Heat tolerance of Fire Service Instructors

摘要

Objectives: Fire Service Instructors (FSI) experience repeated fire exposures a median of 13 +/- 8 times a month; consequently they may develop an acclimatised state. However, the chronic immunological implications of heat acclimation are yet to be understood. This study aimed to establish whether FSI exhibit an increased heat tolerance and altered immunological response to heat exposures, compared to non-exposed individuals. The study also aimed to identify if heat tolerance is related to symptoms of ill health.
