Practicing holding a handgrip is a non-pharmacological therapy for treating hypertension because it stabilizes blood pressure and heart rate. Many combination therapies are used, including combining handgrip exercises with sound waves. Natural sounds will stimulate the hypothalamus, resulting in a feeling of calm and have an effect on the blood pressure regulation mechanism. The aim of this study was to determine the effect of a combination of handgrip exercise and natural sounds on the blood pressure of clients with hypertension. This research method is a pre-experimental one group pre and post test design and sampling using purposive sampling technique. The population of this study were clients who were recorded as suffering from hypertension at the Sekaran Semarang Community Health Center. The research instrument uses a digital spygmomanometer and SOP for action. The research stages consist of preparation, implementation and processing of research data.
