First, a woman’s body temperature is also affected by estrogen levels, because estrogen can dilate blood vessels. At the beginning of a woman's menstrual cycle, the estrogen level is very high, the blood vessels dilate, and the blood circulation expands to the ends of the skin all over the body. At this time, the woman's body is warmer. On the contrary, when estrogen levels drop, blood vessels constrict and the blood circulation system retreats to the trunk, making the limbs feel cold.
Second, a woman’s body temperature is also affected by her diet. Many women diet excessively in order to maintain a slim figure, and the calories they take in from food are simply not enough to burn off. Especially in winter, to keep the body warm, each person must consume 100 more calories per day to meet the needs of body metabolism. Otherwise, once the metabolism in the body slows down, the body temperature will drop, and the woman will feel more "cold".
As for whether it is better to be like a man who is always warm, or like a woman who is always cold? American experts have different opinions. Some men are grateful that their metabolism is fast and their firepower is strong, and they can achieve quick results if they want to lose weight; some women are a bit "jealous" about this, but they can still comfort themselves. The reason is: if ladies and men are trapped in the vast forest and snowfield, the ladies retreat quickly because of their blood circulation system and consume less energy. They can persist for a few more minutes at the last moment of life, and may be saved. As for ladies who are usually cold, they can go to their husbands to keep warm - the heat emitted by their husbands is enough to keep their wives warm.
