The child’s body temperature of 37.2℃ is a normal body temperature, and any body temperature lower than 37.4℃ is a normal body temperature. However, if the child’s temperature at this time is higher than the temperature in daily life, we should observe whether the child has sneezing, runny nose, loss of appetite, nausea, diarrhea, abdominal distension, whether there is frequent urination, urinary urgency, difficulty in urination and other manifestations, and we should take a comprehensive look at whether the child’s mental state is very good. If there are corresponding manifestations, the child may be a symptom of early stage of the disease, with a body temperature slightly higher than the temperature in daily life, and the child needs to be closely observed and further adjusted and treated according to the symptoms that appear. If the child’s body temperature is 37.2℃ without any abnormal performance, it is also possible that the child is wearing too much clothing, drinking too little water, or the temperature is slightly higher than the daily life due to the excessive heat in summer, so parents should not worry.
