Low-dose aspirin may offset premature birth risk linked to extreme heat

Mounting evidence links extreme heat to preterm (often called premature) birth, low birth weight, and stillbirth, indicating that rising temperatures are contributing to worse health outcomes for pregnant people and newborns. Preterm birth is already a leading cause of infant illness and death worldwide, with an estimated 12 to 15 million babies born too early each year, meaning even modest increases in heat-related risk could have substantial global consequences.
