ABSTRACT
That the internal temperature should be maintained at around 37°C dictates that there is a heat balance between the human body and its environment. That is, on average, heat transfer into the body and heat generation within the body must be balanced by heat outputs from the body. That is not to say that a steady state occurs, since a steady state involves unchanging temperatures, and temperatures within the body and avenues of heat exchange will vary; however, for a constant internal body temperature there will be a dynamic balance.
