Easing the transition to the outside
The main reason for immersing pregnant women in water during labour and especially during childbirth is to make it easier for the newborn to transition from the mother's amniotic fluid to the outside world.
The main advantages of this approach are that it makes mothers more comfortable and helps them relax, advocates say. They have less pain, don't require painkillers, avoid perineal tears (since warmth relaxes perineal tissue), need less intervention with medical instruments and, by extension, spend less time in labour.
Aside from these clinical benefits, water birth helps women take back ownership of their bodies and their birthing process, Poder said.
“Childbirth has become highly medicalized. Water birth takes this major life event out of the purely clinical domain while placing women in an environment that's more responsive to their needs. It's a way for them to take back control over their destiny.”
Although there are risks (of the baby breathing in water, of infection, of difficulty seeing the perineum), Poder stresses that the scientific literature indicates that these risks are minimal when adequately supervised and are comparable to the risks posed by conventional labour.
“Water birth is not recommended when there are complications, such as breech births, but it is very safe for low-risk births," said Poder. "We just need to open everyone’s minds so more birthing pools are installed in health facilities, and so we can do a better job of listening to what women want.”
