Field Studies of Shiftwork: I. Temporal Patterns in Psychophysiological Activation in Permanent Night Workers

Abstract
The diurnal variation in body temperature, catecholamine excretion, performance and subjective alertness was studied among 24 permanent night workers during the 1st, 3rd and 5th day of their work week of 6 nights. Most of the variables showed a significant diurnal pattern with high values during work and the patterns of variation were similar during the 3 nights of measurement without any observable adjustment over the wk. Permanent night work might facilitate a more rapid switch over to night work after free days.
