| Abstract |
The effects of distribution of rest days in 12 hour shift systems were investigated. An abridged version of the standard shiftwork index which included retrospective alertness ratings was completed by a large sample of industrial shiftworkers. The respondents worked 12 hour shift systems that either did or did not incorporate breaks of >24 hours between the blocks of day and night shifts. Systems which incorporated rest days between the day and night shifts were associated with slightly higher levels of on-shift alertness, slightly lower levels of chronic fatigue, and longer sleep durations when working night shifts and between rest days. Early changeovers were associated with shorter night sleeps between successive day shifts, but longer and less disturbed day sleeps between night shifts. The distribution of rest days in 12hour shift systems had only limited effects on the outcome measures, although the few modest differences that were found favoured systems which incorporated rest days between the day and night shifts. Topics: fatigue; questionnaire survey; shift work; sleep; social aspects; state of health; vigilance; work-rest schedules. |
