Sleep Apnea vs Snoring: What Sets Them Apart

Your partner complains about your snoring, and you wonder whether it is just noise or something more. You can keep those days on paper: when someone heard you snore and how sleepy you felt. Or you log them in the symptom diary in Sam. Unlike paper, Sam also has your sleep duration and sleep stages from Apple Health, in the same app.

This guide explains what separates simple snoring from sleep apnea. It also covers sleep apnea without snoring and how it shows up in women. There is no self-test here, because none can tell the two apart. Only a test during sleep shows whether you have sleep apnea, and your doctor interprets it. How that test works and what to note beforehand is in Sleep Apnea: What to Log for Your Sleep Doctor. What Sam keeps for sleep apnea is on the sleep apnea page.

Is snoring always a sign of sleep apnea?

Not always. Snoring is the sound of throat tissue vibrating as air flows past, the American Academy of Sleep Medicine (AASM) explains. It is very common. About half of all people snore at some point in their lives. About 40 percent of adult men and 24 percent of adult women snore habitually.

InformedHealth.org is run by Germany's independent health institute IQWiG. It says snoring only counts as sleep apnea when breathing pauses come with it. In obstructive sleep apnea, the upper airway narrows or closes during sleep. InformedHealth.org says breathing regularly gets shallow or stops for more than ten seconds. The German sleep guideline follows the international classification of sleep disorders. There, snoring sits under "isolated symptoms and normal variants", not among the forms of sleep apnea.

The reverse also holds. InformedHealth.org says most people with obstructive sleep apnea snore very loudly. The AASM says snoring is more likely a sign of sleep apnea when silent pauses and choking or gasping follow. You cannot watch for that yourself while you sleep. That is why what others hear and see matters, and in the end the test.

When should you get snoring checked?

The NHS lists these reasons to see a GP or family doctor about snoring:

• you feel sleepy during the day
• your breathing stops and starts while you sleep
• you make gasping or choking noises while you sleep
• your snoring has a big impact on your life or your partner's
• lifestyle changes are not helping your snoring

The NHS says the doctor will look inside your mouth and nose and may arrange further tests. It helps to bring someone who can describe your snoring.

In these cases, do not wait for a later appointment. If you get drowsy or nod off while driving, pull over, stop driving and do not drive again until a doctor has looked into the sleepiness. Book that appointment now: InformedHealth.org notes that dozing off at the wheel is dangerous. The same applies if you are so sleepy during the day that you could nod off at the wheel. Repeatedly witnessed breathing pauses and sleepiness that limits your day are also reasons to see a doctor soon. If you are pregnant and snore, or someone has seen you stop breathing, tell your obstetrician or gynecologist. When snoring comes with breathing pauses, the German Sleep Society (DGSM) explicitly urges pregnant women to do so.

For sudden severe shortness of breath or chest pain, call your local emergency number (112 in the EU, 999 in the UK, 911 in the US). Do not wait for it to pass.

What makes snoring more likely?

According to the NHS, you are more likely to snore if you are overweight or smoke. Drinking too much alcohol and sleeping on your back also make it more likely. The AASM adds congestion from a cold or allergies. Snoring also becomes more common with age and tends to run in families. For hay fever, see Blocked Nose at Night: Poor Sleep with Hay Fever.

An obvious trigger is not an all-clear, though. The NHS links sleep apnea to obesity, alcohol, smoking, sleeping on your back and getting older too. InformedHealth.org notes that too much alcohol relaxes the throat muscles and can make sleep apnea worse. So if you snore after a drink, you may have both: a trigger for the snoring and sleep apnea.

Can you have sleep apnea without snoring?

Yes. Snoring is common in obstructive sleep apnea, but it is not always what stands out. There are several reasons:

• The AASM notes that in many cases people do not realize they snore. If you sleep alone, nobody hears it.
• Women report snoring less often, according to the DGSM. A review in the European Respiratory Review found that men snore more intensely.
• The AASM guideline cites an international classification. Under it, obstructive sleep apnea can be present without symptoms if the test counts enough breathing events.
• In central sleep apnea, the airway is not blocked. The AASM says the brain does not send the right signals to breathe.

Central sleep apnea is less common than the obstructive kind. The AASM says it usually stems from a problem in the brain or heart. Certain medications can cause it too. Its AASM symptom list does not include snoring. Instead it names disrupted sleep with frequent waking, trouble falling asleep and daytime sleepiness. Breathing pauses and waking up short of breath are on it too.

So no snoring is not an all-clear. Are you often very sleepy, do you wake up short of breath, or has someone seen you stop breathing? Then talk to your doctor. That holds even if nobody has heard you snore.

What do sleep apnea symptoms look like in women?

InformedHealth.org says obstructive sleep apnea is more common in men than in women. The DGSM calls snoring, breathing pauses and daytime sleepiness the classic signs. In women, other complaints often come first. The DGSM patient guide and the European Respiratory Review describe women with sleep apnea reporting these more often than men:

• trouble falling or staying asleep
• daytime fatigue and low energy
• morning headaches
• low mood, anxiety or other mood problems
• nightmares

The US National Heart, Lung, and Blood Institute (NHLBI) likewise lists fatigue, headache and insomnia as more common in women, and loud snoring as more common in men.

Women mention snoring and witnessed pauses less often. The DGSM suggests embarrassment as one reason. These signs are also mostly noticed by a bed partner, and many older women sleep alone.

The same complaints fit insomnia or depression. According to the DGSM, doctors may then not ask about breathing pauses and snoring. The DGSM says women are diagnosed up to 10 years later than men. So bring up snoring or witnessed pauses yourself when you talk about your sleep.

After menopause, the rate of obstructive sleep apnea in women doubles, independent of age and BMI, the review says. Its signs are then easily put down to menopause. If you keep a menopause symptom log, sleep problems and daytime sleepiness belong in it. Our menopause symptom diary shows what that can look like.

Snoring also increases during pregnancy, according to the DGSM. What to do if you are pregnant and snore is in the section on when not to wait.

Sleep apnea or insomnia: how do they connect?

InformedHealth.org says doctors call a sleep problem a disorder when it lasts more than a month. It has to mean more than three bad nights a week and reduce your quality of life. That is a description doctors use, not a test you can run on yourself. Shorter spells of poor sleep are still worth raising.

The two can go together. InformedHealth.org lists pauses in breathing at night as one possible cause of poor sleep. The AASM in turn counts insomnia among the common symptoms of sleep apnea. The DGSM reports a study of postmenopausal women who had trouble falling and staying asleep for more than six weeks. Over 60 percent of them had a breathing disorder during sleep. That is a result for that group, not a statement about you.

InformedHealth.org says a sleep study might be useful if breathing problems or leg movements may be disturbing your sleep. Which doctor to see for sleep problems, and how they check for sleep apnea there, is in What Doctor for Insomnia, and How Is It Diagnosed?. What Sam keeps for trouble falling and staying asleep is on the insomnia page.

Is there a reliable self-test for sleep apnea?

No, at least none that reliably separates snoring from sleep apnea. A doctor may use questionnaires, for example on daytime sleepiness. But the AASM found that questionnaires, clinical tools and scoring algorithms have low accuracy for this. It strongly recommends against establishing obstructive sleep apnea with them alone. A sleep test is needed: a lab study (polysomnography) or a home sleep apnea test with an adequate device. How to read the report of such a test is covered in AHI Sleep Study Results: How to Read Your Report.

So a reassuring questionnaire is no all-clear, and a worrying one is not a finding. A watch or an app does not replace the test either. What an Apple Watch sleep apnea notification means is covered in Apple Watch Sleep Apnea Notification: What to Do. Sam does not read that notification and does not show it.

How do you keep track of snoring and sleepiness?

In Sam, you log Snoring in the symptom diary as present, on the day someone told you about it. It has no severity and no time of day. Excessive daytime sleepiness you rate as mild, moderate or severe. Difficulty falling asleep and Waking during the night are present-only entries, like Snoring.

Sam records no sound, and the symptom diary has no note field. What your bed partner hears or sees, such as pauses or gasping, goes on paper with the date. If you sleep alone, note how you woke up and how sleepy the day was.

Sleep duration and sleep stages from Apple Health show as a trend in the same app. Those are your watch's readings, not a measurement of your breathing. Wellbeing Statistics shows on how many days of a period you logged symptoms and which came up most often. A full four-week example is in our guide to preparing for a sleep doctor.

Log snoring and sleepy days in Sam for your appointment

You go to the appointment with dated days, not guesses: when someone heard you snore and how sleepy you were.

• Instead of paper: in the symptom diary you log Snoring as present and sleepiness as mild, moderate or severe.
• Instead of guessing: Wellbeing Statistics counts your symptom days in a period and shows the most frequent ones.
• Instead of screenshots: sleep duration and stages from Apple Health show as a trend in the same app.
• Instead of a loose folder: doctor's letters and reports stay in the Health Vault.

Sam records no sound, counts no breathing pauses and cannot tell snoring from sleep apnea. More on the sleep apnea page.
