How does water immersion during labor benefit expectant mothers and their babies?

Water immersion during labor can benefit expectant mothers and their babies by providing pain relief, promoting relaxation, and potentially reducing the need for medical interventions. The buoyancy of water can help ease the discomfort of contractions, while the warmth and support of the water can help mothers relax and feel more in control. Additionally, water immersion may help to increase blood flow to the uterus, which can potentially improve oxygen supply to the baby.
