Study reveals how heat and exercise impact pregnant women and fetuses
NCT ID NCT07326176
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how heat and physical activity affect the health of pregnant women and their unborn babies. Twenty-four healthy pregnant women completed four 3-hour sessions in a controlled room, either at a comfortable 20°C or a warm 30°C, while doing light or moderate treadmill walking. Researchers measured the mother's body temperature, heart rate, and the baby's heart rate and blood flow using ultrasound. The goal was to understand the body's response to heat and work during late pregnancy.
