Most of us spend roughly a third of our lives asleep, yet very few people stop to think about what that time is doing to their spine. Sleep is supposed to be restorative, a chance for your muscles to relax, your discs to rehydrate, and your nervous system to reset. But if you’re waking up with stiffness, neck pain, or a sore lower back, your sleep position might be working against you rather than for you. Understanding proper sleep positions for a healthier spine is one of the simplest, most accessible steps you can take toward feeling better every day — no equipment required, no prescription needed.
Here in Lisle, IL, Dr. Paul Rieselman and the team at Northstar Integrated Health & Physical Medicine Center hear this concern all the time. Patients come in describing morning aches that they’ve just accepted as “normal.” The good news? They’re usually not. Your body can do incredible things during sleep when given the right support. This article will walk you through everything you need to know about how your sleep position affects your spine, which positions are safest, and what you can do starting tonight to protect your spinal health.
What Does “Proper Sleep Position” Really Mean?
A proper sleep position is one that keeps your spine in a neutral alignment while you rest. Neutral alignment means your head, neck, shoulders, hips, and lower back are positioned in a way that doesn’t place excessive stress or strain on any one area of the spine. In the simplest terms: your spine should look roughly the same while you sleep as it does when you’re standing with good posture.
Why Sleep Position Matters for Your Spine
Your spine is an incredibly complex and dynamic structure. It’s made up of 33 vertebrae, dozens of joints, over 100 muscles, and a network of discs that act as shock absorbers between each vertebra. During the day, these discs are under constant compression from gravity and movement. At night, lying down takes that gravitational load off the spine, and the discs actually absorb fluid and recover. This is a critical process, but only if the spine is properly supported while you sleep.
When you sleep in a poor position, certain muscles are forced to stay active all night long to compensate for the awkward angle. Others become overstretched and strained. Joints can be compressed or torqued in ways that lead to inflammation and stiffness. Over time, consistently sleeping in bad positions doesn’t just cause morning aches. It can contribute to chronic neck and back problems, accelerated disc wear, and even changes in spinal curvature.
The American Chiropractic Association notes that musculoskeletal problems are among the most common reasons people lose sleep or wake up in pain. Research also consistently supports the idea that spinal alignment during sleep plays a meaningful role in back pain outcomes. Dr. Paul Rieselman often reminds patients at Northstar Integrated Health & Physical Medicine Center in Lisle, IL, that what you do during the eight hours you sleep can either undo or reinforce the work done in the office. Sleep is, quite literally, part of your treatment plan.
The Best (and Worst) Sleep Positions for Spinal Health
Sleeping on Your Back: The Gold Standard
Sleeping on your back is widely considered the most spine-friendly position available to you. When you lie on your back, your weight is distributed fairly evenly across the entire length of your spine. There are no sharp angles pulling the neck sideways or forcing the lower back into an unnatural curve. Your head, neck, and spine can all line up as they should. Placing a pillow under your knees can help preserve the natural lumbar curve and take additional pressure off the lower back, making this position even more comfortable for people who struggle with low back pain.
The one caveat: back sleeping is not ideal for people who snore heavily or have obstructive sleep apnea, as the tongue and soft tissues can fall back and obstruct the airway. If that applies to you, speak with your physician and consult with Dr. Paul Rieselman about how to adapt your sleeping setup accordingly.
Side Sleeping: A Close Second
Side sleeping is the most common position, and for most people, it’s a perfectly good choice as long as it’s done correctly. The key is keeping your spine in that neutral alignment from head to hip. That means your pillow needs to fill the gap between your ear and your shoulder so your head isn’t drooping down or propped up too high. Placing a pillow between your knees is also highly recommended, as it prevents your top leg from pulling your pelvis forward and rotating your lower spine throughout the night.
Side sleeping in the fetal position — knees pulled tightly to the chest — is a common habit but one that can cause problems over time. Curling tightly compresses the discs on one side and can contribute to upper and lower back stiffness, as well as restricted breathing. A gentle side position with a slight bend at the knees is much more spine-friendly than the full curl.
Stomach Sleeping: The Hardest on Your Spine
Stomach sleeping is, unfortunately, the most popular problematic position. When you sleep face down, you have to rotate your head to one side just to breathe, and keeping your neck rotated for hours at a time places enormous strain on the cervical spine. The lower back also suffers in this position, because the belly sinks into the mattress and forces the lumbar spine into excessive extension. For people who already have disc issues, neck problems, or lower back pain, stomach sleeping can significantly worsen symptoms.
Breaking the stomach-sleeping habit takes time and a little patience. Placing a pillow under your abdomen (rather than under your head) can reduce the lumbar strain if you truly can’t avoid it during the transition period. The goal, over time, is to migrate toward back or side sleeping for the long haul.
Pillows, Mattresses, and the Support Your Spine Needs
Even the best sleep position in the world won’t fully protect your spine if your pillow or mattress isn’t doing its job. Pillow selection should be based on your primary sleep position. Back sleepers generally do best with a thinner pillow that supports the natural cervical curve without pushing the chin toward the chest. Side sleepers need a firmer, thicker pillow that fills the distance between the head and shoulder. A pillow that’s too thin allows the head to sag; one that’s too thick pushes it upward. Both create strain on the cervical vertebrae and the muscles surrounding them.
Mattress firmness is a nuanced topic, and the “best” mattress truly does vary from person to person. A mattress that is too soft allows the hips to sink, causing the spine to bow downward. One that is too firm can create pressure points at the hips and shoulders for side sleepers, leading to compensatory movements throughout the night. Medium-firm mattresses tend to perform well for most people with back concerns, and evidence from the conservative care world suggests that medium-firm support is often beneficial for non-specific low back pain. The team at Northstar Integrated Health & Physical Medicine Center in Lisle can offer personalized guidance based on your specific spinal condition and sleep habits.
How Chiropractic Care Fits Into Better Sleep and Spinal Health
Chiropractic care takes a whole-body, non-invasive approach to spinal health. When the vertebrae of the spine are misaligned, whether from poor posture, physical stress, or yes, chronic bad sleeping habits, the joints can become restricted, muscles tighten to compensate, and nerve function can be affected. Chiropractic adjustments aim to restore proper joint mobility, reduce muscular tension, and support the body’s natural ability to heal and regulate itself.
Many patients at Northstar Integrated Health & Physical Medicine Center in Lisle, IL, report that after receiving chiropractic care, they sleep more soundly and wake with less stiffness. This likely happens for a few reasons: the reduction in joint irritation allows muscles to genuinely relax during sleep, and improved spinal alignment means the body doesn’t have to work as hard to maintain position throughout the night. Research from organizations like the NCCIH suggests that chiropractic care can be a helpful part of a conservative, non-surgical approach to managing back and neck pain, which are two of the most common sleep disruptors.
Dr. Paul Rieselman integrates chiropractic adjustments with a broader integrative approach at Northstar Integrated Health & Physical Medicine Center, which may include soft tissue therapy, corrective exercises, and patient education around posture and sleep hygiene. The goal is never to simply manage symptoms; it’s to find the underlying cause and give your body the tools it needs to function well every single day, including while you’re resting.
Practical Tips for Improving Your Sleep Position Tonight
Changing a sleep habit isn’t something that happens overnight — no pun intended. But there are practical steps you can start immediately that will make a real difference over time. Begin by evaluating your current pillow. If it’s more than a year or two old, has lost its shape, or you wake up with neck pain regularly, it’s likely past its prime and worth replacing with one suited to your position.
If you’re a side sleeper, try placing a standard pillow between your knees tonight. It might feel awkward at first, but most people find it surprisingly comfortable within a few nights. For back sleepers, tucking a rolled-up towel or a small pillow under the knees creates that slight flexion that takes pressure off the lumbar discs.
Pay attention to how you’re getting into and out of bed, too. Twisting at the waist while lying down or doing a quick sit-up to get up can stress the lumbar spine significantly, especially first thing in the morning when the discs are still rehydrated and the muscles haven’t warmed up. Instead, roll to your side, use your arms to push up, and let your legs drop to the floor as a natural counterweight. It’s a small change that protects the lower back from unnecessary strain day after day.
When to See a Chiropractor About Sleep-Related Spinal Pain
Some morning stiffness that resolves within 20-30 minutes after getting moving is fairly common and often responds well to position changes and supportive equipment. However, there are clear signs that it’s time to seek professional evaluation. If your pain persists throughout the day, disrupts your sleep consistently, or is getting progressively worse over weeks, don’t wait. Pain that radiates into the arms or legs, causes numbness or tingling, or is accompanied by weakness deserves prompt attention.
There are also red flags that go beyond chiropractic care and require immediate medical evaluation. These include severe pain following an injury or fall, pain accompanied by fever, unexplained weight loss, loss of bladder or bowel control, or pain that is constant and does not change with position. In those situations, Dr. Paul Rieselman and the team at Northstar Integrated Health & Physical Medicine Center will ensure you receive appropriate referrals and coordinated care.

Myths vs. Facts About Sleep Positions and Spine Health
Myth: A firm mattress is always better for your back.
Fact: Mattress preference is highly individual. While a mattress that’s too soft can cause the spine to sag, an overly firm mattress can create pressure points especially for side sleepers. Evidence suggests that medium-firm mattresses tend to support spinal comfort for a wide range of body types and conditions, but the best mattress is ultimately the one that keeps your spine neutral and lets you sleep without pain.
Myth: If you’ve slept on your stomach your whole life, you can’t change.
Fact: Habits can absolutely be changed with intention and gradual practice. Using a body pillow on one side of you makes it harder to roll onto your stomach. Starting on your side or back each night, even if you end up shifting, trains your body over time. Most patients who commit to transitioning notice meaningful improvement within a few weeks.
Myth: Morning back pain is just part of getting older.
Fact: While some age-related changes in the spine are normal, waking up in pain every day is not something you simply have to accept. In many cases, the culprit is a combination of sleep position, unsupportive bedding, and underlying spinal dysfunction that hasn’t been addressed. These are all modifiable factors. Dr. Paul Rieselman works with patients of all ages at Northstar Integrated Health & Physical Medicine Center to identify what’s driving their discomfort and develop a plan to address it.
Myth: Chiropractic care is only for people who’ve had an injury.
Fact: Chiropractic care is appropriate for a wide range of patients, from those recovering from injuries to people seeking to maintain spinal health proactively. Many patients in Lisle, IL, come to Northstar Integrated Health & Physical Medicine Center simply because they want to feel better, move better, and sleep better. Preventive and wellness-focused care is a core part of what we do.
Myth: You should sleep flat with no pillow for the straightest spine.
Fact: Your spine is not meant to be completely straight. It has natural curves that need to be supported, not flattened. Sleeping without any pillow typically causes the head to fall to one side or sink too far back, straining the cervical spine. The right pillow doesn’t eliminate your neck curve; it supports it.

Frequently Asked Questions
What is the best sleep position for lower back pain?
Back sleeping with a pillow under the knees is generally considered the most supportive position for lower back pain, as it maintains the natural lumbar curve and distributes spinal load evenly. Side sleeping with a pillow between the knees is also a good option. It’s best to avoid stomach sleeping if you have low back issues, as it tends to increase lumbar extension and strain.
Can my pillow really cause neck pain?
Yes, absolutely. A pillow that is too high or too flat fails to support the natural cervical curve, forcing the neck into an unnatural angle for hours at a time. Over time, this can contribute to muscle tension, joint stiffness, and chronic neck pain. Choosing a pillow matched to your sleep position is one of the simplest ways to reduce neck discomfort.
How long does it take to notice improvement after changing sleep positions?
Most people notice some change within one to two weeks of consistently adjusting their sleep position and using proper support. However, if there is underlying spinal dysfunction contributing to the pain, chiropractic evaluation may help speed and sustain those improvements. Lasting change typically comes from a combination of better sleep habits and addressing the root cause of the discomfort.
Is it okay to sleep on my side during pregnancy?
Side sleeping, particularly on the left side, is generally recommended during pregnancy, especially in the later trimesters. Placing a pillow between the knees and supporting the belly with another pillow can help maintain spinal alignment and reduce hip and lower back discomfort. Always consult your OB or midwife for guidance specific to your pregnancy.
Can chiropractic care help with sleep problems related to back or neck pain?
Chiropractic care may help by addressing the spinal misalignments and joint restrictions that contribute to pain and muscle tension — two major disruptors of restful sleep. While chiropractic care is not a treatment for sleep disorders themselves, reducing pain and improving musculoskeletal function often allows patients to sleep more comfortably and deeply. The team at Northstar Integrated Health & Physical Medicine Center can assess whether spinal issues are contributing to your sleep difficulties.
How do I know if my mattress is the reason for my back pain?
A helpful clue is whether your pain is worse in the morning and improves after you get moving. If you sleep well in hotels or guest beds but consistently wake up sore at home, your mattress may be a contributing factor. A mattress that is visibly sagging, more than seven to ten years old, or leaves you with pressure point soreness at the hips or shoulders is worth evaluating for replacement.
