Smartwatch technology is significantly transforming health management and enhancing well-being. The technology capabilities in medicine have provided valuable tools for detecting, diagnosing, and managing chronic diseases, which have become a serious socio-economic burden worldwide. The adoption of these smart wearables offers significant advantages over traditional cuff-based methods. This study explores the significance of smartwatch technology and its inhibiting factors in managing hypertension. A systematic literature search was conducted in IEEE, Springer, Web of Science, and PubMed databases for studies published between 2021 and 2025. Twenty-four articles met the criteria for final inclusion. The findings reveal that smartwatch technology is effective in managing this chronic disease by providing continuous health monitoring, early detection, and medication adherence. However, factors such as perceived usefulness, perceived reliability, accuracy, privacy and regulatory issues, social influence and trust, cost and economic considerations, aesthetics and lifestyle fit need to be considered for effective adoption. There is a need for policymakers and healthcare practitioners to consider security implications and readiness concerns for the continued use of these technologies in managing hypertension.
