A certain degree of sweating is good for your health, but if you sweat a lot, it is easy to cause dehydration, so it is recommended that patients take a shower and rehydrate in time. The bathroom is usually a relatively closed environment and the water temperature in the shower is relatively high, which will stimulate sympathetic excitation and thus cause sweat gland secretion. In addition, because of the high skin temperature in the shower, in order to increase heat dissipation, sweating is a normal physiological phenomenon. However, if the patient after bathing, there is a lot of sweating, waist and knee weakness, or even diarrhea, general fatigue and weakness of the symptoms, it is necessary to consider whether there are other diseases that cause the patient’s physical weakness. Different etiologies need to be analyzed according to the different conditions of the patients.
