<p>A growing body of research has confirmed that nature plays a significant role in promoting human well-being. However, relatively fewer studies have explored whether living meaningfully (a form of eudaimonic well-being) draws people toward nature. Based on this, we conducted a weekly longitudinal study (7 time points, <i>N</i> = 309) using a random intercept cross-lagged panel analysis to investigate the relationship between nature exposure and both presence of meaning and search for meaning among emerging adults over time. Results showed positive associations at the between-person level between time spent in nature and both presence of meaning and search for meaning. At the within-person level, spending more time in nature was associated with enhanced presence of meaning, and increased search for meaning was linked to spending more time in nature. The above findings shed light on the complex dynamic relationship between nature and meaningfulness, highlighting that nature is not only a source of meaningful experiences but also a place proactively sought out in the search for meaning. In addition, this study deepens our understanding about meaning exploration among emerging adults and offers practical insights for interventions aimed at enhancing meaningful experiences.</p>
