The causes of cold feet usually include poor physical condition, anemia, arteriosclerosis of the lower limbs, hypothyroidism, etc., which require timely medical treatment. 1. Lack of physical exercise for a long period of time may lead to abnormal physical condition, poor cold tolerance, poor circulation of blood in the extremities, etc., which may result in cold soles of the feet. 2. Long-term chronic blood loss or long-term malnutrition may cause anemia, which in turn leads to slower metabolism and reduced heat production in the tissue cells of the soles of the feet, resulting in the phenomenon of cold soles of the feet. 3. Arteriosclerosis of the lower limbs may also affect the blood circulation of the soles of the feet, resulting in cold soles. 4. Hypothyroidism can also lead to a lack of thyroxine, which in turn affects metabolism and causes cold soles. If any of the above symptoms occur, you should go to the hospital for examination.
