Abstract
Daytime showering was an additional measure to increase heat-related illness prevention effectiveness in the RTA recruit training program, but the appropriate duration of taking a shower was doubtful. This retrospective cohort study aimed to compare the body temperature change from different shower duration in the RTA recruit training program. The data were taken from 277 conscripts of three training units. The length of time when taking a shower was recorded from entering to leaving the bathroom and the change of body temperature was calculated from the pre-bath temperature minus the post-bath temperature which was measured by a thermometer. The difference in temperature change was analyzed from the duration of showering.
The results showed that the samples were all male and 93.50% of them were 21 - 22 years old and 68.23% of the subject had normal body mass index (BMI). Any shower duration decreased the body temperature. The maximum temperature change was 0.45 ± 0.14 Celsius when taking a shower for thirty-five minutes, and minimum temperature change was 0.03 ± 0.20 Celsius in five minutes of taking a shower. Every duration of showers demonstrated a significant statistical difference of body temperature change (p < 0.05) except for the 5 - 10 minutes and 20 - 25 - 30 minutes of showering. Lastly, shower duration affects body temperature change so further study needs to show a clear result for proper application.
