fever means enhance of body temperature?

fever means enhance of body temperature?

Enhance of body temperature 3 types Physiological Body T↑ Hyperthermia Pathological 40℃ Fever 36℃

Physiological ~ Pathological ~ Body T↑ Enhance of body temperature 3 types 36 ℃ 40 ℃

Hyperthermia due to a disturbance of thermal regulator control excessive heat production decreased dissipation loss of regulation 界常

Fever definition a regulatory body temperature elevation response to the pyrogen, it is induced by an upward shift of the set-point in thermoregulatory center
