What's more, there's a relationship between the severity of pain, overall mood, and the ability to function — and a good night of sleep can improve all these symptoms, at least temporarily, according to a study published in the November 2016 issue of the Annals of Behavioral Medicine.

Worst Sleep Positions for Back Pain

Some sleep positions can put added pressure on your neck, shoulders, hips, lower back, knees, and even your heels, all of which can lead to pain, Thomas says. There’s no one-size-fits-all sleep position to kick back pain, but you can try a few tricks to get it under control so that you can sleep more soundly.

The most common offender? Sleeping on your stomach. “Typically, sleeping on your stomach can flatten the natural curve of your spine, putting some additional strain on your back muscles,” Thomas says.

Plus, stomach sleeping means that your neck is rotated, which can actually result in neck pain or back pain between your shoulders, says Paul Grous, a physical therapist and spine specialist with Penn Therapy & Fitness in Woodbury Heights, New Jersey.

Don’t worry about keeping your body in the same position all night. It’s normal for you to move around a bit while you sleep, and that’s a good thing because a little movement can help ease pressure on your back. “Any sleeping position has the potential to amplify back pain if you maintain it for too long,” Thomas says.

Grous adds that the real culprit may not be sleep position but your daily activity — or a lack of it.

“My opinion of the biggest causative factor for back pain in our population is the amount of time we spend sitting during waking hours,” he says. “We sit too long and we don’t sit properly — we sit slouched with our backs rounded.”

During daylight hours, try to vary your posture as much as possible, and practice good posture when standing and sitting to help ease back pain at night.

Sleep Positions That Help Relieve Back Pain

First, you’ve got to be comfortable to get a good night’s sleep. Thomas suggests making a few simple modifications to your regular sleep position to help take a load off your back:

If you're a back sleeper: Put a pillow under your knees to allow your spine to maintain its natural curve.

Put a pillow under your knees to allow your spine to maintain its natural curve. If you're a stomach sleeper: Put a pillow under your lower abdomen and pelvis to ease back strain.

Put a pillow under your lower abdomen and pelvis to ease back strain. If you're a side sleeper: Draw your legs up slightly toward your chest and sleep with a pillow (a full body pillow can be comfortable) between your knees.

The Right Mattress and Pillow for Sleep

When it comes to selecting a mattress and pillow, Thomas says personal preference and comfort rule. Some people prefer the firmness of a harder mattress, while others are more comfortable on a soft mattress. He suggests spending a night in a hotel that offers options for guests to purchase pillows and mattresses so that you can try before you buy. Or, see if your mattress store lets you try out a bed overnight or even longer. “If that is not an option, perhaps sleeping on the floor in a sleeping bag may mimic a firm surface, and sleeping on a couch may mimic a softer surface,” Thomas says.

Grous says that some people may find it helpful to use a contoured pillow to alleviate neck strain or to sleep on just one pillow instead of a stack of several pillows.

If a few changes to your sleep position don’t help your back pain or sleep troubles, it may be time to get a medical opinion. If your pain worsens, Thomas recommends meeting with your doctor to check for any potentially serious problems.
