Birthing in water aids in the physiological and psychological process and is extremely beneficial to a birthing mother. One can either give Birth in a pool of water (Birthing), or use warm water as a medium to relax (Hydrotherapy). It not only helps soothe the mother during contractions, but also helps with freedom of movement allowing for an upright posture that enables descent of the fetal head. The warm calming water encompasses the mother's abdomen allowing her to relax her muscles and ligaments, creating free movement and increasing the pelvic diameters. This type of environment is greatly supported and monitored by skilled midwives and trained staff.
