Generally children have a basal body temperature of 38 degrees Celsius or less as a low fever and over 39 degrees Celsius as a high fever. If a baby has a fever of 38.5 degrees, it is considered to be a moderate fever. There are many conditions that cause fever, specifically caused by both physiological and pathological. First, we can observe whether the child is sleeping peacefully. If the child is sleeping very peacefully, the fever is considered to be physiologically caused and only physical cooling is needed at this time. To see if the ambient temperature is too high, or if the child is wearing too thick clothing, reduce the child’s clothing appropriately, pay attention to the ventilation of the room, and also wipe the child’s forehead or palm with a towel. These can be effective for physical cooling. If the child’s sleeping appearance is very painful, accompanied by sweating and frowning symptoms, it is considered pathological. In this case, you should take your child to a regular children’s hospital for a checkup, preferably with a blood test. Then treat the symptoms according to the condition. There are many causes of fever in babies, parents must be extra careful when taking their children, according to the weather appropriate to add or remove clothing, do not let the child too cold or too hot.
