What causes snoring?

If you or your partner snore, you are not alone. Snoring affects 30 million people in the UK. There are 10.4 million males and 4.5 million females who snore.

There are many different factors that can contribute to snoring, including structural abnormalities in the nose, mouth, or throat, being overweight or obese, the use of alcohol or sedatives, allergies, aging, sleep position, and smoking. Often snoring worsens with age, as more tissue develops, and muscles weaken.

Snoring is the sound that occurs when air flows past relaxed tissues in the throat, causing the tissues to vibrate as you breathe. Snoring can range from a mild, occasional sound to a loud, persistent noise that interferes with your sleep and the sleep of others.

The severity of your snoring can depend on the degree of relaxation in your throat muscles and the narrowness of your airway. Often illnesses such as a common cold can cause your snoring to worsen, as it can further restrict the airways.


What can make me more likely to snore?

Many factors can affect the severity of somebody’s snoring. They include:

  • Weight – Being overweight or clinically obese can increase the amount of soft tissue around the throat. This increases the pressure on the throat during sleep, causing it to narrow further. Typically, a person who is obese, and/or has a neck size above 17 inches, are more likely to snore. Often, they will snore more loudly and more frequently than somebody of average weight.
  • Smoking – Smoking causes inflammation in the airway, restricting the airflow and increasing the likelihood of snoring.
  • Alcohol – Alcohol relaxes the muscles and makes the tissue in your throat and mouth more prone to vibrations.
  • Allergies – Any allergy that results in rhinitis (runny nose) or sinusitis will cause the nasal passages to become inflamed. This restricts them, making snoring more likely.
  • Age – Often snoring worsens with age, as more tissue develops, and muscles weaken.
  • Pregnancy – The physical and hormonal changes in the body due to pregnancy can increase the likelihood of snoring.
  • Sleeping position – Sleeping on your back makes you more likely to snore or experience apnoea’s (breathing pauses).
  • Medications – Certain medications can relax your throat muscles, increasing your risk of snoring.
  • Genetics – Snoring is not inherited but certain genetics can contribute to the development of snoring. For example, the anatomy of your mouth or sinuses.

Is snoring worse in winter?

Yes the lack of humidity can result in you snoring. This is because the air is drier in the winter, which dries out your nasal passages and sinuses. During the winter months, you’re more prone to congestion, flu and colds, making you more likely to have a blocked nose, causing snoring. Using a humidifier can help reduce the risk of snoring as it provides moisture to the air and your sinuses.

Why do I snore so loud?

The more narrowed your airway, the stronger the airflow becomes. This increases tissue vibration, which causes your snoring to grow louder.

Why don’t I snore when I am awake?

When you are awake, the muscles in your throat are more active and tense, which can help keep your airway open. As a result, the air flows more smoothly through your throat when you are awake, and you are less likely to snore.

However, when you sleep, your muscles relax, which can cause your airway to narrow or become blocked. This results in snoring.

Why have I started snoring?

The development of snoring can be triggered by a change in weight, facial anatomy, allergies, higher consumption of alcohol and the development of smoking. 

Snoring and normal airway

What causes snoring in females?

Although, women snoring is less likely than men it is still common. Here’s a few reasons why women snore:

  • Menopause
  • Pregnancy
  • Hormonal imbalances
  • Weight gain

Menopause and snoring

As hormone levels drop during menopause, the risk of Sleep Apnoea increases. The hormonal changes can lead to weight gain and a redistribution of body fat, which can result in larger tissue around the neck increasing snoring or causing it. During menopause there can be a decreased level of estrogen and progesterone which can result in a reduction in the tone of the muscles in the upper airway. When muscle tone decreases, the airway may become narrower when laying down, making it harder to breathe.

How to stop snoring naturally

There are plenty of natural ways to reduce or stop snoring. Here are a few things you can try:

  1. Sleep on your side: Sleeping on your back can cause your tongue and soft palate to collapse to the back of your throat, leading to snoring. Try sleeping on your side to see if it helps reduce your snoring.
  2. Lose weight: Being overweight can contribute to snoring, so losing weight may help reduce or eliminate your snoring.
  3. Avoid alcohol, smoking and caffeine: Alcohol, smoking and caffeine are sedatives that relax the muscles in your throat, which can lead to snoring. Avoiding these substances or taking them only in moderation may help reduce your snoring.
  4. Treat allergies: Allergies can cause congestion in your nose and throat, leading to snoring. Try using over the counter or prescription allergy medications to treat your allergies and reduce snoring.
  5. Avoid sleeping on your stomach: Sleeping on your stomach can cause your neck to twist and your airway to become blocked, leading to snoring. Try sleeping on your back or side instead.
  6. Pillows and bedding: Special pillows and bedding designed to keep the head and neck in a proper position may help reduce snoring.


Does snoring indicate a health problem?

If these strategies do not help reduce your snoring, if your snoring is severe, or you experience choking in your sleep, you should seek further advice. In some cases, snoring may be a sign of a more serious underlying condition, such as Sleep Apnoea, which requires medical treatment.

Best anti-snoring devices UK

The effectiveness of anti-snoring devices can vary depending on the cause of the snoring and the individual using the device. Some people may find that certain devices work well for them, while others may not experience much improvement. Anti-snoring devices that are available, include:


  1. Mandibular Advancement Devices (MADs): These are mouthpieces that are worn at night and hold the lower jaw in a slightly forward position to help keep the airway open. Mandibular Advancement Devices can be used to treating snoring and mild Sleep Apnoea.
  2. Nasal strips: These are adhesive strips that are placed on the outside of the nose to help open the nostrils and improve airflow.
  3. Positional Sleep Therapy: A positional sleep therapy device is a great option for those who only snore when lying on their back. The Positional Sleep Therapy Trainer is worn each evening and vibrates when the wearer rolls over on to their back. The vibration encourages them to roll back over.
  4. Tongue Retaining Devices (TRDs): These are mouthpieces that hold the tongue in a forward position to help keep the airway open.
  5. Continuous Positive Airway Pressure (CPAP) machines: CPAP machines deliver a continuous flow of air through a mask or nasal plugs to help keep the airway open.
  6. Nasal irrigation: If you have nasal congestion, try using a saline nasal spray, a nasal irrigator or a humidifier to keep your nasal passages open and reduce snoring. The SinuPulse Elite Nasal Irrigator uses a natural saline solution to clear your sinuses and nasal passages in minutes.
  7. Humidification: Dry air can irritate the tissues in your throat and lead to snoring. Using a humidifier can help keep the air moist and reduce snoring. If you suffer from Sleep Apnoea and use a CPAP machine, a compatible humidifier can be added to your therapy depending on the device you use.

It’s important to note that not all anti-snoring devices are suitable for everyone.

Snoring and Sleep Apnoea

While snoring can be a minor annoyance for some people, it can also be a sign of a more serious underlying health condition, such as Sleep Apnoea.

Around 1 in 10 people who snore have Obstructive Sleep Apnoea (OSA). Being told that you snore may be embarrassing, but in most cases, snoring is harmless to the snorer and mostly an annoyance to the listener. However, if you experience any or all of these other symptoms, then it could be more serious:

  • Excessive sleepiness during the day
  • Lack of concentration
  • You have been told you choke or stop breathing during sleep
  • You have a BMI above 25
  • Have a recessed jaw or deviated septum
  • Need to urinate frequently at night

These problems are indicators that you or your partner might have Obstructive Sleep Apnoea. OSA is a sleep disorder, where a person’s airway regularly closes, and they stop breathing during sleep. These regular interruptions disrupt sleep, causing the person to wake up not feeling refreshed and often tired throughout the day.
