Effectiveness of a Method of Evaluating the Clothing Comfort Sensation in a Perspiration State by Measuring Psychophysiological Responses

摘要

We measured the psychophysiological responses of participants wearing two kinds of undershirts made from hydrophobicfibers to investigate the sensation of clothing comfort. In the experiment, participants perspired following exercise. The perspirationincreased the humidity within the clothing, decreased the skin surface temperature, and worsened the comfort sensation. Multipleregression analysis revealed a stuffy sensation and a skin contact sensation as factors of the comfort sensation. Measurements ofphysiological responses revealed that the low-frequency/high-frequency ratio obtained from an electrocardiogram had high negativecorrelation with comfort sensation in the exercise/rest process. A difference in the moisture transport properties of the samples revealedthat participants discerned a stuffy sensation and cool sensation, and there is the possibility that the difference in the stuffy sensation ofthe samples can be evaluated by the CVRR, which is an index of parasympathetic nerve activity.
