What are the dangers of cold hands and feet when sleeping?

With the arrival of autumn and winter, some women will have cold hands and feet, and some are very afraid of cold. First of all, this is mostly related to the cold constitution of these women. This kind of physical condition is very harmful to health. Cold hands and feet often indicate that a woman's immunity is not good, and her endocrine system is sometimes out of balance. Therefore, women should do corresponding conditioning work at this time. Let's take a closer look at this aspect.

1. Caused by hormonal changes in women's bodies. Certain hormonal changes caused by women's menstrual period and childbirth can lead to constriction of subcutaneous blood vessels and a decrease in blood flow, which in turn causes cold hands and feet.

2. Iron deficiency. Studies have shown that people with low tolerance to cold have insufficient iron in their blood and are often accompanied by decreased plasma thyroid hormone. Iron deficiency in women is mainly caused by menstruation. When iron is deficient, the human body has less hemoglobin, which affects the blood's oxygen-carrying capacity, leading to disorders in tissue energy metabolism and insufficient heat generation, causing the body to feel cold.

3. Or heart function declines. Cold hands and feet are closely related to heart function, because blood is sent by the heart, carrying oxygen to all parts of the body. Only after sugar is oxidized can heat energy be generated, and hands and feet will be warm. Once heart function declines, blood circulation will be affected, causing cold hands and feet. For example, a weak heart can lead to a significant reduction in blood supply to the extremities of the body, causing the extremities to cool down.

4. Vascular disease. Some vascular diseases, such as Raynaud's disease and Takayasu arteritis, which are common in young women, and thromboangiitis obliterans, which is more common in middle-aged men, can affect the blood supply to the extremities of the human body.

5. Insufficient secretion of thyroid hormone. However, when the body's thyroid hormone secretion is insufficient, blood circulation in the skin and other parts of the body slows down, heat production is insufficient, and the body becomes more sensitive to cold.

From the above descriptions of hazards, it can be seen that women with cold hands and feet should take good care of themselves. First of all, they should pay attention to their diet, eat more warming foods, and avoid eating cold foods. This is something that needs attention. If possible, you can also take some tonic Chinese medicine to gradually improve the cold constitution. At the same time, you should also participate in moderate physical exercise.
