Pregnant women can be afraid of cold for the following reasons: first, there will be obvious changes in the endocrine function of women during pregnancy, for example, the endocrine function may decrease, which will lead to a decrease in the content of estrogen, sex hormones, progesterone and thyroid hormones in the body, resulting in a decrease in the metabolic function of women, and a weakened basal metabolic rate can also lead to a low body temperature of women, which eventually leads to women’s fear of cold; Secondly, women’s digestive function will be weakened during pregnancy, such as the digestion and absorption of sugar, fat and protein, which will be reduced, resulting in insufficient nutrient intake and a temporary decrease in energy supply, which can also lead to coldness in pregnant women; thirdly, the function of the nervous system of women during pregnancy will be relatively low, which can also lead to dysfunction of the regulation of the nervous system, thus This can lead to women’s fear of cold during pregnancy.
