Some problems of night and shift work: Is the physiological cost of long-lasting standard work the same at night as

Abstract:
Physiological reactions to long-lasting physical work performed at different times of day were measured in 20 healthy men. Circadian variations in physiologic variables have been shown which indicated higher physiological cost, of night work. The conclusions providing the base for establishing the criteria and guiding principles for shift work are discussed.
