One of the reasons: modern medicine believes that because of the high estrogen content in women, the heat in the body can easily be converted into fat and stored under the skin. Moreover, the metabolic rate is lower than that of men, and heat synthesis is greater than decomposition, so less heat is released in the body. In addition, women generally don't like activities and 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.

The second reason: iron deficiency and insufficient thyroxine secretion are also important reasons why women are afraid of cold. The experimental results of American weight scientists and nutritionists show that people with low cold tolerance have insufficient iron content in their blood, which is often accompanied by a decrease in thyroid hormone in their plasma. Women lose iron mainly because of menstruation. Nutritionists point out that women should consume 18 mg of iron every day, but most women can't meet this requirement, so they 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 calories. When thyroid hormone secretion is insufficient, people are afraid of cold because of less heat production.

In view of the above reasons, women who are afraid of cold should strengthen their ever-changing health care and take active and effective measures to enhance their cold resistance.

One of the measures: cold-resistant exercise. Starting from autumn, we should actively carry out cold-resistant exercise. Go to outdoor sports, such as walking, dancing and playing badminton. Wash your face and wipe your body with cold water every morning, or take a cold bath step by step.

Measure 2: Eat more foods rich in calories. Dog meat, beef and mutton are rich in fat and produce more calories, so you can eat more in moderation. It's better to stew for a long time.

Measure 3: Eat more foods rich in iron, such as animal liver, mutton, fish, eggs, black fungus, milk, beans, green leafy vegetables and so on.
