Abstract
A comprehensive study of the effects of shift work and job duties on sleep was conducted. More than 1600 workers from 17 international unions were surveyed. Aspects studied included adaptation to shift work, shift worker sleep strategies, the relation of body temperature to sleep length, sleepiness, and mood, and the relative importance of subjective criteria for judging sleep quality. Models were developed for research approaches for the analysis of sleep. Family and social problems were increased in night workers. Night work resulted in significant decreases in the main sleep length period which did improve over time. Body temperature could not be used as a predictor of sleep length, sleepiness, or mood. Significant performance decrements resulted from permanent night work. Workers suffered from chronic sleep deprivation. Napping did not provide sufficient compensatory function and resulted in more disturbed main sleep periods. No differences were seen for age, sex, or job function. The author concludes that this is a complex problem area in which it is very important to collect data from real worker populations in a real work environment.
