Abstract
In this work, a hybrid personal cooling suit incorporated with dry ice and ventilation fans (HYB), and a water-cooling suit (WCS) were chosen to examine actual cooling performance on mascot actors while performing a moderate activity at 34 °C & RH = 78%. The total trial duration was 60 min (40-min walking at 4.0 km/h followed by 20-min resting at room temperature [24 ± 1°C, RH = 55 ± 5%]). Results showed that both HYB and WCS successfully prevented the mascot wearers’ core temperature from rising above 38.0 °C during trials. In contrast, core temperatures of CON (i.e., no cooling) reached 38.0 °C in 35 min. Heart rates in HYB and WCS were decreased by 11 and 17 beats/min compared to that of CON. Perceptual responses have been greatly improved by wearing HYB and WCS. It was concluded that HYB and WCS could mitigate heat stress on mascot wearers during a performance in the studied condition.
