Snoring, a common nighttime nuisance, affects millions of people worldwide¹. Characterized by a harsh, often disruptive sound during sleep, snoring occurs when airflow through the nose and throat obstructs. This obstruction causes the tissues in the throat to vibrate, producing the characteristic snoring sound. Snoring happens when air flows past relaxed tissues in your throat as you breathe. These sagging tissues narrow your airway, causing the tissues to vibrate and produce the snoring sound1. While occasional snoring may be harmless, persistent and loud snoring can indicate underlying health issues and significantly impact sleep quality for the snorer and their bed partner, sometimes even creating tension in relationships².

Common Causes of Snoring

Several factors contribute to snoring, ranging from anatomical features to lifestyle choices. Understanding these causes is crucial for finding effective solutions⁴.

Mouth and Sinus Anatomy: The structure of your mouth and sinuses plays a significant role in snoring. A low, thick soft palate, an elongated uvula (the fleshy tissue hanging at the back of the throat), a small chin, a short neck, or enlarged tonsils and adenoids can narrow the airway, increasing the likelihood of snoring. Excess throat tissue in overweight individuals can further constrict the airway⁴.
Alcohol Consumption: Consuming alcohol, especially close to bedtime, relaxes throat muscles, reducing natural defenses against airway obstruction and promoting snoring⁴.
Nasal Problems: Chronic nasal congestion from allergies, a cold, a deviated septum, or nasal polyps can impede normal airflow, forcing mouth breathing and increasing the risk of snoring. A deviated septum, a misalignment in the wall that separates the two sides of the nose, can also restrict airflow and contribute to snoring⁴.
Sleep Deprivation: Inadequate sleep can lead to excessive relaxation of throat muscles, potentially exacerbating snoring⁴.
Sleep Position: Sleeping on your back often worsens snoring. Gravity’s effect on the throat narrows the airway, increasing the likelihood of tissue vibration. In fact, simply sleeping on your back can be a cause of snoring, as it allows the tongue to collapse to the back of the throat and restrict the airway⁴.
Age: As we age, muscle tone decreases, including in the throat, leading to a narrower airway and a higher risk of snoring².
Medications: Certain medications, such as sedatives and muscle relaxants, can relax throat muscles, similar to alcohol, increasing the risk of snoring².
Overall Health: Conditions like obesity, pregnancy, and hormonal changes can contribute to snoring. Obesity increases the amount of tissue in the neck and throat, while pregnancy and hormonal changes can cause swelling in the nasal passages².
Smoking: Smoking irritates and inflames throat tissues, leading to nasal congestion and airway obstruction, which can cause snoring⁵.

Types of Snoring

Snoring can be categorized into different types based on the source of the sound and the underlying causes⁹.

Nasal Snoring: This type of snoring originates from the nose and is often caused by blocked nasal passages due to a deviated septum, allergies, colds, or certain medications⁹.
Mouth Snoring: Mouth snoring occurs when someone breathes through their mouth instead of their nose during sleep. This can be caused by blocked nasal passages, enlarged tonsils, or weak palatal tissue⁹.
Tongue Snoring: When the tongue relaxes excessively during sleep, it can fall back and partially block the airway, leading to snoring. This is more common in people who consume alcohol or use sleep medication before bed, as well as those with excess fat around the neck¹¹.
Throat Snoring: This is often the loudest type of snoring and may be a sign of sleep apnea. However, it’s important to note that not everyone who snores loudly from their throat has sleep apnea. Throat snoring occurs when the muscles and tissues in the throat relax to the point of collapse, obstructing airflow to the lungs⁹.

Snoring Sounds and Patterns

Snoring sounds can vary significantly from person to person. Research has identified four types of energy sounds that contribute to snoring: ¹³

Type 1: Low-frequency single syllable sounds.
Type 2: Duplex sounds with low and middle frequencies.
Type 3: Duplex sounds with low and high frequencies.
Type 4: Triplex sounds with all three types of frequencies.

These sounds combine to create two different snoring waveform patterns: ¹³

Simple waveform snores: These occur when the airway remains open, and the snoring sound is produced by the vibration of the tissues.
Complex waveform snores: These occur when there is momentary closure of the airway, leading to more irregular and interrupted snoring sounds.

Complex waveform snores are more common in people with obstructive sleep apnea (OSA), as the airway repeatedly closes and reopens during sleep. However, both simple and complex waveforms can be present in OSA¹³.

Automated analysis of snoring sounds has been developed to help classify snoring patterns and identify potential sleep disorders. This analysis typically involves categorizing sleep sounds into three categories: snoring (“voiced non-silence”), breathing (“unvoiced non-silence”), and silence. These categories are then further analyzed based on four specific features to provide a more detailed understanding of the snoring pattern¹³.

Risk Factors for Snoring

While snoring can affect anyone, certain factors increase the likelihood of snoring. These include: ¹⁴

Being Male: Men are more likely to snore than women¹.
Being Overweight or Obese: Excess weight, especially around the neck and throat, increases the risk of snoring and obstructive sleep apnea¹.
Having a Narrow Airway: Anatomical factors such as a long soft palate, large tonsils or adenoids, a deviated septum, or chronic nasal congestion can narrow the airway and contribute to snoring. A high or narrow arched palate or a displaced jaw can also increase the risk of snoring¹.
Drinking Alcohol: Alcohol relaxes throat muscles, increasing the risk of snoring¹.
Family History: A family history of snoring or obstructive sleep apnea increases an individual’s likelihood of snoring¹.
Age: Snoring becomes more common with age due to decreased muscle tone².
Pregnancy: Hormonal changes and nasal congestion during pregnancy can increase the risk of snoring².
Endocrine Disorders: Certain endocrine disorders can affect the tissues in the airway and increase the risk of snoring⁸.
Genetic Syndromes: Some genetic syndromes are associated with anatomical abnormalities that can contribute to snoring⁸.

Health Consequences of Snoring

While occasional snoring may not pose significant health risks, chronic snoring, especially when associated with obstructive sleep apnea (OSA), can have serious consequences. It’s important to note that snoring can be a sign of sleep apnea even in those who don’t have typical sleep apnea symptoms².

Obstructive Sleep Apnea (OSA)

OSA is a serious sleep disorder in which breathing repeatedly stops and starts during sleep. Loud snoring is a common symptom of OSA, and the louder the snoring, the higher the likelihood of having sleep apnea¹⁵. During an apnea episode, the airway becomes completely blocked, leading to pauses in breathing that can last for several seconds. These episodes can occur hundreds of times a night, disrupting sleep and depriving the body of oxygen¹⁵.

It’s important to distinguish between snoring and sleep apnea. While snoring is a common symptom of OSA, not everyone who snores has OSA. In OSA, breathing stops or slows for more than 10 seconds at a time at various points during sleep. This causes drops in blood oxygen levels, brief and partial awakenings, fragmented sleep, and daytime sleepiness, making OSA a serious sleep disorder¹⁷.

There are two main types of sleep apnea: ¹⁸

Obstructive sleep apnea (OSA): This is the more common form, where the airway is blocked by relaxed throat muscles.
Central sleep apnea (CSA): This occurs when the brain doesn’t send proper signals to the muscles that control breathing.

In addition to snoring, other symptoms of sleep apnea include: ¹⁸

Gasping for air during sleep
Awakening with a dry mouth
Morning headache
Difficulty staying asleep (insomnia)
Excessive daytime sleepiness (hypersomnia)
Difficulty paying attention while awake
Irritability

Other Health Risks

OSA is linked to an increased risk of high blood pressure, heart disease, stroke, and other cardiovascular problems. The repeated drops in blood oxygen levels and surges in heart rate during apnea episodes put a strain on the cardiovascular system¹. Snoring may also increase high blood pressure even without the presence of sleep apnea²⁰.

Chronic snoring and OSA have also been associated with an increased risk of:

Type 2 diabetes ²
Depression ²⁰
Memory problems ²⁰
Cognitive decline ²⁰
Sudden cardiac death ⁶
Upper airway resistance syndrome (UARS) ²¹

UARS is similar to OSA but involves less severe airway obstruction. It can still cause significant sleep disruption and daytime fatigue.

Getting regular sleep is essential for our physical and mental health. Inadequate or poor sleep may make us prone to obesity and cardiovascular disease. Sleep is also important for well-being, stress management, and resilience⁶.

If you suspect you might have sleep apnea, it’s crucial to consult a healthcare professional. Many people with sleep apnea are unaware of their condition, and early diagnosis and treatment are essential to prevent serious health complications¹⁵. A sleep study may be needed to diagnose sleep apnea. Home sleep studies, where you sleep with a small monitor at home, are a common option for diagnosis²⁰.

Lifestyle Changes and Home Remedies to Reduce Snoring

Simple lifestyle changes and home remedies can often help reduce or eliminate snoring²².

Lose Weight: If you are overweight or obese, losing even a small amount of weight can significantly reduce snoring. Excess weight around the neck and throat compresses the airway, making snoring more likely²².
Avoid Alcohol Before Bed: Alcohol relaxes throat muscles, increasing the risk of snoring. Avoid alcohol for at least a few hours before bedtime²².
Treat Nasal Congestion: If nasal congestion is contributing to your snoring, use nasal strips, saline rinses, or over-the-counter decongestants to clear your nasal passages. You can also try clearing your nasal passages with decongestants or corticosteroid sprays, if approved by your doctor².
Avoid Sleep Deprivation: Get enough sleep. When you are sleep-deprived, your throat muscles are more likely to relax excessively, leading to snoring²².
Sleep on Your Side: Sleeping on your side helps prevent the tongue from falling back and obstructing the airway. Try using a pillow to support your back and prevent you from rolling onto your back during sleep. You can even sew a tennis ball into the back of your shirt to help you stay on your side²².
Elevate Your Head: Raising the head of your bed by a few inches can help improve airflow and reduce snoring²².
Practice Good Sleep Hygiene: Establish a regular sleep schedule, create a relaxing bedtime routine, and ensure your bedroom is dark, quiet, and cool to promote better sleep and reduce snoring²⁶.
Stay Hydrated: Drink plenty of fluids throughout the day. Healthy women should have about 11 cups of total water (from all drinks and food) a day; men need about 16 cups. Dehydration can make secretions in your nose and soft palate stickier, which can contribute to snoring²⁶.
Quit Smoking: Smoking irritates the throat and nasal passages, increasing the risk of snoring²³.
Mouth Exercises: Performing regular mouth exercises can help strengthen the muscles in your throat and tongue, reducing the likelihood of snoring. Some examples of mouth exercises include: ²³

Tongue slide: Slide your tongue backward along the roof of your mouth.
Tongue push-up: Push your tongue against the back of your upper teeth.
Tongue push-down: Push your tongue down against the back of your lower teeth.
Tongue stretch: Stick your tongue out as far as you can and hold it for a few seconds.

Anti-snoring pillows and backpacks: These can help keep you on your side and prevent you from rolling onto your back during sleep, which can reduce tongue snoring¹¹.
Sleep with your neck in a neutral position: Avoid extending or overly flexing your neck while you sleep to keep your airways open²⁴.
Over-the-counter (OTC) anti-snoring devices and snoring aids: These include mouth guards and nasal strips that can help keep your airways open²⁴.
Nasal dilator disks: These create back pressure in your airways, which may help keep them open and reduce snoring²¹.

Medical Treatments for Snoring

If lifestyle changes and home remedies are not effective, medical treatments may be necessary to address snoring, especially when it is associated with OSA²².

Oral Appliances: These devices, custom-fitted by a dentist, help keep the airway open by repositioning the jaw or tongue during sleep. A custom-fit oral appliance can improve your sleep, restore your alertness, and revitalize your health². If you and your doctor decide that oral appliance therapy is the best treatment option for you, your doctor will write a prescription and refer you to a qualified dentist²⁸. Possible side effects of oral appliances include excessive salivation, dry mouth, jaw pain, and facial discomfort²².
Continuous Positive Airway Pressure (CPAP): CPAP is the most common and effective treatment for OSA. It involves wearing a mask over the nose or mouth that delivers a continuous stream of pressurized air to keep the airway open⁷. Although CPAP is highly effective, some people find it uncomfortable or have trouble adjusting to the noise or feel of the machine²².
Surgery: In some cases, surgery may be an option to correct anatomical abnormalities that contribute to snoring, such as a deviated septum, enlarged tonsils, or excess tissue in the soft palate. Surgical procedures include septoplasty, tonsillectomy, adenoidectomy, and uvulopalatoplasty². Tonsillectomy and adenoidectomy, the removal of the tonsils and adenoids, were once common procedures for children with snoring, but today there are many alternative treatments available³⁰. Surgery may sometimes be combined with an oral appliance for better treatment outcomes³¹.
Injection Snoreplasty: This procedure involves injecting a substance into the soft palate to stiffen it and reduce snoring³⁰.
Pillar Procedure: This procedure involved implanting small polyester rods into the soft palate to stiffen it. However, due to manufacturing problems, the Pillar implants are no longer made³⁰.
Uvulopalatopharyngoplasty (UPPP): This is a traditional snoring surgery that involves removing the tonsils and reshaping the soft palate. It is performed in a hospital under general anesthesia and requires a longer recovery time than other procedures³⁰.
SNOREX by Dr. Mark Kayem: The SNOREX procedure, developed by Dr. Marc Kayem, is a minimally invasive in-office treatment for snoring. It involves using a special stitch at the back of the throat to tighten the soft palate and reduce snoring. This procedure takes approximately 20 minutes to perform and can provide long-lasting or permanent results³². SNOREX is similar to Injection Snoreplasty, stimulating collagen deposition and stiffening the soft palate. However, SNOREX offers a new approach in both the injection application and the suture³⁰.

Medications for Snoring

In addition to the medical treatments mentioned above, certain medications can be used to manage snoring, particularly when it is caused by allergies or nasal congestion: ⁷

Non-sedating antihistamines: These can help relieve allergy symptoms that contribute to snoring. Examples include cetirizine (Zyrtec), levocetirizine (Xyzal), and loratadine (Claritin).
Sedating antihistamines: These can also help with allergies but may cause drowsiness. An example is diphenhydramine (Benadryl).
Inhaled nasal corticosteroids: These can reduce inflammation in the nasal passages. Examples include fluticasone (Flonase) and triamcinolone (Nasacort).
Oral decongestants: These can help clear nasal congestion but should only be used briefly. Examples include pseudoephedrine (Sudafed) and phenylephrine (Sudafed PE).
Leukotriene modifiers: These can help control allergy symptoms and reduce inflammation. Examples include montelukast (Singulair) and zileuton (Zyflo).

Radiofrequency treatment in the office can also open the nasal airway and improve breathing at night²⁹.

It’s important to consult with a healthcare professional before using any of these medications to ensure they are appropriate for your specific situation.

Snore Guards vs. Oral Appliances

While both snore guards and oral appliances are designed to help reduce snoring, there are some key differences between them: ³³

Feature	Snore Guard	Oral Appliance
Use	Primarily for snoring	For snoring and obstructive sleep apnea (OSA)
Availability	Over-the-counter (no prescription needed)	Prescription required
Effectiveness	May be less effective for OSA	Generally more effective for OSA
Adjustability	Limited adjustability	Adjustable to ensure a proper fit
Lifespan	6 to 24 months	Longer lifespan
Cost	Less expensive	More expensive

Snore guards are typically simpler devices that aim to prevent the tongue from falling back and obstructing the airway. On the other hand, oral appliances are custom-fitted by a dentist and can be adjusted to reposition the jaw or tongue more precisely. This makes them more effective for treating OSA, as they can help keep the airway open throughout the night³³.

Choosing the Right Treatment

The choice of treatment for snoring depends on several factors, including the underlying cause, the severity of snoring, and individual preferences. Lifestyle changes are often the first line of treatment, while medical interventions like oral appliances, CPAP, or surgery may be necessary for more severe cases, especially those with OSA. It is essential to consult with a healthcare professional to determine the most appropriate treatment plan. The effectiveness of treatment depends on addressing the specific cause of snoring, so a thorough evaluation is crucial³.

Conclusion

Snoring is a widespread problem that affects millions of people worldwide. It can range from an occasional nuisance to a chronic condition with potentially serious health consequences. The causes of snoring are diverse, including anatomical factors, lifestyle choices, and underlying health conditions.

One of the most concerning consequences of snoring is its association with obstructive sleep apnea (OSA), a sleep disorder that can increase the risk of cardiovascular problems, diabetes, and other health issues. It’s crucial to recognize that snoring itself can be an early indicator of potential sleep apnea, even without other obvious symptoms.

Fortunately, there are many ways to address snoring and improve sleep quality. Lifestyle changes, such as losing weight, avoiding alcohol before bed, and sleeping on your side, can be highly effective. Home remedies, like nasal strips, mouth exercises, and maintaining good sleep hygiene, can also help. For more severe cases, especially those with OSA, medical treatments like oral appliances, CPAP therapy, and surgery are available.

If you experience persistent snoring, it is strongly recommended that you consult a healthcare professional to determine the underlying cause and discuss the most appropriate treatment options. Addressing snoring is essential not only for improving sleep quality but also for protecting your overall health and well-being.
