Tissue temperature (T t) was continuously monitored by a calibrated multicouple probe during the 3-h immersions.T t was measured every 5 mm, from the longitudinal axis of the forearm to the skin surface. Skin temperature, rectal temperature, and blood flow ( $$\dot Q$$ ) were also measured during the immersions. The maximum rate of change of the forearm mean tissue temperature ( $$\dot T_{{\text{t, max}}}$$ ) occurred during the first 5 min of the immersion. $$\dot T_{{\text{t, max}}}$$ was linearly dependent onT w (P<0.001), with mean values (SEM) ranging from −0.8 (0.1) °C · min−1 at 15°C to 0.2 (0.1) °C · min−1 at 36°C. The maximum rate of change of compartment mean temperature was dependent (P<0.001) on the radial distance from the longitudinal axis of the forearm. The half-time for thermal steady state of the forearm mean tissue temperature was linearly dependent onT w between 30 and 36°C (P<0.01), with mean values (SEM) ranging from 15.6 (0.6) min at 30°C to 9.7 (1.2) min at 36°C and not different between 15 and 30°C, averaging 16.2 (0.6) min. There was a significant linear relationship between the half-time for thermal steady-state of the compartment mean temperature and the radial distance from the longitudinal axis of the forearm for each value ofT w tested (P<0.001). The data of the present study suggest that the forearm $$\dot Q$$ is an important determinant of the transient thermal response of the forearm tissue during thermal stress.
