The article examines the problems of digital competence as a phenomenon of modern life, especially aggravated in connection with the COVID-19 pandemic. Digital competence as the latest concept, skills necessary for the modern, connected with the scientific and technical implementation of new technologies in education, economy, politics and production. The development of digital literacy concepts relies on both traditional and diverse media. However, the main difficulty in its development is associated with the digital divide, overcoming which depends on many factors. In the educational environment, digital competence should take into account the age-related physiological, mental and psychological characteristics of schoolchildren, and in preparation for professional activity-support for professional digital competence.

The article examines the problems of professional self- development among undergraduates in the digital space, identified during the COVID-19 pandemic. The results of the study showed that students have characteristics that are necessary for further personal growth. They want to know themselves and ready to change and learn new things, improve themselves. Conducted during a pandemic and distance learning in self- isolation showed that 50% of students expressed satisfaction with this form of education, explaining their opinion with a high level of independent search for the necessary information, opportunities for self-development, self-realization, and self-improvement. Among the difficulties of distance learning, all surveyed identified: search and critical analysis of digital information; communicative dissatisfaction, the need for approval. The surveyed students in their self-development need a micro- and macro- environment that would create a secure creative educational space. It is necessary to search for new solutions to overcome psychological barriers associated with the need for self-development as future highly qualified specialists in the context of modern trends in the development of digital education.

The study of the social health of labour resources as human capital is an actual problem. In production workers, the vegetative status was studied in terms of heart rate variability. By the concept of autonomic reactivity A.M. Greenberg, the results of the study found that the vegetative status of male employees and workers differs. The employees performing functions related to the organization of the production process showed general sympathicotonia. Workers performing specific production tasks have a general sympathicotonia. The results of the study found that vegetative status makes it possible to assess the social health of production workers. In the context of the intensive introduction of neural networks and nanotechnology into industrial production, the number of employees will increase. As a result, there will be an increase in the likelihood of cardio- respiratory system diseases among this contingent of workers. This will entail the development of corrective programs for the prevention of diseases of the cardiovascular system, and the introduction of changes in the classifier of occupational diseases.
