Some adults snore more while lying on their back and less on their side. A comfortable positional change can be a useful measure, but the response varies and does not establish whether sleep apnea is present.

Why position can matter

The position of upper-airway tissues can influence airflow during sleep. This does not mean that sleeping on your back inevitably causes sleep apnea or that everyone can solve snoring by turning over.

Prioritise comfort and suitability

Try a comfortable side-sleeping position if it suits you. Avoid arrangements that cause pain or restrict breathing or movement. If you have a condition that affects positioning, ask a clinician for advice before using a positional device.

Understand the role of devices

Pillows and other positional products are intended to influence how you sleep. Check their instructions and intended use rather than assuming every anti-snoring label means the same thing. If sleep apnea has been diagnosed, discuss positional treatment within your prescribed care plan.

Review more than the sound

A partner’s report of less noise can be useful, but it cannot confirm normal breathing. Breathing pauses, gasping and significant daytime sleepiness need medical assessment. Seek advice if snoring continues to disturb sleep despite a comfortable positional change.
