Comparative assessment of changes in the psycho-physiological indicators of the organism resulting from desynchronosis

Prolonged reliance on administrative time, rather than natural (solar) time, alters the human body and can negatively affect the psychophysiological health of children and adolescents. Our research aims to assess the psychophysiological state of schoolchildren in regions where geographic time does not align with administrative time. A study of ۲۰۰ students in grades ۹–۱۰ was conducted in two region to compare how  desynchronosis affects their psychophysiological state. The regions differed in the gap between official and natural time: in one region, the difference was ۴۵ minutes, and in the other, it was ۱ hour and ۳۰ minutes. In the study, participants completed a questionnaire that included socio-demographic information, characteristics of sleep and wakefulness, items from the adolescent-adapted Horne–Östberg questionnaire to determine chronotype, and questions on their subjective experience of forgetfulness and emotional state. In addition, the “NS Psychotest” computer system was used to obtain objective measures of cognitive functions and attention. Current data show that the interrelationships among sleep duration, chronotype, and social jetlag in adolescents systematically affect academic achievement and cognitive functioning. These findings highlight the need to reconsider institutional parameters of the education system (such as school start times and study load) from a biologically grounded perspective. The results highlight the importance of considering regional chronobiological characteristics when organizing the educational process.
