While giving birth to a baby comes with a number of consequences and difficulties for the mother and child, a new study found that water births are no more risky than land births and that women in the water group sustain fewer first and second-degree tears. University of Michigan researchers analyzed 397 waterbirths and 2025 land births from two midwifery practices. There were no differences in outcomes between waterbirth and land birth for neonatal intensive care admissions, and postpartum haemorrhage rates were similar for both groups. The results of the study were published in the journal Birth. Professional organizations tend to agree that women in labour should have access to water for comfort, but not all support birth in the water. This means hospitals must make women leave the tub before birth. During a water birth, babies take their first breath when removed from the tub. Until then, their lungs are filled with water, which is displaced when they hit the air and breathe.
