The problem of the occurrence of stress in a person, its course and consequences attracts the attention of specialists in various fields of Science, from doctors to sociologists and psychologists. In recent years, on the applied aspects of Stress Research, the number of publications covering various aspects of human life has increased significantly. At the same time, not only conceptual, but even terminological unity has not yet been achieved. This led to an expansion of the conceptual apparatus, when the term “stress” began to be understood as a very wide range of phenomena, which is especially evident in the example of psychological stress. Many authors believe that the interpretation of stress is so diverse that it significantly complicates the development and adoption of measures to prevent and overcome excessive stress in practice. In addition, it causes terminological confusion among therapists, physiologists, and psychologists, complicating the interdisciplinary integration of medical, biological, and psychological sciences in human research.
