The Role of Motivation to Excel in the Etiology of Exertional Heat Stroke.

Abstract

Exertional heat stroke (EHS) is a medical emergency characterized by elevated body temperature and central nervous system dysfunction, and it can include dizziness, confusion and loss of consciousness, as well as long-term organ and tissue damage. EHS is distinct from classic, or passive, heat stroke and is most commonly observed during intense physical activity in warfighters, athletes, and laborers. EHS is an ongoing non-combat threat that represents a risk to both the health and readiness of military personnel. Potential risk factors and their mitigation have been the subject of investigation for decades. One risk factor that is often mentioned in the literature, but not well quantified, is that of individual motivation to excel, wherein highly trained military personnel and athletes exert themselves beyond their physiological limits because of a desire to complete tasks and goals. The motivation to excel in tasks with high standards of achievement, such as those within elite military schools, appears to create an environment in which a disproportionately high number of exertional heat illness casualties occur. Here, we review existing biomedical literature to provide information about EHS in the context of motivation as a risk factor and then discuss five cases of EHS treated at Martin Army Community Hospital at Fort Moore, GA, from 2020 to 2022. In our discussion of the cases, we explore the influence of motivation on each occurrence. The findings from this case series provide further evidence of motivation to excel as a risk factor for EHS and highlight the need for creative strategies to mitigate this risk.
