The standard method for measuring human environmental heat stress is the WBGT. The WBGT apparatus is cumbersome and difficult to relate to standard psychrometric parameters or to other environmental measures such as the Botsball. The work presented in this paper was derived from thermodynamic and heat transfer considerations with corrections applied to be consistent with published experimental results.
