Question
How should oral temperature be measured? What is the normal range for oral temperature, and what is the oral temperature during fever?
Answer
The method for measuring oral temperature typically involves placing a thermometer under the tongue and leaving it in place for about 3 minutes. The normal oral temperature for adults is generally between 36.3 to 37.3 degrees Celsius, but this range can vary from person to person and is influenced by factors such as physical activity, eating, and environmental temperature. During fever, the oral temperature may exceed this normal range. Low fever usually falls between 37.3 to 38 degrees Celsius, moderate fever is between 38.1 to 39 degrees Celsius, and high fever is between 39.1 to 41 degrees Celsius. Temperatures above 41 degrees Celsius are considered hyperpyrexia. However, these values are for reference only, and actual conditions may vary due to individual differences.
