Sleep Apnea Symptoms: Night, Day, Women & Kids Checklist

The most common sleep apnea symptoms are loud snoring, pauses in breathing that someone else notices, and waking up gasping or choking [1][2]. During the day, the classic sign is feeling sleepy or worn out even after a full night in bed, often with morning headaches, a dry mouth or trouble focusing [1][2][3].

Many people never notice their own night-time symptoms. As NHLBI puts it, "You may not know you have these symptoms until someone tells you" [1].

This guide gives you a scannable checklist, explains how symptoms differ in women, men and children, and lists the signs people most often miss. It ends with free screeners and what to do next. It is general information, not a diagnosis. Only a sleep study can confirm sleep apnea [21].

Key takeaways

Three signs matter most together: loud snoring, breathing pauses someone else sees, and daytime sleepiness.
Women and children often look different: fatigue, insomnia, headaches and mood in women; hyperactivity and poor attention in kids, rather than obvious snoring or sleepiness.
A questionnaire can tell you whether to ask about a test. Only a sleep test can diagnose sleep apnea.

What are the signs of sleep apnea? A night vs day checklist

Sleep apnea symptoms fall into two groups: what happens while you sleep, and how you feel when you are awake. Tick the ones that apply to you, or ask a bed partner.

Checklist graphic with two columns: night-time signs (snoring, pauses, gasping, waking short of breath, restless sleep, night-time urination, night sweats) and daytime signs (sleepiness, dry mouth, morning headache, poor focus, low mood, low sex drive, high blood pressure) — Figure 1. A night and day checklist. Screenshot or print it and take it to your appointment.

Night-time symptoms (often noticed by someone else)

Loud or frequent snoring [1][5]
Breathing that stops and starts, or "silent pauses" [1][5]
Gasping, snorting or choking sounds [3][5]
Waking up short of breath or feeling like you are choking [4]
Waking up a lot, or restless sleep [3][4]
Getting up often to urinate (nocturia) [1][2]
Night sweats [4]

Daytime symptoms (symptoms of sleep apnea while awake)

Excessive daytime sleepiness or fatigue [1][2]
Waking with a dry mouth or sore throat [2]
Morning headaches [2][3]
Trouble focusing or memory problems [2][5]
Mood changes, irritability, depression or anxiety [2][4][5]
Lower sex drive or trouble keeping an erection [2][5]
High blood pressure, especially if it needs several medicines [2]

One or two items does not mean you have sleep apnea. Snoring alone is common, and "not everyone who snores has obstructive sleep apnea," according to Mayo Clinic [2]. The pattern matters more: snoring plus witnessed pauses plus daytime sleepiness is the combination that most deserves a conversation with a clinician.

What are the early signs of sleep apnea?

Early signs of sleep apnea are usually quiet. A partner mentions your snoring. You need more coffee than you used to. You wake with a headache or a dry mouth and do not know why.

Because these signs are easy to explain away, sleep apnea often goes undiagnosed for years. A classic Wisconsin study estimated that 82% of men and 93% of women with moderate to severe sleep apnea had never been clinically diagnosed [12].

Worldwide, researchers estimate that about 936 million adults aged 30 to 69 have at least mild obstructive sleep apnea [14]. Most of them are not being treated.

What are mild sleep apnea symptoms?

Mild sleep apnea generally means an AHI (apnea-hypopnea index) of 5 to under 15 breathing events per hour; 15 or more is moderate to severe [14]. Our guide to what AHI means explains how that number is measured.

Mild sleep apnea symptoms can look like the full list above, only fainter. Some people with a mild AHI feel very tired; others feel fine.

Sleep apnea symptoms in men

Men are more likely to have sleep apnea. In the Wisconsin Sleep Cohort, 24% of middle-aged men and 9% of women had an AHI of 5 or more [13].

The "textbook" presentation is also more common in men. NHLBI notes that frequent loud snoring is more common in men [1]. Men may also notice reduced libido or difficulty maintaining an erection [5].

Sleep apnea symptoms in women

Sleep apnea symptoms in women often look different. NHLBI lists fatigue, headache and insomnia as more common in women [1].

A 2021 review in the Yale Journal of Biology and Medicine found that women report snoring and witnessed apneas less often. Instead, they more often describe mood disturbance, lack of energy, daytime fatigue, morning headache, nightmares and insomnia [11].

Why are women under-diagnosed?

The same review gives three reasons women are missed: different presenting symptoms, differences in sleep study findings, and sociocultural factors [11]. It also notes that diagnostic criteria were largely built from studies of mostly male patients [11].

The gap is large. In the Wisconsin study, 93% of women with moderate to severe sleep apnea were undiagnosed, compared with 82% of men [12].

Menopause and sleep apnea

The risk of sleep apnea rises with menopause, according to the American Academy of Sleep Medicine [5]. The Yale review says prevalence "significantly increases following menopause" [11].

This creates a trap. Poor sleep, fatigue and mood changes in midlife are often blamed on menopause alone, which can delay a sleep apnea diagnosis [11]. If you are in perimenopause or past menopause and feel unrefreshed despite treatment for hot flashes or insomnia, ask whether a sleep study makes sense.

Sleep apnea symptoms in children and kids

Sleep apnea symptoms in children differ from adults. Sleepy adults slow down; sleepy children often speed up.

Night-time signs in children

Mayo Clinic lists these symptoms during a child's sleep [7]:

Snoring
Pauses in breathing
Restless sleep
Snorting, gasping, coughing or choking
Mouth breathing
Night sweating
Bed-wetting that starts after a long period of dry nights

Mayo also notes that young children may not snore at all and may instead show disrupted sleep [7].

Daytime signs in children

During the day, a child with sleep apnea might [7]:

Have morning headaches
Breathe through the mouth or have trouble breathing through the nose
Struggle with learning and attention, or do poorly in school
Act hyper, impulsive or aggressive
Gain weight poorly
Say they feel sleepy, or fall asleep on short car rides

NHLBI also notes that children with sleep apnea may be overactive and may have bedwetting [1].

Is it ADHD or sleep apnea?

Hyperactivity and poor attention can look like ADHD. Mayo Clinic describes these as behavior issues that are more common in children with sleep apnea than in adults; it does not say they are ADHD [7].

An American Academy of Pediatrics technical report found that treating childhood sleep apnea improved behavior and attention [9]. In the CHAT randomized trial, children who had their tonsils and adenoids removed had better behavior, quality of life and symptoms than those who waited. Formal attention and executive-function test scores, however, did not differ [10].

The takeaway: if your child has attention or behavior concerns and also snores, mention the snoring. The AAP recommends that all children and teens be screened for snoring [8]. Mayo Clinic advises seeing your child's healthcare professional for any symptoms, including frequent snoring [7].

For babies and toddlers, talk to your pediatrician directly about any breathing pauses, color changes or noisy, labored breathing during sleep.

Sleep apnea symptoms by group: a comparison table

Other clues	Low libido, erectile problems, nocturia [2][5]	Symptoms blamed on menopause [11]	New bedwetting, poor weight gain, school problems [7]

How are central sleep apnea symptoms different?

In obstructive sleep apnea, the airway collapses during sleep. In central sleep apnea, the brain briefly stops sending the signal to breathe. Central sleep apnea is less common than obstructive [6].

Three airway diagrams: an open airway, an obstructive apnea where the throat collapses while the breathing effort continues, and a central apnea where the airway is open but the brain sends no breathing signal — Figure 2. Open airway, obstructive apnea (the airway collapses) and central apnea (no breathing signal).

Symptoms overlap heavily. Mayo Clinic lists breathing pauses, sudden awakenings with shortness of breath, insomnia, excessive daytime sleepiness, trouble focusing, mood changes, morning headaches and snoring [6].

The main practical difference is snoring. With central sleep apnea, snoring "may not be as noticeable" as with obstructive sleep apnea [6]. So "I don't snore" does not rule out sleep apnea, especially if you wake up short of breath or cannot stay asleep.

If you already use CPAP, our guide to central vs obstructive apnea on CPAP explains how the two event types show up in your machine data.

Sleep apnea symptoms people miss

Getting up to urinate at night (nocturia)

Waking at night to pee is a listed symptom of sleep apnea [1][2]. A 2023 systematic review found that nocturia in people with sleep apnea increases along with sleep apnea severity [15].

Acid reflux and heartburn (GERD)

A 2023 meta-analysis of six studies and 2,950 patients found a significant association between sleep apnea and GERD (odds ratio 1.53) [17]. An association is not proof that one causes the other. But nightly reflux plus snoring is worth mentioning to your doctor.

Morning headaches

Morning headache is a recognized symptom of sleep apnea [2][3]. In one study of 1,131 people referred for a sleep study, 29% reported morning headaches [18].

Dry mouth or sore throat on waking

Waking with a dry mouth or sore throat is on Mayo Clinic's list of daytime symptoms [2]. It often goes along with mouth breathing and snoring.

When do sleep apnea symptoms mean see a doctor now?

Mayo Clinic advises seeing a healthcare professional if you, or your partner, notice any of these [2]:

Snoring loud enough to disturb your sleep or someone else's
Waking up gasping or choking
Pauses in your breathing during sleep
Excessive daytime drowsiness, including falling asleep while working, watching TV or driving

Drowsy driving is the red flag

If you have nodded off or nearly nodded off at the wheel, do not wait. Untreated sleep apnea is a significant contributor to motor vehicle crashes. A systematic review estimated the crash-rate ratio for people with obstructive sleep apnea at likely between 1.21 and 4.89 [20].

Stop driving when drowsy and book an appointment soon. In the UK, the NHS advises that once excessive sleepiness from sleep apnea is confirmed, you must not drive until symptoms like severe tiredness are under control [3].

Witnessed breathing pauses are the other big one. If someone has watched you stop breathing during sleep, that is a reason to ask for a sleep evaluation. Our article on whether sleep apnea is dangerous covers the long-term risks.

Free sleep apnea screeners to take next

Screening questionnaires can help you decide whether to raise sleep apnea with a clinician. They cannot diagnose it. The American Academy of Sleep Medicine strongly recommends against using questionnaires to diagnose sleep apnea without a sleep test [21].

Each of these takes a few minutes:

STOP-Bang questionnaire: eight yes/no questions covering snoring, tiredness, observed pauses, blood pressure, BMI, age, neck size and sex.
Epworth Sleepiness Scale: rates how likely you are to doze in eight everyday situations. It measures sleepiness, not sleep apnea itself.
NoSAS score: uses neck circumference, obesity, snoring, age and sex.
Berlin Questionnaire: groups questions about snoring, daytime sleepiness and blood pressure or BMI.

Take your results to your appointment. If your score suggests higher risk, the next step is usually a home sleep apnea test or an in-lab sleep study. Our sleep apnea test guide explains both options.

What happens to symptoms once sleep apnea is treated?

For many people, symptoms improve with consistent treatment. The American Academy of Sleep Medicine strongly recommends positive airway pressure (PAP) for adults with obstructive sleep apnea and excessive sleepiness [22].

Research has tracked specific symptoms:

Morning headaches: in one study of 116 adults on PAP for at least three months, the share with morning headache fell from 53.4% to 16.4% [19].
Night-time urination: a meta-analysis of five studies and 307 patients found CPAP significantly reduced nocturia episodes and urine volume [16].
Sleepiness: the same meta-analysis found a significant drop in Epworth Sleepiness Scale scores after CPAP [16].

Our sleep apnea treatment guide covers CPAP and the alternatives.

How to track whether treatment is working

The AASM says follow-up after starting PAP should include monitoring of objective efficacy and usage data [22]. In plain terms, two numbers matter most:

Usage: how many hours per night you actually wear the mask.
Residual AHI: how many breathing events per hour still happen while you are on therapy.

If your symptoms are not improving, those two numbers are the first place to look with your clinician. Our guide to what a good AHI on CPAP looks like explains the targets most clinicians use.

The Apnealytics dashboard showing usage hours and AHI for last night — Figure 3. Usage and AHI in Apnealytics: the two numbers to review with your clinician.

Apnealytics reads the SD card from ResMed machines (Philips DreamStation 1 and Fisher & Paykel SleepStyle are in testing) and charts your nightly usage and residual AHI side by side, so you can see whether better nights line up with fewer headaches or less daytime sleepiness. It is a tracking tool, not a diagnostic device. Any changes to your therapy or pressure should go through your clinician.

Frequently asked questions

What are the first signs of sleep apnea?

The first signs are usually loud snoring that a partner notices, waking up unrefreshed, and feeling sleepy during the day. Some people first notice morning headaches, a dry mouth on waking, or getting up at night to urinate. Because these are easy to explain away, many people live with them for years before anyone suggests a sleep study.

Can you have sleep apnea without snoring?

Yes. Snoring is common in obstructive sleep apnea, but not everyone snores. Women report snoring less often, young children may not snore at all, and snoring may be less noticeable with central sleep apnea. If you have daytime sleepiness, insomnia or wake up short of breath, ask about sleep apnea even without snoring.

What are the symptoms of sleep apnea while awake?

Daytime symptoms include excessive sleepiness or fatigue, morning headaches, a dry mouth or sore throat on waking, trouble concentrating, memory problems, irritability and mood changes. Some people also notice lower sex drive. Falling asleep while driving or at work is a serious warning sign that needs prompt medical attention.

How do sleep apnea symptoms differ in women?

Women are less likely to report loud snoring or witnessed pauses. They more often describe fatigue, insomnia, morning headaches, low energy, mood changes and nightmares. These overlap with depression and menopause symptoms, which is one reason women are under-diagnosed. Risk also rises after menopause.

What are sleep apnea symptoms in kids?

Children may snore, breathe through the mouth, sleep restlessly, sweat at night, or start wetting the bed after being dry. During the day they may seem hyperactive, impulsive or inattentive rather than sleepy, and they may struggle at school. If your child snores often, talk to their pediatrician.

Can a questionnaire tell me if I have sleep apnea?

No. Tools like STOP-Bang, the Epworth Sleepiness Scale, NoSAS and the Berlin Questionnaire estimate risk or sleepiness. They help you decide whether to talk to a clinician. The American Academy of Sleep Medicine recommends a home sleep apnea test or in-lab sleep study for diagnosis, not a questionnaire alone.

Do sleep apnea symptoms go away with CPAP?

Many improve. Studies show fewer morning headaches, fewer nighttime bathroom trips and lower daytime sleepiness scores after consistent PAP therapy. Results depend on wearing the mask most of the night and keeping residual AHI low. If symptoms persist on CPAP, review your usage and AHI data with your clinician.
