Lumbar Curvature

Lumbar curvature determines how much unsupported space exists between the lower back and the mattress. The article links maternal diet quality during pregnancy to differences in spinal development in offspring. A soft surface can misalign a person with a flat lower back by allowing the mid-body to sink too far. Dense, heavy bodies with flat lower backs are especially poorly matched to soft mattresses. Prenatal nutrition is presented as one factor shaping later lumbar curvature.
