The majority of people who sweat less are weak and cold, because the body’s basal metabolic rate is at a low level for a long time, the body’s utilization of various nutrients is not high, muscle activity is much lower than normal, from the physiological point of view, resulting in less evaporation of human tissue fluid, prone to sweating symptoms. Less sweating is because there is not enough heat in the body to evaporate fluids, which is a deficient cold physique. Clinically, it is necessary to adjust one’s lifestyle and perform appropriate exercises to improve the physique. If the symptoms of low temperature in the hands, feet and extremities are present, you need to take appropriate Chinese medicine for regulation, such as Si Wei Tang. In addition to the symptoms of less sweating, people with a deficient cold constitution may also have symptoms of poor spleen and stomach function, such as frequent bloating and diarrhea, which can also be regulated by taking Si Jun Zi Tang.
