In The Gambia, where there is high humidity and direct sunlight, more than 90 subsistence farmers operate in rice fields, and they were observed by the study.
According to researchers from the London School of Hygiene and Tropical Medicine, each mother's unborn child's heart rate spiked to risky levels.
They discovered that as the mother's placenta was affected by the heat, the blood flow to the fetus slowed.
