A prolonged temperature of 37.2 to 37.3 degrees Celsius in babies may be normal. A baby’s normal axillary temperature is 36.3 to 37.2 degrees Celsius, but body temperature is affected by individual constitution, age, gender and environment. As the thermoregulatory center of a baby is not fully developed, the baby’s thermoregulatory function is incomplete, so the baby’s body temperature is easily affected by the environment and age. As babies are at their peak of growth and development, their metabolism is vigorous, and their breathing and heart rate are fast, so there is no need to worry if the baby’s temperature remains at 37.2 to 37.3 degrees for a long period of time, and if the baby’s appetite is normal and his or her spirit is good. However, if the baby’s temperature continues to rise 37.5 degrees and above, and there is a loss of appetite, poor spirits, etc., you need to go to the hospital in time for treatment.
