Sweating in the cold is often caused by a lack of yang qi. Yang has a warming effect, and a deficiency of Yang will lead to a weakening of the warming effect. Yang deficiency is often manifested as coldness, cold limbs, liking hot drinks, long and clear urine, thin stools, pale face, sweating in the cold and other symptoms. Each person’s symptoms are different and should be treated in conjunction with other medical conditions. If cold sweating is caused by Yang deficiency, it can be treated with medicines such as Zuo Gui Pill, Pian Zi Lizhong Tang, and Bao Yuan Tang under the guidance of a doctor. Cold sweating can also be caused by other diseases, such as colds, hypoglycemia, hypovolemic shock and other diseases. It is necessary to find the cause of the disease under the guidance of a doctor before treatment.
