Abstract
BACKGROUND: Hypertension is a chronic condition that progressively worsens. Lifestyle modifications and antihypertensive medications are among the strategies recommended to manage it. Nonpharmacological interventions like deep relaxation, Aum Kara chanting, and tuning have been found to help lower blood pressure, enhance cardiovascular function, reduce stress, and promote mental tranquility. This study examines the effects of Aum Kara and the deep relaxation technique (DRT) on autonomic variability in individuals with primary hypertension.
METHODS: From a pool of 200 individuals screened for hypertension at SDM Hospital in Dharmasthala, 60 participants aged 25-50 were selected according to the study's inclusion and exclusion criteria. The enrolled participants were assigned to one of two groups: group 1 (DRT) or group 2 (Aum Kara) based on randomization tables. Each group underwent a 20-minute session, after which their data were evaluated.
RESULTS: Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) decreased immediately after the interventions in both groups. The Aum Kara group demonstrated a decrease in heart rate and the LF/HF ratio compared to the DRT group (p < 0.05). Specifically, in the Aum Kara group, LF decreased and HF increased, showing statistical significance in comparison to the DRT group. A significant difference was noted in all HRV components between the groups upon comparison.
CONCLUSION: In the comparison of the two therapies' effects, Aum Kara chanting demonstrated a more significant immediate beneficial impact on the sympathovagal system balance compared to DRT.
