The best thing a pregnant woman can do for herself during pregnancy is to find ways to relax and rest. One common method of relaxation is taking a comfortable bath. While soaking in hot water is a popular choice, many pregnant women wonder whether bathing in warm water is safe.
1. Can pregnant women take hot baths?
Pregnancy can be a beautiful period in a woman’s life, but it's not always easy to accept the physical changes it brings. In addition to the daily stressors, pregnancy hormones can significantly impact a woman’s body. From morning sickness to muscle aches and mood swings, many pregnant women may experience overwhelming stress. However, excessive and continuous stress can negatively affect the developing fetus as well as the mother’s health.
At this stage, any activity that helps a pregnant woman relax is encouraged. Finding time to rest, however, can be challenging, especially for those who continue working during pregnancy. Therefore, taking a warm bath is a great way to unwind at the end of a long day. Still, it is important to check the water temperature to ensure it’s not too hot. Exposure to excessively high temperatures can result in burns and may even harm the fetus.
2. Risks of hot baths during pregnancy
When bathing in hot water, body temperature rises. While this increase in temperature is generally not immediately dangerous, it can be risky during pregnancy. If a pregnant woman’s body temperature becomes too high, leading to hyperthermia, it could endanger the baby in the womb.
Excessive heat exposure can cause certain birth defects, particularly during the first trimester (the first 12 weeks) when the baby’s organs are forming. The brain and spinal cord are especially vulnerable to hyperthermia, increasing the risk of neural tube defects during this period.
Another issue with excessively hot water is that it can lower blood pressure. This reduction in blood pressure can affect blood flow from the mother to the fetus and may pose risks at any stage of pregnancy. Initially, the mother may feel lightheaded, dizzy, or even nauseous. In severe cases, low blood pressure increases the risk of fainting and falling, which could lead to injury.
Additionally, caution is advised when visiting hot spas or saunas. Even without direct contact with hot water, the risk of overheating remains, and it may even be higher in these environments. This is because, while bathing, the water gradually cools down, whereas spas and saunas maintain consistently high temperatures.
This is why saunas, steam rooms, and hot tubs are considered unsafe during pregnancy. Pregnant women can take warm baths, but they should avoid bathing in water that is too hot or for prolonged periods.
Some mothers worry that bathwater might enter the uterus and harm the developing fetus. Fortunately, the baby is well-protected inside the amniotic sac. Unless the water breaks, the baby remains completely isolated from external bathwater.
3. Safe Choices for Hot Baths During Pregnancy
In general, healthcare experts advise pregnant women to avoid spas, saunas, and hot baths. However, pregnant women can still bathe as long as the water is not too hot. It’s recommended to avoid soaking in hot water that could raise body temperature above 39°C (102.2°F) for more than 10 minutes.
That said, there are no specific limits on how long or how hot an environment can be safely tolerated by pregnant women. Therefore, before getting into a bath, check the water temperature using your elbow or forearm, as these areas are more sensitive to heat and can provide a better estimate. The water should be warm enough to relieve stress and relax muscles, but if you notice redness or sweating, it might indicate the water is too hot.
The most accurate method is to use a thermometer to check the water temperature or a baby bath thermometer to monitor it throughout the bath. If the water is too hot, it’s best to exit the bath quickly or adjust the water heater to maintain a lower, safer temperature during pregnancy.
In summary, hot baths can be a great way to soothe sore muscles and relax during pregnancy. The key to safely enjoying hot baths while pregnant is to keep the water at a warm—not too hot—temperature and take precautions when entering the bath. Additionally, pregnant women should ensure they follow all necessary safety measures so that bathing remains a safe and healthy activity for both mother and baby throughout pregnancy.
