• The cardiac interbeat interval sequences and respiratory movement curves have been measured for 30 minutes under the six illuminance of 100,180,320,560,1,000 and 1,800 lx. The light sources used were fluorescent lamps with a color temperature of 4200 K. The temperature in the test room was kept at 24 ± 1℃. Spectral analysis of the cardiac interval signal showed the presence of the vasomotor component centered at about 0.1 Hz.The mean heart rate, mean amplitude of the vasomotor component and the ratio of the power of the vasomotor component to the total power (without D.C. component) were calculated from the cardiac interval signals. The mean respiratory period and depth were obtained from the records of the respiratory movement curves.They were found to be significantly responsive to 1/4 log unit in illuminance. The results suggested that the physiological load was minimum in the illuminance range from 500 to 600 lx, and increased prominently with an increase in illuminance from this range, while it increased only moderately with a decrease in illuminance.
