Characteristics of shiftwork schedules can have distinct impacts on workers'sleep.
This report presents comparisons of the effects of two different shiftwork schedules on duration and quality of the main sleep episodes in comparable worker populations at two different petrochemical plants.
No significant differences were found for sleep duration in comparing the two plants.
However, within each plant's shift cycles, morning and night shifts showed shorter sleep durations than all other workdays and days off.
Quality of sleep was perceived as lowest for night shifts of both plant schedules, and of lesser quality for weekly than for fast-rotating shifts.
These results support recommendations for reducing the number of consecutive nights of shiftwork.
However, before recommending any optimal shift schedule, interactions of sleep duration and quality with shift schedules need much further evaluation.
