The way you sleep can make snoring better or worse. When you lie on your back, gravity pulls your tongue and soft tissues toward the back of your throat, narrowing your airway and causing that familiar rumbling sound. Changing your sleep position is one of the simplest things you can try if you or your partner snores.
Not every position works for everyone, and sleep position alone won’t fix all types of snoring. But for many people, it can make a real difference. We’ve dug into the research and gathered practical advice to help you figure out which sleeping position might finally quiet the night.
Why Changing Sleep Position Can Reduce Snoring
Snoring happens when air can’t flow freely through your nose and throat during sleep. As you breathe, the relaxed tissues in your airway vibrate, producing that familiar rumbling sound. The narrower your airway becomes, the more forceful the airflow, and the louder the snoring.
What do sleep positions have to do with any of this? Quite a lot, actually.
When you lie on your back, gravity pulls your tongue and soft palate backward toward your throat. This naturally narrows the airway and increases the likelihood of those vibrations. It’s basic physics working against you while you sleep.
Changing positions can shift the way gravity affects your airway. When you sleep on your side, for example, your tongue and soft tissues are less likely to collapse backward. The airway is cleared, airflow meets less resistance, and snoring often decreases, or stops entirely.
Research supports this.
A study in the journal Sleep and Breathing found that over 56% of patients have position-dependent symptoms, and simply avoiding sleeping on the back can reduce snoring and breathing interruptions by at least 50%.
For people with mild to moderate positional snoring (meaning they snore primarily when lying on their back), this intervention can be remarkably effective without any other treatment.
Of course, not all snoring is purely positional. Factors like nasal congestion, alcohol consumption, obesity, and sleep apnea can contribute to snoring regardless of how you’re positioned. But for many people, adjusting their sleep position is a simple, and free, first step.
Common Sleep Positions
Not all sleep positions are created equal when it comes to snoring. Let’s break down the pros and cons of each major position and what the evidence tells us about their effects on nighttime breathing.
Side Sleeping
Side sleeping is widely considered the best sleep position to stop snoring, and there’s solid reasoning behind that reputation. When you lie on your side, your tongue and soft palate don’t fall backward into your throat the way they do when you’re on your back. The airway remains relatively unobstructed, allowing air to pass through with minimal turbulence.
The left side versus right side debate comes up frequently. While both sides are generally helpful for reducing snoring, sleeping on your left side may offer additional benefits for people with acid reflux or heartburn, conditions that can worsen snoring by irritating the throat. That said, either side works well for most snorers.
One challenge with side sleeping is staying in position throughout the night. Many people naturally roll onto their backs during sleep, which can bring the snoring right back.
Back Sleeping
If you’re a chronic snorer, sleeping on your back is likely making things worse. This position is often called the snorer’s trap for good reason.
When you lie supine (face-up), gravity causes your tongue and the fatty tissues at the back of your throat to slide backward. This narrows the airway significantly. The restricted space forces air through at higher velocity, which causes the surrounding soft tissues to vibrate more intensely.
For people with obstructive sleep apnea, back sleeping can be particularly problematic. The airway may collapse completely at times, causing breathing to stop temporarily, a much more serious issue than simple snoring.
If you’ve always been a back sleeper, this doesn’t mean you’re doomed to snore forever. But it does mean you’ll likely need to make a conscious effort to change positions, or find ways to reduce the negative effects of supine sleeping.
Elevated Sleeping
Elevating your head and upper body while sleeping can be a helpful compromise, especially if you can’t seem to stay off your back. By raising your head four to six inches, you change the angle at which gravity affects your airway.
This elevation helps prevent the tongue from falling as far backward and can reduce sinus congestion by promoting better drainage. Less congestion means less resistance in the nasal passages, which can translate to quieter breathing.
You can achieve this elevation in several ways:
- Wedge pillows: These specially designed pillows create a gradual incline from your hips to your head.
- Adjustable bed bases: Electric beds with automatic snoring detection, such as the Tempur-Ergo® Smart Base, utilize sensors to detect vibrations from snoring and automatically raise the head section by approximately 12 degrees to help clear airways.
- Extra pillows: A budget option, though stacking regular pillows can sometimes create awkward neck angles.
The key is finding an angle that’s comfortable enough to maintain throughout the night. Propping yourself up too steeply can cause neck pain or make it difficult to fall asleep in the first place.
Stomach Sleeping
Stomach sleeping is something of an outlier in the snoring conversation. On one hand, it can help keep your airway open because gravity pulls your tongue and soft tissues forward rather than backward. Some stomach sleepers report significant reductions in snoring.
On the other hand, this position comes with its own set of problems. Sleeping face-down typically requires turning your head to one side, which can strain your neck and spine. Over time, this can lead to chronic pain, stiffness, and misalignment issues that affect your overall sleep quality.
Stomach sleeping can also put pressure on your chest and lungs, potentially making breathing feel more labored. For these reasons, most sleep specialists don’t recommend it as a long-term solution for snoring.
If you already sleep on your stomach and don’t experience pain or discomfort, it may be working fine for you. But if you’re considering switching to stomach sleeping specifically to address snoring, side sleeping is generally a safer and more sustainable choice.
How To Transition To A Better Sleep Position
Knowing that side sleeping is the best sleep position to stop snoring is one thing. Actually training yourself to stay on your side all night? That’s another challenge entirely.
Our bodies have muscle memory, and we tend to return to familiar positions even while unconscious. If you’ve spent years sleeping on your back, your body will naturally drift back there during the night. Here are some practical strategies to help you make the switch.
The tennis ball technique is a classic approach. Sew a tennis ball (or a few) into the back of a snug-fitting sleep shirt. When you roll onto your back during the night, the discomfort will prompt you to shift back to your side without fully waking up. It sounds crude, but many people find it effective.
Body pillows can help you maintain a side position by providing something to drape your arm and leg over. This creates a stable, comfortable arrangement that feels more natural and makes rolling onto your back less likely.
Placing a pillow between your knees while side sleeping helps align your spine and hips, reducing strain on your lower back. This small adjustment makes side sleeping significantly more comfortable, especially if you’re used to sleeping on your back. Many people find this single change makes the biggest difference in how rested they feel in the morning.
Positional sleep aids are commercially available products designed specifically for this purpose. Some are wearable devices that vibrate gently when they detect you’ve rolled onto your back. Others are foam wedges or bumpers that physically prevent you from turning over.
Strategic pillow placement behind your back can create a barrier against rolling. Placing a firm pillow lengthwise along your spine provides resistance when you try to turn over.
Most people find that consistent effort for two to four weeks is enough to retrain their sleep habits. After that, side sleeping often becomes more natural, and the aids can be phased out.
Proper Head and Neck Positioning
Your sleep position isn’t just about whether you’re on your back, side, or stomach. How you position your head and neck matters significantly for both snoring reduction and overall comfort.
When side sleeping, your pillow height is crucial. If your pillow is too low, your head tilts downward, which can partially collapse the airway. If it’s too high, your neck bends upward at an unnatural angle, causing strain and potentially restricting airflow in a different way.
The goal is neutral alignment: your head, neck, and spine should form a relatively straight line. For most side sleepers, this means a pillow with medium to firm loft that fills the gap between your shoulder and your head without pushing your head upward.
Cervical pillows with contoured shapes are designed specifically to support proper neck alignment. They cradle your head in a depression while providing higher support under your neck. These can be particularly helpful for people who experience neck pain alongside snoring issues.
Avoid tucking your chin toward your chest, as this compresses the front of your airway. Similarly, extending your neck backward excessively can also cause problems. Think relaxed and neutral, not rigid, just properly supported.
When the Best Sleeping Position for Snoring Isn’t Enough
Position changes work wonders for many people, but they’re not a universal solution. If you’ve committed to side sleeping with proper head alignment and you’re still sawing logs every night, there may be other factors at play.
Several conditions can cause snoring regardless of position:
- Nasal congestion from allergies, colds, or structural issues like a deviated septum
- Excess weight, particularly around the neck, which puts pressure on the airway
- Alcohol consumption close to bedtime, which relaxes throat muscles excessively
- Sleep apnea, a more serious condition where the airway repeatedly collapses during sleep
If positional changes aren’t helping, it’s worth evaluating these other factors. Sometimes addressing allergies with antihistamines, losing weight, or cutting back on evening alcohol can make a significant difference.
Persistent, loud snoring, especially if accompanied by gasping, choking sounds, or excessive daytime sleepiness, deserves medical attention. These can be signs of obstructive sleep apnea, which requires proper diagnosis and treatment.
Best Devices and Techniques For Snoring
When changing positions isn’t doing the trick, several devices and techniques can help reduce snoring.
Nasal Strips and Dilators
These devices work by physically opening the nasal passages, reducing resistance to airflow. They’re inexpensive, non-invasive, and can be surprisingly effective for people whose snoring originates primarily from nasal congestion.
Mouth Taping
It involves placing specialized tape across your lips to encourage nasal breathing throughout the night. When you breathe through your nose instead of your mouth, you’re less likely to snore. Never use regular adhesive tape, only medical-grade tape designed for this purpose.
Start by testing it during daytime naps to ensure you’re comfortable before trying it overnight. This technique works best for people who can breathe freely through their nose and whose snoring is related to mouth breathing rather than structural airway issues.
Mandibular Advancement Devices (MADs)
Mandibular advancement devices are mouthpieces that hold your lower jaw slightly forward during sleep. This positioning helps keep the airway open and can significantly reduce snoring for many users. Over-the-counter options are available, though custom-fitted devices from a dentist tend to be more comfortable and effective.
Tongue-retaining Devices
Tongue-retaining devices hold the tongue forward to prevent it from falling back into the throat. They take some getting used to but can work well for people whose snoring is primarily caused by tongue-related airway obstruction.
Continuous Positive Airway Pressure Machine (CPAP)
Continuous Positive Airway Pressure Machines are the gold standard treatment for obstructive sleep apnea. They deliver a steady stream of air pressure through a mask, keeping the airway open throughout the night. While CPAP isn’t typically prescribed for simple snoring, it’s highly effective when sleep apnea is the underlying cause.
White Noise Machines and Humidifiers
White noise machines and humidifiers don’t stop snoring directly, but they can help. Humidifiers add moisture to dry air, which can reduce throat irritation and congestion. White noise can mask snoring sounds for bed partners, improving overall household sleep quality.
We’ve reviewed many of these products and sleep aids in depth. If you’re exploring your options, checking out our detailed reviews can help you make a well-informed choice before investing in any particular solution.
Finding the best sleep position to stop snoring is often the first and simplest step toward quieter nights. For many people, it’s all they need. For others, combining positional changes with other interventions creates a comprehensive approach that finally brings relief, for themselves and anyone else trying to sleep nearby.
