When your back hurts, a good night's sleep can feel out of reach. You shift from side to side looking for comfort, then wake up stiff and tired. Small changes to how you lie in bed may help.
There's no single best sleeping position for back pain that works for everyone. The right one keeps your spine in a relaxed, neutral line and feels comfortable for your body. For most people, that means using pillows to support whichever position you already prefer rather than forcing a new one.
How sleep and back pain affect each other
Sleep and back pain work like a two-way street. Pain makes it harder to fall asleep and more likely you'll wake during the night. In turn, research suggests that short or broken sleep can make the nervous system more sensitive to pain, so the next day hurts more.
Breaking that cycle usually takes better support in bed, steadier sleep habits and care for the pain itself.
Finding the best sleeping position for back pain
If you sleep on your side
Side sleeping is comfortable for many people with back pain. Bend your knees slightly and place a pillow between your knees so your top leg doesn't pull your pelvis and lower back out of line. A full-length body pillow can help if you tend to roll forward.
If you have spinal stenosis, drawing your knees a little higher toward your chest may ease leg and back symptoms, because bending forward opens space in the spinal canal.
If you sleep on your back
Place a pillow under your knees to keep a gentle curve in your lower back and ease tension there. Some people also like a small rolled towel under the waist. Choose a head pillow that supports your neck without pushing your chin toward your chest.
If you sleep on your stomach
Stomach sleeping tends to arch the lower back and keep your head turned to one side for hours. If it's the only way you can fall asleep, place a thin pillow under your hips and lower belly, and use a flat pillow or none under your head.
Choosing pillows and a mattress
Your pillow should keep your head level with the rest of your spine. Side sleepers usually need a thicker pillow that fills the space between the ear and shoulder, while back sleepers need a thinner one.
A mattress should keep your spine level in your usual position without pressing hard on your shoulders and hips. Signs it may be time for a new one include visible sagging, waking up stiffer than when you went to bed, and sleeping better away from home.
Getting in and out of bed without strain
Sleeping with lower back pain often means the hardest moments come when you get up. A technique called the log roll keeps your spine steady:
- Bend your knees while lying on your back.
- Roll onto your side, moving your shoulders and hips together as one unit.
- Lower your legs over the edge of the bed while pushing up with your arms.
- Sit for a moment before you stand.
Reverse these steps to lie down.
Bedtime habits that help a sore back
- Keep a regular schedule. The CDC recommends at least seven hours of sleep a night for adults, with consistent bed and wake times.
- Warm up first. A warm shower or a few minutes of heat can relax tight muscles before bed.
- Stretch gently. Easy stretches, such as pulling one knee toward your chest, may help you settle.
- Wind down. Limit late-day caffeine and alcohol near bedtime, and set screens aside before sleep.
If pain keeps waking you, physical therapy can build a plan to calm the back and improve how you move.
When back pain at night needs a doctor
See a doctor promptly if:
- Pain is constant at night and doesn't change no matter how you lie
- You also have a fever, chills or unexplained weight loss
- You have a history of cancer or a weakened immune system
- Leg numbness, tingling or weakness is getting worse
Suddenly losing control of your bladder or bowels, numbness around the groin and buttocks, or weakness in both legs is an emergency: call 911. If loud snoring, gasping or daytime sleepiness leaves you unrested, ask your doctor about a sleep evaluation.
Frequently asked questions
Is it better to sleep on a firm mattress with back pain?
Not necessarily. Research suggests many people with back pain sleep better on a medium-firm mattress than on a very firm one, which can press on the shoulders and hips. A mattress that is too soft can let your hips sink and strain your lower back. Test a mattress in your usual position, and look for a trial period.
Why is my back pain worse in the morning?
Muscles and joints often stiffen after hours of lying still, and the discs in your spine take on fluid overnight. That stiffness usually eases within minutes of moving. If stiffness lasts more than 30 minutes, eases with exercise rather than rest, and your back pain began before age 45 and has lasted for months, tell your doctor, since that pattern can point to inflammatory back pain.
What is the best sleeping position for back pain during pregnancy?
Later in pregnancy, sleeping on your side is generally recommended. A pillow between your knees and another under your belly can ease strain on your lower back and hips, and a wedge pillow behind your back can keep you from rolling over. Ask your OB or midwife what's best for you, and read about our care for pregnancy-related back pain.
