It’s safe to take baths while you’re pregnant as long as the water temperature does not exceed 100 degrees Fahrenheit. Avoid soaking in water hot enough to raise your body temperature above 102.2 degrees Fahrenheit (39 degrees Celsius).
High temperatures, particularly early in pregnancy, have been linked to an increased risk of neural tube defects. This is why saunas, steam baths, and hot tubs are not recommended during pregnancy.
It’s unlikely that you would run a bath hot enough to pose a risk to your baby. However, to be safe, test the water temperature with your forearm or wrist before getting in; it should feel comfortable, not burning hot. If you’re concerned, you can also use a bath thermometer to check the water temperature.
Some expectant mothers worry that bath water might enter the uterus and harm their developing baby. Fortunately, your baby is protected within your uterus, cervix, and the amniotic sac. Unless your water breaks, your baby is completely separated from the water you’re soaking in. In fact, tubs can be used during labor to help ease labor pains. (After your water breaks, taking a bath at home is not recommended due to the risk of infection.)
A bath is an excellent way to soothe sore muscles and reduce stress during pregnancy. Just ensure the water is warm, not hot, and be careful when stepping in and out of the tub. Your center of gravity can shift during pregnancy, which might affect your balance.
