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.
