Many people think that if a fever is not cooled down in time, people will be “burned silly” or their eyes will be “burned blind” or their ears will be “burned deaf”, but in fact, these are unlikely to happen. Fever is a favorable defense reaction of the human body, can kill the invading pathogenic microorganisms, in less than 38.5 degrees Celsius, will not have a major impact on the human body. If the temperature is rushed down at this time, it will instead weaken the body’s defenses. However, when the body temperature is higher than 38.5 degrees Celsius, the normal physiological functions of the human body will be affected, causing various discomforts, serious cases may even coma, liver and kidney function damage, children may also appear high fever convulsions, etc., this time it is necessary to use antipyretic drugs under the guidance of a doctor. Fever-reducing drugs can only be used for 3 days When the body temperature is higher than 38.5 degrees Celsius, you can start taking fever-reducing drugs. However, in the conventional sense, antipyretics only cool down the temperature, but do not “destroy” the pathogen causing the disease, which is really an “emergency treatment of its symptoms”. For example, when bacterial pneumonia causes high fever, the first need to use antibiotics to control bacteria, so as to achieve the effect of complete anti-inflammatory cooling, which is the “bottom of the barrel” of the cure. If you only use antipyretic drugs, the temperature can only temporarily come down, and then rise again, and repeated use of antipyretic drugs will also lead to the patient too much sweating and deficiency, but not conducive to treatment. When the body temperature drops below 38.5 degrees Celsius, you can stop using antipyretic drugs. Some antipyretic drugs have certain hepatic and renal toxicity and neurotoxicity, so you must pay attention to the dosage when using them. Generally speaking, do not use them for more than 3 days in a row. Before and after using antipyretic drugs, pay attention to monitoring the body temperature, and use them only when they are needed, as soon as they are ready. Compared to taking antipyretic drugs, it is easier and safer to lower the temperature physically. Such as using warm water baths (using a towel dipped in warm water in the neck, armpits, thigh root wipe), but also available ice packs, 40% alcohol baths to cool down.
