Extreme heat poses growing health threat to pregnant women, newborns

Pregnant women and newborns face escalating health dangers from extreme heat events, UN climate leadership has cautioned, linking the phenomenon directly to ongoing global temperature rises. Medical complications associated with prolonged heat exposure in these vulnerable groups have become a growing concern for health systems worldwide.

The risks are particularly acute during pregnancy, when women's bodies undergo significant physiological changes that reduce heat tolerance. Expectant mothers face elevated risks of dehydration, heat exhaustion, and complications that can affect fetal development. Newborns and infants similarly struggle to regulate body temperature effectively, making them susceptible to heat-related illness during extreme weather events.

The warnings underscore how climate change extends beyond environmental concerns to directly impact public health outcomes. Regions experiencing more frequent and intense heat waves are reporting increased cases of heat-related complications among pregnant women and young children, straining healthcare resources.

Health authorities have urged enhanced monitoring systems and targeted interventions to protect these demographic groups during heat emergencies. The issue has become particularly relevant in South and Southeast Asia, where rising temperatures and growing populations intensify the challenge. Experts emphasize that climate adaptation strategies must prioritize maternal and infant health protections to mitigate risks as extreme weather becomes more commonplace.
