Prolonged Exposure to Extreme Heat Can Be Dangerous for Expecting Mothers

High heat conditions can be dangerous for expecting mothers.

Pregnant women often have a higher body temperature because of progesterone and the warmth of the baby, making them more prone to the effects of extreme heat. It can increase the chances of birth defects, pre-eclampsia, gestational diabetes and even preterm labor.

According to Janna Mudd, M.D., an OB/GYN with Hoffman and Associates OB/GYN, an all-female practice affiliated with The Family Childbirth and Children's Center at Mercy, there are warning signs to pay attention to.

"They might start to notice that they're sweating a lot, so they want to definitely replace their electrolytes if they're sweating excessively. Their skin might become hot to the touch, they might become tired, they might experience muscle cramps or even uterine contractions. Those can all be signs to get inside and get cool," Dr. Mudd said.

Most pregnant women are fine going inside, cooling off and getting hydrated, Dr. Mudd added.

If they feel excessively tired, confused, short of breath or have a rapid heart rate, call the doctor or head to the emergency department.
