Lighting impact on the emotional expression of pregnant women: A randomized clinical trial

Abstract

Objective: To identify and compare the emotional expression of pregnant women during the stage of expulsion under common and regular lighting and low lighting. Methods: Pragmatic, randomized controlled clinical trial. Ninety-five pregnant women were selected, and divided into two groups: common and regular lighting and low lighting in the delivery room. Results: The most evident emotion during the stage of expulsion is anger (33.9%). The differences between the study groups regarding the presence of emotions are significant: fear (p< 0.0001), disgust (p = 0.0091), and sadness (p = 0.0060) were more evident for the group under common and regular lighting. The group under low lighting expressed more joy (p< 0.0001) and anger (p< 0.0001). All pregnant women finished their deliveries feeling joy. Conclusion: Low lighting provides a series of emotions that respect and help women's physiology during the stage of expulsion in labor.
