Introduction
The normal body temperature ranges from 36.1°C to 37.2°C. A temperature above 37.2°C is considered fever. Temperature can be measured orally, under the armpit, or on the forehead. Additionally, it can be measured in the ear canal using an infrared ear thermometer placed in the ear for 1 to 2 seconds. When reading the measurement, care should be taken to avoid interference from external temperatures.
The normal body temperature ranges from 36°C to 37.2°C. A temperature above 37.2°C is considered feverish. Body temperature can be measured orally, under the armpit, or on the forehead.
1. Oral Temperature Measurement
Place an electronic or mercury thermometer under the tongue for 3–5 minutes. Avoid breathing out or speaking while reading the result. Normal oral temperature ranges from 36.3 to 37.2°C.
2. Axillary (Armpit) Temperature Measurement
Place an electronic or mercury thermometer under the armpit for 5–10 minutes. Ensure that external temperatures do not affect the reading. Normal axillary temperature ranges from 36 to 37°C.
3. Forehead Temperature Measurement
Use an infrared thermometer and hold it on the forehead for 1–2 seconds. Ensure that external temperatures do not affect the reading. Normal forehead temperature ranges from 36 to 37°C, and readings above 37°C indicate fever.
In addition, temperature can also be measured in the ear canal using an infrared ear thermometer placed in the ear for 1–2 seconds. Avoid interference from external temperatures when taking the reading. When measuring body temperature, choose an appropriate thermometer and follow the manufacturer's instructions carefully.
