Important: This page is for general information only. It cannot diagnose snoring or sleep apnoea or tell you exactly which tests or treatments you need. Always speak to your GP, practice nurse or specialist if you are worried about breathing at night, heavy snoring, witnessed pauses in breathing, or severe daytime sleepiness. Call 999 immediately if someone is unresponsive, has stopped breathing, has blue lips, or you are worried about a heart attack or stroke.

Snoring: common, often harmless – but not always

Many people snore at least sometimes. Snoring happens when air has to squeeze through narrowed passages at the back of the throat and nose, causing the soft tissues there to vibrate. Common reasons include:

• Sleeping on your back so the tongue falls backwards.
• A blocked or stuffy nose from colds, allergies or structural changes.
• Being overweight, especially with a larger neck or tummy.
• Drinking alcohol in the evening, which relaxes throat muscles.
• Certain medicines, such as strong painkillers or sedatives, that relax breathing muscles.

For some people, snoring is mainly a social problem: partners lose sleep, holidays are awkward, and there may be jokes or embarrassment. But in others, snoring is part of a more serious pattern where breathing actually stops or becomes very shallow many times a night. This is called sleep apnoea.

What is sleep apnoea?

“Apnoea” means “no breath”. In obstructive sleep apnoea, the most common type, the airway at the back of the throat repeatedly narrows or closes during sleep. The chest and diaphragm still try to breathe, but air cannot get through easily.

Typical features can include:

• Loud, regular snoring – often with quiet pauses.
• Pauses in breathing – other people may see or hear you stop breathing for several seconds.
• A gasping, choking or snorting sound when breathing starts again.

Each time this happens, oxygen levels in the blood can drop a little. The brain briefly wakes you just enough to reopen the airway – not enough to remember, but enough to disturb deep, restorative sleep. This can occur dozens of times an hour in moderate or severe cases.

Over months and years, this pattern can strain the heart, blood vessels and brain, and strongly affect mood, energy and safety.

Why sleep apnoea matters more in later life

Sleep apnoea can occur at any age, but certain features of later life make it especially important to recognise:

• Heart health. Repeated drops in oxygen and surges of stress hormones can raise blood pressure and put strain on the heart. Over time, untreated sleep apnoea is linked with a higher risk of high blood pressure, heart rhythm problems, heart attacks and strokes.
• Brain health and mood. Broken sleep and night-time oxygen dips can affect memory, concentration and mood. In older adults, this may be mistaken for “just getting older” or dementia alone.
• Falls and accidents. Daytime sleepiness, slow reactions and morning headaches can increase the risk of falls, car accidents or injuries in the home.
• Existing conditions. Sleep apnoea can worsen diabetes control, heart failure and some lung conditions, making overall health harder to manage.

The good news is that treatment can make a real difference, even in older adults: better daytime alertness, improved blood pressure in many cases, and safer nights for both you and your heart.

Signs your snoring might need checking

Not everyone who snores has sleep apnoea. However, you should talk to your GP if you (or your partner, family or carer) notice any of the following:

• Loud, regular snoring most nights, not just with colds or after a late night.
• Witnessed pauses in breathing – others notice you stop breathing for short spells, then gasp or snort.
• Waking up choking or gasping, or with a racing heart at night.
• Waking with morning headaches or feeling as if sleep has not refreshed you.
• Severe daytime sleepiness – nodding off while reading, watching television, in conversations, or as a passenger in a car.
• Needing frequent naps that are not explained by other illnesses or poor night-time habits alone.
• Night-time toilet trips plus snoring and pauses – sleep apnoea can sometimes trigger extra visits to the toilet at night.

Family members often spot patterns long before the person who snores does. If you are reading this as a partner or carer, your observations are valuable. You are not nagging; you are helping keep someone safer.

Who is more at risk of sleep apnoea?

Risk factors do not mean you will have sleep apnoea, only that it is more likely. Common ones include:

• Being overweight, especially with a larger neck size or tummy.
• Male sex – although women, especially after the menopause, are also affected and often under-diagnosed.
• Getting older – muscles around the airway can become less firm with age.
• Family history of sleep apnoea or loud snoring.
• Smoking or heavy alcohol use.
• Certain facial or jaw shapes, enlarged tonsils or nasal problems that narrow the airway.
• Use of sedative medicines – such as some sleeping tablets, strong painkillers (opioids), some epilepsy or mental health medicines.
• Conditions such as heart failure, stroke or neuromuscular disease – which can also be linked with central sleep apnoea, where the brain’s breathing drive is affected.

If several of these apply, it is even more important not to ignore loud snoring or witnessed pauses in breathing.

When is snoring an emergency?

Most snoring and sleep apnoea situations, even when important, are not emergencies. However, seek urgent help via 999 if:

• Someone is unconscious, difficult to rouse, or not breathing properly.
• You notice blue-tinged lips or skin and very shallow breathing.
• They wake with crushing chest pain, sudden weakness on one side, or difficulty speaking – possible heart attack or stroke.

These need immediate attention. You do not have to decide whether sleep apnoea is the cause – the priority is emergency care.

What happens at a sleep or breathing clinic?

Being sent to a “sleep clinic” can sound frightening. In reality, most assessments are calm, practical and focused on understanding your breathing pattern rather than judging you.

A typical pathway might include:

• Detailed questions about your sleep, snoring, daytime sleepiness, medical conditions and medicines.
• Physical examination – checking blood pressure, weight, neck size, airway, heart and lungs.
• Questionnaires about how likely you are to doze off in different situations.
• Sleep study – usually an overnight test. This may be done at home using a small portable monitor, or in hospital in some cases.

A sleep study often measures:

• Your breathing pattern and snoring sounds.
• Your oxygen levels through the night.
• Your heart rate and position in bed.

You are not expected to sleep perfectly during the test. Clinicians are used to “odd” nights of sleep in the lab or with wires attached; they can still gather useful information.

Common treatments – and what they feel like

Treatment depends on the cause and severity of the problem, and your other health conditions. Options may include:

• Continuous positive airway pressure (CPAP). A small machine gently blows air through a mask over your nose, or nose and mouth, keeping the airway open while you sleep.
• Mandibular advancement devices. Special mouthpieces that bring the lower jaw slightly forward, helping keep the airway open – typically used more in milder cases and often via dental services.
• Weight management support. Losing even a moderate amount of weight can significantly reduce snoring and apnoea in some people.
• Positioning advice. For example, avoiding sleeping flat on your back if this clearly worsens your apnoea – some people use pillows or devices to help stay on their side.
• Reviewing medicines that may worsen breathing at night, such as certain sedatives, where alternatives are available.
• Treating underlying conditions – such as heart failure, nasal obstruction or thyroid disease.

CPAP can look intimidating at first glance: a mask, a machine, tubes. Yet many older adults say that once they have adjusted over a few weeks, they feel:

• More alert in the daytime.
• Less likely to nod off in the chair.
• Less “foggy” in their thinking.
• More confident about their long-term heart and brain health.

It is OK if you are unsure at first. The goal is to try options with support, not to be forced into something you are frightened of.

Home environment: small changes that support easier breathing at night

While assessment and treatment decisions are made with professionals, there are gentle changes at home that may help:

• Sleep position. Some people snore less and breathe better on their side than on their back. You can experiment with pillow arrangements that make side lying more comfortable.
• Head elevation. Slightly raising the head end of the bed or using extra pillows (without bending the neck sharply) may ease snoring or mild breathlessness for some people, especially with heart or lung problems.
• Clear airways. Treat hay fever or nasal congestion with advice from your pharmacist or GP; avoid smoking indoors.
• Alcohol timing. Reducing alcohol, especially in the 3–4 hours before bed, can lessen snoring in some people.
• Safe layout. If you use oxygen, CPAP or tubing, make sure wires and hoses are placed so you will not trip when getting up to the toilet at night.

These steps do not replace proper assessment if there are worrying signs, but they can make the nights in between appointments a little easier.

Supporting someone else who snores or stops breathing

Partners and carers often feel stuck: worried about what they see or hear at night, but afraid of causing arguments. A few ideas:

• Choose a calm moment in the day, not the middle of the night, to talk about snoring or pauses.
• Use non-blaming language, for example: “I’ve noticed a few things in your sleep that worry me for your health. Can we talk about them?”
• Share specific examples: how loud the snoring is, the length of pauses, how often they happen.
• Focus on shared goals – staying independent, protecting the heart and brain, feeling more awake in the daytime.
• Offer practical support, such as going to the GP or sleep clinic together or helping with equipment.

It is normal for the person who snores to feel defensive at first. Gently keeping the focus on safety rather than blame can help.

Final reminder: This guide cannot diagnose sleep apnoea, decide whether you need CPAP or other treatments, or judge how risky your snoring is. It is educational support only. Please speak to your GP, practice nurse, respiratory or sleep clinic, or NHS 111 before making major changes to your sleep routine, medicines or equipment. Call 999 if you are worried about a life-threatening problem such as collapse, chest pain, sudden weakness, or stopped breathing.
