What is the reason for cold hands and feet in winter?

Cold hands and feet in winter is a normal physiological phenomenon, because the temperature drop will make blood vessels contract, and the blood reflux ability will be weakened, which will cause poor blood circulation of hands and feet, especially fingertips and toes, and poor peripheral nerve circulation.

Under normal circumstances, wearing more clothes, eating more warm food and exercising more can promote reflux and alleviate the problem of cold hands and feet. For people with weak vascular reflux ability and poor peripheral circulation, it is more difficult to warm their limbs in this way.

1.2, Yang deficiency constitution

People with cold hands and feet are mostly caused by yang deficiency constitution. If you still feel cold after buying warm clothes, you should pay attention to whether Chinese medicine has a constitution called' Yang deficiency'. "Yang deficiency" is also called deficiency cold. As the name implies, it refers to yang deficiency of human body, mostly spleen and kidney yang deficiency.

Yang is the foundation of life, and warming the body is one of its important functions. If the yang is insufficient, it will not be transported to the far ends of limbs and trunk, such as hands and feet, and there will be chills, cold hands and feet, etc. Therefore, an important way to relieve cold hands and feet is to recuperate the body and replenish "Yang".

1.3, iron deficiency

Studies have shown that people with low cold tolerance have insufficient iron content in blood, which is often accompanied by a decrease in plasma thyroxine. Iron deficiency in women mainly comes from menstruation. When iron is deficient, the human body will be afraid of cold because of the lack of heme, which will affect the oxygen carrying capacity of blood, leading to disorder of tissue energy metabolism and insufficient calories.

Cold hands and feet is not a disease.

Human skin can adjust the body surface temperature according to the change of external temperature, which is a self-protection mechanism of human body. Generally speaking, the temperature will be higher in summer. When the temperature drops, especially in cold winter, the skin will automatically close the capillaries, making blood flow to organs such as the heart, while the temperature of hands, feet, face and so on will drop, and even catch a cold or frostbite.

There is also a blood circulation disorder! The heart function declines, and blood cannot be supplied to the peripheral parts of the body. Anemia patients may have insufficient circulating blood and low hemoglobin or red blood cells. Poor peripheral circulation, some vascular diseases, such as arteriosclerosis, will make human blood vessels contract, weaken the ability of blood return, and lead to poor blood circulation in hands and feet, especially fingertips!
