Causes of night sweating in the second half of the night (abnormal sweating after going to sleep and stopping sweating after waking up) may be due to insufficiency of blood in the heart (insufficient blood in the heart), deficiency of yin and fire (deficiency of yin and essence in the body, resulting in hyperactivity of deficiency and fire), and deficiency of qi and yin (deficiency of both qi and yin fluids). If the body’s yin fluid is insufficient, it cannot restrain yang heat, which results in manifestations such as body thinning and five heart-heat. 1. Insufficiency of heart blood: Insufficiency of heart blood leads to the weakening of the role of moistening the heart and the official orifices of the body and the role of generating the heart and the spirit, and the patient often has palpitations (accelerated heartbeat, often accompanied by panic), night sweating, and lack of splendor of the face. It can be relieved by the application of Gui Spleen Pill and Ginseng Astragalus Wu Wei Zi Tablet. 2. Yin deficiency and fire exuberance: the body’s yin fluid cannot meet the basic needs of the organism, and the ability to restrain yang heat decreases, so that the yang heat that maintains the body’s normal life activities manifests itself in a morbid state, and the patient is often accompanied by emaciation, and the five hearts are burning with fever (the heart of the two hands and the heart of the two feet are hot, and consciously feel that their hearts are burning with fever) and other manifestations. The application of Zhi Bai Di Huang Wan and Kamehameha Nourishing Yin Granules can alleviate the symptoms. 3. Deficiency of both qi and yin: deficiency of both qi and yin is mostly caused by dietary irregularities and certain diseases that deplete both yin and yang, and is often characterized by emaciation and excessive sweating. It can be applied to stopping the deficiency sweating granules. No matter what kind of situation caused by night sweating, it is recommended to go to the hospital after formal examination, diagnosis of the condition of the symptomatic treatment, do not self-medication.
