What is night sweats

Night sweating is the case of night sweating, to know why night sweating need to prophet to what is sweat, sweat when the formation of how. Modern medicine believes that sweat is a way of body temperature regulation and heat dissipation, usually due to the external climate, or increased heat production in the body caused by thermal stimulation resulting in the secretion of a fluid by the sweat glands. In Chinese medicine, sweat is a kind of body fluid, which is the fluid that is excreted on the surface of the body through the sweat pores on the surface of the skin by the evaporation of the body's yang energy. As the Yellow Emperor's Classic of Internal Medicine says: "Yang plus Yin is called sweat." Normal sweating has the effect of harmonizing yin and yang, regulating temperature, and moisturizing the skin.

Causes of night sweating

Chinese medicine believes that night sweating is a symptom of abnormal sweat discharge due to the imbalance of yin and yang in the body and the lack of solidity of the couples. Zhang Jinyue, a Ming Dynasty physician, in his book "Jinyue Quanshu - Sweating Evidence", made a systematic collation of night sweats. It is believed that night sweats are generally due to Yin deficiency. So why does Yin deficiency cause sweating at night? It turns out that Chinese medicine believes that sleep is closely related to the circulation of the body's Wei Qi and the strength and weakness of Yin and Yang, because Qi travels in the Yang meridian during the day and wakes up when Yang Qi is strong; at night it travels in the Yin meridian and sleeps when Yin Qi is strong. When the body Yin deficiency Yang hyperactivity, easily lead to internal heat, sleep from the body surface of the body Wei Qi convergence into the body, resulting in the body of internal heat aggravated, internal heat evaporation fluid leakage and sweating; after waking up the body Wei Qi from within the table, internal heat to reduce the skin surface can be solid, so the sweat stopped.
