Pregnancy heat study reveals how warmth and work impact mom and baby

This study looked at how heat and physical activity affect the health of pregnant women and their unborn babies. Twenty-four healthy women in late pregnancy completed four sessions of light or moderate walking in either a comfortable (20°C) or warm (30°C) room. Researchers measured the mother's temperature, heart rate, and hydration, and used ultrasound to check the baby's heart rate and blood flow. The goal was to understand how heat stress might impact both mother and baby.
