Extreme Heat During Pregnancy Linked to Congenital Heart Defects

Significant association between higher temperatures during pregnancy and risk of newborn heart defects.

Heat Exposure Reduces Fetal Growth

Exposure to extreme heat, especially in the 2nd & 3rd trimesters, is consistently associated with lower mean birthweight in 624,000+ births.

Identifying Windows of Susceptibility

Work aims to identify specific gestational weeks when fetuses are most vulnerable to extreme temperatures for public health advice.

Building Climate-Resilient Cities

Future research is developing a Health Impact Assessment (HIA) tool to evaluate how urban development changes affect heat, greenness, and public health.
