Is snoring dangerous?

Occasional mild snoring is usually benign. However, loud habitual snoring may indicate sleep-disordered breathing and should be assessed, particularly if accompanied by daytime sleepiness.

Can weight loss stop snoring?

In many individuals, weight optimisation can significantly reduce snoring by decreasing airway narrowing and collapsibility.

Do I need a sleep study for snoring?

If snoring is persistent, loud, or associated with symptoms such as fatigue or sleepiness, a sleep study can provide important diagnostic information.

Why am I tired even after sleeping 8 hours?

Sleep duration alone does not guarantee restorative sleep. Fragmented sleep, breathing disturbances, circadian misalignment, or nervous system activation can all reduce sleep quality. Even if sleeping sufficient hours there may be factors reducing the depth of sleep leaving you feeling insufficiently rested and restored.

Can sleep apnoea cause constant fatigue?

Yes. Obstructive sleep apnoea is one of the most common medical causes of persistent fatigue. Repeated breathing interruptions during sleep reduce oxygen levels and fragment sleep cycles, leaving individuals feeling exhausted during the day even after a full night in bed.

How do I know if my tiredness is a sleep disorder?

Persistent tiredness may indicate a sleep disorder if it occurs alongside symptoms such as loud snoring, breathing pauses during sleep, morning headaches, difficulty concentrating, or excessive daytime sleepiness. In these situations, a sleep study can help identify the underlying cause.

Can stress make you feel tired all the time?

Yes. Chronic stress activates the body's fight-or-flight response, which increases alertness hormones and prevents deep restorative sleep. Over time this can lead to persistent fatigue, poor concentration, and disrupted sleep patterns.

When should I see a sleep specialist for fatigue?

You should consider seeing a sleep specialist if tiredness persists for several weeks, affects daily functioning, occurs with snoring or breathing disturbances, or causes daytime sleepiness. A specialist assessment can determine whether a sleep disorder, circadian disruption, or lifestyle factor is affecting your sleep quality.

Should I get a sleep test?

If tiredness is ongoing, affecting daily functioning, or associated with symptoms such as snoring or excessive sleepiness, a sleep study can provide valuable diagnostic insight.

Is insomnia the same as not sleeping enough?

No. Insomnia involves difficulty sleeping despite having the opportunity to sleep, often due to heightened arousal or behavioural factors.

Can insomnia go away on its own?

Yes, particularly in acute cases. However, if symptoms persist, targeted intervention such as CBT-I is often required.

Do I need a sleep test for insomnia?

In most cases, insomnia is diagnosed clinically. A sleep study may be considered if another sleep disorder is suspected.

Is sleep apnoea serious?

Yes. While it is treatable, untreated sleep apnoea can increase the risk of cardiovascular disease, metabolic dysfunction, and accidents related to sleepiness.

Can you have sleep apnoea without snoring?

Yes, although snoring is common, some individuals may have OSA without prominent snoring.

Do I need a sleep test if I feel tired?

If tiredness is persistent and associated with symptoms such as snoring or sleepiness, a sleep study may be appropriate.

Which sleep test is best?

The best test depends on the symptoms being investigated. Many people only require a simple home sleep study, while more complex presentations may benefit from full polysomnography.

Can I do these tests at home?

Yes. All sleep studies offered by Grace Sleep are performed in the comfort of your own home.

Will I always need the most advanced sleep study?

No. Most patients can be accurately diagnosed using simpler investigations. More advanced testing is reserved for situations where additional information is needed.

How many time zones do I need to cross for this to be worth it?

Most people notice meaningful jet lag symptoms after crossing three or more time zones, particularly eastbound. For two time zones or fewer, the disruption is usually mild enough to manage without a formal protocol. From three time zones upwards — particularly for eastbound travel or when you need to perform immediately on arrival — a personalised protocol produces a measurable difference.

How far in advance do I need to book?

The earlier the better — the pre-travel component of the protocol typically begins three to five days before departure. For maximum benefit, contact us at least a week before your trip. That said, even a last-minute protocol delivered the day before departure is more effective than no preparation at all, particularly for the in-flight and post-arrival components.

Is melatonin available over the counter in the UK?

Melatonin is a prescription-only medicine in the UK. Your protocol will specify the timing and dosing at which melatonin would be beneficial — and we can advise on how to obtain it via a GP or private prescription. Over-the-counter alternatives and behavioural strategies are also included for those who do not have access to melatonin.

I travel internationally every week. Can this service work for ongoing schedules?

Yes. For cabin crew, frequent flyers, and athletes with complex rosters, we can design an ongoing circadian management strategy that accounts for your pattern of travel — not just individual trips. This is available as a bespoke programme. Contact us to discuss.

What if I am only at my destination for one or two days?

Short trips — two days or fewer — usually benefit from a different strategy: remaining on home time rather than attempting to adapt to the destination time zone. Your protocol will specify this where it applies. The goal is to keep you functional, not necessarily to fully adapt to local time.

Can this be combined with other Grace Sleep services?

Yes — jet lag management can be added to any Grace Sleep pathway or accessed independently. For patients managing insomnia or circadian rhythm disorders alongside frequent travel, the protocols are designed to be compatible and mutually reinforcing. Contact us to discuss how best to combine services for your situation.

Who is sleep optimisation for?

Sleep optimisation is for people who do not have a diagnosed sleep disorder but know their sleep could be better — those who wake unrefreshed, struggle with energy or focus, or feel their sleep is inconsistent or unrestorative. It is also suited to high-performers, athletes, and those with demanding schedules where sleep quality is a significant variable in their health and performance.

Is SleepImage different from a consumer sleep tracker?

Yes — significantly. SleepImage is a medical-grade, clinically validated device that measures physiological signals with diagnostic accuracy. Consumer trackers like Fitbit, Oura, or Apple Watch use movement and heart rate approximations to estimate sleep stages. SleepImage measures cardiopulmonary coupling — a validated clinical method for assessing sleep structure and quality. It is used in clinical research and healthcare settings, not designed as a wellness product.

How many sessions do I need?

The starter programme at £550 provides three sessions — appropriate for focused, specific sleep concerns or those wanting a defined starting point. The six-session core programme allows for a more thorough exploration and greater plan refinement. The twelve-session transformational programme is for those seeking profound, sustained change with longer-term specialist support. Your specialist will recommend the most appropriate programme at your initial consultation.

Are sessions in person or online?

All sessions are delivered via video consultation — available to anyone in the UK or internationally. The SleepImage device is shipped directly to you for the assessment period.

What is Grace Metabolic and how does it connect to sleep?

Grace Metabolic is our specialist metabolic health service — addressing nutrition, glucose regulation, body composition, and long-term metabolic wellbeing. Sleep and metabolic health are deeply interconnected: poor sleep impairs glucose regulation, increases appetite, elevates cortisol, and degrades body composition. Where relevant, we integrate metabolic insights into your sleep optimisation programme so both are addressed together rather than in isolation.

Who is sleep coaching for?

Sleep coaching is for people who want structured, practical support to improve their sleep without a clinical diagnosis or medical programme. It is well-suited to those whose sleep is affected by lifestyle, habits, stress, or environment — and who want gentle, sustained support to make meaningful changes. It is not designed for people with diagnosed sleep disorders such as insomnia disorder or obstructive sleep apnoea, for whom clinical pathways are more appropriate.

What is the difference between sleep coaching and sleep optimisation?

Sleep optimisation uses SleepImage medical-grade digital assessment to measure your sleep objectively across multiple nights before building a personalised plan. It is more data-driven and suited to those who want clinical-level insight into their sleep architecture. Sleep coaching is a behavioural and lifestyle programme — it does not include physiological assessment and focuses on practical habit change, routine building, and lifestyle factors.

How long does the programme take?

The programme consists of six sessions typically spaced one to two weeks apart, meaning the full programme runs over approximately eight to ten weeks. This spacing allows enough time between sessions to implement changes and observe their effect before your next check-in.

Are sessions in person or online?

All sessions are delivered via video consultation and are available to anyone in the UK or internationally. There is no geographic restriction.

What if I think I might have a sleep disorder?

If you suspect you have a clinical sleep disorder such as insomnia disorder or obstructive sleep apnoea, sleep coaching is not the appropriate starting point. Grace Sleep offers specialist clinical pathways for both conditions. Contact us and we will help direct you to the right service.

Can sleep coaching be combined with a Grace Metabolic programme?

Yes — and for many people, combining the two produces better outcomes than either alone. Sleep and metabolic health are deeply connected. If you are following a Grace Metabolic programme, your sleep coaching plan can be aligned with it so that your nutrition, movement, and metabolic goals are fully integrated with your sleep improvement strategies.

How do I know if my snoring is sleep apnoea?

The most common signs that snoring may indicate sleep apnoea are waking unrefreshed despite adequate sleep, excessive daytime sleepiness, a bed partner observing pauses in your breathing, morning headaches, and frequent night-time waking. A home sleep study is the only way to confirm or exclude a diagnosis. Many people are surprised to discover significant OSA with surprisingly few daytime symptoms.

Do I need a GP referral to book?

No. Grace Sleep is a private clinic and you can book directly without a GP referral. We do recommend informing your GP of any diagnosis so it can be recorded in your medical notes and factored into future care.

Is a home sleep study as accurate as a hospital study?

For diagnosing obstructive sleep apnoea, a Level 3 home sleep apnoea test is clinically validated and recommended by NICE and the British Sleep Society as the appropriate diagnostic tool in most cases. Full polysomnography — an in-laboratory Level 1 study — is reserved for cases with complex comorbidities, which we identify from your questionnaire and, where needed, from your consultant assessment.

What happens if I am diagnosed with sleep apnoea?

You receive a detailed written report from a GMC-registered sleep physician, including your AHI score, oxygen saturation data, and a personalised treatment plan. If CPAP is recommended, we initiate the full provision and support programme. If a mandibular device or other approach is more appropriate, we arrange this directly.

Can you treat snoring if I do not have sleep apnoea?

Yes. Primary snoring — snoring without sleep apnoea — is a real condition that disrupts sleep for both the snorer and their partner. Following a sleep study to exclude OSA, we can recommend appropriate management including positional therapy, weight management support, and, where indicated, referral to an ENT specialist.

I already have a CPAP machine but it is not working. Can you help?

Yes. Our CPAP Therapy Service includes a dedicated mask troubleshooting pathway for patients who already have a device but are struggling with comfort, leaks, pressure, or adherence. The most common reason people abandon CPAP is not the device — it is a poorly fitted mask. We assess your anatomy and provide a new one as part of the service.

How quickly will I have a result?

Equipment is typically dispatched within 24 hours of booking and pathway completion. Once the equipment is returned, results are reviewed within 48 hours. Most patients complete the full pathway — from booking to written results — within one week.

Do I need a referral to access CPAP therapy?

No. You can access the pathway directly. You do need an existing sleep study report or CPAP/BiPAP prescription — but you do not need a GP referral to upload one.

What if I already have a CPAP machine?

CPAP or Mask troubleshooting services are designed specifically for you. We will work with your device, unless you want to upgrade, and the data that you can provide us.

Do I need a referral for a sleep test?

No referral is required to arrange a private sleep test with us. You can book directly without going through your GP, though we always recommend informing your GP of any diagnosis so it can be recorded in your medical notes.

Is the sleep test uncomfortable?

No. The devices we use are lightweight and designed to be worn comfortably overnight without disturbing your normal sleep. Most patients report that the equipment has minimal impact on how they sleep.

How long does the sleep test take?

Most tests are completed over two nights of sleep. This allows us to capture night-to-night variation in your sleep patterns, which gives a far more reliable picture than a single night of monitoring alone.

Clinical-grade data.

Your own bed.

A sleep test — also called a sleep study — monitors your breathing, oxygen levels, heart rate, and sleep patterns while you sleep. It is the most effective and clinically established method for diagnosing common sleep conditions, including obstructive sleep apnoea, sleep-related breathing disorders, and unexplained daytime fatigue.

At Grace Sleep, our home sleep tests allow you to sleep naturally in your own bed while collecting clinical-grade data — without the disruption, cost, and inconvenience of an overnight hospital admission. The monitoring equipment is lightweight and straightforward to use.

The data it captures is reviewed by our specialist clinical team — including GMC-registered consultants — with results typically within 48 hours of completing your test.

If you are unsure which test is right for you, ask our team — a brief call is all it takes.

Signs you may

need a sleep test.

Many people live with disrupted sleep for years without realising the cause is identifiable and treatable. These are the symptoms that most commonly indicate it is time for a sleep test.

01

Loud or frequent snoring

Particularly snoring loud enough to disturb a partner, or that involves pauses in breathing — both are classic indicators worth investigating. A home sleep test can find out if the cause is sleep apnoea.

02

Waking gasping for air

Waking suddenly feeling breathless or gasping is a strong indicator of an obstructive breathing event during sleep and warrants urgent assessment.

03

Excessive daytime sleepiness

Feeling persistently sleepy despite adequate time in bed is one of the most common presenting symptoms of sleep apnoea. A sleep study can tell you why.

04

Morning headaches & poor concentration

Disrupted overnight oxygen levels frequently present as morning headaches. Fragmented sleep consistently impairs daytime focus and cognitive performance.

05

Restless sleep & limb movements

Unexplained twitching, kicking, or restlessness during sleep may indicate periodic limb movement disorder — detectable with our SMED multichannel study.

06

Sleep apnoea & driving

DVLA rules require drivers with known or suspected sleep apnoea to inform the DVLA and must not drive until adequately treated. A formal diagnosis is the first step.

Choose the test

that fits your symptoms.

We offer two home sleep studies — a first-line screening study and a comprehensive diagnostic study. Most people with straightforward snoring or suspected sleep apnoea start with the Pebble. The SMED is for when you need a fuller picture of how you sleep and why.

Conditions a sleep test can identify.

Sleep testing helps identify a range of disorders that share overlapping symptoms but require different management approaches. An accurate diagnosis is the foundation of effective treatment.

Obstructive sleep apnoea

The most common sleep-related breathing disorder — breathing repeatedly stops and starts during sleep. The most frequent reason patients are referred for testing. NHS guidance on sleep apnoea →

Periodic limb movement disorder

Repetitive limb movements during sleep that fragment rest — resulting in insufficient deep sleep, REM sleep, and unexplained daytime fatigue. Often undetected without proper testing.

Upper airway resistance syndrome

Breathing disruptions that reduce sleep quality without the obvious pauses seen in apnoea — often missed without the level of monitoring our SMED study provides.

Nocturnal oxygen desaturation

Drops in overnight oxygen levels — and sleep-related breathing disturbances generally — including subtle irregularities that affect restorative sleep quality.

Results are reviewed by our specialist clinical team — including Dr Rónan Astin, Dr James Brown, and Louise Berger. Not an automated algorithm. Every result is read by a clinician who understands the full clinical picture.
