Mitigating the Impact of Heat Exposure on Black Maternal Health

We’ve all seen the record heat gripping many areas of the U.S. lately. High temperatures can be deadly and greatly impact the health and well-being of those most at risk.  Pregnancy naturally elevates the body’s temperature. As such, pregnant women are among the most vulnerable to extreme temperatures. Black pregnant women in particular face an increased risk primarily due to healthcare inequities and a greater likelihood of residing in heat-prone areas.

The Impact of Heat on Maternal Health

Extreme temperatures can exacerbate heat-related health issues such as dehydration, heat exhaustion, and even heatstroke, which can have serious implications for both maternal and fetal health.

Heat exposure during pregnancy is also linked to other adverse outcomes, especially for women of color, including:

• Increased risk of preterm birth: High temperatures can induce premature labor, possibly due to the body’s stress response or dehydration. Research has shown that, compared to White women, Black and Latina women with heat exposure had double or more the risk of preterm birth or stillbirth.
• Low birth weight: Exposure to excessive heat during pregnancy has been correlated with a higher incidence of babies born with low birth weight, a factor associated with numerous developmental issues.
• Gestational hypertension: Pregnant women exposed to high temperatures may experience elevated blood pressure levels, contributing to complications such as preeclampsia.

Avoiding or Reducing the Risk of Heat Exposure

Given the significant risk to maternal health, reducing or avoiding heat exposure is crucial to maintaining good maternal health, especially for pregnant mothers of color. Here’s how you can reduce the risk to the health of you and your baby this summer:

Stay Hydrated

Drink plenty of water throughout the day to prevent dehydration.

Seek Shade and Cool Environments

Whenever possible, stay indoors in air-conditioned environments during peak heat hours. If air conditioning is not available, spending time in public spaces such as libraries, shopping malls, or local established cooling centers can provide relief.

Wear Appropriate Clothing

Light-colored, loose-fitting clothing made of breathable fabrics can help keep the body cool.

Plan Outdoor Activities Wisely

Limit outdoor activities to cooler parts of the day, such as early morning or late evening. When outside, use a sun hat and sunscreen to protect against UV rays.

Use Cooling Products

Items like cooling towels or misting fans can provide great temporary relief when outdoors.

Monitor Health Closely

Be aware of the signs of heat-related illnesses, such as excessive sweating, dizziness, fainting, and fatigue. If you experience these symptoms, seek medical attention promptly.

Taking these precautions to avoid the effects of extreme heat can help protect Black maternal health, ensuring a safer, healthier future for mother and baby
