Fatigue is indicated as a factor in occupational accidents and diseases and it can reduce individual efficiency. In shift workers who experience sleep disturbance، the occupational accidents and diseases occurring can be aggravated by fatigue. The present study aims to investigate the fatigue intensity and its relationship to insomnia severity among employees of Tehran rolling and steel production company. This descriptive analytical study had been done among 180 workers of the mentioned company. Data collection was done by face-to-face survey method and using the standard questionnaires. Results showed that the fatigue score among fixed-dayshift and rotating-shift workers was 6 and 7 respectively and fatigue level for both groups was 4. In all symptoms associated with fatigue average score of rotating-shift were higher than dayshift and there was a significant difference between them. Relationship between the symptoms of fatigue with Insomnia Severity Index was significant. Warehousing received the highest scores of fatigue and severity of insomnia between different tasks under study. Our findings indicate that level of fatigue and severity of insomnia among workers of industry is very high. Since this can lead to the occupational accident and reduction efficiency، it is necessary to provide facilities for personnel such as reducing working hours، doing regular rest and exercise during working time، paying sufficient attention to humanitarian needs and improving work system.

Chronic insomnia is a common complaint of hemodialysis patients.

This study is a before and after quasi-experimental study. using purposive sampling method 42 patients were selected. Data collected by insomnia severity index (ISI) and two-week sleep diary that were completed before and after relaxation.

Data were analyzed with t-test، willcoxon، macknemar، pearson and spearman tests. More samples are female (54. 5%)، marreid (60%) and house keeper (54. 2). mean age of samples are 42. 83±12. 85 and mean hemodialysis history were 4. 97±4. 54.
