The aim of this study was to investigate the relationship between how young people spend their leisure time and their mental health. The focus was on understanding how different leisure activities, including the use of digital media, affect the emotional well-being of young people. The theoretical part of the paper includes an overview of key concepts and theoretical frameworks related to leisure time and mental health, as well as a review of existing research on similar topics. The research methodology involved quantitative analysis of data collected through a survey questionnaire consisting of 21 questions.The results showed a statistically significant difference between demographic characteristics (age and gender) of the respondents and their satisfaction with the amount of leisure time. It also indicated that there was no statistically significant difference between the gender of respondents and their satisfaction with managing leisure time, but there was a significant difference between age and satisfaction with managing leisure time. Additionally, a correlation was observed between the amount and manner of using leisure time, as well as the amount of time spent using digital media and/or social networks with the mental health of respondents.The findings suggest that balanced use of leisure time, with an emphasis on social and physical activities, can contribute to better emotional states among young people. These results provide a basis for further research and interventions aimed at improving the mental health of young people through changes in how they spend their leisure time.
