Understanding the Impact of Extreme Heat on Pregnant Women

Summary:
As the U.S. braces for a severe summer, medical experts express growing concerns about the impact of extreme heat on pregnant women, one of the most vulnerable groups. A study highlighted that between 1993 and 2017, over 2 million preterm births and nearly 6 million early-term births were linked to heatwaves. Extreme heat exacerbates the already high demands on a pregnant woman’s circulatory system, increasing risks of low birth weight, stillbirth, and preterm labor. Dehydration from sweating can lead to false labor contractions, and high overnight temperatures further elevate preterm birth risks.
Particularly at risk are Black women and other women of color, who face greater maternal health challenges due to economic and racial disparities. Studies indicate that these women, even those with higher education, are more susceptible to preterm births during heatwaves. The article stresses the compounded pressures on their bodies due to systemic disadvantages like poor housing and limited access to air conditioning.
To mitigate these risks, the article advises pregnant women to stay well-hydrated, cool down in the evenings with showers or soaking feet in cool water, and prioritize air conditioning in bedrooms to ensure overnight recovery from heat.
