{"id":"1793530890405-mix-segment","slug":"heat-and-pregnancy-risk","title":"Heat and pregnancy risk","summary":"A Reuters investigation and multiple peer-reviewed studies show that higher ambient heat during pregnancy is linked to increased stillbirth risk. A 2024 meta-analysis in Nature Medicine found the odds of stillbirth rise by about 13% during high heat exposure and by 14% per 1°C increase in some U.S. studies. A 2022 study of six U.S. states found that four consecutive hot days in the prior week raised stillbirth risk by 3%, and a 1°C average increase above the local threshold raised risk by 10%.\n\nHeat exposure can reduce placental blood flow, cause congenital anomalies, and trigger epigenetic changes. Risks are higher for women in lower socioeconomic groups, at age extremes, and among Black mothers. Climate change is increasing the frequency and intensity of heatwaves, making this a growing public health threat.\n\nA 1°C (1.8°F) increase in average heat exposure during pregnancy is associated with a significantly higher risk of stillbirth. Meta-analyses report odds increases of roughly 5–14% per 1°C, with stronger effects during heatwaves.\n\nHanwha Ocean, the shipbuilding arm of South Korea's Hanwha Group, signed a $269 million contract with the U.S. Navy for maintenance, repair and overhaul work. This is political commentary and sarcasm about Netanyahu, Qatar and Arab voter turnout. No factual claim requiring verification. Opinion piece arguing Israel does not have to fight on seven fronts and that Arab citizens could help guard borders. No checkable factual claim.\n\nThere is no credible report of 35,000 Vietnamese Democrats and 20,000 undecided voters voting for Steve Hilton in California. Steve Hilton is a conservative political commentator and former Fox News host, not a candidate on any California ballot. Opinion/argument about Israeli Arab citizens and the political right.
