"How long should an underarm thermometer be kept in place?"

Using an Axillary Thermometer for Body Temperature Measurement

Measuring body temperature with an axillary (underarm) thermometer is a common and convenient method. The standard measurement time typically ranges from 5 to 10 minutes, though specific durations may vary due to environmental factors, thermometer type, individual differences, and usage methods. If the temperature measurement results are inaccurate or questionable, it is advisable to promptly consult a doctor or a healthcare professional. Details are as follows:

1. Basic Measurement Time

In general, the standard measurement time for an axillary thermometer is 5 to 10 minutes. This ensures that the thermometer can fully detect the underarm temperature for an accurate reading. For traditional mercury thermometers, it is often recommended to hold them for 10 minutes to obtain a more precise result. In contrast, modern electronic thermometers usually require only 5 minutes or less to complete the measurement.

2. Environmental Factors

The temperature and humidity of the external environment can affect the measurement time and accuracy of an axillary thermometer. In cold or humid conditions, the thermometer may take longer to stabilize and read the body temperature accurately. When taking a temperature, strive to do so under room temperature conditions and avoid using the thermometer in extreme temperature environments to ensure the accuracy of the measurement results.

3. Thermometer Type

Different types of thermometers vary in measurement time. Traditional mercury thermometers generally require around 10 minutes, while electronic thermometers, with their more sensitive sensors, often only need 5 minutes or less. When using an electronic thermometer, ensure you follow the instructions in the manual to guarantee the accuracy of the reading.

4. Individual Differences

There are variations in the speed of temperature conduction in different individuals' underarms, which may affect the measurement time of the thermometer. Some people have faster temperature conduction in their underarms, allowing the thermometer to read a stable temperature in a shorter time, while others may require a longer period. When using an axillary thermometer, adjusting the measurement time according to individual conditions is necessary.

5. Usage Method

Correct usage is crucial for the accuracy and timing of body temperature measurements. Place the thermometer in the center of the underarm and ensure it is pressed firmly against the skin. During the measurement, keep the upper arm naturally hanging to ensure full contact between the thermometer and the underarm. Avoid moving the thermometer during the measurement process to prevent affecting the accuracy of the reading. Read the instructions before use to ensure correct operation.

When measuring body temperature with an axillary thermometer, the standard measurement time is typically 5 to 10 minutes, but specific durations may be influenced by various factors. To obtain an accurate temperature reading, it is recommended to follow the guidance of a doctor or the manual and consult a professional if in doubt.
