What Causes
Snoring

Understanding the causes of snoring is the first step toward finding the right treatment and getting a good night's sleep.

Why Do People Snore?

Snoring occurs when the soft palate tissues at the back of the throat become elongated or lax, partially obstructing the airway during sleep. As air flows past these relaxed tissues, it causes vibration that produces the familiar snoring sound.

Several factors can contribute to or worsen snoring, including weight gain that leads to excess fat deposits around the neck, poor muscle tone in the throat and tongue, and the use of alcohol or sedatives before bed.

Snoring & Obstructive Sleep Apnea

Snoring is a highly common problem that afflicts many Americans. In fact, 90 million adults snore in the United States. While snoring frequently interferes with partners' ability to get a good night's sleep, it can also signal a serious sleep disorder that studies have shown can result in sudden death and increased risks of heart attacks.

Snoring is most frequently associated with obstructive sleep apnea (OSA), the single most common sleep-related breathing disorder. OSA is characterized by partial or complete obstruction of the upper airway while asleep.

The snoring associated with OSA is distinguished by being intermittent, broken up by gaps of silence followed by loud gasps. When the person suffering from OSA goes without breathing for too long, he or she will start gasping for air, disrupting sleep throughout the night.

Symptoms & Side Effects of OSA

The primary symptom of obstructive sleep apnea is excessive sleepiness and fatigue during the day. Due to repeated sleep disruption, individuals may fall asleep for very brief periods if they stop to sit or rest. In severe cases, they may even fall asleep briefly during conversations.

Reduced Concentration

Memory loss and difficulty focusing on everyday tasks

Pulmonary Hypertension

Increased blood pressure in the lungs from chronic oxygen deprivation

Reduced Executive Function

Impaired decision-making and problem-solving abilities

Mood Swings & Irritability

Frequent mood changes and reduced libido from poor sleep quality

Lifestyle Factors That Contribute to Snoring

Beyond anatomical factors, several lifestyle choices and demographic characteristics can significantly increase your risk of snoring and developing obstructive sleep apnea.

Treatment for Chronic Snoring

Chronic snoring is more than just a nighttime nuisance. Left untreated, snoring associated with obstructive sleep apnea can lead to serious health complications including increased risk of heart attacks, stroke, and sudden death. The repeated oxygen deprivation from OSA puts enormous strain on your cardiovascular system over time.

At TMJ & Sleep Therapy Centre of North Texas, Dr. Krish specializes in identifying the root causes of your snoring and developing personalized treatment plans. Whether through oral appliance therapy, myofunctional therapy, or other airway-focused treatments, we can help you breathe easier and sleep better.

Snoring Causes: Frequently Asked Questions

What causes snoring?

Snoring occurs when airflow becomes partially restricted during sleep, causing the soft tissues of the throat, soft palate, tongue, or airway to vibrate. The resulting vibration creates the sound commonly recognized as snoring. Several factors may contribute to airway narrowing, including anatomy, weight gain, nasal congestion, and sleep position.

Why do people snore?

People snore when the tissues in their upper airway relax during sleep and partially block normal airflow. As air moves through the narrowed airway, surrounding tissues vibrate and produce snoring sounds. Some people snore occasionally, while others experience chronic snoring that may be associated with an underlying sleep-related breathing disorder.

What are the most common reasons for snoring?

Common reasons for snoring include excess tissue around the airway, poor muscle tone in the throat and tongue, sleeping on your back, alcohol consumption before bed, nasal congestion, and obstructive sleep apnea. A professional evaluation can help determine which factors may be contributing to your symptoms.

What causes loud snoring?

Loud snoring often occurs when there is significant narrowing of the airway during sleep. The greater the airflow restriction, the stronger the tissue vibration may become. In some cases, loud snoring may be associated with obstructive sleep apnea and should be evaluated by a qualified healthcare professional.

Is snoring a sign of sleep apnea?

Not everyone who snores has sleep apnea, but snoring is one of the most common symptoms of obstructive sleep apnea (OSA). Warning signs that may indicate sleep apnea include loud snoring, gasping for air during sleep, pauses in breathing, excessive daytime fatigue, and morning headaches.

Can being overweight cause snoring?

Yes. Excess weight can contribute to snoring by increasing fatty tissue around the neck and upper airway, making it more likely that airflow will become restricted during sleep. Weight management may help reduce snoring in some individuals, depending on the underlying cause.

Does sleeping position affect snoring?

Yes. Sleeping on your back can increase the likelihood of snoring because gravity allows the tongue and soft tissues of the throat to move backward and narrow the airway. Some people notice improvements in snoring when sleeping on their side.

Can alcohol make snoring worse?

Alcohol can relax the muscles of the throat and airway, increasing the likelihood of airway collapse and tissue vibration during sleep. For this reason, drinking alcohol close to bedtime may worsen snoring and sleep-disordered breathing.

Does smoking contribute to snoring?

Smoking may contribute to snoring by irritating and inflaming the tissues of the upper airway. This inflammation can narrow the airway and increase airflow resistance during sleep, making snoring more likely.

Can chronic snoring affect your health?

Chronic snoring may affect sleep quality for both the individual and their bed partner. When snoring is related to obstructive sleep apnea, it may also be associated with increased risks of cardiovascular, metabolic, and quality-of-life concerns. A comprehensive evaluation can help identify whether an underlying sleep disorder is present.

How can I find out what is causing my snoring?

Determining the cause of snoring typically involves a comprehensive evaluation of the airway, sleep symptoms, medical history, and contributing risk factors. In some cases, a sleep study may be recommended to assess for obstructive sleep apnea or other sleep-related breathing disorders.
