Wearable health monitoring devices have rapidly emerged as an important component of digital healthcare systems worldwide, driven by technological innovation, the growing burden of chronic diseases, and the need for continuous, patient-centered care. These devices, including smartwatches, fitness trackers, biosensors, and wearable medical monitors, enable real-time collection of physiological data such as heart rate, physical activity, sleep patterns, blood oxygen levels, and, in some cases, glucose and blood pressure. The objective of this article is to provide an overview of the global situation regarding the use of wearable health monitoring devices and to analyze their key advantages within modern healthcare systems. A narrative review and analytical synthesis of global trends, healthcare applications, and implementation experiences were conducted, focusing on clinical practice, public health, and healthcare system management. The analysis shows that wearable devices are increasingly integrated into preventive care, chronic disease management, rehabilitation, and remote patient monitoring. Their use supports early detection of health risks, improves patient engagement and self-management, and facilitates data-driven clinical decision-making. At the system level, wearables contribute to reducing hospital visits, optimizing resource allocation, and strengthening telemedicine services, particularly in aging societies and regions with limited access to healthcare facilities. Despite these advantages, challenges remain, including data accuracy, privacy and security concerns, regulatory differences across countries, and unequal access to digital technologies. In conclusion, wearable health monitoring devices represent a transformative tool in global healthcare by enhancing continuous monitoring, promoting preventive health behaviors, and supporting more efficient healthcare delivery. To fully realize their potential, coordinated efforts are required to improve data governance, interoperability, user education, and integration into clinical workflows, ensuring equitable and safe adoption across diverse healthcare settings.
