The purpose of the recommendations is to decrease as much as possible physiological, psychological and social problems connected with shift work. To achieve this goal working hours should be organized to take account of shift workers' tolerance to shift work. When recruiting new shift workers certain personal characteristics that make work in any shift work system inadvisable should be checked. As shift work can be considered to be an additional load, shift workers' health requires regular checking-up. If there are signs of health impairment, the workers should be removed from night shift work permanently or at least temporarily. The shift workers' free time should be arranged so as to facilitate recovery from shift work, especially after night shift. To decrease the workload during the night shift, if possible, workers should be given opportunity to take naps during work.
