This paper presents an analysis of Russian scientific research in the field of the chronobiological potential of human resources as a condition for ensuring socially safe activities in the development of the North. The analysis of literary sources revealed that mainly works are devoted to characterization, including comparative, of individual physiological indicators. Most of the literature studied on the problems of human adaptation to the conditions of the north is devoted to the study of the functional state of the physiological systems of the indigenous and alien population to the harsh climatic conditions. Extreme north of the European, West Siberian, and less, East Siberian part of Russia. In connection with the development of natural resources, where there is no permanently resident population, such a non-traditional form of labor as a shift began to be used effectively. The time of the watch is determined by the conditions. Since newcomers will take part in the development of the Arctic latitudes, it is extremely important, from this point of view, information about seasonal exacerbations of functional systems of a pathological nature and disorders of the circadian chronorhythms of melatonin production resulting from changes in photoperiodism. In the analyzed works it is emphasized that the obtained information about the adaptation resources of various labor groups operating in the development of the Arctic latitudes, testifies not to the benefit of their health in comparison with the genetic potential of Aboriginal people. The results of the analysis of literary sources showed that the study of the potential of the human body from the point of view of determinism is not enough, since we can only register linear indicators. A look at this problem of the chronobiological potential of human resources from the point of view of fractal determinism is not well understood. © Published under licence by IOP Publishing Ltd.
