What is the normal human body temperature range?

Normal human body temperature is usually around 36-37°C and can vary slightly depending on the method of measurement.
1. Axillary measurement method: the head end of the thermometer is placed in the patient’s armpit, and the patient is told to clamp the thermometer tightly, and the reading is taken after 10 minutes. The normal value is 36~37℃, and the armpits should be wiped before measurement to avoid dampness in the armpits affecting the result.
2. Mouth measurement: put the head end of the sterilized thermometer under the patient’s tongue, let him close his lips, 5 minutes after the reading. The normal value is 36.3~37.2℃.
3. Anal method: let the patient take the lateral position or prone position, the anal thermometer head end slowly inserted into the anus up to half the length of the thermometer, 5 minutes after the reading. The normal value is 36.5~37.7℃.
If you feel unwell, you should consult a doctor promptly.
