What causes prolonged sweating?

Long-term daytime sweating is a manifestation of qi deficiency. If it is long-term night sweating, it is called night sweat, which is a manifestation of yin deficiency. Long-term sweating may be a symptom in the evolution of a disease, such as endocarditis, hyperthyroidism, tuberculosis, rheumatic fever, diabetes, obesity and other diseases. These diseases should be ruled out first. Spontaneous sweating and night sweats are mostly caused by imbalance of yin and yang qi and blood, imbalance of emotion and heat fumigation, resulting in disharmony of Ying and Wei, disharmony of striae and abnormal leakage of sweat. Those who sweat from time to time and work more seriously are spontaneous sweating. Sweating occurs when sleeping, and sweating stops when waking up. These two symptoms can be manifested independently or simultaneously. At present, medicine also calls them vegetative nerve dysfunction.
