Rising temperatures around the globe pose a threat to human life in many hot locations. Previous work on this subject by Sherwood and Huber uses very rudimentary approximations to determine what conditions are life-threatening. Many environmental interactions, such as sunlight and thermal radiation, were ignored. This work attempts to develop a more complete model of human heat regulation based on physical principles for the purpose of evaluating the severity of heat stresses under given environmental conditions. A computer model is developed and compared with the results from previous work, and differences are noted. In particular, the wet-bulb temperature required to reach lethal body temperatures is found to be lower than previously implied.
