The Impact of Extreme Heat on Pregnancy: A Personal Perspective

As a soon-to-be mother and healthcare professional, I find myself increasingly concerned about the impact of extreme heat on my health and that of my unborn child. While waiting for my COVID-19 vaccination, I felt a mix of gratitude and anxiety, knowing I was just five weeks pregnant. My partner and I decided that getting vaccinated was the best decision for us, despite the limited data on its effects during pregnancy. Now, after receiving both doses, I’m relieved to say that both my baby and I are doing well, especially in light of the Delta variant.

The Rising Threat of Excessive Heat

However, as summer temperatures rise, another pressing health issue emerges: excessive heat. I’ve noticed that I have to plan my outdoor walks earlier in the day, and the time frame for safe outdoor activity is shrinking. This trend is alarming, given that the last decade has been the hottest on record, and scientists expect the frequency of dangerously high temperatures to increase in the coming years.

While some may dismiss climate change as a natural cycle, experts worldwide agree that human-induced greenhouse gas emissions are significantly responsible for rising temperatures. The increase in gases like carbon dioxide has caused our planet to absorb twice as much heat compared to just fifteen years ago, leading to more extreme weather conditions and heatwaves.

Health Risks for Pregnant Individuals

For pregnant individuals like me, these heatwaves can pose serious health risks. Pregnancy naturally raises body temperature, and reaching 102.2 degrees Fahrenheit increases the risk for heat-related illnesses such as heat stroke, dehydration, and heat exhaustion. Such dehydration can restrict blood flow to the placenta, potentially depriving the fetus of essential nutrients and even triggering premature labor.

Research indicates that high outdoor temperatures can increase the risk of premature birth by up to 21 percent. Moreover, for every degree Celsius increase in temperature during the week before delivery, there is a 6 percent higher chance of stillbirth during the warmer months. Extreme heat is also linked to low birth weight and congenital heart defects.

Disparities in Health Risks

These dangers disproportionately affect communities of color. Black pregnant individuals already face a higher risk of preterm birth and low birth weight, and exposure to extreme heat worsens these disparities. Structural inequalities, such as living in urban heat islands with limited green spaces and inadequate access to air conditioning, exacerbate these issues. Many residents in these areas struggle to afford the higher electricity costs associated with cooling their homes.

Taking Action Against Climate Change

To safeguard pregnant individuals and their babies, comprehensive and equitable action against climate change is essential. Creating green spaces can help mitigate extreme heat, but it’s crucial that these plans address the specific needs of marginalized communities. Energy efficiency programs must consider the unique challenges faced by vulnerable populations. Legislative efforts, like the Bipartisan Infrastructure Framework and the Protecting Moms and Babies Against Climate Change Act, aim to tackle the environmental health injustices that contribute to maternal mortality.

Looking Ahead

As I prepare to welcome my child into the world, I am acutely aware of the challenges posed by extreme heat. I hope for a future where real climate action creates a safe and healthy environment for all children to thrive.

In summary, as an expectant mom and physician, I am deeply concerned about the effects of rising temperatures on both my health and my baby’s well-being. The growing prevalence of extreme heat poses significant risks, especially for marginalized communities. It is imperative that we take urgent action to address climate change and protect future generations.
