Snoring is extremely common, and for many people it is simply an irritating noise that happens during sleep.
But it’s not always just a nuisance.
Sometimes it is linked to the way the throat or nose narrows during sleep. In some people, persistent loud snoring is also a sign of obstructive sleep apnoea, a condition in which breathing repeatedly stops or becomes restricted during sleep.
The important thing is not to panic every time someone snores.
It is to know the difference between ordinary snoring and the warning signs that deserve medical attention.
The NHS says it is very common and is not usually caused by anything serious. It also advises seeing a GP when it significantly affects everyday life or when there are signs such as breathing pauses, gasping, choking, or excessive daytime sleepiness. NHS
This guide explains what causes snoring, what may help, which treatments are available and when it could mean something more important is going on.
What Is Snoring?
Snoring happens when tissues in the mouth, throat or nose vibrate as you breathe while asleep.
During sleep, muscles in the upper airway relax. In some people, this narrows the airway. Air moving through the narrowed passage can make the surrounding tissues vibrate, producing the sound we recognise as snoring.
The exact anatomy varies from person to person.
Your tongue, soft palate, throat or nasal airway can all contribute.
That is why no single treatment works for everyone.
Why Do Some People Snore More Than Others?
Several factors can make it more likely.
These include:
- sleeping on your back
- being overweight
- smoking
- drinking too much alcohol
- nasal congestion or a narrow nasal airway
- the natural shape of the mouth, throat or jaw
- some medicines, including sleeping pills
- getting older
The NHS identifies several of these factors as common contributors to snoring. NHS
This is also why simply buying a gadget without considering the cause may not help.
Is Snoring a Sign of Poor Oxygen Levels?
Not necessarily.
An older Natural Health Kingdom article suggested that it meant the brain wasn’t getting enough oxygen and that the heart therefore had to work harder.
That is too simplistic and should not be repeated.
Ordinary snoring does not automatically mean that your blood oxygen level is dangerously low.
The concern arises when it is part of obstructive sleep apnoea, where breathing repeatedly becomes restricted or stops during sleep.
That is a different medical problem.
What Is Obstructive Sleep Apnoea?
Obstructive sleep apnoea (OSA) occurs when the upper airway becomes too narrow or closes repeatedly during sleep.
Breathing may stop completely for periods of time or become greatly reduced.
The person may briefly wake or move into lighter sleep to reopen the airway, often without remembering it the next morning.
The NHS lists loud snoring, witnessed pauses in breathing, gasping or choking during sleep and excessive daytime tiredness among the main warning signs.
NICE recommends assessing people for obstructive sleep apnoea when combinations of symptoms such as snoring, witnessed apnoeas, unrefreshing sleep, morning headaches, excessive sleepiness, choking during sleep and fragmented sleep are present. NICE
How Can You Tell the Difference Between Snoring and Sleep Apnoea?
You cannot reliably diagnose sleep apnoea just from the sound of it.
But there are warning signs.
Someone may have sleep apnoea if their partner notices:
- breathing that repeatedly stops and starts
- gasping, snorting or choking during sleep
- very loud or irregular snoring
- frequent restless sleep
The person themselves may notice:
- excessive daytime sleepiness
- waking headaches
- difficulty concentrating
- unrefreshing sleep
- mood changes
These symptoms do not prove sleep apnoea, but they are good reasons to seek medical assessment.
Can Sleeping on Your Side Reduce Snoring?
Yes, it can help some people.
Snoring is more likely when you sleep on your back because your tongue and other tissues can move back and narrow the airway.
The NHS recommends sleeping on your side and suggests practical aids, such as a special pillow or bed wedge, if needed.
Some people use a simple reminder system to avoid rolling onto their back.
The important point is that positional changes are most useful when position is actually contributing to the problem.
Can Losing Weight Help Snoring?
It can, when excess weight is contributing to airway narrowing.
The NHS specifically recommends losing weight, if you are overweight, as one lifestyle measure that may reduce snoring.
That does not mean everyone who snores needs to lose weight.
People of different body sizes can snore.
Weight is simply one of several factors that can influence the airway.
Can Alcohol Make Snoring Worse?
Yes.
Alcohol relaxes muscles in the upper airway, which can make it more likely or more pronounced.
The NHS advises avoiding too much alcohol when trying to reduce snoring and notes that it can contribute to the problem.
This is especially relevant if you notice your snoring worsens after drinking in the evening.
Reducing alcohol before bedtime can therefore be a worthwhile experiment.
Can Smoking Cause Snoring?
Smoking can contribute to inflammation and irritation of the airway.
The NHS lists smoking among factors associated with snoring and recommends stopping smoking as part of lifestyle management. NHS
Stopping smoking brings benefits far beyond snoring, so it is one of those changes where the upside extends well beyond better sleep.
What About Sleeping Pills?
Some sleeping medicines can make it worse.
The NHS advises not to take sleeping pills unless recommended by a doctor, because they can sometimes contribute to snoring.
If you use sleeping medication and have developed or noticed worsening snoring, discuss this with the person who prescribed it rather than simply stopping prescribed treatment without advice.
Can a Blocked Nose Cause Snoring?
Yes.
A blocked or narrow nasal airway can make it harder to breathe comfortably through the nose during sleep.
The NHS lists nasal dilators, nasal strips and, in appropriate situations, treatments that reduce swelling inside the nose among possible options when nasal blockage contributes to snoring.
But the right treatment depends on the cause of the blockage.
Persistent nasal obstruction may need its own assessment.
Do Nasal Strips Work?
Nasal strips and nasal dilators can help some people when nasal narrowing contributes to the problem.
They work mechanically by helping keep the nasal passages open.
They are not treatments for obstructive sleep apnoea.
If your main problem is repeated pauses in breathing rather than simple nasal blockage, a nasal strip is not a substitute for proper assessment.
What About Mouthpieces?
Some anti-snoring mouthpieces are designed to move the lower jaw forward during sleep.
These are called mandibular advancement devices.
The NHS lists devices that help bring the tongue forward as one possible treatment when the tongue contributes to airway narrowing.
Oral appliance therapy also has an established role in appropriate adults with obstructive sleep apnoea and in diagnosed primary snoring. The American Academy of Sleep Medicine recommends that qualified dental professionals provide custom, titratable oral appliances when oral appliance therapy is prescribed. AASM
This is important because not every cheap online anti-snoring mouthguard is equivalent to a properly fitted medical device.
Can a CPAP Machine Help Snoring?
Yes, but CPAP is primarily a treatment for obstructive sleep apnoea, not something that everyone with ordinary snoring needs.
CPAP uses positive airway pressure to help keep the airway open during sleep.
The American Academy of Sleep Medicine recommends CPAP or auto-adjusting PAP for ongoing treatment of adults with obstructive sleep apnoea. AASM
The NHS also identifies CPAP as a common treatment for sleep apnoea.
If someone is snoring because they have untreated sleep apnoea, treating the underlying condition matters far more than trying to make the it quieter.
What About Anti-Snoring Sprays and Gadgets?
Be cautious.
There is no reason to assume that an anti-snoring spray, magnetic device, mouth tape product, nose clip or vibrating gadget will work simply because the packaging says it will.
Some products may help particular causes of it.
Others may do very little.
The first question should always be:
What is causing the problem?
A product that helps nasal blockage is unlikely to solve snoring caused by the tongue or throat.
And a gadget that makes the sound quieter does not necessarily treat obstructive sleep apnoea.
Does Mouth Taping Stop Snoring?
Mouth taping has become fashionable online, but it should not be treated as a universal cure.
Snoring can have several causes, including problems in the nose and throat.
Forcing the mouth closed without understanding why someone is snoring is not a sensible substitute for assessment.
It is particularly inappropriate as a DIY approach when somebody has possible obstructive sleep apnoea or significant nasal obstruction.
Can Exercises Reduce Snoring?
Exercises involving the tongue, mouth and upper airway are sometimes promoted as anti-snoring techniques.
Some research exists on oropharyngeal exercises, but they should not be presented as a guaranteed cure.
The problem has many possible causes, and evidence quality varies across interventions.
If exercises are suggested, view them as one part of a broader approach rather than a replacement for medical evaluation when sleep apnoea is suspected.
Can You Stop Snoring Permanently?
Not necessarily.
It may improve when you address the cause.
For example, reducing alcohol, changing sleeping position, treating nasal congestion or managing excess weight may reduce the problem in some people.
But anatomy, age and other factors can change over time.
The NHS notes that some treatments can help but that surgery does not always work and snoring can return.
That is why promises of a “permanent cure” deserve caution.
When Should You See a GP About Snoring?
The NHS recommends speaking to a GP when lifestyle measures aren’t helping, when snoring significantly affects you or your partner, or when symptoms suggest sleep apnoea.
You should take it particularly seriously if someone tells you that your breathing:
stops and starts
or that you:
gasp, snort or choke during sleep.
Persistent excessive daytime sleepiness is another important reason to seek assessment.
How Is Sleep Apnoea Diagnosed?
A GP or sleep specialist may ask detailed questions about your sleep, symptoms and general health.
You may then be referred for sleep testing.
The NHS says that testing can often take place at home using equipment that measures breathing and other signals overnight.
NICE also provides specific recommendations for assessing and diagnosing obstructive sleep apnoea.
This matters because you cannot reliably tell how severe sleep apnoea is simply by listening to somebody snore.
What Happens If You Are Diagnosed With Sleep Apnoea?
Treatment depends on the person and the severity of the condition.
Lifestyle measures can sometimes help, including weight management, stopping smoking and reducing alcohol.
Many people with significant obstructive sleep apnoea are treated with CPAP or another positive airway pressure device.
Custom oral appliances are another option for some adults, particularly when CPAP is not tolerated or an alternative is preferred.
Treatment targets the underlying breathing problem, not just the noise.
Why Does Sleep Apnoea Matter?
Untreated obstructive sleep apnoea can cause more than disturbed sleep.
The NHS lists associations with high blood pressure, cardiovascular disease, type 2 diabetes, mood problems and an increased risk of accidents caused by tiredness.
That is why recognising warning signs is important.
Snoring on its own is usually not an emergency.
When it is combined with repeated breathing pauses and significant daytime sleepiness, it deserves proper attention.
What About Surgery for Snoring?
Surgery is sometimes considered when other treatments do not help, and there is a clear anatomical reason.
But it is not automatically a permanent solution.
The NHS notes that surgery does not always work and that it can return afterwards.
Surgery should therefore be considered carefully rather than treated as the obvious next step.
Six Sensible Ways to Try to Reduce Snoring
If your snoring is not accompanied by warning signs of sleep apnoea, sensible first steps include:
1. Try sleeping on your side.
This can help if sleeping on your back contributes to airway narrowing.
2. Reduce alcohol, especially in the evening.
Alcohol can make airway relaxation more pronounced.
3. Stop smoking.
This can reduce airway irritation and greatly benefit overall health.
4. Address nasal blockage.
If a blocked nose contributes to your snoring, appropriate nasal treatment may help.
5. Consider weight management where appropriate.
This may reduce snoring when excess weight is contributing to airway narrowing.
6. Review medicines with a professional when relevant.
Some sleeping medicines can worsen snoring.
These measures are simple, but they are much more sensible than buying six random gadgets and hoping for the best.
What Should You Not Assume About Snoring?
Do not assume that:
it always means sleep apnoea.
It does not.
Do not assume that:
it is never important.
It can be a warning sign of sleep apnoea.
Do not assume that:
a louder product is a better treatment.
The cause matters more than the marketing.
And do not assume that:
making the snoring quieter means the breathing problem is fixed.
That distinction matters especially when sleep apnoea may be involved.
The Bigger Picture
Snoring can be funny in a cartoon and incredibly frustrating at three o’clock in the morning.
But medically, it deserves a sensible middle ground.
Most is not caused by something dangerous.
At the same time, persistent loud snoring accompanied by breathing pauses, gasping, choking or excessive daytime sleepiness should not be dismissed.
The goal is not to find the most expensive gadget.
It is to work out why you are snoring.
Sometimes the answer really is straightforward: change your sleeping position, reduce alcohol, stop smoking, address nasal congestion or manage weight where appropriate.
Sometimes the answer is an oral appliance or another targeted treatment.
Sometimes it is a clue that obstructive sleep apnoea needs to be assessed and treated.
That is why the most useful anti-snoring advice is not “try these six miracle treatments”.
It is:
Find the cause. Treat the cause. And don’t ignore the warning signs.
