The correct sleeping posture

Sleep on your back, it's the healthiest. That's the conventional wisdom — and it's only partly true. The truth is that there's no single correct sleeping posture, but there ARE postures that suit different bodies, different ages, and different conditions. Here's what physiotherapists actually recommend, plus a few small adjustments that can make any position more sustainable.

1. Sleeping on your back
2. Sleeping on your side
3. Sleeping on your stomach
4. The pillow makes the difference
5. What else affects your posture overnight

Sleeping on your back

Often called the ideal position because it keeps the spine in a natural alignment. It's particularly good for people with shoulder pain, lower back issues, or acid reflux (when slightly elevated). It's also kinder to your skin — no fabric pressing into your face for hours — and it can reduce wrinkles long-term.

The downside: it tends to make snoring worse, and people with sleep apnoea often find it the most problematic position. If you snore, try a small pillow under your knees to reduce lower back pressure and adjust slightly to one side.

Sleeping on your side

The most common position — and a good one for most people. The left side in particular is recommended for digestion and for pregnant women. Side sleeping reduces snoring, helps with sleep apnoea, and supports natural spinal alignment when done well.

The catch: it puts pressure on shoulders, hips, and the side of your face. A medium-firm pillow that fills the space between your ear and the mattress is essential. A pillow between your knees keeps your hips aligned. Both upgrades are small; both are noticeable.

Sleeping on your stomach

The honest answer: it's the least recommended position by physiotherapists. It twists the neck (you have to turn your head to one side for hours) and puts pressure on the lower back. If you really can't sleep any other way, use a very thin pillow or none at all, and place a small pillow under your hips to flatten the lower back curve.

The pillow makes the difference

Your pillow does more for your posture than the position you start in. The wrong pillow can make any position uncomfortable. The right pillow keeps your head, neck and spine in line:

• Back sleepers: medium height, supports the natural curve of the neck
• Side sleepers: firmer and taller, fills the gap between shoulder and ear
• Stomach sleepers: very thin, or skip it entirely

A bamboo pillow adapts well to most positions because the fill conforms to your shape, and the bamboo cover keeps the surface cool and breathable.

What else affects your posture overnight

The fabric you sleep on changes things more than people realise. A slippery, low-friction fabric like bamboo lets your body adjust naturally during the night without your skin sticking. That means fewer micro-awakenings, fewer twisted limbs, and less effort spent unconsciously fighting your bedding. Combined with a properly sized fitted sheet that doesn't pull or bunch, the smaller details start adding up.

Your spine spends 7–9 hours every night in whatever position you choose. The cumulative effect of getting it slightly right — or slightly wrong — is much bigger than any single night.
