The purpose of this study is to determine differences in physiological recovery between two consecutive days of simulated fire suppression work. The secondary purpose is to determine differences in heat gain and heat loss between two consecutive days of simulated fire suppression work. Subjects will complete two consecutive days of simulated structural firefighting shift work, 24 hours apart. Before and after each laboratory visit, subjects will continuously wear a Holter monitor and ambulatory blood pressure monitor to quantify parasympathetic tone and recovery from work.

Exclusion Criteria:
Subjects will complete 2 consecutive days of simulated firefighting tasks in the heat. The simulated work consists of 20 minutes of simulated structural work in a hot environment, followed by 20 minutes of seated rest in a temperate room, mimicking a typical recovery period in structural firefighting. Subjects then re-enter the environmental chamber and complete 23 minutes of simulated overhaul work in a temperate environment.
Other: 2 days of work heat stress
2 consecutive days of identical simulated structural firefighting tasks.
