WARREN COUNTY, OH -- With summer temperatures sure to rise in the coming weeks across the region, clinicians at Mercy Health’s Anderson Family Birthing Center are reminding expectant mothers that summer heat can bring added challenges during pregnancy, and offering practical guidance to stay safe and comfortable.

“During pregnancy, a woman’s body is already working harder, and that can make warm weather feel even more intense,” said Katherine M Frizzell, APRN-CNM, a certified nurse-midwife at Mercy Health – Anderson Family Birthing Center. “We see many moms who are surprised by how quickly dehydration and swelling can set in during the summer months.”

Pregnancy naturally increases blood volume and dilates blood vessels, which can make women feel warmer than usual. Combined with heat and humidity, these changes can lead to common side effects such as swelling, fatigue, dehydration, and increased sensitivity to the sun.

According to Mercy Health providers, swelling in the feet and ankles can become more noticeable in warmer months due to changes in fluid balance and the added pressure from a growing uterus.

To help reduce discomfort and stay healthy, clinicians at the Anderson Family Birthing Center recommend a few simple but important steps:

Stay well hydrated throughout the day, even before feeling thirsty
Take breaks in air-conditioned spaces or shaded areas
Avoid standing for long periods and elevate your feet when possible
Wear loose, lightweight clothing
Maintain gentle physical activity, such as walking, with proper hydration

“Hydration is one of the most important things we talk about with our patients,” Frizzell said. “When you’re pregnant, you need more fluids than you might expect, especially if you’re spending time outdoors. Dehydration can lead to dizziness, fatigue, and even contractions later in pregnancy.”

In addition to staying hydrated, Mercy Health experts encourage pregnant women to recognize the signs of heat exhaustion, which can include headache, nausea, muscle cramps, dizziness, rapid pulse, and excessive thirst.

“If those symptoms start, it’s important to get out of the heat right away, cool down, and drink fluids,” Frizzell said. “If symptoms don’t improve, it’s always best to call your provider.”

Clinicians also emphasize the importance of sun protection during pregnancy. Hormonal changes can make skin more sensitive and prone to discoloration, making sunscreen and shade especially important.

Beyond immediate comfort, managing heat exposure is also important for a baby’s development, particularly early in pregnancy.

“The early weeks of pregnancy are a critical time for development,” Frizzell added. “Avoiding excessive heat, staying hydrated, and keeping your body temperature regulated helps support both mom and baby.”
