The purpose of this study was to measure the rate of perspiration due to light physical exercises, and to measure its effect on skin electrical conductivities related to meridian autonomous nervous excitation. The adopted exercise were 10 to 15 minute bicycling and two kinds of 10 minute qigong exercises. The experiment was carried out both in winter and summer under fixed temperature values. Our findings were as follows: 1. With the room temperature 18.9 ± 2.0℃ in winter, each of a 10 minute bicycling and qigong exercises caused a low rate of perspiration. It had, however, no effect on the skin electrical conductivities. 2. With the room temperature 25℃ in summer, the rate of perspiration due to bicycling was 0.7〜0.8mg/cm^2/min, and was about two times as high as that in winter. Its effect on the electrical conductivities was again negligible. 3. With the room temperature 28℃ in summer, the rate of perspiration due to bicycling was 1.3〜1.8mg/cm^2/min, and had an apparent effect on the conductivities. 4. The change of the conductivities caused by a high rate of perspiration was similar to that of the case in which the hands and feet of the subject were moistened with a 1% solution of salt. 5. The probable reason why the lower rates of perspiration did not change the measured values of the conductivities was that the electrode which contacts the skin points was always sufficiently moistened and that the moisture of the electrode masked the effect of the skin moisture due to perspiration.
