It's especially cold for my girlfriend to sleep at night. What happened?

Modern medicine believes that the heat in women's bodies is easily converted into fat and stored under the skin because of the high estrogen content, and the metabolic rate is lower than that of men. The synthesis of heat is greater than the decomposition, so less heat is released in the body. In addition, women generally don't like sports, so they generate less heat. Due to lack of exercise, it often leads to poor circulation in the whole body or local areas, leading to chills all over the body, especially in the peripheral parts such as hands and feet.

In addition, iron deficiency and insufficient thyroxine secretion are also important reasons why women are afraid of cold. The experimental results of American physiologists and nutritionists prove that people with low cold tolerance have insufficient iron content in their blood, which is often accompanied by the decrease of thyroxine in their plasma. Women lose iron mainly because of menstruation. Nutritionists point out that women should consume 65,438+08 mg of iron every day, but most women can't meet this requirement. Therefore, it is afraid of cold. Thyroxine has the function of "generating heat", which can increase the basic metabolism of human body, accelerate the blood circulation of skin and increase calories. However, when thyroid hormone secretion is insufficient, it is afraid of cold because of less heat production.

Measures:
