Maternal health workers report rising heat-related pregnancy complications across five countries

A survey of 1,001 maternal healthcare workers in Australia, Brazil, India, and two other countries finds nearly three in four report increased heat-related complications in pregnant women over the past five years. The findings, released ahead of COP31, highlight a growing climate-health nexus but rely on self-reported perceptions rather than clinical data. This matters as it signals a potential strain on maternal health systems and adds pressure for climate adaptation measures.
