The Best Sleeping Positions for Back Pain, Snoring and Deep Sleep

Your sleeping position does more than determine which side of the bed you wake up on. It affects your spinal alignment, airway function, digestion, and the quality of sleep you achieve. Here is what sleep specialists and physiotherapists recommend for common concerns.

For Back Pain: On Your Back With Knee Support

Sleeping on your back distributes weight evenly across your widest surface area, minimising pressure points and maintaining the natural curve of your spine. Placing a pillow or rolled towel beneath your knees takes pressure off the lower back by reducing lumbar lordosis. If back sleeping feels uncomfortable initially, start by spending the first 15 minutes of bedtime in this position and gradually extend the duration. For those who cannot tolerate back sleeping, the side-lying position with a pillow between the knees is the next best option.

For Snoring and Sleep Apnoea: On Your Side

Snoring occurs when the airway partially collapses, and gravity makes this worse when you lie on your back. Side sleeping — particularly on the left side — keeps the airway more open and has been shown to reduce snoring frequency and severity significantly. If you tend to roll onto your back during sleep, the tennis ball technique works surprisingly well: attach a tennis ball to the back of your sleep shirt, making back sleeping uncomfortable enough that you naturally stay on your side. Specialised positional pillows can achieve the same effect more comfortably.

For Acid Reflux: Left Side, Elevated

The anatomy of the stomach means that left-side sleeping keeps the gastroesophageal junction above the level of stomach acid, reducing reflux episodes. Studies published in the American Journal of Gastroenterology found that left-side sleeping reduced acid reflux by up to 71% compared to right-side sleeping. Elevating the head of your bed by 15-20 centimetres — using bed risers rather than extra pillows, which can strain the neck — provides additional protection by using gravity to keep acid where it belongs.

For Neck Pain: Pillow Height Matters More Than Position

Regardless of your sleeping position, your pillow should maintain neutral cervical alignment — meaning your neck should be a natural extension of your spine rather than bent up, down, or to the side. Side sleepers generally need a thicker pillow to fill the gap between the shoulder and ear. Back sleepers need a thinner pillow that supports the natural cervical curve without pushing the head forward. Stomach sleeping is the most problematic for neck health, as it requires sustained rotation of the cervical spine.

Changing Your Sleep Position

If your current sleep position is contributing to pain or poor sleep quality, change is possible but requires patience. Most people take two to four weeks to adapt to a new position. Use pillows strategically to support the new position and prevent unconscious rolling. Body pillows are particularly effective for maintaining side-sleeping posture. Remember that you will naturally shift positions throughout the night — the goal is to spend the majority of your sleep time in an optimal position, not to remain rigidly in place all night.
