In this review the results of physiological and psychological studies related to night and shift work have been collected and were discussed mainly from the standpoint of their usefulness in industry as they aid in understanding the problems of shift work, the sources of possible troubles and complaints connected with shift work, and in the alleviation of these problems. Topics included: circadian rhythm of biological functions and night work dealing specifically with the effect of night work on circadian rhythms and circadian periodicity; physical work with emphasis on the role of some factors in energy transformation during physical work in the day and at night, the day/night variations in ventilatory capacity and circulatory functions, results of fitness and orthostatic tests in the day and at night, and day to night variations in physiological responses to prolonged physical effort; the effects of night and shift work on mental, sensory motor, and manual performance; day to night variations in physiological responses to heat stress; the importance of sleep and rest for shift workers; and social problems of shift workers and organization of the night shift with special attention given to reasons for preference of various work shifts, various types of shift systems, and organization of breaks within the night shift. An addendum reviewed recent studies on the physiological aspects of circadian variations in glucose tolerance, circadian variations in physiological reactions to physical work, and the influence of physical exercise on circadian variations in 17- KS urinary excretion.
