Self-sweating and night sweating are mostly caused by qi and yin deficiency, and patients can soak their feet, but the temperature should not be too high and the time too long. Self-sweating refers to not being affected by external factors, when sweating. Night sweating refers to sweating while sleeping and stopping after waking up. When the patient has symptoms of self-sweating and night sweating, it means that at this time the positive qi is weak, and both qi and yin are deficient (both qi and yin are deficient). It is also accompanied by chest tightness, fatigue, shortness of breath and loss of appetite. This type of patient, in daily life, is able to soak feet. However, it should be noted that the water temperature should not be too high and the time should not be too long, so as not to aggravate the leakage of sweat, leading to a more serious degree of qi and yin deficiency. Patients should also avoid spicy and stimulating food, if the symptoms persist, should go to the hospital, under the guidance of the physician to use the appropriate drugs for treatment.
