What reason is cold before sleeping

summary

Speaking of the fear of cold before going to bed, we should not feel very strange. Iron deficiency and insufficient thyroid hormone secretion are important reasons for women's fear of cold. In any case, we have to understand that women should take 18 mg of iron a day mainly because of menstruation, but most women do not meet this requirement, so they are afraid of cold. I'll tell you why I'm afraid of cold before I go to bed.

What reason is cold before sleeping

First, the cause of the disease is the slow operation of the autonomic nerve and the poor blood circulation of the hands, feet and waist with less blood vessels. In addition, hormone secretion disorders, metabolic decline can also lead to such symptoms.

Second: the biggest culprit of cold phobia is the air conditioning in the office. Although the power supply is tight, many units will adjust the air conditioning temperature very low. Women have been in the air-conditioned room for a long time and can't resist the temptation of ice cream, iced coffee, cake sweets and Nanyang fruits; they are greedy for cool clothes and often go to battle with sleeveless tops and shorts and skirts, which are all the factors causing chills.

Third: modern medicine believes that women because of the high content of estrogen in the body, the body's heat is easy to convert into fat stored in the subcutaneous. And the metabolic rate is lower than men, the synthesis of heat is greater than decomposition, so that the body heat release is less.

matters needing attention

Iron deficiency and insufficient thyroid hormone secretion are also important reasons for women's fear of cold. American weight scientists and nutritionists test results show that: those with low cold tolerance, blood iron content is insufficient, and often accompanied by a decrease in plasma thyroxine. Women lose iron mainly because of menstruation. Nutritionists point out that women should take 18 mg of iron a day, but most women do not meet this requirement and are 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 the heat. And when thyroxine secretion insufficiency, because produces the heat to be few, therefore is afraid of the cold.
