The temperature that keeps a human body healthy and out of illness is 39 degree celcius.
Step-by-step explanation:
The main reason for this is that the chemical reactions going on inside the body of our and most other animals, which keeps us alive, keeps moving, are adjusted in 37-38 degrees. It operates well around Celsius.
Normal human body-temperature (normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F).[8]
Human body temperature varies. It depends on gender, age, time of day, exertion level, health status (such as illness and menstruation), what part of the body the measurement is taken at, state of consciousness (waking, sleeping, sedated), and emotions. Body temperature is kept in normal range by thermoregulation, in which adjustment of temperature is triggered by the central nervous system.
