestion makes nasal airflow less reliable.
Can mouth tape reduce dry mouth?
It may help if open-mouth breathing is the main cause, but persistent dry mouth has many other possible causes.
Why do I still wake with a dry mouth after taping?
You may still leak air, or dryness may be caused by medicines, dehydration, salivary problems, CPAP settings or another condition.
Can mouth tape improve bad breath?
Reducing overnight dryness may help some people, but bad breath can also come from dental disease, gum disease, reflux, infection or other causes.
Can I use mouth tape every night?
Only if nasal breathing remains clear, the skin tolerates it and no safety concerns are present. Stop whenever congestion or illness develops.
How long should I wear mouth tape?
Follow the product instructions. It is generally intended for one sleep period and should be removed on waking.
Can I reuse mouth tape?
No. Single-use adhesive products should be discarded after removal.
How do I test mouth tape before sleeping?
Wear it while awake and seated for 10 to 20 minutes, confirm comfortable nasal breathing and practise immediate removal.
How should mouth tape feel?
It should feel like a light reminder to keep the lips together, not an airtight restraint.
Should mouth tape fully seal the lips?
A complete seal is not necessary for every design and may feel more restrictive. Follow the specific product instructions.
Is slit mouth tape safer?
A slit can offer easier airflow, communication and removal, but it does not remove the need for clear nasal breathing and proper screening.
Can I use ordinary tape on my mouth?
No. Use only a purpose-designed skin product. Strong household adhesives can damage the lips and surrounding skin.
Can mouth tape cause skin irritation?
Yes. Adhesive sensitivity, active skincare and forceful removal can cause redness or injury.
How do I remove mouth tape without pain?
Peel slowly while supporting the skin. Warm water can help loosen the adhesive.
Can mouth tape damage my lips?
It can if applied over cracked skin, removed forcefully or used with an unsuitable adhesive.
Can I use lip balm under mouth tape?
Lip balm often reduces adhesion. Protect the lips earlier in the evening and apply tape only to clean, dry contact areas.
Can people with facial hair use mouth tape?
Yes, but a smaller vertical design may adhere more reliably than a wide strip across dense hair.
Can children use mouth tape?
Mouth tape should not be routinely used in children. Childhood mouth breathing and snoring require medical assessment.
Can teenagers use mouth tape?
Only after the cause of mouth breathing has been assessed and with appropriate adult and professional guidance.
Can pregnant people use mouth tape?
Pregnancy can cause nasal congestion and increase sleep-disordered breathing risk, so individual medical advice is appropriate.
Can I use mouth tape if I have asthma?
A randomised study found no improvement in asthma control. People with respiratory disease should seek clinician advice before use.
Can I use mouth tape if I have COPD?
Not without advice from the treating clinician. Breathing reserve and overnight oxygen or ventilation may be concerns.
Can I use mouth tape if I have anxiety?
Some people find it distressing or claustrophobic. Do not use it if it triggers panic or air hunger.
Can I use mouth tape after drinking alcohol?
No. Alcohol can worsen airway collapse, reduce awareness and impair the ability to respond or remove the tape.
Can I use mouth tape with sleeping tablets?
Not without medical advice. Sedating medicines can reduce awareness and affect breathing.
Can I use mouth tape if I feel nauseated?
No. Avoid it when there is any vomiting or aspiration risk.
Can I use mouth tape with CPAP?
Some selected CPAP users may benefit, but it should be discussed with the treating sleep team.
Does mouth tape prevent CPAP leaks?
It may reduce oral leak in selected nasal-mask users, but mask fit, pressure, humidification and nasal obstruction should also be reviewed.
Is a chin strap better than mouth tape?
The better option depends on why the mouth opens, CPAP setup, comfort and clinician advice.
Can I use mouth tape with nose strips?
Some adults use both, but only when nasal airflow is already comfortable and there are no OSA or safety concerns.
Should I try nose strips before mouth tape?
When nasal valve resistance is present, improving nasal comfort first is more sensible than forcing the mouth closed.
Does mouth tape train nasal breathing?
It acts as a temporary physical cue. It does not guarantee permanent habit change after removal.
Can mouth tape reshape my face?
There is no good evidence that overnight mouth tape remodels the adult face or jaw.
Can mouth tape improve jawline definition?
No reliable clinical evidence supports this claim.
Can mouth tape improve nitric oxide?
Nasal breathing involves nasal nitric oxide, but this does not prove that mouth tape produces meaningful systemic health effects.
Can mouth tape improve athletic performance?
There is no good evidence that sleeping with mouth tape directly improves athletic performance.
Can I exercise with my mouth taped?
Do not use mouth tape during hard exercise or activities where unrestricted breathing and communication are important.
Why does my mouth still puff with tape?
Pressure can briefly separate parts of the lips or force air around the tape. Mouth taping does not guarantee complete oral airflow prevention.
Why do I wake up and remove the tape?
The tape may feel restrictive, your nose may block during sleep or your body may be responding to airflow discomfort.
Why does my nose block after I fall asleep?
The nasal cycle, lying position, allergies, dry air and structural narrowing can make nighttime congestion worse.
What if one nostril is always blocked?
Persistent one-sided obstruction should be medically assessed before mouth taping.
When should I stop using mouth tape?
Stop for breathing discomfort, congestion, illness, nausea, panic, skin injury or any new sleep-apnoea symptoms.
When should I see a doctor?
Seek assessment for loud habitual snoring, witnessed pauses, daytime sleepiness, persistent dry mouth, chronic nasal blockage or breathing distress.
