- The difference in forehead and sole temperatures was 2.0°C among Japanese and 2.8°C among Brazilians in June-July.
- In November, the temperature difference was 5.2°C among Japanese and 2.8°C among Brazilians.
Takeaway
This study found that more Japanese pregnant women know about feeling cold than Brazilian pregnant women, and their body temperatures are different too.
