The key to sleeping with upper back pain is keeping your spine aligned from your neck through your mid-back, then reducing the muscle tension that builds up during the day before you get into bed. Your sleeping position, pillow height, and mattress firmness all play a role, but so does what you do in the 20 minutes before you lie down. Here’s how to set yourself up for a less painful night.
Why Upper Back Pain Gets Worse at Night
Upper back pain has a long list of possible causes: muscle strains, poor posture from desk work or manual labor, osteoarthritis, herniated discs, or conditions affecting the ribs and shoulder blades where they anchor to the spine. For most people searching for sleep advice, the culprit is soft tissue strain or posture-related tension that accumulated during the day. When you lie down, your muscles finally stop working to hold you upright, but they don’t always release smoothly. A mattress that’s too soft or a pillow that’s the wrong height can hold your thoracic spine in a curved or twisted position for hours, turning mild daytime stiffness into genuine nighttime pain.
It’s worth noting that pain between the shoulder blades can occasionally be referred pain from internal organs, including the esophagus, heart, lungs, or kidneys. If your upper back pain came on suddenly, is sharp rather than achy, or is accompanied by chest tightness, difficulty breathing, or radiating pain down your arms or legs, that’s a different situation entirely and warrants immediate medical attention.
Best Sleeping Positions for Upper Back Pain
On Your Back
Sleeping on your back distributes your weight most evenly across the spine. Place a pillow under your knees to help your back muscles relax and maintain the natural curve of your spine. If you need extra support, a small rolled towel tucked under your waist can fill the gap between your body and the mattress. Your head pillow should keep your neck lined up with your chest and upper back, not propped forward or falling backward.
On Your Side
Side sleeping works well as long as you prevent your top shoulder from collapsing forward, which rounds the upper back and strains the muscles between your shoulder blades. Draw your knees up slightly toward your chest and place a firm pillow between your legs. This keeps your spine, pelvis, and hips aligned so one area doesn’t compensate for another. A full-length body pillow can serve double duty here: it keeps your legs separated and gives your top arm something to rest on, preventing that forward shoulder roll. Hugging a pillow or placing one under your top arm keeps the upper back open rather than compressed.
Avoid Stomach Sleeping
Lying on your stomach forces your neck into rotation and flattens the natural curves of your spine. For someone already dealing with upper back pain, this position almost always makes things worse. If you can’t break the habit entirely, placing a thin pillow under your pelvis and using no head pillow (or a very flat one) can reduce the strain somewhat.
Choosing the Right Pillow Height
Pillow height matters more than most people realize. The goal is to position your head and neck in the middle of your body’s center line, aligned with your mid-upper back and perpendicular to your shoulders. A pillow that’s too high pushes your head forward, stretching the muscles along your upper back. One that’s too low lets your head drop, compressing the same area from the opposite direction.
Research on pillow height has tested a range of options, and while there’s no single perfect number for everyone, a few patterns emerge. For back sleepers, studies have found that pillow heights around 7 to 10 centimeters (roughly 3 to 4 inches) tend to rate highest for comfort and cervical alignment. For side sleepers, the pillow needs to be taller to fill the gap between your ear and the mattress, with 10 centimeters being a common comfort benchmark. Body size matters too: one design study recommended side heights of about 14 centimeters for men and 12 centimeters for women, reflecting differences in shoulder width.
If you’re waking up with upper back pain and stiffness, your pillow is worth experimenting with before you replace your mattress. Try folding a towel to different thicknesses under your current pillow until you find a height that keeps your neck feeling neutral.
Mattress Firmness and Upper Back Support
A systematic review published in the Journal of Orthopaedics and Traumatology found that medium-firm mattresses consistently promoted better spinal alignment, sleep quality, and comfort compared to soft or extra-firm options. In one study, volunteers who switched from standard spring mattresses to medium-firm mattresses for 28 days reported improvements in back pain, shoulder pain, and spinal stiffness regardless of their age, weight, or BMI. A separate trial of 313 adults with chronic back pain confirmed the same pattern.
A mattress that’s too soft lets your hips and shoulders sink unevenly, pulling your upper spine out of alignment. One that’s too firm creates pressure points at your shoulder blades and doesn’t contour enough to support the curves of your back. Medium-firm hits the middle ground, offering enough give to cushion your shoulders while keeping your spine in a roughly straight line. If buying a new mattress isn’t an option, a medium-firm mattress topper (around 5 to 8 centimeters thick) can change the feel of your current setup significantly.
Stretches and Exercises Before Bed
Loosening the muscles around your upper back before you lie down can make a real difference in how you feel through the night. These take about 10 minutes and target the area between and around your shoulder blades.
- Shoulder rolls: Roll your shoulders up, back, down, and forward in a smooth circle. Repeat 2 to 4 times, then reverse direction. This warms up the muscles surrounding your upper spine without straining them.
- Rhomboid stretch: Sit or stand tall. Clasp your hands in front of you at about shoulder height, drop your chin toward your chest, and reach forward until you feel your upper back rounding and your shoulder blades pulling apart. Hold for 15 to 30 seconds. Repeat 2 to 4 times.
- Wall push-ups: Stand about 30 to 60 centimeters (12 to 24 inches) from a wall. Place your hands at shoulder height, slightly wider than your shoulders, fingers turned slightly outward. Slowly bend your elbows to bring your face toward the wall, keeping your shoulders and hips aligned, then push back. Do 8 to 12 reps. This gently strengthens the muscles that support your shoulder blades.
- Resistance band rows: Sit or stand facing a fixed resistance band. Hold one end in each hand with your arms extended and some tension on the band. Pull your elbows back along your waist, squeezing your shoulder blades together, then slowly return. This activates the muscles that tend to weaken from forward-leaning postures.
Move into the stretch only until you feel a gentle pull. Stretching through sharp pain is counterproductive and can increase inflammation.
Breathing to Release Upper Back Tension
Diaphragmatic breathing specifically helps relax the muscles of the upper back and rib cage because it shifts the work of breathing away from the small muscles between your ribs and around your neck. When you’re stressed or in pain, you tend to breathe shallowly into your upper chest, which keeps those muscles contracted for hours.
To practice once you’re in bed: lie on your back with your knees bent. Place one hand on your upper chest and the other just below your rib cage. Breathe in slowly through your nose, directing the breath so your belly rises and the hand on your chest stays still. Exhale through pursed lips, letting your stomach fall. The contrast between a rising belly and a quiet chest is the signal that your diaphragm is doing the work. Five minutes of this before sleep can noticeably reduce the tightness across your upper back.
Daytime Habits That Affect Nighttime Pain
What you do during the day directly shapes how your upper back feels at night. Hours of sitting with rounded shoulders, a forward head position, or a screen below eye level all overstretch the muscles along your upper back while shortening the muscles in your chest. By bedtime, those overstretched muscles are fatigued and inflamed.
A few adjustments during the day can reduce the load your upper back carries into the night. Position your monitor or laptop so the top of the screen sits at eye level. If you work at a desk, set a timer to stand and move every 30 to 45 minutes. When standing, think about pulling your shoulder blades gently down and back rather than letting them drift forward. These aren’t dramatic changes, but they reduce the cumulative strain that makes upper back pain worse once you finally lie down.
Repetitive strain from work or hobbies is one of the most common drivers of upper back pain, affecting both blue-collar and white-collar workers. If your pain consistently appears after specific activities, like overhead lifting, long drives, or extended typing sessions, addressing the ergonomics of that activity will do more for your sleep than any pillow swap alone.
