What causes cold and sweaty hands and feet?

Some of our friends have cold hands and feet and excessive sweating in life. This symptom is often caused by kidney deficiency. In addition to kidney deficiency, there are some other causes that may lead to such symptoms, such as weak spleen and stomach, mental factors, etc. Everyone should do a good examination before undergoing treatment.

What causes cold and sweaty hands and feet?

1. Caused by Kidney Yang Deficiency

Cold hands and feet and sweating may be caused by kidney yang deficiency, weak defense, and dysfunction of warming the body! Yang deficiency and dysfunction of warming the body will cause symptoms such as cold hands and feet! Yang deficiency and weak defense will cause sweating easily! It is recommended to take yang-tonifying and qi-invigorating medicines under the guidance of a doctor, avoid eating spicy and irritating foods, drink more boiled water, and maintain a regular life.

2. Caused by weak spleen and stomach

According to Chinese medicine experts, cold hands and feet and sweating are mostly caused by weak spleen and stomach, yin deficiency and blood heat. If you eat too much fatty and sweet food and have an irregular diet, it may lead to weak spleen and stomach. When the spleen and stomach functions weaken, dampness and heat will accumulate in the body. Dampness and heat tend to move downward, causing sweating in the hands and feet. The main reason for cold hands and feet is that in winter, the human heart is weak and cannot supply blood to the extremities of the body, resulting in cold hands and feet.

3. Poor peripheral circulation

Cold hands and feet and excessive sweating are related to poor peripheral circulation. On the one hand, less arterial blood reaches the extremities (specifically hands and feet), and the amount of nutrients and oxygen it carries is less, causing the metabolism of this part of the body's tissue to be greatly reduced and heat production to be less, resulting in cold hands and feet. On the other hand, venous blood return is obstructed, and a considerable portion of metabolites produced by the limbs cannot be carried to the kidneys for metabolism with the blood circulation, and have to be excreted from the body through the sweat glands, resulting in cold sweat. This is due to physical condition. It can be improved by doing more exercise and also pay attention to keeping warm.

4. Mental factors

Mental factors can also cause cold and sweaty hands and feet, such as tension, fear, etc. Endocrine disorders can also cause excessive sweating of hands and feet. People with hyperhidrosis of the hands and feet often also have cold hands and feet. Especially in winter, when the outside temperature is much lower than body temperature (36℃～37℃), the body's temperature regulation function will be significantly reduced. In addition, the evaporation of sweat itself will also take away some heat. Therefore, people with hyperhidrosis will have noticeably colder hands and feet than normal people.
