Why do I have cold hands and feet, why are my hands and feet so cold?

Therefore, it should be advocated to participate in more appropriate sports, eat and live in a regular and orderly manner, pay attention to warm and cold clothing, and do not eat raw and cold food.

There is also a kind of cold hands and feet, which is called "four reverses" in Chinese medicine. "Four" is the end of the limbs; "Reverse" means cold. This condition is because the blood circulation cannot reach the ends of the limbs, so the blood ** is insufficient, resulting in cold limbs.

Women are also prone to chills caused by anemia during special physiological periods, and people who have excessive blood loss due to gastrointestinal bleeding will also have anemia and chills. In addition, there is also a disease called "blood dryness" in traditional Chinese medicine, which is anemia and chills caused by the reduction of blood dryness, which is the need to replenish blood. If the blood is blocked, it is necessary to use the ** method of "breaking the blood congestion and generating new blood" to break the blood congestion and produce new blood, which is what we often hear about "activating blood and dissolving blood congestion".

What's the matter with "cold" hands and feet all the time? A lot of people don't care, and they end up suffering a big loss.

People with this condition are prone to spasm of the peripheral blood vessels, and when they encounter cold air or cold water, the blood vessels of the hands and feet will constrict, and the blood circulation will not be smooth, and the hands and feet will be easy to be cold and purple. In addition, it may also be due to poor sympathetic nerve function, which makes it impossible to tighten muscles in case of cold to produce heat and cold tolerance.

The human body temperature is maintained between 36 and 37 degrees Celsius, and when the human body's ** is exposed to the outside temperature, it will be directly transmitted to the life center of the brain to control breathing, heartbeat, body temperature, etc. When it is hot, the body temperature control center will innervate the sympathetic nerve to excite, so that the pores and sweat pores open to dissipate heat and sweat; When you feel cold, the sympathetic nerve will cause all parts of the limb, including the muscles near the teeth, to shiver, so that the muscles and fat cells will be tightened to produce heat energy to resist the cold, which is why people shiver when they feel cold.

People who smoke for a long time are prone to poor circulation due to insufficient oxygen in the body, and when the arterial microvessels are not smooth, they are prone to chills; However, if the vein microvessels are not smooth, although there is no special fear of cold, the blood vessels cannot be dilated during activity, and the blood cannot circulate, resulting in local oxygen insufficiency, and the hands and feet are prone to coldness.

Urban "lazy people" who usually "don't sit if they can lie down, and don't stand if they can sit", because of the decrease in basal metabolic rate, will also have the problem of not being cold-tolerant.

Women are afraid of the cold to make up some iron.

In general, women are more sensitive to cold than men. Not long ago, two experts from a human health research institute in the United States conducted a group experiment on female volunteers, and the experimental report found that for people with low cold tolerance, the blood iron content was obviously insufficient. The main cause of iron deficiency in women is menstruation, which leads to a large loss of iron.

As we all know, iron is an important raw material for the production of hemoglobin, which is the main functional substance in red blood cells and is responsible for the transport and metabolism of oxygen in the body. Iodine and tyrosine are the main raw materials for the production of thyroxine, iodine needs to be continuously ingested from food, and tyrosine is generally synthesized in the body. Long-term iodine deficiency will affect the synthesis of thyroxine, and the body's ability to withstand the cold will also be reduced.
