Core body temperature is a key indicator of an individual’s physiological state.
The human core body temperature is theoretically maintained around a target value of 37°C, within a range of approximately 1°C, ensuring the proper functioning of the body. However, temperature regulation varies between individuals, as its dynamics can change depending on age, sex, season and other factors. Additionally, it can fluctuate due to exposure to extreme environmental conditions or the onset of a pathology, infection, or other health conditions.
This makes core body temperature a fundamental biomarker in many research protocols, as well as in patient monitoring and management, from routine situations to the most critical cases.
While various temperature monitoring tools exist, very few, if any, allow for reliable, precise, and continuous core body temperature monitoring.
