This study investigated the transient effects on human thermal responses of clothingadjustments. Two different levels of activity were tested, and the temperature was set to resultin a warm or cool thermal sensation at each activity level. The subjects (12 females and 12males) wore identical uniforms and were asked to take off or don a part of the uniform afterthey had adapted to the experimental conditions for more than 20 min.Independent of the activity level, the thermal sensation votes responded immediately to theadjustment of clothing insulation and reached a new steady-state level within 5 min after bothup-step and down-step of clothing insulation. It was similar to stepwise changes oftemperature and humidity except that the thermal sensation vote after down-step of clothinginsulation did not overshoot obviously.
