This study aimed to determine the differences between the effectiveness of Progressive Muscle Relaxation (PMR) and Slow Deep Breathing Exercise (SDBE) on BP of hypertension patients. The research was an experiment with a randomized pretest and posttest with three group design without a control group. The sample was 30 people with hypertension. The data were analyzed by univariate, bivariate and miltivariate. The results of the study showed a decrease in systolic and diastolic BP after the intervention to all groups. There was no significant difference on the effectiveness between the three groups after intervention. The optimal time of reduction in systolic BP in the PMR and SDBE groups occurred on day three. In diastolic BP, the optimal time of reduction did not occur. In conclusion, the three relaxation techniques effectively reduced blood pressure of hypertension patients. The effective time of blood pressure reduction occurred on the third day. The suggestion for patients from this study is the patients with hypertension can do the relaxation techniques Progressive Muscle Relaxation (PMR) and Slow Deep Breathing Exercise (SDBE) to lower the BP to close to normal.
