A Systematic Review and Meta-Analysis of Heat Exposure Impacts on Maternal, Fetal and Neonatal Health
- Climate Central released a report on May 19, 2025, showing that climate change has doubled pregnancy heat-risk days globally from 2020 to 2024, including in India and the U.S.
- The increase in pregnancy heat-risk days results from rising extreme heat events linked to human-caused fossil fuel emissions, which raise maximum temperatures beyond historical 95th percentiles.
- Higher heat-risk days associate with increased complications during pregnancy, such as preterm birth, gestational diabetes, hypertension, and stillbirth, especially in regions with limited healthcare access.
- Dr. Bruce Bekkar said, "Extreme heat is pushing more pregnancies into high-risk territory," highlighting this danger particularly for vulnerable populations struggling with healthcare shortages.
- The findings underscore the urgent need to cut fossil fuel emissions and adopt local policies mitigating heat exposure to protect maternal and newborn health worldwide.

A systematic review and meta-analysis of heat exposure impacts on maternal, fetal and neonatal health
Climate change has severe and wide-ranging health impacts, especially for vulnerable groups. Despite growing evidence of heat-associated adverse maternal and neonatal health outcomes, there remains a lack of synthesis quantifying associations and identifying specific risk periods. We systematically reviewed the literature on heat impacts on maternal, fetal and neonatal health and quantified impacts through meta-analyses. We found 198 studies acr…
