Abstract: Approximately 30% to 40% of adults suffer from some form of insomnia in any given year. Insomnia related productivity losses for organizations are estimated at $5 billion dollars annually. This is a problem, especially common for nurses and healthcare workers.  Long work weeks, shift work, and high workload have been linked to poor sleep quality. Currently, there is a gap in research on how exercise affects quality of sleep among nurses who work 9 hour or longer night shifts. Previous research has shown that exercise has an effect on sleep processes. The study will test the hypothesis that high workload will decrease nurses’ quality of sleep, and high levels of exercise will improve sleep quality. Further, it is hypothesized that high workload will have a negative impact on exercise behaviors. It is also predicted that exercise will partially mediate the relationship between high workload and quality of sleep. Finally, it is predicted that exercise will moderate the relationship between high workload and quality of sleep, meaning that high levels of exercise will improve nurses’ quality of sleep more so than low levels of exercise. The hypotheses will be tested using a subset of 98 nurses from an archival data set.
