Sweating easily can be caused by either a Yin deficiency or a Yang deficiency. Both yin and yang deficiencies can cause sweating, but the sweating and accompanying symptoms are different. Yin deficiency sweating mostly refers to night sweats (abnormal sweating after going to sleep, but sweating stops after waking up); Yang deficiency sweating mostly refers to spontaneous sweating (involuntary sweating during the day, aggravated by the slightest movement of sweating).
Yin deficiency sweating refers to night sweating, i.e., sweating while sleeping, sweating stops after waking up, with symptoms such as hot flashes. Yin deficiency and hyperactivity of yang, internalized heat, when sleeping, weiyang (yang qi on the surface of the muscle) into the inside, vaporizing fluid and sweating, waking up weiyang out of the surface, so sweating stops.
Yang deficiency sweating refers to yang deficiency self-sweating, that is, often sweating, especially after the activity, with fatigue (mental exhaustion, physical weakness), less breath and lazy speech (lack of strength, do not want to talk), cold limbs cold and other symptoms. Yang deficiency, can not protect the surface of the muscle, fluid leakage and sweating, movement is the consumption of Yang, so sweating aggravated by activity.
Both yin and yang deficiencies may lead to sweating, but the treatments are not the same. A professional Chinese medicine doctor is needed to judge whether it is yin or yang deficiency according to the symptoms, and it is appropriate to adopt corresponding treatment measures, avoiding self-judgment and medication.
