This thesis approaches the analysis of self-assessment regarding the physical impact of computer games on players, considering key factors such as vision, diet, movement, reaction speed, etc. A total of 102 participants took part in the research, separated into different groups according to their gaming habits. Out of these participants, 19 individuals did not play computer games regularly and were therefore not included in the final results, ensuring a more precise analysis. The categorization of participants based on gaming intensity allowed insights into various ways computer games can affect players. This thesis provides a deeper understanding of the impact of computer games on players by analyzing key aspects such as vision, diet, movement, reaction speed, etc. Research results regarding the influence of video game playing encompass diminished vision and hearing, feelings of exhaustion, and experiences of pain after prolonged gaming. However, dietary habits, physical condition, and reaction speed are not significantly affected. These findings serve as a foundation for further educating players and parents about the importance of balancing computer game playing with maintaining healthy habits.
