Is Sleeping On Your Stomach Bad?

Falling face-first can lead to aches and pains — especially if that describes how you hit the sheets at night to go to sleep.

Sleeping face down on your stomach can put extra stress on your back, neck and shoulders. That little bit of tension can add up over seven or eight hours, leaving you feeling a little worse for wear by the time the sun rises.

So, how can lying still and doing nothing make your muscles hurt? Chiropractor Andrew Bang, DC, has your answer and some tips to help you rest a bit easier.

Should you sleep on your stomach?

Let’s get right to the point: The answer to this question is usually NO, especially when it comes to treating your spine right.

Studies show that your choice of sleeping position can increase or decrease spinal pain, notes Dr. Bang. That’s a big deal, given the massive spike in neck and back pain reported in recent years.

Sleeping on your side or back is considered the best for your back and neck. (Learn more about these positions and variations.)

“You spend about one-third of your life sleeping,” says Dr. Bang. “How you position yourself during that time matters. Your goal should be to take as much pressure as possible off your joints and muscles.”

Sleeping prone on your stomach is generally not recommended. Here’s why:

Back pain

Sleeping comfortably is all about body mechanics. “You have to keep your spine in alignment, just like your car,” explains Dr. Bang. “If you hit a bump with your car, you can still drive — but you feel a shudder and know it’s not good.”

In the same way, bad postural habits when you sleep aren’t good for your body. Sleeping on your stomach throws your alignment off by flattening and abnormally twisting your spine’s ideal curve.

“It puts added stress on your lower back — and that’s a part of the body that most of us are already taxing in our day-to-day activities,” says Dr. Bang. “Stomach sleeping doesn’t give those muscles a chance to rest and recover.”

Neck pain

Sleeping with your belly against your bed requires a turn of your head one way or the other to avoid suffocating in your pillow. That twist of your noggin pulls your body out of its natural alignment for a looong period of time.

Imagine locking your neck into that position for hours at a time during the day. It would eventually start to hurt, right? The same principle applies when you’re snoozing.

“Stretching your neck muscle for that long creates soreness,” says Dr. Bang. 

Sleeping on your stomach also extends your neck backward, compressing your spine. This can lead to a tingling sensation as your arm “falls asleep” from constricted blood flow and compressed nerves.

Shoulder pain

What do you do with your arms if you sleep on your stomach? Most people naturally raise them up, maybe even tucking one arm (or both) under the pillow. That positioning keeps tension on your shoulder joint.

“You’re creating a situation that can eventually lead to rotator cuff problems or other shoulder issues,” states Dr. Bang.

Facial wrinkles

Sleeping face down on your stomach basically mushes your facial skin, which brings consequences. Researchers found that a prone sleeping position brings wrinkle-forming compression and stress.

Babies and sleep position

While stomach sleeping can lead to aches and pains for adults, it can be deadly for infants.

Safe Sleep” recommendations by the American Academy of Pediatrics emphasize that babies should always be placed on their backs to sleep. Sleeping on their belly carries an elevated risk of sudden infant death syndrome (SIDS).

How to stop stomach sleeping

If you’re a regular stomach sleeper and want to change your overnight position, it can be done, says Dr. Bang. His advice to help with the transition? Use pillows.

A few well-placed pillows can basically serve as bumpers that keep you from turning onto your stomach during the night. Over time, you can train your body to remain in the side or back position.

“It takes a little practice,” he says, “but if you’re sleeping on your stomach and make the change, odds are you’re going to wake up in the morning feeling better.”
