In the hot summer, the heat is unbearable, and our emergency room is also very busy, and there are many patients with “cold and fever”, mostly young people. The main manifestations: fever, headache or head heavy, general weakness, no sweating, poor appetite, with abdominal pain, diarrhea. Causes: blowing fans, air conditioning, cold showers, eating a lot of cold drinks. Analysis of the condition: the weather is too hot, poor sleep, the body’s own regulation to resist external stimuli or adapt to changes in the external environment, the ability to enjoy fans, air conditioning, cold showers, cold drinks in the case of high heat, resulting in extreme imbalance between the internal and external environment of the body, the temperature difference is too large, the body’s thermoregulatory center disorder imbalance: peripheral vascular occlusion, the beginning of skin sensitivity, fear of cold, scalp pain, cold limbs, while the central heat production increased In the beginning, the skin is sensitive, cold, scalp pain, cold limbs, while the central heat production increases, so that the internal heat is not allowed to be distributed, the body temperature rises, but there is no sweating, and the body temperature is difficult to fall. Due to the high temperature and slow blood circulation in the body, it leads to dizziness and pain, general weakness, gastrointestinal malfunction, poor nausea and even abdominal pain and diarrhea. Chinese medicine identification: external wind and cold, internal heat and humidity. Differentiation: The manifestation of this “cold” is very similar to “heat stroke”, but there are differences in the etiology: the former is heat-induced wind-cold, the so-called “cold”; the latter is caused by simple overheating, often The latter is caused by simple overheating, often due to prolonged high-temperature environments such as prolonged sun exposure, high temperature + humid environments, etc., resulting in profuse sweating and loss of body water, resulting in the body’s temperature regulation unable to counteract the overheating of the external environment, without peripheral vasoconstriction in the early stage. Clinical manifestations of heat stroke tend to be higher in temperature. Prevention: The prevention of “cold” or “heatstroke” is actually relatively simple for the cause of the disease. First, avoid prolonged high heat environment; second, do not immediately enter the cool environment from high heat state with excessive temperature difference, do not blow the fan, air conditioning, do not take a cold shower immediately after overheating, drink too cold drinks. You can drink a drink with salt to prevent excessive sweating, you can also drink green bean soup to prevent heatstroke (green beans boiled for 10-15 minutes first to take the upper clear to cool and then drink, the upper clear appears green, the best effect of heat detoxification). Mung bean water + ginger slices can sweat and clear internal heat to prevent and control heat + wind chill cold. There is also oral patchouli water, capsules and other drugs. Treatment: If the onset has been inadvertent, finally go to the hospital for treatment, cooling, replenishing water electrolytes, etc.
