What Is Water Birth? What Are Its Benefits and Risks?

Childbirth is a multidimensional process that simultaneously reveals the physiological capacity of the female body, psychological resilience, and its interaction with environmental conditions. In modern obstetrics and gynecology practice, not only the occurrence of birth itself but also how the mother experiences this process—how safe and in control she feels during labor—has gained increasing importance. This perspective has contributed to growing interest in alternative and supportive birth methods.

One of these methods, water birth, has been discussed more frequently in recent years by both expectant mothers and healthcare professionals. By benefiting from the relaxing effect of warm water, this method aims to make the birth process more comfortable. Although it is often associated with the concept of “natural birth,” water birth requires thorough medical evaluation and specialist supervision. When proper patient selection is not ensured, water birth can shift from being an advantage to becoming a risk factor.

In the first part of this article series, what water birth is, how it is performed, and its physiological foundations are discussed in detail. The second part addresses the advantages of water birth, eligibility criteria, risks, and necessary precautions.

What Is Water Birth?

Water birth is a delivery method based on conducting the active phase of labor—or the entire birth process—in a specially designed birthing pool or tub that meets specific standards. In this method, the expectant mother enters warm water during the phase when contractions intensify, and labor progresses in this environment. In some practices, only the contraction phase takes place in water, while in others, the baby is born in the water.

In obstetrics and gynecology literature, water birth is classified as a “supportive birth method.” This means it is not an independent type of birth on its own but rather an approach that supports the normal vaginal birth process under certain conditions. Therefore, it is not compared to cesarean delivery; instead, it is considered a variation of normal birth.

The buoyancy of water partially reduces the mother’s body weight, decreasing the load on the musculoskeletal system. This allows the mother to change positions more comfortably and take a more active role during labor. However, this physiological comfort is meaningful only when appropriate clinical conditions are met.

The Physiological Basis of Water Birth

The foundation of water birth lies in the neuromuscular effects of warm water on the human body. When immersed in water, the parasympathetic nervous system becomes more dominant, resulting in muscle relaxation, regulation of heart rate, and a reduction in stress hormones. A decrease in adrenaline and cortisol levels—both of which play a role in the perception of labor pain—may help the mother tolerate the birth process more easily.

In obstetrics and gynecology practice, the progression of labor depends not only on regular uterine contractions but also on the mother’s ability to relax. Excessive stress and fear can disrupt contraction patterns and prolong labor. The relaxation provided by warm water may therefore play a supportive role in maintaining the physiological flow of birth.

Nevertheless, the positive effects of water are not experienced at the same level by every expectant mother. Pain perception, psychological preparedness, previous birth experiences, and individual expectations are factors that directly influence the benefits obtained from water birth.

How Is Water Birth Performed?

Water birth is not a decision made suddenly once labor begins. The process is planned through a detailed evaluation conducted in the later weeks of pregnancy. An obstetrics and gynecology specialist carefully reviews the mother’s general health status, the course of pregnancy, and potential risk factors. Based on this assessment, a decision is made regarding whether water birth is appropriate.

During labor, the water temperature is generally maintained between 36–37°C. This range is close to the mother’s body temperature and helps prevent sudden temperature changes. The mother may sit, kneel, or assume supported squatting positions in the water. This flexibility can help the pelvic opening adapt more easily during labor.

Throughout the process, the heart rates of both the mother and the baby are monitored regularly. If a risky situation arises at any stage of labor, the mother is removed from the water and delivery continues according to standard vaginal birth protocols. For this reason, facilities offering water birth must be fully equipped for emergency intervention.

Differences Between Water Birth and Vaginal Birth

Water birth is fundamentally based on the physiological principles of vaginal birth but differs in terms of the environment in which it is performed. In vaginal birth, the mother typically gives birth on a bed or in limited positions, whereas water birth offers a wider range of movement. This can enhance the mother’s active participation in the birth process.

However, this difference does not mean that water birth is always better or easier. With proper support, appropriate positioning, and conscious birth preparation, similar levels of comfort can also be achieved in vaginal birth. Therefore, obstetrics and gynecology specialists do not consider water birth a method suitable for everyone, but rather an option for pregnancies that meet specific criteria.

What Are the Advantages of Water Birth?

The advantages of water birth extend beyond the simple notion of “less pain.” In obstetrics and gynecology, this method is viewed as an environmental factor that supports the physiological flow of labor. Warm water can reduce the body’s stress response during childbirth, helping the mother feel calmer and more in control.

Muscle relaxation—particularly in the pelvic floor muscles—may contribute to better coordination during labor. This can facilitate the opening of the birth canal and allow labor to progress more smoothly in some cases. Additionally, the buoyancy of water reduces physical fatigue during prolonged contraction phases by alleviating body weight.

From a psychological perspective, some women who experience water birth report feeling safer and more like the “active agent” of their birth experience. This sense of control may reduce the risk of perceiving childbirth as traumatic. However, it should be noted that these benefits depend on individual differences and may not occur in every mother.

Who Is Suitable for Water Birth?

For water birth to be a safe option, certain clinical criteria must be met. These criteria are established in accordance with obstetrics and gynecology guidelines aimed at protecting the health of both mother and baby. The most fundamental requirement is that the pregnancy follows a low-risk course.

Completing the 37th week of pregnancy, having the baby in a head-down position, and experiencing no major complications during pregnancy are generally considered favorable factors for water birth. Normal blood pressure, blood sugar levels, and absence of infection are also important considerations.

In addition, the mother must be consciously prepared for the birth process. Since water birth requires active participation, the mother should genuinely want this method and feel ready to manage her body and the process during labor. This preparation should be supported by prenatal education and specialist consultations.

What Are the Contraindications for Water Birth?

Although water birth may offer advantages in some pregnancies, it is strictly not recommended in certain situations. These contraindications are typically associated with clinical conditions that may pose risks to the mother or baby. Obstetrics and gynecology specialists advise avoiding water birth in such cases.

High blood pressure during pregnancy, preeclampsia, gestational diabetes, multiple pregnancies, or risk of preterm labor are contraindications for water birth. Additionally, breech presentation, detected irregularities in fetal heart rate, or the presence of meconium-stained amniotic fluid during labor also limit the use of this method.

Active infections, a high risk of bleeding, or severe anemia in the mother are also considered risk factors for water birth. In such cases, conducting the delivery in a hospital setting using standard protocols is generally regarded as safer for both mother and baby.

What Are the Risks of Water Birth?

Although water birth is generally considered safe, it is not entirely risk-free. Risks are most often associated with improper patient selection or inadequate medical monitoring. Therefore, potential risks should be clearly explained to the expectant mother before delivery.

For the baby, rare risks such as water aspiration, delayed respiratory adaptation after birth, or infection have been reported. For the mother, potential complications include prolonged labor, sudden bleeding, or infection. These situations may require immediate intervention during childbirth.

In obstetrics and gynecology practice, the key priority is the early recognition of these risks and the prompt change of delivery method when necessary. For this reason, facilities offering water birth must be fully prepared for emergency care.

Precautions to Be Taken During Water Birth

The safe implementation of water birth is directly related to the precautions taken. These measures aim to protect the health of both mother and baby, with hygiene being the most fundamental requirement.

The birthing pool must be regularly sterilized, and the cleanliness and temperature of the water must be continuously monitored. The heart rate, blood pressure, and general condition of both mother and baby should be observed throughout labor. The birth team must be prepared to respond to potential complications.

Additionally, it is crucial that the obstetrics and gynecology team managing the birth has experience with water birth. This expertise ensures the process progresses safely and that appropriate decisions are made quickly when needed.
