Heat waves are increasing in frequency and intensity, presenting a significant health risk globally. Studies have shown a connection between heat exposure and preterm delivery and stillbirth. A recent study in the US found that preterm births increased by 2% and early births by 1% after a heat wave. Vulnerable populations, including younger mothers, those with lower education levels, and minority groups, experienced higher rates of preterm and early births. The physiological mechanisms behind these outcomes are still unclear. The implications of climate change on pregnancy outcomes underscore the need for further research and understanding of the social and economic impacts.
