Numerous previous studies show the positive effects of regular exercise on mental health and the quality of sleep. However, it is not clear whether such effects would be applicable to the population with poor vocational and overnight working conditions. Therefore, in this study, the effects of regular exercise activity on sleep quality and mental health among sanitation workers were examined. A total of 18 sanitation workers were randomly assigned to either an experimental group (n=9) or a control group (n=9). Then, 12-week physical activity program was applied to the experimental group. The result can be summarized as follows. First, quality of sleep and the happiness factor of mental health showed significant differences between the pre- & post-test periods. Next, there were significant interactions among the conditions, test periods in the quality of sleep and all the mental health factors. Regular physical activity was, also, shown to be an effective intervention for quality of sleep and mental health. Further, this beneficial aspect of physical activity can be applied to the people such as public cleaners or caretakers who are working in demanding and harsh conditions.
