This paper investigates the effects of positive thinking meditation on stress management of college students and assesses its potential in enhancing mental health and quality of life. An empirical analysis was conducted through a quantitative questionnaire survey method for college students majoring in film and television education at a university in Hainan. It was found that the frequency and duration of Positive Thought Meditation practice were significantly negatively correlated with stress levels, as well as significantly positively correlated with the variables of stress management, stress relief, anxiety and depression, and psychological health. These findings suggest that Positive Thinking Meditation may be an effective stress management tool that can help improve the quality of life of college students. The results of this study may provide a theoretical basis for promoting the practice of Positive Thinking Meditation in future educational settings, as well as providing a theoretical basis for more targeted psychological interventions for college students.
