Some ways to naturally help the water break when pregnant include asking a practitioner to strip the membranes, walking, having sex and nipple stimulation. Although medically unproven, some women believe that spicy foods, pineapple and evening primrose oil also help break their waters.
Stripping the membranes, the most medically recommended route, is done by a doctor or midwife, who uses her fingers to separate the amniotic sac from the uterus walls. This helps to irritate the uterus, stimulating contractions that begin hours to days afterward. This procedure helps the water break for many women, but it doesn't work all the time.
Walking encourages the baby to drop into the birth canal, and this added pressure can trigger contractions or make the water break. Sex is often recommended by medical professionals to help bring on labor because there are prostaglandins in semen that soften the cervix. Additionally, having an orgasm releases the feel good hormone oxytocin, a necessary hormone in the onset of labor. Nipple stimulation works in much the same way; it's done by rolling the nipple and areola between your thumb and forefinger, mimicking the suckling of a baby.
Spicy foods and pineapple are thought to irritate the bowels, thus irritating the uterus to stimulate contractions and break the water. Again, this is not medically proven.
