The causes of night sweating in children (abnormal sweating after going to sleep and stopping after waking up) may be related to yin deficiency and internal heat, imbalance of Ying and Wei, and deficiency of lung, spleen and qi, etc. They can be treated through dietary therapy, medicines for regulating Ying and Wei (to make the body’s internal and external qi smooth and in their respective areas of operation), and qi and surface-strengthening medicines. 1. Yin deficiency and internal heat: Because of the deficiency of yin in children’s bodies, yin can’t control yang, and heat forces the fluid to go out, which may lead to the phenomenon of night sweating. It can be improved through dietary therapy by consuming foods that nourish yin and clear away heat (nourish yin essence and clear away heat), as well as promote the production of fluids and moisturize dryness, such as bird’s nests and silver ears. 2. Imbalance of Ying and Wei: Wei is strong and Ying is weak, Yang qi is oversteeped on the surface of the muscle, internal compression of Ying yin, and externalization of fluids will lead to the phenomenon of night sweating. It can be treated by taking medicines that harmonize Ying and Wei (making the body’s internal and external qi smooth, each in its own way), such as Astragalus and Gui Zhi Wu Wu Tang, Gui Zhi Granules, and so on. 3. Lung, spleen and qi deficiency: Children with a weak spleen and stomach and insufficient qi and blood sources lead to lung, spleen and qi deficiency. If the qi is deficient, it cannot consolidate the fluid and the sweat comes out of the surface, resulting in night sweating. You can take medicines to benefit qi and consolidate the surface, such as Yubingfeng Granules or Deficiency Sweat Stop Granules, which can benefit qi and consolidate the surface to stop sweating (stop sweating by consolidating the surface of the muscle). It is recommended that the patient go to the hospital in time to see a doctor, after clarifying the cause of the disease, standardized treatment, specific drugs need to be used under the guidance of the doctor.
