ABSTRACT
Human thermal models serve several useful purposes. Perhaps the most important purpose is to incorporate diverse physiological and physical phenomena into an internally consistent representation of human thermal regulation. e diculty of accomplishing that goal was described by Stolwijk and Hardy in 1966 [4]. ey wrote in describing their model,

An important example of interaction between systems is provided by the eect of exercise on skin blood ow, which is discussed in some detail later.
