This study is looking at how different room lighting (Room light/light bulb) might affect uterine contractions (the tightening of your womb) and how labor progresses during pregnancy. Researchers believe that reducing or eliminating light in the evening and night could help your body naturally release melatonin, which might encourage contractions in late pregnancy. The study aims to see if changing room light can help achieve a vaginal birth and reduce the need for C-sections. You may be able to join if you are pregnant, between 18 and 42 years old, and medically cleared. The study is currently unclear on its recruitment status and plans to enroll 100 participants.
