The integration of digital health technologies, particularly wearable devices, into preventive healthcare and health system management represents a paradigm shift from reactive treatment to proactive wellness. This article explores the multifaceted impact of these technologies, analyzing their role in continuous physiological monitoring, personalized health feedback, and population-level data analytics. The primary objective is to examine how wearables and associated digital platforms influence individual health behaviors, clinical decision-making, and the operational efficiency of healthcare systems. The method involves a comprehensive narrative review of current literature, synthesizing evidence on wearable adoption, data integration challenges, and implementation frameworks within diverse healthcare settings. Results indicate that wearable technologies significantly enhance patient engagement in preventive practices, such as physical activity promotion and chronic disease management, by providing real-time, actionable insights. For health system management, these devices facilitate remote patient monitoring, potentially reducing hospital readmissions and enabling more efficient resource allocation through predictive analytics. However, critical challenges persist, including data privacy concerns, algorithmic bias, inequitable access leading to a "digital divide," and the need for robust regulatory and interoperability standards to integrate wearable data into electronic health records effectively. The conclusion underscores that while wearable technologies offer transformative potential for decentralizing and personalizing care, their successful integration into preventive healthcare and sustainable health system management requires coordinated efforts in policy development, clinical validation, and ethical governance to ensure equitable, secure, and effective use.
