Rising heat poses serious risks to pregnant women, newborns: UN

Soaring temperatures are creating mounting health hazards for pregnant women and newborns, with nearly three-quarters of maternal health practitioners reporting a surge in heat-linked cases and complications, according to findings presented by United Nations climate officials.

The data, which includes responses from medical professionals across India and neighbouring regions, underscores the direct link between climate change and maternal health outcomes. Heat stress during pregnancy can trigger premature labour, low birth weight, and other serious complications, while newborns face heightened risks of heat-related illness and dehydration.

Maternal health professionals working in frontline settings have documented rising incidence of heat exhaustion, dehydration, and pregnancy-related complications during periods of extreme temperature. The findings highlight particular vulnerabilities in South Asia, where populations face increasingly intense and prolonged heat waves.

UN climate authorities have emphasised the urgent need for targeted interventions to protect pregnant women and infants during heat events. These include improved access to cooling centres, enhanced prenatal care during summer months, and public health measures specifically designed to shield vulnerable mothers and newborns from extreme heat exposure.

The convergence of climate change and maternal health challenges underscores the critical need for integrated approaches that address both environmental resilience and healthcare preparedness across the region.
