Firefighter stress response similar to 'overtrained athletes'

Repeated exertion could leave a legacy of poor health, shows study

The stress of firefighting can unleash an inflammatory response that puts individuals at risk of poor health with repeated exposure, Australian researchers warn.


In a novel study, researchers tested the release of pro-inflammatory cytokines among 38 volunteer bush firefighters after a 12-hour shift, finding interleukin-6 and interleukin-8 were significantly increased.
