The main symptoms of obstructive sleep apnea are loud snoring, pauses in breathing, gasping or choking at night, and feeling very tired by day. The NHS lists breathing that stops and starts, gasping, snorting or choking noises, waking up a lot, loud snoring, and daytime tiredness (NHS). Many people do not notice their own symptoms, so a partner often spots them first. Symptoms can only point to sleep apnea. A sleep study confirms it. This guide explains what it sounds and feels like, how snoring differs, and signs in women and children. It is for education only.

Sleep Apnea Symptoms At Night
Cleveland Clinic lists these common symptoms (Cleveland Clinic):
- Waking up repeatedly in the night.
- Breathing pauses while you sleep, which a partner may notice.
- Unusual breathing patterns, such as breathing that gets deeper and shallower until it stops.
- Snoring.
- Waking up short of breath, or feeling like you are choking.
It also lists headaches, especially on waking, night sweats, mood changes and feeling restless at night as other symptoms (Cleveland Clinic). MedlinePlus says pauses in breathing may occur 30 times or more an hour (MedlinePlus). The NHS suggests asking someone to stay with you while you sleep, to check for symptoms (NHS).
What Does Sleep Apnea Sound Like?
MedlinePlus calls loud snoring a telltale symptom. It can be loud enough to hear through walls. The snoring is often followed by a silent pause, then a gasp or snort as breathing starts again (MedlinePlus). The NHS describes gasping, snorting or choking noises (NHS). So the pattern is loud snores, a quiet gap, then a sudden snort. A recording on your phone may help you show a doctor what is happening.
What Does Sleep Apnea Feel Like?
Most of the time you do not feel the pauses, because you are asleep. What you notice is the effect. You may wake up gasping or feeling short of breath, or wake with a headache. You may also feel restless at night, or hot and sweaty (Cleveland Clinic). By day, the NHS lists feeling very tired, trouble concentrating, mood swings and a headache on waking (NHS). NHLBI adds that untreated sleep apnea can cause trouble with concentration, decision-making, memory and self-control (NHLBI).
Daytime Symptoms And How Sleepy You Are
MedlinePlus says people may doze off while working, reading, watching TV or driving (MedlinePlus). If this sounds like you, avoid driving when drowsy and see a doctor. One simple tool is the Epworth Sleepiness Scale, an 8-question self-check on how likely you are to doze in everyday situations. Each item scores 0 to 3, for a total of 0 to 24. A score of 11 or more suggests a provider may look for an underlying cause (Cleveland Clinic). It is not a diagnostic test. Read sleep apnea screening tests for more, and signs of sleep deprivation if you are unsure whether it is lack of sleep.
Snoring vs Sleep Apnea: What Is The Difference?
Snoring is a sound from partly blocked airflow. Sleep apnea is repeated stops or lapses in breathing that disrupt sleep. Snoring can signal apnea, but many people snore without it (Sleep Foundation). The reverse also holds. Not everyone with obstructive sleep apnea snores. Studies cited by the Sleep Foundation suggest roughly one in five do not, and central sleep apnea often happens without snoring (Sleep Foundation). Gasping, choking or snorting during sleep is a warning sign, and pauses in breathing, especially with snoring, deserve medical attention (Sleep Foundation).
| Sign | Simple Snoring | Possible Sleep Apnea |
|---|---|---|
| Sound | Snoring that may be loud | Snoring with pauses, then a gasp or snort |
| Breathing | Continues | Stops and starts |
| Daytime | Usually rested | Tired, sleepy, trouble concentrating |
| Next step | Ask a doctor if it is new or loud | See a doctor and ask about a sleep test |
The table is a simple guide. The Sleep Foundation says sleep apnea cannot be diagnosed by symptoms alone (Sleep Foundation).
Signs Of Sleep Apnea In Women
NHLBI says symptoms may be different in women compared with men. Women may not have symptoms such as snoring, so they may not think they have the condition. Women more often report anxiety, daytime sleepiness, depression, morning headaches, insomnia, tiredness and frequent waking (NHLBI). Cleveland Clinic adds that sleep apnea is more likely to be diagnosed in men before age 50 (Cleveland Clinic). Many of these overlap with other problems, which can delay diagnosis. If you are often tired and wake often, ask about sleep apnea even if nobody has heard you snore.
Sleep Apnea Symptoms In Children
NHLBI lists night signs in children as snoring, mouth breathing, breathing that starts and stops, waking often and bedwetting. Daytime signs include being overactive or aggressive, trouble paying attention at school, a dry mouth or morning headaches, and sleepiness (NHLBI). Talk to your child’s doctor if you notice these.
How Severe Is Sleep Apnea?
Doctors use the apnea-hypopnea index (AHI), the average number of breathing events per hour. The NHS bands are mild at 5 to 14, moderate at 15 to 30 and severe over 30 (NHS). Symptoms alone do not tell you which band you are in. Only a test can. See how to read sleep study results and the AHI calculator.
How To Describe Your Symptoms To A Doctor
A little preparation makes the visit more useful. Ask someone who has seen your symptoms to come with you, as the NHS advises (NHS). Write down what they have noticed: loud snoring, pauses, gasping or choking. Note how you feel by day, such as how often you doze off and whether you wake with headaches. If you can, bring your Epworth score. Mention your health conditions and any medicines too. The more clearly you can describe the night and the day, the easier it is for a doctor to decide on the right test.
Do These Symptoms Mean You Have Sleep Apnea?
Not by themselves. Many of the symptoms also occur with other problems, such as short sleep, stress or other sleep disorders. MedlinePlus says a sleep study is the main way to confirm obstructive sleep apnea (MedlinePlus). But do not wait and hope. The NHS says sleep apnoea can be serious if it is not diagnosed and treated (NHS), and NHLBI notes it can affect concentration, memory and decision-making (NHLBI).
When To See A Doctor
The NHS says to see a GP if your breathing stops and starts in your sleep, you gasp, snort or choke, or you are always very tired in the day (NHS). NHLBI says to talk to your provider if someone tells you that you snore or gasp for air in your sleep (NHLBI). Cleveland Clinic lists heart attack signs, stroke signs and trouble getting enough air as reasons to seek emergency care (Cleveland Clinic). Next steps are a home sleep apnea test or a sleep study, and a visit to a sleep specialist. For causes, read sleep apnea causes and risk factors.
Quick Takeaways
- Loud snoring, pauses, gasping and daytime tiredness are the core signs.
- A partner often notices the pauses first.
- Not everyone who snores has sleep apnea, and not everyone with apnea snores.
- Women and children may show different signs.
- Only a sleep test confirms it, so see a doctor if you are worried.
FAQs About Sleep Apnea Symptoms
Can My Partner Tell If I Have Sleep Apnea?
They can spot clues, such as loud snoring, pauses and gasps. The NHS suggests having someone check your breathing while you sleep. A test is still needed to confirm it (NHS).
Does Sleep Apnea Cause Morning Headaches?
It can. The NHS and Cleveland Clinic both list headaches on waking among the symptoms (NHS, Cleveland Clinic).
Is Gasping In My Sleep Always Sleep Apnea?
No, but it is a warning sign. The Sleep Foundation says gasping, choking or snorting in sleep deserves attention, and that symptoms alone cannot diagnose sleep apnea (Sleep Foundation).
Can Sleep Apnea Cause Night Sweats?
Cleveland Clinic lists night sweats among other symptoms you might have (Cleveland Clinic). Night sweats have many causes, so mention them to your doctor.
How Do I Know If I Am Too Sleepy In The Day?
Try the Epworth Sleepiness Scale. A score of 11 or higher suggests asking a provider to look for a cause (Cleveland Clinic).
