A baby with a high body temperature but no fever should refer to a temperature that is hot to the touch, but not to the extent of fever. A feverish temperature refers to a body temperature greater than or equal to 37.4°C and is clinically defined as a fever. When the baby’s daily body temperature is not very hot and the parents feel the high temperature, it may be caused by the rise in temperature caused by the parents putting too much clothing on the baby, or the temperature may rise because the parents give the baby less water to drink. It may also be due to hot weather, such as a hot summer day, so the baby’s temperature will be slightly higher. When you feel your baby’s temperature is high, you should clarify whether your child is showing signs of discomfort, whether he or she is eating poorly, whether he or she has sneezing or a runny nose, or whether he or she has bloating or diarrhea. Analyze whether it is caused by disease factors or under physiological conditions, such as clothing or environmental conditions, and analyze the specific problem.
