Heat-Related Pregnancy Complications Pose Increased Risk for Pregnant Women, Study Finds
New research published in the Journal of the American Medical Association (JAMA) has shed light on the heightened risk of heat-related complications during pregnancy. According to the study, exposure to prolonged high temperatures, defined as reaching 95 degrees Fahrenheit or higher for three or more consecutive days, can increase the risk of pregnancy complications such as sepsis, hemorrhage, and clotting disorders by up to 27%.
The study, which focused on over 400,000 pregnancies in Southern California, found that heat exposure during the final week of pregnancy significantly increased the risk of life-threatening delivery complications. Additionally, heat exposure during the last trimester was identified as a risk factor for “severe maternal morbidity.”
These findings hold particular significance as the United States experiences record-high temperatures, with 19 states currently on alert for extreme heat. The study notes that pregnant women already exert more effort to cool both their own bodies and their developing babies, making them more susceptible to heat-related illnesses.
Furthermore, a previous study published in 2020 suggests that heat exposure may have contributed to an estimated 25,000 premature births per year between 1969 and 1988. This underscores the urgent need to address heat-related risks for pregnant women.
To mitigate these risks, experts recommend that pregnant women limit their time spent outdoors during extreme temperatures and seek shelter in air-conditioned environments. Additionally, the use of ice packs can help cool the body and alleviate heat-related symptoms. It is crucial for pregnant individuals to be aware of the signs of heat exhaustion, which include nausea, vomiting, fatigue, and dizziness. If left untreated, heat exhaustion can progress to heat stroke, characterized by a temperature of 103 degrees or higher, loss of sweat production, confusion, and loss of consciousness.
In the event of heat stroke, pregnant individuals are advised to seek immediate medical treatment in the emergency room. Prompt action can help prevent further complications and ensure the well-being of both the mother and baby.
As the threat of extreme heat persists, it is important for pregnant women and healthcare professionals alike to be informed about the increased risks and take appropriate measures to ensure a safe and healthy pregnancy.
