Heat stress

Heat exposure has been associated with unsafe work behaviors and elevated injury rates, through various mechanisms that likely include heat-related cognitive dysfunction. In preparation for a larger field study, a pilot study was completed among a small sample of underground miners to evaluate the study design for assessing physiologic and cognitive effects of heat strain. This talk will provide preliminary results of the pilot study and discuss future study plans, which include heat-related cognitive testing and physiologic data collection at multiple mines as well as within an environmental chamber. Data from both field and laboratory studies will be analyzed to evaluate the effects of heat strain on cognitive function among miners and to determine whether heat strain-related cognitive decline can be predicted by using more easily measured physiologic parameters in order for mines to minimize the risk of heat-related health.
