Patient's question:
No.Doctor's answer:
Normal body temperature is not a specific point but a range. The temperature in the deep parts of the body is relatively constant and uniform, referred to as deep body temperature. In contrast, the surface temperature is affected by various factors and exhibits significant fluctuations and differences, known as surface temperature. In clinical practice, the term "body temperature" refers to the average deep body temperature. It is generally represented by the temperatures in the mouth (sublingual), rectum, and armpit. Among these, rectal temperature is closest to deep body temperature.Normal values:
- Sublingual oral temperature: 37°C (range 36.2–37.2°C)
- Rectal temperature: 37.5°C (0.3–0.5°C higher than oral temperature)
