Sweaty palms are a very common symptom in clinical practice, and most of its causes are not particularly clear, mainly manifesting as symmetrical and irregular sweating of the hands, which can occur even in winter or when the outside temperature is low. The secretion of human sweat glands is governed by sympathetic nerves, and sweaty palms are actually the result of unexplained sympathetic hyperexcitability. The sweaty palms can be caused by tension, stress or high outside temperature, which can cause abnormal hand sweating. The occurrence of this condition is related to the individual’s physical condition and endocrine factors. In general, most healthy people do not sweat or sweat very little on the palms of their hands, even if their whole body sweats due to high external temperature. The sweaty palms are not sweaty elsewhere in the body, but the palms are sweaty. Sweating in the palms of the hands is not necessarily a problem if it is very mild, but it is mostly seen in people with a weak constitution. This condition is considered to be caused by kidney yin deficiency in Chinese medicine, and there is no good way to treat this in most western medicine, while most patients have good results after Chinese medicine.
