PROBLEM TO BE SOLVED: To provide a technology for appropriately executing thermoregulation by obtaining a thermoregulation index on the basis of the state of a living body and executing the thermoregulation corresponding to the thermoregulation index.SOLUTION: A state detection part detects the state of a living body a thermoregulation operation part regulates the body temperature of the living body by executing the operation of at least one of heating and cooling to the living body on the basis of the state of the living body detected in the state detection part and a control part obtains a thermoregulation index on the basis of the detection value of the state of the living body by the state detection part, and operates the thermoregulation operation part on the basis of the thermoregulation index.
