WHAT IS BODY TEMPERATURE? Body temperature refers to the internal tempe- rature of the body (core temperature). ‘Normal’ body temperature fl uctuates over the course of 24 hours. It tends to be lowest in the early morning and highest in the late afternoon. Body temperature also varies depending on the part of the body where the temperature is measured and also differs with age.
