The thought of soaking your body in the warmth of a sauna or hot tub may sound wonderful but may not be safe for baby.
Before you use hot sauna, know the risks to you and your baby-to-be. Extreme heat is the main concern with using a sauna or hot tub during pregnancy. While this heat may be relaxing and feel good, it may not be safe for your baby-to-be. When babies are in utero, they’re unable to regulate their body temperature. This means that they can’t tolerate the extreme heat of a sauna or hot tub.
High fever in early pregnancy is harmful for developing baby as it increases risk of miscarriage and birth defects like spinal cord and brain malformation. Thus, all treatments that raise your body temperature should be off limits during pregnancy. These include sauna, steam room and hot tub.
Warm baths are fine as long as not super hot, since water cools off fairly quickly.
