How long must you wait for an accurate temperature reading?

For obtaining an accurate temperature reading, waiting five minutes is essential as it allows the thermometer to stabilize and provide a reliable measurement. During this time, the thermometer can effectively reach an equilibrium with the body temperature being measured, especially if it is an oral reading, where factors like recent food or drink consumption can impact the results.

This five-minute standard helps ensure the accuracy of the reading, allowing the body temperature to be measured effectively without interference from external variables. It is important to be mindful of timing in order to avoid falsely elevated or decreased readings that could lead to inappropriate clinical decisions.
