This document discusses a study on the potential of self-monitoring and self-tracking for health promotion. The study explored the experiences of self-trackers through an online survey and interviews. Key findings included that self-trackers engaged in tracking for self-knowledge, curiosity and health optimization. While self-tracking provided benefits like empowerment and motivation, barriers included issues with data interpretation and consistency. Overall self-tracking improved self-awareness and informed decision making for health, though future research should explore long term impacts and how to better integrate these tools into healthcare.
