How Your Sleeping Position Can Affect Aches, Pains & Spinal Comfort

We spend roughly a third of our lives sleeping, so the way we position our body at night can have a surprisingly big impact on how we feel when we wake up.

If you regularly wake up with neck stiffness, low back pain, shoulder tension, or general aches, your sleeping position and pillow setup may be worth taking a look at.

The good news? You don't necessarily need to completely change the way you sleep. A few small changes can help your body feel more supported and comfortable throughout the night.

Back Sleepers…

Sleeping on your back can be a great position for keeping your spine relatively neutral—but your pillow setup matters.

Your pillow should support the natural curve of your neck without pushing your head too far forward. A cervical pillow can be helpful because it is designed to provide additional support around the neck.

Your goal is for your head and neck to feel comfortably supported rather than tilted upward or dropping backward.

The next thing to pay attention to is your lower back. If you experience low back discomfort while sleeping on your back, try placing a small pillow underneath your knees. This can reduce the amount of extension in your low back and may make the position more comfortable.

Side Sleepers… 

Side sleeping is extremely common, but it can create its own set of challenges if your hips, shoulders, and neck aren't well supported.

What can you do to better support your posture while sleeping in the side lying position? One of the easiest adjustments is placing a pillow between your knees and/or thighs.

This can help keep your pelvis and hips in a more comfortable position instead of allowing your top leg to fall forward and rotate your pelvis.

Finding the right pillow height is also one of the most important—and often overlooked—parts of side sleeping.

Your head should remain relatively aligned with your spine rather than bending downward toward the mattress or being pushed upward. The ideal pillow height depends on factors like your body size, shoulder width, sleeping position, and mattress.

And that's where having the right pillow can make a big difference.

Lastly, if you tend to sleep with your arms curled up in front of you, try hugging a pillow.

This can give your upper arm somewhere to rest and may help reduce the tendency to curl your shoulders forward while you sleep.

What About Sleeping on Your Stomach?

Stomach sleeping is a big NO. Because you have to turn your head to one side to breathe, your neck remains rotated for an extended period of time. Imagine holding your head in rotation for 8 hours straight during the day… your muscles are going to get irritated and try to pull you back to neutral. When you’re sleeping on your stomach, your neck physically can not move back to neutral, so, your muscles will likely spasm and you’ll wake up feeling like you “slept wrong.”

If you already experience neck pain, stiffness, headaches, or shoulder discomfort, stomach sleeping may be contributing to your symptoms.

If stomach sleeping is the only way you can comfortably fall asleep, you should gradually train yourself to transition to side or back sleeping and see how your symptoms change.

Your Mattress Matters, Too

Your sleeping position isn't the only factor.

A mattress that is too soft may allow your body to sink excessively, while one that is too firm may create uncomfortable pressure points—particularly around your shoulders and hips if you're a side sleeper.

The goal isn't to find the "perfect" mattress or sleeping position. It's to find a setup that allows you to stay comfortable and supported without constantly waking up to readjust.

Movement Is Still Medicine

Even with the perfect pillow and mattress, staying in one position for 7–9 hours means your body isn't moving much. That's one reason you may feel stiff when you first get out of bed.

Try incorporating some gentle movement into your morning routine:

• Take a short walk

• Perform gentle spinal mobility

• Stretch your hips and shoulders

• Move your neck through a comfortable range of motion

• Get out of bed instead of staying stationary for a long time

Your body doesn't need to be perfectly positioned all night. It needs the ability to move, adapt, and recover.

We Carry Personalized Pillowise Pillows in Our Clinic

At Regional Chiropractic Center, we carry Pillowise pillows, which are designed to provide personalized neck support based on your individual measurements.

Rather than choosing a pillow based solely on whether you're a "small," "medium," or "large" person, we can measure you in the clinic to determine the pillow size that's best suited to your body.

A properly sized pillow can help keep your head and neck in a more neutral position while you sleep, which may be especially helpful if you frequently wake up with neck pain, stiffness, or headaches.

If you're not sure whether your current pillow is actually supporting you properly, ask us about getting measured for a Pillowise pillow at your next visit.

The Bottom Line

There isn't one sleeping position that's perfect for everyone. Your anatomy, previous injuries, mattress, pillow, and personal comfort all play a role.

If you're consistently waking up with aches and pains, try making one change at a time—adjust your pillow, add a pillow between your knees, support your knees while back sleeping, or experiment with a different sleeping position.

And don't underestimate the importance of your pillow. The right pillow should support your neck—not force it into a position that doesn't feel natural.

If you'd like to see whether a personalized pillow could help, stop by Regional Chiropractic Center and ask us about Pillowise. We can measure you in the office and help determine the size that's best suited for your body and sleeping position.
