First of all, drink more water. When the child has a fever, more water loss, need to replenish enough water, at this time to drink cold water can meet the needs, and do not need to drink ice water, because the gastrointestinal tract itself when the fever has reduced digestive function, ice water on the gastrointestinal mucosa damage again, affecting the recovery of digestive function. Secondly, enter the liquid food. When fever is reduced digestive function, at this time to eat easily digestible food, such as thin rice, porridge, rotten noodles, etc., high-fat food is easy to increase the gastrointestinal burden, affecting the recovery of the disease, should be avoided. Once again, you can eat more fruits and vegetables. These foods are good for keeping the intestinal tract open, maintaining normal gastrointestinal function, and rich in vitamins, of which vitamin C has an antiviral effect, which is conducive to disease improvement. Finally, it is necessary to eat in moderation. Be sure to look at the child’s appetite status. If the child has a poor appetite, do not force the child to eat, because the digestive function is reduced, that’s why he or she shows a poor appetite. If you force the child to eat, not only will it not be digested and absorbed, but it will add to the gastrointestinal burden. A child was hospitalized with a fever and asked the parents how high the temperature was, and they said 38 degrees and had taken antipyretic medication. I told the parents not to take antipyretic medication below 39 degrees if the child did not have a high fever and was in shock. Fever in children is usually high, often exceeding 39 degrees Celsius, and parents are very nervous. Understanding the characteristics of fever and the key points of care can help your child’s condition control and recovery. Fever is most often seen in respiratory infections, most commonly colds, and usually lasts 3-5 days, so within these days, in addition to the medications prescribed by the doctor, parental care is more important: encourage your child to drink more water, take more temperature, and use physical cooling when the temperature starts to rise, so that the temperature can be controlled as much as possible below 39 degrees, thus facilitating the child’s own ability to fight the disease. The rash can be seen in different diseases and has its own characteristics: one day rash in fever is seen in rubella; two days rash in fever is seen in measles; three days rash in fever is seen in toddler rash; five days rash in fever is seen in typhus; seven days rash in fever is seen in typhoid fever, but of course, the rash will depend on the doctor’s identification and diagnosis to be accurate. In short, children with fever should not blindly reduce fever, fever of 39 degrees or less is harmless.
