Physiological Temperature Thresholds and Heat-Related Hiker Assists: Preventive Search and Rescue in Grand Canyon National Park

Heat-related hiking emergencies in Grand Canyon National Park are frequent, leading to significant resource demands. Research indicates that physiological temperature thresholds play a critical role in these incidents. The Preventive Search and Rescue Team (PSAR) conducts around 750 hiker assists and 300 search and rescue missions annually. This study likely focuses on identifying specific temperature limits that trigger heat-related emergencies, providing crucial data for preventive measures. By analyzing physiological responses to heat exposure, the research aims to inform strategies that can mitigate risks and optimize resource allocation in search and rescue operations.
