Will a baby\’s fever really damage his brain? See what senior doctors say

As soon as a child has a fever, parents become frightened, fearing that the child\’s fever will burn out his brain and make him crazy. There are also many people who don\’t take fever seriously, thinking that the fever will go away automatically if they rest. Everyone is still too young. 1. How to calculate a fever? Like this… My mother: The fever reached 39 degrees 5, and she actually laughed for 3 minutes. She couldn\’t calm down anymore. Is she crazy because of the fever? ▌1. This is considered a fever. 37.4~37.9℃ is a low fever. 38~38.9℃ is a moderate fever. 39~41℃ is a high fever. 41℃ or above is an ultra-high fever. PS: The reference value of normal human body temperature is as follows. Oral temperature is: 36.3℃~37.2℃. . The axillary temperature is 0.3℃~0.6℃ lower than the oral temperature, and the rectal temperature is 0.3℃~0.5℃ higher than the oral temperature. ▌2. Fever is a symptom, not a cause. Fever is an instinctive response of the human body to fight against disease. It is a \”symptom\” of fighting infection rather than a \”disease\”. Generally, a fever will only make the body uncomfortable. The most important thing is to find and treat the cause of the fever. Some diseases can cause brain damage. Fever is mostly caused by bacteria or viruses, such as colds, gastroenteritis, ear infections, bronchiolitis, etc., which will be described in detail below. 2. Can fever really burn out the brain? ▌1. Fever itself will not cause damage to the brain. In fact, it is a misunderstanding that high fever will burn out the brain. Under normal circumstances, a simple fever will not cause direct damage to the body\’s organs. No, look at that kid whose brain is burned out and loses consciousness after he or she has a fever. When the human body has a fever, the highest temperature rarely exceeds 41°C. If it exceeds this temperature, it is very likely that the child is suffering from encephalitis. Meningitis, polio or other diseases. Moreover, encephalitis or meningitis is not caused by a high fever but by an infection with a virus that attacks the brain and has nothing to do with fever. It is usually accompanied by symptoms such as unconsciousness, drowsiness, gibbering, and severe headache. PS: Current medical research believes that the body temperature must reach 41~42℃ or even higher for more than 30 minutes before it will destroy the protein structure of brain cells and cause brain cell damage or death. Clinically, this is only true in a few special situations, such as heat stroke, Malignant hyperthermia, congenital lack of sweat glands, etc. ▌2. Why do children have more frequent fevers than adults? Fever is a normal response of the body to fight against diseases. Children’s immune system is not perfect, and bacteria and viruses that they have not been exposed to can easily cause infection and fever. As the child gets older, the frequency of fever will become less and less. Fever is a normal response of the human body to fight against diseases. The fever will stop when it reaches a certain level, and the fever will not continue indefinitely. The reason why the fever persists is because the germs have not been eliminated, and the fever will naturally subside after the immune system kills the germs. If the fever persists, don\’t just focus on physical cooling. You must go to the hospital to see a doctor as soon as possible. 3. Common causes of fever and care methods ▌ 1. Common causes of fever ① Infection caused by pathogens such as bacteria or viruses. Upper respiratory tract infection: common symptoms such as runny nose, sore throat, etc. Gastrointestinal infections: Stomach colds such as bacterial gastroenteritis or viruses usually include nausea, vomiting, or diarrhea. Symptoms of urinary tract infection include frequent urination, painful urination, hematuria, etc. Just like a childIf it cannot be expressed, a urine test may be needed to confirm and antibiotic treatment is required. ② Rheumatic immune diseases such as lupus erythematosus, vasculitis, rheumatoid arthritis, etc. can also cause fever. ③ Unexplained fever may have something bad in your body, such as malignant tumors. ▌2. Have a fever? This treatment is most appropriate. When the body temperature reaches above 38.5℃, the fever should be reduced under the guidance of a doctor. People whose body temperature is below 38.5℃ can choose simple physical cooling first. Methods for physical cooling at home: ① Drink more water. First, drink more water to avoid dehydration caused by excessive sweating during fever. ②Heat dissipation and sweat elimination. Wear comfortable and sweat-absorbent clothing to help dissipate heat. Don\’t cover yourself with a quilt and wear too many clothes to induce sweating. Sweating too much can easily lead to dehydration of the body. ③ Warm water bath and warm bath can help relieve fever symptoms. In addition, people with metabolic diseases and chronic cardiopulmonary diseases should not use ice pillows to reduce fever when they have a fever. Because they cannot cope with the sudden increase in energy demand, it may lead to the collapse of the metabolic mechanism or cardiopulmonary failure. Also, it is not recommended to use alcohol to cool down. If the following situations occur, do not wait and seek medical attention immediately: Children: ① Infants under 3 months old ② Refusal to eat or drink ③ Severe fatigue or confusion ④ Severe vomiting (jet type) ⑤ Persistent fever PS: Children under 6 months old are experiencing fever Because the condition changes rapidly, timely treatment is required. Adults: ① Severe headache or photophobia ② Difficulty breathing, chest pain, sore throat, abdominal pain, difficulty urinating ③ Abnormal tiredness, irritability, convulsions/convulsions, confusion or disorder If you have a fever, will taking antipyretics help? The role of antipyretics is usually to lower the body temperature for 4 to 6 hours to provide relief, but they cannot cure a fever or cold. Generally, a cold and fever will last for two to three days. During this period, antipyretics can be used to cool down the fever. The medication can be stopped when the fever is completely subsided. However, it is not recommended to buy medicine and take it yourself. It is best to find out the cause of the disease first.
