In determining the state of human health, methods of empirical research and modern computer technologies are used. Nowadays, the science of valeology is developing, where human health is considered as a harmonious combination of physical, mental, emotional, intellectual, social, environmental and spiritual health. The Department of valeology in V.N. Karazin Kharkiv National University developed a system of diagnosis of health, which allows you to monitor the state of the body from the cellular level, the level of systems and organs, to the level of energy component, as well as to determine the psycho-physiological and adaptive characteristics of the body. Monitoring is carried out with the help of instrument - computer software systems, developed on the basis of the latest achievements of science and technology, based on modern ideas about man as a complex material and energy-information structure. The diagnosis system is noninvasive, which makes it possible to use it in children's and student groups in the pedagogical process, as well as to determine the level of health and correction of post-traumatic syndrome.
