The summer is the hottest time of the year, a long time high temperature, resulting in excessive sweating, depletion of fluid, especially the old and weak people easily lead to disease. Chinese medicine believes that the blood and fluids from the same source, sweat for the heart of the liquid, especially over-sweating, resulting in the human body gas with liquid off, sweating death Yang, damage to the heart gas, fainting shock. Every summer season, we often hear the news of the community elderly children heat stroke, serious cases will also occur “heat stroke”. Summer is a very character of disease-causing evil 1, first of all, Chinese medicine believes that summer heat summer for the summer months of heat, the summer fire, with the nature of heat, fire is Yang, so the summer is the yang evil. The summer evil injury mostly shows a series of symptoms of Yang heat, such as high fever, heartburn, face red, irritability, pulse flooding, etc., known as injury to summer heat (or summer fever). 2, secondly, the summer has the nature of ascending and dispersing the summer evil is easy to offend the head and eyes, internal disturbance of the mind and spirit. It is also capable of injuring and depleting qi. Summer is Yang evil, Yang rise, so the summer evil invasion of the human body, can cause the coupling open and sweat. Sweat more injuries, fluid loss, there can be thirst and drink, dry lips and tongue, urinary redness and shortness. In a large number of sweating at the same time, often with the leakage of gas, and lead to gas deficiency, so injured in the summer, you can often see shortness of breath, or even suddenly fainted, unconsciousness of heat stroke. 3, summer is easy to hold wet evil summer season is not only hot climate, and often rainy and humid, hot steam and wet move, hot and humid permeate the space, the person’s and the whoosh, are not away from the hot and humid gas. For example, sleepy limbs, chest tightness, vomiting, loose stools and other symptoms of wet obstruction. Yin summer, Yang summer stupid not clear heatstroke has Yin summer, Yang summer points, Chinese medicine that “quiet and get the person for the Yin summer”, “moving and get the person for the Yang summer”. Due to long time in the hot sun, high temperature environment and work in the heatstroke that is “Yang heat”; summer due to too much cool caused by the heatstroke that is “Yin heat”. Jingyue quanquan” records: “Yin heat …… where people fear the summer cool, do not avoid the cold, or in the deep hall building, or in the shade of the wind and trees, or at first hot and cold time, not careful clothing. So that the cold evil attack on the surface of the muscle, and the disease for fever and headache, no sweat and cold, body shape constriction, limb aches and pains and other evidence.” “Whenever the heat and sun are in full bloom, or on long distances, or in the fields, and they do not spare any effort, so that the heat toxin injures the yin, and the disease is headache and irritability, great heat in the body, great thirst and sweat, floating pulse and asthma, or no gas to move and other certificates. This summer month heat, so the name of Yang summer.” How can we reduce the “summer”? In addition to preventing the occurrence of yin heat in addition to do not stay in the air-conditioned room for a long time, the indoor temperature should not be too low, do not crave cold drinks, should also pay attention to the following points: do not “fast cooling”: many friends from the outdoors to return or after exercise, in order to achieve the purpose of cooling in addition to the purpose of the sweat, like sweating immediately with a cold bath, so that the body “fast cooling”. Body “rapid cooling”. In fact, this is very harmful to the body, immediately after sweating with cold water bath will make the whole body pores close quickly, the heat can not be distributed and stagnant in the body, at this time, the heat will take the initiative to find the door. Therefore, after sweating it is best to first dry the body sweat, moderate rest and then rinse with warm water. Do not stay in the shade for too long: lawns, pavilions, shade, rivers and ponds, etc. are a good place to cool off, but these places are humid, should not stay too long. Because too greedy for cool is to lead to the occurrence of summer heat “culprit”, too humid environment is to lead to the occurrence of summer heat important “accomplices”, must not let the two in cahoots, or else, summer heat will be on your “favorite! The most important thing is that you should not let the two work together, otherwise the heatstroke will be your “favorite”. Therefore, if you feel cold or experience a drop in temperature, you should immediately add clothes or go back indoors. If you accidentally have a yin heat stroke, you can take wind-cold and cold medicine; if you have nausea and vomiting, you can take the Chinese medicine Huo Xiang Zheng Qi Shui (pills and capsules); if you have a fever and urinate less, you can take the Chinese medicine Liouyi San; and you should go to the hospital immediately if you have a serious condition. To prevent yang heatstroke, avoid prolonged exposure to the hot sun, especially for construction workers, police officers, sanitation workers, pedestrians, etc. Pay attention to the fact that the heat evil depletes qi and injures yin, causing symptoms such as dizziness, fatigue, thirst, headache, profuse sweating, reddening of the face, and elevated body temperature. Yang heat tends to develop very quickly. Due to the high dilatation of blood vessels on the surface of the body, too much blood is instilled into the body surface, and vital organs such as the brain and heart are deprived of blood, which can lead to shock, convulsions, coma and life-threatening conditions in severe cases. Therefore, once someone is found to have a headache, dizziness, flushing, body heat, sweating and other aura symptoms, it is important to save them as soon as possible. Specific methods include: quickly move the patient to a ventilated, cool place, fan, apply cool towels to cool down; sober people can drink green bean soup, light salt water, lotus leaf water, green tea, sour plum soup, etc., or eat watermelon; use cool oil to wipe the forehead, temples; take ten drops of water or RenDan, the old and weak patients can contain 2~3 tablets of American ginseng. Be careful not to use warm medicines, such as suhexiang pills. If the patient is unconscious, must call 120 for help. Press Baihui, pinch the human center can prompt the patient to wake up, in the front chest, back in the middle of the scraping effect is good.
