摘要：(1) Background: Well-being is a broad concept within which, among other components, self-esteem and general mood can be distinguished. Their formation can take place on the basis of contact with physical activity and with the natural environment. (2) Methods: The aim of the study was to compare the self-esteem and general mood of schoolchildren at different levels of contact with physical activity and the natural environment, distinguishing between active outdoor, active indoor and inactive groups. The study involved 306 secondary school students aged 16–19 years. The study used a diagnostic survey method, choosing a questionnaire technique. Two research tools in the form of survey questionnaires were used: Rosenberg Self-Esteem Scale—SES and General Mood Scale—GMS. (3) Results: The results indicated physical activity as an important determinant of both well-being components studied. In the study group of adolescents, contact with the natural environment proved to be a non-significant determinant of well-being. (4) Conclusions: The hypothesis of a synergistic positive effect of physical activity and contact with nature on self-esteem and general mood, which was not confirmed in this study, should be verified among representatives of older age groups.
