When taking a temperature with a thermometer, you need to shake the reading on the thermometer to below 35 degrees before taking the measurement. Under normal circumstances the axillary body temperature is between 36-37°C. Sometimes the body temperature can be low, possibly below 36°C, but rarely below 35°C. After dumping the thermometer to this temperature, it will not affect the normal measurement of body temperature, to be able to measure the temperature above 35 ℃, in the measurement, the axillary temperature should be measured for at least 5 minutes, preferably up to 10 minutes, also need to avoid too cold or too hot objects, such as around an ice pack, or a warm water bag, will affect the normal measurement. If the oral and anal temperature is measured, it needs to be measured for about 5 minutes, and then when the oral temperature is measured, also try not to eat too cold or too hot food.
