How Snoring Works and How it Affects Sleep Quality and Overall Health

Understanding why snoring happens, how it can affect your sleep, and how to deal with it can help lead to improved sleep and reduce tension between sleep partners.


Snoring is a common nighttime breathing issue—it affects about 25% of children, 40% of adult women, and 57% of adult men. Snoring can range from mild and occasional to chronic and severe. In most instances, snoring is simply irritating and disruptive for sleep partners and roommates. But, in some cases, it can be indicative of a more serious sleep disorder such as sleep apnea.

Why Do People Snore?

When sleeping, the muscles surrounding the airway in the back of the throat loosen, which narrows the airway. The relaxed tissue then flutters and vibrates with each breath, causing an audible snoring noise.

Some people are predisposed to snoring based on the size and shape of their jawbones, muscles, and tissue in the neck and throat. However, there are several other factors that can cause snoring, such as:

  • Being overweight or obese

  • Pregnancy

  • Crooked nasal septum

  • Nasal polyps

  • Nasal congestion

  • Swelling in the tonsils, adenoids, soft palate, and/or uvula

  • Large tongue relative to mouth size

  • Alcohol use

  • Sedative medication use

  • Poor muscle tone due to aging or other factors

  • Sleeping on your back

  • Mouth breathing/sleeping with the mouth open

Snoring Severity Levels

There are three main classifications for snoring severity levels:

Light snoring

Snoring lightly and occasionally is considered normal and typically doesn’t require any intervention. It is often most impactful for sleeping partners or those in close proximity who might have their sleep occasionally disrupted by the noise. Light snoring can often be alleviated relatively easily.

Primary snoring

Primary snoring happens more than three nights per week and is more disruptive than light snoring. While this type of frequent snoring can be more disruptive to sleep partners, it typically doesn’t disturb the sleep of the snorer themselves and isn’t considered a medical issue.

Obstructive sleep apnea-related snoring

OSA-related snoring can be very disruptive and detrimental to sleep quality and quantity for the snorer and any sleep partners, and can negatively affect overall health as well. 

It can be difficult to know if you snore if you sleep alone, unless you wake in the night with OSA symptoms like gasping or choking. If you aren’t sure whether you snore but you feel fatigued or have other symptoms of poor sleep, you may wish to set up a recording device in your sleeping space for a few nights.

How Snoring Affects Sleep and Overall Health

Light and primary snoring is generally benign and won’t affect your sleep or overall health. Again, the biggest impact will likely be on sleeping partners or roommates who experience sleep disruptions as a result of snoring noise. However, this can cause relationship tension and strife if the other person becomes chronically sleep deprived. They may suffer from daytime drowsiness, mood changes, trouble concentrating, and so forth.

However, OSA-related snoring can be much more serious. It can cause excessive daytime sleepiness, cardiovascular issues, high blood pressure, diabetes, stroke, depression, and cognitive impairment.

Getting enough quality sleep is crucial for our overall health, so excessive snoring or any other sleep disorder or disruption can have far-reaching effects.

Treatments to Help With Snoring

There are several different home remedies and types of treatment available to help alleviate snoring, including:

Maintain a healthy weight

Obesity and being overweight are leading contributors to snoring and can cause sleep apnea, so making lifestyle changes to achieve a healthy weight can significantly reduce snoring.

Minimize alcohol and sedative use

Alcohol and sedative medications can cause the muscles and tissues in the throat to relax more than normal during sleep, causing snoring. Limit use of these substances as much as possible (especially around bedtime) to help alleviate snoring.

Avoid sleeping on your back

Sleeping on your back can constrict your airway and allow your tongue to fall to the back of your throat, which often causes snoring. Sleeping on your side or stomach can help. It can be difficult to make this change if you are used to sleeping primarily on your back, but positioning yourself on your side with a pillow behind your back or sewing a tennis ball into the back of your sleep shirt can help train your body to sleep in other positions.

Elevate the head of your bed

Raising the head of your bed can reduce snoring as well, but it’s important to lift the entire mattress and not simply use more pillows as that can misalign your spine and lead to neck pain and other issues. Instead, use risers, wedge pillows, or an adjustable bed frame to lift the whole head of your bed. This can be particularly effective if you can’t sleep in any other position besides on your back.

Take steps to minimize nasal congestion

Congestion can be caused by allergies, dust, pet dander, and so forth, and in turn this can lead to increased snoring. Keep your sleeping space as clean as possible to minimize allergens, take allergy medication, or invest in breathing strips or internal nasal expanders to allow for easier breathing.

Use an anti-snoring mouthpiece

There are two main types of anti-snoring mouthpieces: mandibular advancement devices which hold the lower jaw forward, and tongue retaining devices which hold the tongue in place so it doesn’t fall back in the throat.

Build muscle tone

Mouth, tongue, and throat exercises can help strengthen muscles and reduce the chances of snoring. These exercises are most effective if they are completed daily for at least a couple of months.

All of the above treatments for snoring can be performed at home and don’t require a doctor’s intervention. However, if those prove ineffective, a doctor may prescribe the following: 

Use a CPAP, BiPAP, or APAP device

These devices pump air through a hose and a wearable sleep mask to assist with breathing while sleeping. They are meant to treat diagnosed sleep apnea and apnea-related snoring, and require a doctor’s prescription as well as personal calibration.


Surgery is generally a last resort to treat severe snoring or sleep apnea. A variety of surgeries can be performed depending on the exact cause of snoring. For example, someone might have a surgery to widen the airway, remove nasal polyps, correct a deviated septum, and so forth.

When to See a Doctor

If you haven’t noticed any particularly detrimental effects of your snoring, it’s not necessary to seek intervention and snoring can often be alleviated by taking steps on your own. However, if you notice any of these symptoms, it’s best to consult your doctor:

• Very loud, disruptive, or chronic snoring that can’t be relieved by the first 7 steps on the list above
• Snoring accompanied with snorting, choking, or gasping sounds or sensations
• Snoring brought on by recent weight gain
• Daytime drowsiness despite adequate sleep
• Difficulty concentrating or focusing
• Headaches and/or congestion in the morning that isn’t otherwise explainable
• High blood pressure
• Grinding your teeth in your sleep
• Needing to use the bathroom several times throughout the night

These symptoms can indicate sleep apnea or other sleep disorders and should be evaluated by your doctor to ensure that you get quality sleep and protect your overall health.
