Why Do We Snore? Understanding the Causes of Snoring and How to Reduce It

You know the feeling when you're finally trying to fall asleep, and the person next to you suddenly starts snoring?

For some people, snoring happens occasionally, and for others, it can occur regularly and become disruptive to both their own sleep and that of their partner.

But what actually causes that uncomfortable sound?

The answer lies in what happens to the muscles and tissues around your airway when you fall asleep.

What Happens When We Snore?

When you fall asleep, the muscles in your throat and the tissues surrounding your airway naturally relax. This is a normal part of the transition from wakefulness to sleep.

However, as these muscles relax, the upper airway can become narrower. When you breathe through this narrowed passage, the movement of air can cause the relaxed tissues in the throat to vibrate.

That vibration is what produces the sound of snoring.

The soft palate, tongue, and other tissues around the upper airway can all contribute to this vibration. The more restricted the airway becomes, the greater the airflow disturbance can be, which may result in louder or more frequent snoring.

Why Do Some People Snore More Than Others?

Snoring does not have a single cause. Several factors can affect how narrow the airway becomes during sleep and how easily the surrounding tissues vibrate.

Sleeping Position

Your sleeping position can have a significant effect on snoring.

When you sleep on your back, gravity can cause the tongue and soft tissues at the back of the throat to move towards the airway. This can make the passage narrower and increase the likelihood of snoring.

Sleeping on your side can help keep the airway more open for some people, which is why changing sleep position is often recommended as a simple way to reduce snoring.

Nasal Congestion

A blocked or congested nose can also contribute to snoring.

When nasal passages are restricted because of a cold, allergies or other causes of congestion, breathing through the nose becomes more difficult. This can lead to increased mouth breathing during sleep and may contribute to snoring.

Addressing the underlying cause of nasal congestion can therefore help improve airflow during sleep.

Alcohol Before Bedtime

Alcohol can cause the muscles in the throat to relax more than they normally would during sleep.

This additional relaxation can contribute to narrowing of the airway and increase the likelihood or intensity of snoring.

For people who notice that snoring becomes more pronounced after drinking alcohol, avoiding it close to bedtime may help reduce the problem.

Lack of Sleep

Sleep deprivation can also play a role.

When you are significantly sleep-deprived, the muscles involved in maintaining the airway can become more relaxed during sleep. This may contribute to greater airway narrowing and make snoring more likely.

Maintaining a consistent sleep schedule and getting adequate sleep on a supportive mattress like Airboost can therefore be an important part of healthy sleep habits.

How Can You Reduce Snoring?

Since snoring can have several causes, there is no single solution that works for everyone. However, a few changes to your sleep habits and environment may help.

The Duroflex Wave Bed allows you to elevate your upper body to a 15-degree angle, providing an elevated sleeping position that may help improve airway positioning for some individuals.

However, it is important to remember that snoring can have different underlying causes, and changing your sleeping position may not address every case.

Is Snoring Always a Problem?

Occasional snoring is common and does not necessarily indicate an underlying health condition.

However, if you feel like you're prone to loud snoring, particularly when accompanied by other symptoms, it should not always be dismissed as a normal part of sleep.

In some cases, frequent snoring can be associated with obstructive sleep apnea (OSA), a sleep-related breathing disorder in which the airway repeatedly becomes narrowed or blocked during sleep.

Some signs that may warrant medical attention include:

- Pauses in breathing during sleep
- Gasping or choking during the night
- Excessive daytime sleepiness
- Waking up with headaches
- Difficulty concentrating during the day
- Waking up feeling unrefreshed despite getting enough time in bed

Not everyone who snores has sleep apnea. However, if snoring is persistent, disruptive or accompanied by these symptoms, it is advisable to speak with a healthcare professional.

Understanding Snoring Can Help You Sleep Better

Snoring begins with a simple process: as you fall asleep, the muscles around your airway relax. If the airway becomes sufficiently narrow, the tissues around it can vibrate as air passes through, creating the sound we recognise as snoring.

Factors such as sleeping position, nasal congestion, alcohol consumption and sleep deprivation can influence how frequently or loudly this happens.

For some people, simple changes, including sleeping on the side, keeping the nasal passages clear, avoiding alcohol close to bedtime and adjusting the upper-body position, may help reduce snoring.

But if snoring is persistent or accompanied by breathing interruptions and excessive daytime sleepiness, it is important to look beyond the sound itself and consider whether there may be an underlying sleep-related breathing disorder.
