Fear of heat in late pregnancy is caused by the vigorous metabolism and more body heat during pregnancy. In late pregnancy, estrogen and placental hormones are secreted vigorously, resulting in vigorous metabolism and the production of more heat, which can easily lead to an increase in body temperature of pregnant women, who are more afraid of heat compared to ordinary people. In order to minimize the discomfort of pregnant women, appropriate cooling measures can be taken, such as reducing clothing, fanning with a fan and so on. Pregnant women are advised to wear loose-fitting clothes and avoid staying in a hot environment for a long time to avoid heat stroke. It is important to note that pregnant women should seek timely medical attention if they feel unwell, so as to avoid adverse effects on the pregnant woman and the fetus. In addition, pregnant women should also pay attention to rest, do not stay up late, and eat a balanced diet.
