There is no single proven best sleeping position, but the evidence gives some pointers. In a home study of sleep posture, people who woke with neck pain spent more time in positions that strain the neck, and lying on the side was generally protective. For low back pain the position mattered less. Comfort, a supportive mattress and enough sleep matter at least as much as the position itself.
What the studies found
A study that measured sleep posture objectively at home compared people who woke with spinal symptoms with people who did not:1
- People with waking neck symptoms changed position more often, spent more time in provocative positions, and had more long stretches without moving in those positions.
- For waking low back symptoms, there were no clear differences in position from the comparison group.
- Side lying was generally protective against waking symptoms; lying on the back was not clearly protective compared with other positions.
- People with waking symptoms also slept worse.
Side lying appears to suit people who wake with neck pain best. For the lower back, sleep position seems to matter less. The evidence comes from observational studies, so position may follow pain rather than cause it.1
Position by position
| Position | Tips |
|---|---|
| Side | Pillow high enough to keep the head level with the spine; a pillow between the knees can ease the lower back |
| Back | A thinner pillow; a pillow under the knees can feel easier on the lower back |
| Front | Twists the neck for hours; if it suits you, use a very thin pillow or none, and a pillow under the hips |
Sleep matters more than the pose
Sleep and spinal pain are linked in both directions: pain disrupts sleep, and poor sleep lowers how much discomfort you tolerate.2 Protecting sleep is part of managing pain. See sleep and back pain.
Mattress and pillow
A 2021 review of 39 studies concluded that a medium-firm mattress tends to promote comfort, sleep quality and spinal alignment, and may reduce back pain more than a soft or very firm one, with body build and preferred position also playing a part.3 See choosing a mattress and choosing a pillow.
When to see a clinician
Pain that wakes you every night regardless of position, or night pain with fever, weight loss or a history of cancer, needs assessment. See red flags.
