Why is my girlfriend so cold when she sleeps at night?

Modern medicine believes that because of the high estrogen content in the body, women’s body heat is easily converted into fat and stored under the skin. Moreover, the metabolic rate is lower than that of men, and the synthesis of heat is greater than the decomposition of heat, thus reducing the amount of heat in the body. The release of heat is less. In addition, women generally do not like exercise, so the heat production will be less. Due to insufficient exercise, it often causes poor systemic or local circulation, leading to coldness throughout the body, especially in peripheral parts such as hands and feet. Feeling cold.

In addition, iron deficiency and insufficient thyroid hormone secretion are also important reasons why women are afraid of cold. Experimental results by American physiological scientists and nutritionists have proven that those with low cold tolerance have lower levels of iron in their blood. Insufficient content of elements is often accompanied by a decrease in thyroxine in plasma. Women mainly lose iron due to menstruation. Nutritionists point out that women should consume 18 mg of iron daily, but most women do not meet this requirement and are therefore afraid of Cold. Thyroid hormone has a "heat-generating" effect, which can increase the body's basal metabolism, speed up blood circulation in the skin, and increase heat. When thyroxine is not secreted enough, it produces less heat, so it is afraid of cold.
