In order to evaluate sauna suit experimentally, wear tests on two different clothing ensembles were conducted using thirteen healthy female students as subjects. The two different clothing ensembles were vinyl sauna suit and cotton undersuit ensemble (S+C) and cotton undersuit ensemble (C). The experiment was carried out under two thermal conditions : 24℃, 50%RH and 30℃, 60%RH in a climatic chamber. Total sweat rate (TSR) and sweat rate absorbed in clothing and remaining on skin (N-ESR) were measured in the experiment. Skin temperature, temperature and humidity inside clothing and subjective sensations were also determined throughout the experimental course.
In the case of 30℃ wearing sauna suit showed larger sweat rates. But this resulted from much larger N-ESR and from smaller evaporated sweat rates (ESR). On the other hand, the TSR measured did not show any difference between the two clothing ensembles in the case of 24℃. However, the same patterns as observed at 30℃ were found in both the N-ESR and the ESR. Higher skin temperatures and temperatures and humidities inside clothing were measured in both thermal conditions wearing S+C. The findings seemed to be coincident with the behaviour on perspiration mentioned above.
