Does CPAP Therapy Stop Snoring?

February 14, 2018 | |

One of the side effects of sleep apnea can be snoring. While the main side effects – daytime tiredness and mental fogginess – affect only the patient, snoring can affect anyone else in the room where the person sleeps. If you want to know about CPAP and snoring and how to stop snoring, then read on.

Does CPAP Therapy Reduce or Eliminate Snoring?

It can do just that, in many cases, but since there are other causes for snoring, it is not fair to say that starting CPAP therapy will stop snoring. In a person with sleep apnea, the throat structures narrow and sometimes completely close during sleep creating a stoppage of air to the lungs. A CPAP machine uses continuous positive airway pressure to keep the throat more fully open throughout the night, preventing “apneic” events (breathing stoppages) that can usually reduce or eliminate snoring.

What is Snoring?

Snoring occurs when structures within the throat vibrate and cause noise. The sound can cover the range of noise levels, from quiet to incredibly loud. CPAP therapy can help with snoring, which may be a sign of obstructive sleep apnea (OSA). The parts of the throat that are most involved in snoring include the soft palate and the uvula.

Is Snoring Always a Symptom of Sleep Apnea?

While sleep apnea patients usually have snoring issues, many other people snore and do not have this condition.  Here are some of the reasons a person might snore:

  • The tongue dropping to the back of the mouth, which typically happens to people who sleep on the back.
  • A jaw that is misshapen or mis-positioned. This can be caused by muscle tension.
  • Nasal passageway obstructions.
  • Excess tissue or fat in the area of the throat.
  • Vibrations resulting from airway tissues touching.
  • Throat weakness, causing the throat to close during sleep.
  • Drugs or alcohol that have relaxed the muscles in the throat more than normal.

Snoring causes should be addressed to determine if sleep apnea is the primary cause and needs to be treated.

Is it Bad to Snore When You Sleep?

As many know, snoring can cause both the snorer and their bed partner to become sleep deprived, which can lead to irritable behavior, sleepiness during the day, lowered sex drive and thinking problems. Using a CPAP machine can often prevent these problems because it usually works to stop snoring.  Researchers also claim that snoring can result in social and psychological damage to those suffering from it. Moreover, there are studies that point to a possible link between snoring and a risk of stroke that’s about 67 percent greater than in non-snorers, and a heart attack risk about 34 percent greater than in the rest of the population. Because many sleep apnea patients snore, CPAP therapy can also usually solve this snoring problem.

Does CPAP Therapy Stop Snoring?

A new study reported by the American Academy of Sleep Medicine (AASM) suggests that 29.4 million Americans have OSA, but only 20 percent of them have been formally diagnosed.  Shockingly, that means 23.52 million Americans don’t realize they have OSA. They are all possibly snoring (and causing their bedroom partners to lose sleep as well) and certainly not as alert, productive or physically healthy as they could be.

Forty-five percent of normal adults snore occasionally and 25 percent snore every time they sleep. People most prone to habitual snoring are older and overweight. Children should never snore. In children, snoring may be a sign of problems with the tonsils and adenoids, and should be brought to a doctor’s attention.

In a recent poll of 430 CPAP users, we asked them whether their CPAP machines helped or worked to stop snoring. Almost 82% of them said that their snoring stopped with CPAP!


45 of our respondents (13.76%) were not sure whether their snoring decreased, and 3.6% (12 people) didn’t snore before they were given CPAP. Less than 1% (only 3 people) still snored after CPAP therapy! Obviously, CPAP still remains the most efficient and acceptable means to control snoring and OSA on the market today.

Snoring and Bed Partners

Of course, OSA sufferers aren’t the only ones impacted by the use of CPAP therapy. To confirm our suspicion, we asked the non-CPAP user about their experience. Interestingly, All but 1% (the CPAP users who still snore) have a better night’s sleep after their partners were put on CPAP. Maybe there are other sleep issues at play in these sleep partners related to their snoring, and that's also why we say that CPAP usually stops snoring.

Snoring Is Serious

Not only is snoring an affliction, it can be a sign of OSA which can lead to many long-term health problems. It has been shown that OSA can be quite dangerous including linked to heart attack, stroke, diabetes, not to mention chronic fatigue,daytime drowsiness and drowsy driving. Snoring can also causes disruption of the natural sleep cycle, leaving snorers and their bed partners sleepy during the day.

recent study conducted at Henry Ford Hospital in Detroit shows mounting evidence that people who snore are also much more likely to have thickening of their carotid artery, a condition called atherosclerosis. The thickening of these arteries can severely limit blood flow to the brain, weakening arterial walls and increasing the chances of an aneurysm or stroke.

Although there are a number of treatments that can alleviate mild snoring, sufferers should start by seeking medical diagnosis. A simple sleep study can easily determine if sleep apnea is present during sleep. Moreover, this will help determine if the case is mild or chronic, the possible causes as well as the most likely courses of treatment. Initial diagnosis will also help to show if further sleep studies are necessary to determine if the person is suffering from OSA.  What about the person who does not have OSA but snores? What can be done to stop snoring then?

What can be done for snoring – for the Occasional Snorer?

If you or your bed partner snore only occasionally, there are things that can be tried to quiet the vibrations. They include:

  • Loose weight and exercise the throat and tongue. We’ve written about the relationship between obesity, snoring and OSA in the past
  • Avoid things that relax the throat like sleeping pills and antihistamines before bedtime.
  • Don’t eat a heavy meal before bed
  • Avoid alcohol for at least four hours before bed
  • Sleep on your side rather than your back
  • Elevate the head of your bed four inches.

While snoring is often a sign of sleep apnea, the two are not mutually exclusive. Many people who snore do not have sleep apnea; likewise, many people who have sleep apnea do not snore. It’s important to keep an eye out for less obvious signals as well.
