How to Sleep if Your Neck Hurts: Position, Pillow Height and Neck Comfort

Your pillow sets your neck's angle for seven or eight hours a night. The goal is simple: keep your head level with the rest of your spine, so your neck isn't holding an awkward angle all night. Here's how to check that for the way you actually sleep.

From Dr. Irina Velichko, D.C. and Dr. Ben Glass, D.C., The Shift Chiropractic, Downtown Oakland

Proper neck posture while sleeping, position by position

None of this is magic. It's the same idea as setting up a desk: put the support where your body needs it, then stop holding the strain yourself.

On your back

Pillow
Thin enough that your chin isn't pushed toward your chest. Your forehead and chin should sit roughly level.
Knees
A pillow under your knees takes tension off your lower back.

On your side

Pillow
Thick enough to fill the space between your ear and the mattress, so your head stays level instead of tipping down toward the bed or up toward the ceiling.
Knees
A pillow between your knees keeps your top leg from dropping and twisting your pelvis.

On your stomach

Neck
Stomach sleeping keeps your neck turned to one side for hours. If that's you, try starting the night on your side with a pillow hugged in front of you.
If you stay there
Use a very thin pillow or none under your head, and a thin pillow under your hips so your lower back sags less.

A two-minute pillow check

You don't need a new pillow to start. Check the one you have, lying the way you usually fall asleep:

  1. Get a second opinion. Ask someone to look at you from the side and the front, or prop your phone up and take a photo.
  2. On your back: your forehead and chin should be roughly level. If your chin tips toward your chest, the pillow is too high. If your head tips back, it's too low.
  3. On your side: the middle of your nose should line up with the middle of your chest. If your head tips down toward the mattress, add height with a folded towel under the pillowcase. If it tips up, go thinner.
  4. Give it a week. Pillows compress through the night, and a soft mattress lets your shoulder sink further, so a height that looks right at bedtime can be different by 3 a.m. Adjust by small amounts and live with each change for a few nights.
Your day sets up your night. If your neck spends the day tipped toward a screen, it goes to bed already tired. Set up your chair, desk and monitor with the desk setup calculator, and see how the load on your neck changes as your head tips forward.

Why your neck can be stiff when you wake up

Usually it's the position, not the night. Seven or eight hours with your head turned to one side, or propped up too high, and the muscles and joints on one side stiffen up. The two things to check are the ones above: your pillow height, and whether you sleep on your stomach.

In the morning, go easy. Start with slow nods and slow turns, within comfort, before you reach for your phone.

Get checked promptly if neck pain comes with numbness, tingling or weakness in an arm or hand, a fever, a severe headache, or trouble with balance. Those need a medical assessment, not a new pillow.

Snoring, breathing pauses and your neck

A pillow page is a good place to say this plainly: some sleep problems aren't about comfort at all. Obstructive sleep apnea is a condition in which the airway narrows or closes again and again during sleep. It's diagnosed with a sleep study and treated by physicians. Chiropractic care doesn't treat sleep apnea, and a pillow or a posture change isn't a substitute for being evaluated.

Why neck size shows up in sleep screening

Clinicians often screen for sleep apnea with the STOP-Bang questionnaire, eight yes-or-no items developed at the University of Toronto. Neck size is one of them: the current version counts a shirt collar of 16 inches (40 cm) or larger. It's a screening question, not a diagnosis, and only a sleep study can tell you whether you have sleep apnea.

Forward head posture: an association, not a cause

Several studies have found that people with sleep apnea tend, on average, to carry their head further forward, with a larger angle between the head and neck. That's an association, not proof that posture causes sleep apnea. One of the research groups that described it suggested the arrow may point the other way: a forward, tipped-up head may be the body's way of holding a narrow airway open while awake. So if you notice forward head posture, don't treat it as a sign you have sleep apnea. And don't expect posture work to change sleep apnea either.

See a sleep physician if:

  • you snore loudly or heavily, most nights,
  • someone has seen you stop breathing, choke or gasp in your sleep, or
  • you wake up unrefreshed or fight sleepiness during the day, even after a full night in bed.

Start with your primary care doctor, or find an accredited sleep center through the American Academy of Sleep Medicine's sleep center directory.

If your neck is stiff most mornings

A stiff neck that keeps coming back is worth a proper look. At The Shift we check how each segment of your neck moves, look at your desk and sleep setup with you, and explain what we find and what we'd suggest, with the cost in writing before you agree to anything.

Sleep and neck questions

Aim to keep your head level with the rest of your spine. On your back, use a pillow thin enough that your chin isn't pushed toward your chest. On your side, use a pillow that fills the space between your ear and the mattress so your head doesn't tip up or down. Stomach sleeping keeps your neck turned for hours, so try starting the night on your side with a pillow hugged in front of you.

Your head level with the rest of your spine, not tipped up, down or to the side. On your back, your forehead and chin should sit roughly level; if your chin tips toward your chest, the pillow is too high. On your side, the middle of your nose should line up with the middle of your chest. Stomach sleeping keeps your neck turned to one side for hours.

Usually it's the position, not the night. Seven or eight hours with your head turned to one side, or propped too high, leaves the muscles and joints on one side stiff. Check your pillow height and whether you sleep on your stomach. In the morning, start with slow nods and turns within comfort. If it keeps happening, or comes with numbness, weakness, fever or a severe headache, get it checked.

The one that keeps your spine in a line. On your back, put a pillow under your knees. On your side, put a pillow between your knees so your top leg doesn't drop and twist your pelvis. If you sleep on your stomach, a thin pillow under your hips keeps your lower back from sagging as much.

No. Sleep apnea is diagnosed with a sleep study and treated by a physician. If you snore heavily, someone has seen you stop breathing or gasp in your sleep, or you wake unrefreshed, talk to a sleep physician or your primary care doctor.
