Data obtained from Nebraska's workers' compensation agency on compensation claims related to the adverse effects of environmental heat, such as heat stroke, sunstroke, heat cramps and heat exhaustion, but not sunburn, were plotted against air temperature data available for each weather station in Nebraska for 104 days of data. The regression model used demonstrated the existence of a direct correlation between the climatic heat level prevailing in the State of Nebraska and the daily incidence of workers' compensation claims submitted for heat related disorders. As a result of the use of a single variable (air temperature), however, the model could not predict accurately the incidence of such disorders on a given day. Compensation claims for heat related disorders were infrequent in days when air temperature was below 27.8 degrees-C, while a sharp increase in the number of heat related claims was recorded in days when the daily temperatures exceeded this level. The author suggests that more accurate predictive models could be developed by including other weather parameters such as humidity and weather conditions on preceding days. Recommendations were made regarding the application of new predictive models and extension of workers' compensation data for the surveillance of heat disorders.
