Is a body temperature of 35°C in adults considered normal?

In medicine, a body temperature of 35°C in adults is not considered within the normal range and is usually classified as low body temperature or hypothermia. Generally, the normal body temperature of healthy adults varies slightly depending on the method of measurement. For example, axillary (underarm) temperature typically ranges from 36.0°C to 37.0°C, oral (mouth) temperature normally ranges from 36.3°C to 37.2°C, while rectal (anal) temperature tends to be slightly higher, ranging from 36.5°C to 37.7°C.

Physiological variations exist between individuals, and some people may naturally have a lower baseline body temperature while still maintaining normal physiological functions. However, if the body temperature remains consistently below 35°C, especially when accompanied by other symptoms such as shivering, fatigue, sluggishness, or slow heart rate, it should be considered an abnormal condition requiring timely medical attention. The physician will evaluate the cause of hypothermia based on medical history, physical examination, and necessary laboratory tests, and then formulate an appropriate treatment plan.
