Up to 55% of people with chronic lower back pain report significant sleep disturbance, and the combination of lower back and hip pain can make finding a comfortable position feel impossible. The good news: a few changes to your sleeping position, pillow setup, mattress, and bedtime routine can meaningfully reduce nighttime pain and help you stay asleep longer.
Why Pain Gets Worse at Night
If your back and hips feel fine during the day but flare up at night, you’re not imagining it. Your body’s inflammatory signals follow a circadian rhythm. Pro-inflammatory molecules in your blood rise during nighttime hours and peak in the early morning, which is why joint stiffness and pain tend to be worst when you wake up. Lying still for hours also means your muscles cool down and stiffen, and sustained pressure on one area can irritate already-sensitive joints.
Understanding this pattern helps explain why the strategies below work: they reduce pressure on inflamed tissues, keep your spine aligned so muscles don’t have to compensate, and prevent you from staying locked in one position all night.
Best Sleeping Positions for Back and Hip Pain
Side Sleeping With a Knee Pillow
Side sleeping is the most popular position, but without support it can pull your top hip downward, rotating your pelvis and straining your lower back. Placing a firm pillow between your knees keeps your hips stacked and your pelvis level. This alone can dramatically reduce the pulling sensation across your lower back and the pressure on the hip you’re lying on. A full-length body pillow works too, with the added benefit of supporting your top arm so your shoulder doesn’t roll forward.
If one hip hurts more than the other, try sleeping on the opposite side. When both hips are painful, alternating sides throughout the night distributes the pressure.
Back Sleeping With Knee Support
Lying flat on your back can arch your lower spine and tighten your hip flexors, two things that make both back and hip pain worse. Placing a pillow under your knees bends them slightly, which flattens your lumbar curve against the mattress and takes tension off the hip joints. A rolled towel under the small of your back can add extra support if you still feel a gap between your spine and the bed.
Back sleeping spreads your weight across the largest surface area, so it creates the least pressure on any single point. If you can tolerate this position, it’s often the best starting point.
Stomach Sleeping (With Adjustments)
Stomach sleeping forces your lower back into extension and rotates your neck, which generally makes lower back pain worse. If you can’t fall asleep any other way, place a thin pillow under your pelvis and lower abdomen to prevent your back from sagging into a deep arch. Use a very flat pillow for your head, or none at all, to reduce neck strain. This isn’t ideal long-term, but it’s far better than stomach sleeping on a flat surface with no support.
Choosing the Right Mattress
A systematic review of mattress research found that medium-firm mattresses promote better comfort, sleep quality, and spinal alignment compared to both soft and very firm options. In one controlled study of 313 adults with chronic low back pain, those given medium-firm mattresses reported greater improvement in both pain and disability than those on firm mattresses. The old advice to sleep on the hardest surface you can tolerate is outdated.
What “medium-firm” means in practice depends on your body weight and sleeping position. Side sleepers generally need a slightly softer surface to cushion the shoulder and hip, while back sleepers benefit from something a bit firmer to prevent the pelvis from sinking. If your mattress is more than seven to ten years old and you wake up stiff every morning, replacing it is one of the highest-impact changes you can make.
For material, foam and hybrid mattresses (foam layers over a spring base) tend to offer the best pressure relief around the hips. Memory foam contours to your body and distributes weight away from painful joints. Pure innerspring mattresses can feel unforgiving at the hip, though models with a thick foam top layer bridge the gap. If you have hip bursitis or arthritis, prioritize pressure relief over firmness.
Stretches to Do Before Bed
A short stretching routine before you get into bed loosens the muscles around your hips and lower back, reducing the stiffness that builds overnight. Three stretches from the Hospital for Special Surgery are particularly effective for this area.
Cat-cow: Start on your hands and knees with your wrists under your shoulders and knees under your hips. Tighten your abs, squeeze your glutes, and tuck your tailbone to round your back like a cat. Hold for 10 seconds. Then let your lower back sag toward the floor while your tailbone rotates upward. Hold for 10 seconds. Repeat five to ten times. This gently mobilizes your entire spine and warms up the muscles along your lower back.
Child’s pose: From hands and knees, slowly lower your hips toward your heels while reaching your arms forward on the floor. Hold for 30 seconds, then return to the starting position. Repeat three times. The key is to focus on sitting back toward your heels rather than pressing your chest to the floor, which can actually strain your lower back instead of relieving it.
Lying knee to chest: Lie on your back with both legs extended. Pull one knee toward your chest with both hands clasped behind it. Hold for 30 seconds, then repeat three times before switching sides. This stretches the hip flexors and glutes while gently decompressing the lower spine. If you feel discomfort in your lower back, bend the opposite leg so your foot is flat on the floor to stabilize your pelvis.
The whole routine takes about ten minutes. Doing it consistently matters more than doing it perfectly.
Your Sleep Environment
Pain disrupts sleep, and poor sleep lowers your pain threshold the next day, creating a cycle that feeds on itself. Small changes to your bedroom can help break it. Keep the room between 60 and 67°F (15 to 19°C), which is the range that supports stable deep sleep. Above 70°F, your body has trouble cooling down enough to maintain restful sleep stages, and muscle tension tends to increase in overly warm rooms.
A dark, quiet room matters too, but temperature is especially relevant for pain. Cooler temperatures help your muscles relax, while warmth under the covers (a heating pad on low for 15 to 20 minutes before sleep, then removed) can soothe stiff joints as you’re falling asleep. The combination of a cool room and localized warmth on your back or hip gives you the benefits of both.
Signs Your Pain Needs Medical Attention
Most lower back and hip pain improves with the strategies above, but certain patterns signal something more serious. Pain that wakes you from sleep (not just makes it hard to fall asleep) or that only appears when you lie down can indicate an infection, fracture, severe nerve compression, or in rare cases a tumor. Loss of bladder or bowel control alongside back pain is a medical emergency called cauda equina syndrome, where nerves at the base of the spine are compressed and may need surgical decompression to prevent permanent damage. Unexplained weight loss paired with back pain, numbness or weakness spreading down both legs, or a fever that doesn’t respond to over-the-counter medication all warrant prompt evaluation.
For everyone else, the path forward is consistent adjustments: the right position, the right support, a brief stretching habit, and a sleep environment that works with your body instead of against it. Most people notice improvement within a few nights of making these changes, though it can take a couple of weeks to fully adapt to a new sleeping position.
