Temperature readings vary from one healthy person to another and are influenced by factors such as age, gender, and ambient temperature. Temperature readings vary even in the same person at different times. Therefore, normal body temperatures can only be given as ranges.

Readings from different parts of the body also differ from each other. For example, rectal temperatures tend to be higher than oral (mouth) temperatures, and ear and armpit temperatures tend to be lower than oral temperatures. Here are ranges of average temperatures of healthy people taken from different body sites in various studies (Sund-Levander et al 2004):

Mouth            33.2°C to 38.2°C Armpit           35.5°C to 37.0°C Rectal           34.4°C...
