Abstract: Water birth, defined as the process of labor and/or delivery occurring in a water-filled birthing pool, has gained increasing popularity as a woman-centered approach to childbirth. While considerable research has explored the physiological benefits of water immersion during labor, the psychological outcomes associated with water birth remain an emerging area of interest. Maternal psychological well-being during the perinatal period significantly influences childbirth satisfaction, maternal-infant bonding, breastfeeding success, and long-term mental health. This review examines current evidence regarding maternal psychological outcomes following water birth, including maternal satisfaction, perceived control, anxiety reduction, pain perception, emotional well-being, postpartum depression risk, birth trauma experiences, and maternal self-efficacy. Evidence from observational studies, systematic reviews, qualitative investigations, and comparative analyses suggests that water birth is associated with enhanced maternal satisfaction, reduced childbirth-related anxiety, improved sense of autonomy, and more positive birth experiences. The supportive environment created by warm-water immersion may contribute to neuroendocrine responses that facilitate relaxation and emotional comfort. Despite encouraging findings, limitations such as methodological heterogeneity, limited randomized controlled trials, and variations in water birth protocols necessitate cautious interpretation. Future research should prioritize longitudinal studies and standardized psychological outcome measures to establish stronger evidence regarding the mental health benefits of water birth. Understanding the psychological implications of water birth may assist healthcare professionals, particularly nurses and midwives, in providing evidence-based, woman-centered maternity care.
