OBJECTIVES: This study aimed to examine the impact of extreme heat exposure frequency on inflammation and well-being in UK Fire Service personnel.

METHODS: 136 Fire personnel and 14 controls (CON) were recruited [92 Firefighters (FF), 44 Breathing Apparatus Instructors (BAI)]. BAI were split into low (LBAI; ≤15 exposures per month) and high (HBAI; ≥20 exposures per month) categories. Measures of inflammation, mood and fatigue were collected at 0, 3 and 6 month times points. These variables were analysed for differences between groups and association with frequency of exposure.

RESULTS: HBAI exhibited raised IL-1ß, IL-6, IL-10, IgE and lower IgM (p0.05).

CONCLUSION: High exposure firefighting consistently causes systemic inflammation without perceptual recognition of potential health risks.
