Positional Therapy for Snoring and Apnoea

Many people snore far more when they sleep on their back. If that sounds like you, simply changing position can make a real difference. Here is how positional therapy for snoring works, which aids help, and what the evidence actually says.

Why does sleeping on your back make snoring worse?

When you lie on your back, gravity pulls your tongue and soft palate backwards. That narrows the airway, so air moving through it speeds up and makes the relaxed tissues vibrate. The result is louder, more frequent snoring.

The research backs this up. In one study, the supine (back) position produced the most snoring and the highest sound intensity, while the lateral (side) position reduced both snoring time and loudness in non-apnoeic snorers. If your snoring is mainly a back-sleeping problem, it is sometimes called supine-dependent or positional snoring. The same pattern can apply to mild sleep apnoea, where back-sleeping makes the breathing interruptions more frequent.

Does positional therapy for snoring actually work?

For the right person, yes. UK guidance from NICE notes that positional therapy can help mild to moderate snoring and obstructive sleep apnoea, but it is not recommended for severe cases. Severe sleep apnoea needs clinical treatment, which a sleep clinic will guide. An app cannot diagnose any of this, and only a sleep study can grade severity, so persistent or worrying symptoms always belong with your GP.

The key word is positional. It only helps if your snoring is genuinely worse on your back. If you snore just as much on your side, moving position will not change much, and it is worth looking at other causes of snoring.

How do you stop sleeping on your back?

A few simple approaches, from cheapest to most deliberate:

Aid	How it works
Side-sleeping habit	Falling asleep on your side, supported by pillows
The tennis ball trick	A ball or bulky object sewn into the back of a sleep shirt, so rolling onto your back is uncomfortable
Positional pillows	Wedge or body pillows that hold you on your side
Vibrating positional devices	A small worn sensor that buzzes gently when you roll onto your back

There is no single best option. The cheap tricks work for plenty of people. A good anti-snore pillow can also help by keeping your head and neck aligned on your side.

How do you know if it is working?

This is where overnight data helps. The honest problem with any snoring change is that you are asleep, so you cannot judge it yourself. A few nights of tracking before you start, then a week or two after, shows whether your snoring loudness and frequency actually dropped. An app like Kip records and scores your snoring on your iPhone, with the audio staying on the device, so you can compare trends over time rather than relying on a partner’s tired guess. It is a wellness tool, not a diagnosis. For more, see the best sleeping position to stop snoring and how to track snoring.

FAQ

Is positional therapy enough on its own?

For mild, back-related snoring, it can be. For mild to moderate sleep apnoea, NICE says it can help, but it is not suitable for severe cases. If you have daytime sleepiness, gasping or breathing pauses, see your GP rather than relying on position alone.

How do I know if my snoring is positional?

Track a few nights and note your sleeping position, or use a snore app to compare loudness night to night. If you snore far more on your back than on your side, your snoring is likely positional and a good candidate for this approach.

Does the tennis ball trick really work?

For some people, yes. The idea is simple: make back-sleeping uncomfortable enough that you stay on your side. It is cheap to try. The main downside is comfort, and many people prefer a purpose-made positional pillow or device once they know position is the issue.
