First seen Nov 01, 2025 · Last updated Jun 23, 2026 · Updated 34 times
Summary
This study tests whether adjusting room light during labor can improve uterine contractions. Researchers believe darkness or red light may boost melatonin, a hormone that helps contractions. 100 pregnant women will have their light exposure and contractions monitored. The goal is to see if a simple light change can reduce failed inductions and C-sections.
