Considering that the galvanic skin resistance, which is believed to indicate sensitively the central excitation or the functions of sympathetic nerves, should be kept openn for further studies as one of the indicators of the labour strain, the authors investigated the patterns of changes in the galvanic skin resistance by time lapse in the static and in the active working state. The results thus obtained are roughly as follows :<BR>(1) The galvanic skin current in the static state showed a relatively larger diversion compared with the puls rate, skin temperature etc. However, it never showed any fixed correlation with skin temperature, puls rate, sex, age, fat or slender.<BR>(2) The absolute value of the galvanic skin current in the active working state demonstrated a tendency of reduction as the intensity of work becomes higher. However, in the observation of its changes by time lapse, a tendency of reduction was usually observed when the intensity of work was lower than the limit of the establishment of a steady state, and a tendency of gradual increase was usually observed when the intensity of work was higher than the limit. Furthermore, a tendency that the rate of increment. of the galvanic skin current in such cases well indicate the labour strain.<BR>(3) The demonstration of the distress induced by a static work or the labour strain with the galvanic skin current is considered inadequate.
