Sleep
Pillow shape, side sleeping, and your neck
You spend a third of your life in one position. Here's how to make those hours work for your spine.
The goal: neutral, not propped
A pillow's job is to fill the gap between your head and the mattress so your neck keeps its natural curve. Too thick and your head is pushed forward all night; too thin and it drops back. Either way you wake up stiff.
By position
- Side sleeping: pillow height should roughly equal the width of your shoulder, keeping nose in line with sternum
- Back sleeping: thinner pillow, with support under the neck rather than just under the head
- Stomach sleeping: the hardest position on your neck — worth transitioning away from if you can
Knees and hips matter too
Side sleepers do better with a pillow between the knees to stop the top leg from rotating the pelvis. Back sleepers with low back pain often get relief from a small pillow under the knees.
When sleep is the symptom, not the cause
If you wake with the same pain regardless of pillow or position, the problem is usually structural rather than environmental. That's a measurement conversation, and it's a quick one.
