Sep 1, 2016 · Body temperature measurement and definitions. Normal body temperature is between 36.0 and 37.5 °C, with intraindividual variability of 0.5–1.0 °C depending on the time of day (low in early morning, peak in early afternoon/late evening) [ 1, 20 ]. Elevated body temperature is classified as pyrexia or hyperthermia.
