Waking Up With Neck Pain: Why It Happens and What to Check

Key takeaways

• Your neck stays in one position for hours at night, so a gap or a bend between your head, shoulder and mattress can matter.
• The right pillow height depends on your body, your sleeping position and your mattress, not on a single standard size.
• A pillow supports your neck; it is not a treatment. Pain with numbness, weakness or after an injury needs a healthcare provider.

Why do I wake up with neck pain?

There is rarely one answer. Common contributors include:

• Your sleeping position. Turning your head far to one side for hours, as many stomach sleepers do, keeps the neck rotated.
• Pillow height. A pillow that is too high pushes your head up and sideways. One that is too low lets it drop toward the mattress.
• Your mattress. A soft mattress lets your shoulder sink in. A firm one holds your shoulder up and leaves more space to fill.
• Daytime habits. Long hours at a desk or looking down at a phone can leave your neck tired before you go to bed.
• Stress and tension. Tight muscles do not always relax when you lie down.
• An older pillow. Filling can flatten and lose its support over time.

We can speak to the pillow part. We cannot tell you which of these is behind your pain, and research does not show that changing your pillow will make neck pain go away. What we can say is that a pillow that fits gives your neck even support, and that is a reasonable thing to check first.

How does pillow height affect my neck?

Think of the space between your ear and the mattress. When you lie on your side, your shoulder holds your body up and your head hangs in the gap above the mattress. The pillow has to fill that gap. When it does, your neck can stay in line with the rest of your spine. When it does not, your neck bends to make up the difference.

You would not walk around in shoes a size too small. A pillow that is a size too high or too low works the same way: you feel it most after a few hours. Our co-founder Thijs van der Hilst, a Dutch physiotherapist, compares pillow sizing to shoe sizing. A store that sells one size rarely has yours.

Does my sleeping position change what I need?

Yes. In general:

• Side sleepers need more loft to fill the space between the ear and the mattress. See our page on a pillow for side sleepers.
• Back sleepers need less loft, enough to support the curve of the neck without tipping the chin toward the chest. See back sleepers.
• Stomach sleepers usually need the lowest loft, so the head is not pushed back and up. See stomach sleepers.

If you change positions during the night, pick the position you fall asleep in as your starting point. Our tips on sleeping position go into more detail. For a broader overview, see the Yourzzz sleep guide.

What can I check tonight?

1. Look at your pillow. Is it flat, lumpy or older than you can remember? Pillows wear out, and you can read more on when to replace a pillow.
2. Notice your position. Pay attention to how you fall asleep and how you wake up. Is your head turned or tipped?
3. Think about your mattress. Is it soft, medium or firm? This changes how much your shoulder sinks in.
4. Check your daytime posture. Take breaks from screens and desks, and move your neck gently.
5. Keep notes. Write down how your neck feels in the morning for a while. Patterns are easier to see on paper.

When should I see a healthcare provider?

A pillow is not the answer to everything. Please talk to a doctor or other healthcare provider if you have:

• numbness, tingling or weakness in your arms or hands
• neck pain after a fall, accident or other injury
• severe headaches, fever or a stiff neck together with other symptoms
• pain that keeps getting worse or does not ease over time

A pillow that fits can support your neck while you sleep. It does not replace a diagnosis.

How is the Yourzzz pillow adjusted?

Most pillows come in one fixed height. Yourzzz is a pillow you adjust at home. You order it first, and when it arrives you adjust the filling to your body. The filling is premium memory foam flakes and polyester fibers. Removing filling makes the pillow lower and softer.

1. Order the pillow. It arrives with the filling inside.
2. Use the calculator. On /en/measure-now you enter your height (inches), weight (lbs), sleeping position (side, back or stomach) and mattress firmness (soft, medium or firm).
3. Take out the filling. The calculator tells you how much to remove and shows the final weight of the pillow. Use a kitchen scale. Without a scale, a 200 ml (6.8 fl oz) glass holds about 50 g (1.8 oz) of filling.
4. Keep the extra filling. Store it in the storage bag so you can adjust again later, for example if you change mattress.

The algorithm behind the calculator was developed by Thijs van der Hilst. The inner cover has a memory foam sheet with one firmer side and one softer side, so you can choose the feel you prefer. For more on this approach, read about adjustable loft and shredded memory foam pillows. If neck pain is your main concern, our page on neck pain and your pillow covers what to look for.
