Back Sleeping Can Support Spinal Alignment
Key takeaway
Back sleeping can promote relatively neutral spinal alignment in healthy adults, but fabricated-precision percentages should be avoided—and chronic back-pain patients may do better on their side.
- Back sleeping can keep the spine relatively neutral for many people.
- Stomach sleeping more often twists the neck and over-extends the low back.
| Claim | Scientific Observation | Impact Magnitude | ||
|---|---|---|---|---|
| Supine neutrality | Often closer to neutral than prone | Qualitative | ||
| Pressure patterns | Differ by position/mattress | Individual comfort | ||
| 12–18% deviation claim | Unverified precision | Removed | ||
| Chronic LBP | May prefer side sleeping | Keep caveat vs SLEE-08 |
