INTRODUCTION: Enhancing the well-being of urban school students is a growing challenge. The online mode of teaching during and post-pandemic era has increased students' daily screen time. As they spend more time indoors, they tend to disconnect from nature even more, adversely impacting their well-being. This study aimed to design and execute two well-being interventions-a positive psychology intervention (PPI) and a mindfulness-based intervention (MBI) in natural settings for urban school students in India. METHODS: One hundred eighty participants (aged 17-20) from a senior secondary school were randomly assigned to three groups: PPI, MBI, and a control group (CTR). Participants self-reported their levels of well-being, gratitude, inclusion of nature in self, sense of connectedness, resilience, awareness, perceived stress, and positive and negative emotions using a survey questionnaire at two times-pre- and post-interventions. Repeated-measures ANOVA was employed across time and groups, and RESULTS: Results indicate that both PPI and MBI interventions, when executed in natural settings, enhance student well-being, gratitude, inclusion of nature in self, sense of connectedness, resilience, awareness, positive emotions and decreased levels of perceived stress, and negative emotions. DISCUSSION: The study provides valuable insights for school authorities, policymakers, and urban planners to include natural settings in school premises and offer well-being interventions for students to connect with nature consciously.
