Heat stroke burden and validity of wearable-derived core temperature estimation during elite military training.

Objectives: Exertional heat stroke (EHS) remains a significant health concern while training in hot environments, prompting the development of noninvasive wearable technology for monitoring estimated core temperature (ECT). The objective of this study was to review the effectiveness of an ECT device during elite military training by providing a case series of individuals who developed EHS.

Methods: This is a retrospective study of EHS cases during high-intensity training while wearing the ECT device, Zephyr Bioharness.
