The Best Sleeping Position for Back and Neck Pain

You hold one position for hours, and you are not awake to fix it. No position cures a back or a neck. What it changes is how much work your spine does overnight, which is often the difference between waking up sore and waking up fine. Here is what matters, position by position.

If you sleep on your back

Back sleeping is generally well tolerated. Your weight spreads across a wide surface and neither the neck nor the low back sits at the end of its range.

One change is worth making: put a pillow under your knees. With the legs flat, the muscles across the front of the hip pull the pelvis forward and the low back arches to follow, a small strain held for seven hours. Bending the knees lets the pelvis settle. A folded blanket works.

Under the head, use one pillow that fills the gap behind the neck without pushing your chin toward your chest. Two stacked pillows push the head too far forward.

If you sleep on your side

This is the most common position, and two things decide how it treats you.

A pillow between the knees. Without one, the top leg falls forward and down and drags the pelvis into a twist, so the low back spends the night rotated. Any firm pillow between the knees, running toward the ankles, keeps the top leg level with the hip.

Pillow height under the head. This is what decides how your neck feels in the morning. Your head sits out over the width of your shoulder, so the pillow has to fill the gap between your ear and the mattress. Too thin and the head drops toward the low shoulder. Too thick and it gets propped the other way. Either one bends the neck sideways for hours. Roughly right means your nose stays in line with your breastbone, and broad shoulders need more height than most pillows come with.

If you sleep on your stomach

This is the genuinely problematic one. Your face has to go somewhere, so the neck stays turned near the end of its rotation for hours, while the midsection sinks into the mattress and the low back is held in extension.

Plenty of lifelong stomach sleepers are not going to change, and saying it louder does not help, so here is the harm-reduction version. Use a very thin pillow under your head, or none, which keeps the neck from being cranked further back. Put a flat pillow under your pelvis and lower abdomen to take the sag out of the low back. Switch which way you turn your head from night to night. If you want off the position, the usual route is side sleeping with a long pillow to hug.

Pillows and mattresses, honestly

There is no single correct mattress. Studies comparing firmness do not crown a winner, and preference varies more than any rule does. A medium-firm surface suits most people because it holds the pelvis up without flattening the curve at the waist. A sagging one suits nobody: the hips drop into the dip and the low back holds a sidebend all night.

Pillow height matters more for neck pain than mattress choice does, and costs far less to correct. Filling material is preference. Height is mechanics. Replace a pillow that has gone flat. And do not fall asleep on a heating pad, for the reasons on ice or heat.

What a pillow will not fix

Give any change two weeks before judging it. If your trouble is mostly stiffness in the first half hour after you stand up, easing as you move, that is a separate complaint, covered on stiff back every morning.

The pattern that matters most is different. Positional pain eases when you shift. Pain that shows up only at night, or that reliably wakes you out of sleep, is a signal in its own right and belongs in the section below rather than in a bedding decision.

When you should see someone else

Call 911 or go to the nearest emergency room if back or neck pain comes with loss of bowel or bladder control, numbness in the saddle area (groin, inner thighs, or the area you sit on), or leg weakness that keeps getting worse.

See a physician promptly, rather than buying a new pillow, for:

• Pain that consistently wakes you from sleep, night after night
• Night pain that is unrelenting and does not change when you shift position
• Night pain with unexplained weight loss, fever, or night sweats
• Night pain with a history of cancer

Our page on when back pain is an emergency explains why those cannot wait.

Short of that, if you have changed position, sorted out pillow height, and given it a few weeks with no change, the problem is in the joints and tissue rather than the bedding.

Questions patients ask

What is the best sleeping position for lower back pain?

On your back with a pillow under your knees, or on your side with a pillow between your knees. Both keep the pelvis from being pulled out of a neutral position for hours. There is no single right answer for everyone, so start with whichever of those two you already find comfortable and add the pillow.

How should I sleep with neck pain?

On your back or your side, with pillow height doing the work. The pillow should fill the gap between your head and the mattress so the neck stays level with the rest of your spine, not propped up and not dropped down. On your side, that gap is as wide as your shoulder, so it usually takes more pillow than people expect.

Is sleeping on my stomach bad for my back?

It is the hardest position on the neck and the low back, because the neck stays turned for hours and the low back is held arched. If you are not going to give it up, use a very thin pillow or none under your head, put a flat pillow under your pelvis, and change which way you face from night to night.

What pillow should I use for neck pain?

One that fills the space between your head and the mattress in the position you actually sleep in. Height matters more than filling material or brand. Side sleepers with broad shoulders usually need a thicker pillow than a standard one, back sleepers need a thinner one, and any pillow that has gone flat is no longer doing its job.

Do I need a firmer mattress for back pain?

Not necessarily. Firmness preference varies from person to person and the research does not pick a winner, though a medium-firm surface suits most people. What clearly does not work is a mattress that sags in the middle, since your hips drop and your low back is bent sideways all night. Pillow height is usually the cheaper fix to try first.
