The Best Sleeping Positions for Back Pain: Lower Back Pain Relief

Finding a comfortable sleeping position when your low back pain flares up can feel like a nightly puzzle. You shift from side to side, try lying flat, curl up—yet nothing seems to fully relieve the discomfort. By morning, you may wake up feeling just as stiff, if not worse.

If this sounds familiar, you’re not alone. The way you sleep plays a significant role in how your back feels—both during the night and when you wake up.

Chronic sleep deprivation has been linked to an increased risk of developing chronic and disabling back pain, irrespective of daily activities.

Understanding the best sleeping positions for back pain isn’t about finding a perfect posture. It’s about supporting your body in a way that reduces strain, improves alignment, and allows your muscles to relax. Making small changes to your sleep positions can make a big difference in how your back feels.

• Spinal alignment: Keeping your head, shoulders, and hips in a neutral line
• Proper posture: Maintaining proper posture during sleep supports spinal alignment, reduces muscle tension, and helps prevent worsening back pain
• Pressure distribution: Avoiding excessive force on one area
• Muscle tension: Preventing unnecessary strain from awkward positions

The right position doesn’t just feel better—it helps your body recover overnight.

Sleeping on your back is often considered the best position for many people, as it is one of the most supportive positions for the spine. This position helps keep the spine aligned and the head and neck in a neutral position, which can reduce strain and discomfort.

When placing a pillow, back sleepers should use a contoured pillow to help maintain proper neck alignment and further support the natural curve of the spine.

A supportive mattress is also important for back sleepers. A firm or medium-firm mattress provides support for the spine and distributes pressure from the body more evenly.

Why it helps:

• Promotes neutral spinal alignment
• Evenly distributes body weight
• Reduces pressure points
• However, the key is proper support.

Pillow placement for back sleepers:

• Place a pillow under your knees
• This helps maintain the natural curve of your lower back
• It reduces strain on the lumbar spine

You can also:

Use a small rolled towel under your lower back for added lumbar support

Who it works best for:

• People with general lower back discomfort
• Those who can comfortably lie flat without neck strain

Side sleeping is a popular position for back pain relief and is another effective option—especially for those who find back sleeping uncomfortable.

This position helps maintain the spine's natural alignment, reducing pressure and avoiding twisting or curving of muscles and nerves. Side sleeping with knees drawn slightly towards the chest can open the space between vertebrae and lessen tension on spinal discs.

When using this position, choosing the right pillow is important to support proper neck and head alignment, which helps reduce pressure points and maintain spinal neutrality.

Why it helps:

• Reduces pressure on the spine
• Can improve comfort for people with hip or joint sensitivity

But alignment is crucial.

Pillow placement for back pain (side sleepers):

• Place a firm pillow between your knees
• This keeps your hips aligned
• Prevents your top leg from pulling the spine out of position

Additional tips:

• Keep your ears, shoulders, and hips in a straight line
• Avoid twisting your torso

According to Sleep Foundation, proper alignment in side sleeping can significantly reduce strain on the lower back. (https://www.google.com/search?q=https://www.sleepfoundation.org/sleeping-positions/best-sleeping-position-for-lower-back-pain)

The fetal position—lying on your side with knees drawn up—is common, especially among people with back pain. This position, where you curl your knees slightly toward your chest, may provide relief for herniated discs or sciatica by reducing pressure on the spine. It can also help people with spinal stenosis by opening up space between the spinal bones and relieving nerve tension, which can provide relief from discomfort.

When it helps:

• Can open up spaces between vertebrae
• May relieve pressure in certain conditions

When to be cautious:

Curling too tightly can:

• Increase muscle tension
• Round the spine excessively
• Strain the neck and lead to upper back pain

How to modify it:

• Keep a gentle bend in your knees
• Avoid pulling them too close to your chest
• Use a pillow between your legs

Think of it as a relaxed side position—not a tight curl.

Some positions tend to place more strain on the lower back. In particular, it is generally best to avoid stomach sleeping if you have back pain. Sleeping on your stomach is typically discouraged for those with back pain because it puts pressure on the spine and forces the neck into a twisted angle.

1. Sleeping on Your Stomach

This is generally the least recommended position.

Why it can cause issues:

• Forces the spine into an unnatural curve
• Strains the neck due to head rotation, which can lead to neck pain from misalignment
• Increases pressure on the lower back

If you must sleep this way:

• Place a thin pillow under your hips
• Use a very low pillow (or none) under your head

2. Poor Pillow Support

Even a good position can become problematic with the wrong pillow setup.

Common issues:

• Pillow too high → neck misalignment
• Pillow too flat → lack of support
• No leg support → hip imbalance

• Pillow under knees → reduces lumbar strain
• Optional small support under lower back

• Pillow between knees → aligns hips
• Optional pillow hugged in front → supports shoulders

• Choose a pillow that keeps your neck aligned with your spine
• Avoid tilting your head too far up or down

Your mattress should:

• Provide a supportive mattress that supports natural spinal curves and offers enough support for your back
• Prevent excessive sinking or stiffness

A soft mattress may feel comfortable at first but often lacks enough support for adults, potentially leading to back pain. Using a soft mattress topper can be an affordable way to increase softness without sacrificing support, especially if your current mattress is too firm. A firm or medium-firm mattress distributes pressure from the body more evenly, which can reduce pain when lying down or after getting up. It is also recommended to replace your mattress every seven to ten years, as mattresses soften over time and this can affect spinal alignment during sleep.

According to Keck Medicine of USC, a medium-firm mattress often works well for people with lower back pain, though comfort preferences vary. (https://www.keckmedicine.org/blog/the-best-and-worst-sleep-positions-for-back-pain/)

• Reduces muscle stiffness
• Improves comfort in your chosen position
• Supports better pressure distribution

Simple techniques include:

• Gentle stretching
• Warm showers
• Breathing exercises

Lying on the mat for 15–20 minutes provides consistent tactile stimulation

This sensation can:

• Encourage awareness of tight areas
• Help muscles in the back and shoulders relax
• Shift focus away from discomfort or stress

1. Lie on the mat in a comfortable position
2. Focus on slow, steady breathing
3. Allow your body to gradually settle

When muscles are more relaxed:

• It’s easier to maintain proper sleep posture
• You’re less likely to toss and turn
• Your chosen sleeping position becomes more comfortable

• This is not a treatment for back pain
• Results vary between individuals
• It works best alongside good posture and sleep habits

Think of it as a complement to alignment—not a replacement for it.

• Back or side sleeping preferred
• Avoid prolonged stomach sleeping

• Under knees (back sleepers)
• Between knees (side sleepers)
• Proper neck support

• Supportive but comfortable
• Not too soft or too firm

• Relax muscles before bed
• Reduce tension and stress

Both can be effective.

• Back sleeping supports spinal neutrality
• Side sleeping can reduce pressure and improve comfort

The best choice depends on what feels most natural and sustainable for you.

It depends on your position:

• Back sleepers → under the knees
• Side sleepers → between the knees

This helps maintain alignment and reduce strain on the lower back.

Possible reasons include:

• Poor sleep posture
• Lack of support from your mattress or pillows
• Muscle tension from the day

Addressing these factors can often improve nighttime comfort.
