If it's pathological. Seeing this, I dare not look at America. Fan Tiebing's answer from Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine won my heart.

Su Wen's Theory of Yin and Yang says: "Yang is added to Yin, which means sweat." Sweating is a common clinical symptom, which reflects the rise and fall of yin and yang and the nature of pathogenic factors. In Treatise on Febrile Diseases, there is a very detailed discussion on the method of distinguishing sweat, especially on "sweating on the head". In the author's opinion, there are four mechanisms that lead to sweating on the head in Treatise on Febrile Diseases, namely, the combination of heat and tangible evil, the change of syndrome caused by misuse of purgative method, the fire robbing the body fluid to force it to be discharged, and the stagnation of yang and yang.
Heat is associated with tangible evil.
Heat is accumulated in the water phase and accumulated in the chest and hypochondrium, forming the syndrome of excess heat accumulating in the chest.
Due to stagnation of yang heat, water and drink in the body, chest obstruction, water and heat intertwined, heat can not penetrate outward, but transpiration upward, so the head sweats, and the body does not sweat. Symptoms are shown in 136: "typhoid fever has accumulated in the stomach for more than ten days, and there must be Dachaihu decoction for those who return to cold and heat; However, if the chest is knotted, there will be no heat. This is because water is also on the chest, but the head is sweating, mainly chest soup. " The treatment method is to clear away heat and promote diuresis, in parallel with Shenxiong Decoction, in order to eliminate pathogenic factors and restore healthy qi.
The combination of heat with blood and blood chamber forms the syndrome of heat entering blood chamber.
The main symptoms of "bleeding" are due to excess heat of Yangming, invading the blood chamber, and pathogenic heat forcing blood to rush. Pathogenic heat takes advantage of the emptiness of blood chamber and bloody fight, which leads to the obstruction of circulation of qi, so blood heat can not be fumigated in the body. Therefore, it is called "sweating on the head". See article 2 16: "Yangming disease, when blood is rushing, this is heat entering the blood chamber. When sweating on the head, it pricks at the door of the period, and the more sweating it becomes." Acupuncture at the door during the period can benefit liver qi, purge liver fire, promote qi circulation, harmonize blood vessels, sweat out pathogens and recover from illness.
Damp-heat combined with fumigation of liver and gallbladder produces damp-heat yellowing syndrome.
Heat is the evil of yang, which will sweat from the exterior, but it will accumulate because of dampness and depression, and the triple energizer will get out of control, so it will be fumigated by damp heat, so it will sweat from the head. See article 236 for symptoms: "Yangming disease, fever and sweating, which is excess heat and cannot be yellow." However, if the head sweats, the body does not sweat, the neck retracts, and urination is unfavorable, people will suffer from sharbat's pulp. This is because blood stasis will turn yellow at home. Yinchenhao decoction is the main method. "
Misuse of purgative therapy leads to syndrome changes.
Misuse of purgation can lead to chest obstruction or damp-heat yellowing.
If the chest is mistaken, heat will combine with phlegm and water visible in the body; If the chest does not knot, the heat will be wet and stagnant, and it will not be discharged. Both can cause sweating. See 134 for symptoms: "Sun disease, pulse floating, floating as wind, moving as heat, moving as pain, moving as deficiency, headache and fever, slight night sweats, aversion to cold." On the contrary, the movement is delayed and the pain is rejected in the diaphragm. Emptiness in the stomach, polite diaphragmatic movement, shortness of breath, irritability, chagrin in the heart, depressed yang and hard heart are the main causes of chest obstruction and chest tightness. If you don't have a chest knot, but your head sweats, the rest won't sweat, and you will return to your neck. It is not good to urinate, and the body will turn yellow. "
Misuse of lower methods will lead to hydrothermal interconnection.
The evil heat and water in the body are stagnant, but if you can't reach the outside and rush up, you will see "sweating on your head." See the article 147 for the symptoms: "On the 5th or 6th day of typhoid fever, sweating has resumed, the chest and hypochondrium are full of slight knots, urination is unfavorable, and people are thirsty and do not vomit, but their heads are sweating, and cold and heat are one after another, which makes people upset and still remains unsolved. The treatment is mainly Chaihu Guizhi Ganjiang Decoction. " Give Chaihu Guizhi Ganjiang decoction to harmonize cardinal, drink warm boiled water, the qi can pass, the exterior and interior can be reconciled, the whole body sweats, the evil is removed and the disease is removed, and the yang is recovered smoothly.
If the law is not done properly, the yang floats on the top.
When the internal qi is not full, the bitter and cold diarrhea is misused, hurting the innocent, exhausting the yin in the lower part and taking off the yang in the upper part, so it is seen that "sweat comes from the forehead". See article 2 19 for symptoms: "Sanyang syndrome, abdominal weight, difficulty in rolling over, foul mouth and dirty face, delirium and enuresis. Sweating makes you talk nonsense. Sweat on his forehead, cold hands and feet. Self-sweating, white tiger soup is the main one. "
Misuse of purgative therapy leads to heat depression in chest and diaphragm
Misuse of purgation will inevitably damage the stomach qi, leading to emptiness in the stomach, evil spirits taking advantage of it, invisible heat merging between the chest and diaphragm, and stagnation of heat steaming up, so "only the head sweats." See Article 228 for the symptoms: "Yangming disease, fever outside, warm hands and feet, no knot in the chest, regret in the heart?" You don't have to eat when you are hungry, and soup is the main thing when you sweat. "With gardenia black bean soup, clear stagnation heat chest diaphragm, eliminate the syndrome.
Fire injures body fluid, and heat forces body fluid.
Yang heat forcing steaming, body fluid leakage, should make the whole body sweat. However, the fire robbery makes the body fluid deficient, so the yin does not converge the yang, and the yang heat attacks the body, resulting in "sweating on the head." There are 200 kinds of symptoms: "Yangming disease, excessive internal heat, slight perspiration on the forehead, and people who have difficulty urinating will turn yellow." Article 1 1 1: "Sun-induced stroke, sweating due to fire, pathogenic wind being heated, qi and blood overflowing, losing its normal state. The two yang phases are smoldering and the body is yellow. Yang is strong, and it is difficult to urinate due to yin deficiency. Exhausted yin and yang, stuffy body and sweating, full neck, full abdomen and wheezing, dry mouth and sore throat, or no stool. If it is long, it will be awkward, hands and feet will be disturbed, and clothes will touch the bed. It can be cured if it is convenient. "
Shao yang yang Wei Jie
Shaoyang governs the release of qi, and triple energizer is the channel of qi of the whole body. At present, the shaoyang cardinal is unfavorable, and the yang is depressed inside, so it can't be declared, but it is steamed on the upper body, so "only the head sweats." The symptoms are shown in 148: "On the fifth and sixth day of typhoid fever, head sweating, slight aversion to cold, cold hands and feet, fullness in the heart, scanty food, hard stools, and thready pulse. This is a light knot of yang, and there must be exterior-interior syndrome." It is necessary to use Xiaochaihu decoction to harmonize the cardinal, publicize the exterior and interior, so that the upper energizer can penetrate, the body fluid can descend, the stomach qi can be relaxed due to harmony, the whole body sweats, and all the symptoms in the exterior and interior can be eliminated.
Through the analysis of the above provisions, it can be seen that "only sweating on the head" only appears in Sanyang meridian diseases, not Yin San meridian diseases, and the main pathogenesis of "only sweating on the head" is as Ye said: "The head is the meeting of all yang, evil will fight all yang, and body fluid will gather in one place, so sweat comes from the head." At the same time, it is necessary to pay attention to the difference from the normal situation of "sweating on the head", such as the name of steamer head disease, which means that children sweat on their heads while sleeping without other symptoms; Normal healthy people will also see head sweating when eating spicy food or hot food, which is a physiological phenomenon. Careful observation in clinic is of great benefit to improve clinical efficacy.
