Change of flicker values according to seasons was studied on sixty healthy men, 18 to 38 years of age working in three 8-hour shifts under hot environment. Thermal conditions of the environment of the workshop were: in summer, air temperatures 28 to 40℃., relative humidities 80 to 85%, wind velocity 0 and in winter, 28 to 30℃, 75 to 80%, and 0, respectively. Followings are the summary of the results. 1) In the morning shift, ficker values before work are lower than those after work, in winter; on the contrary, in summer, such difference was not significant. In the night shift, values after work were lower than those before work in both summer and winter, especially in summer. 2) In each shift, the flicker values both before and after work were lower in summer than in winter. 3) Sleeping hours of these workers were shorter in summer than in winter. Therefore, the flicker value may be affected by the change of sleeping hours, temperature, and others.
