This study examines daily emotion regulation strategies of young adults aged 20-30 and proposes design opportunities for enhancing emotional well-being. Research with 29 participants revealed a preference for behavioral strategies (73.4%) over cognitive strategies (26.6%), particularly “Seek pleasure or relaxation” strategies. Significant differences were observed between positive and negative emotional contexts. Four main categories of emotion regulation strategies were identified: Disengagement, Seek pleasure or relaxation, Reallocate resources, and Engagement. Design opportunities were proposed based on these findings. This study enhances understanding of young adults’ emotion regulation and offers design strategies for product development. Future research should validate these strategies and explore personalized approaches, considering long-term impacts and ethics.
