This paper details four discrete zones which describe the limit of human physiological and performance capabilities in conditions of elevated environmental temperature. Boundaries to these zones are expressed in both environmental and physiological parameters. The practical application of these zones may be realized where individuals are exposed to continuous or intermittent heat stress.
