Online implementation of mind sound resonance technique for stress-related psychological and physiological outcomes in female homemakers: a controlled study

Background and Study Aim. Stress-related psychological and physiological strain represents a relevant concern in populations exposed to sustained domestic and caregiving demands. Yoga-based relaxation practices, including Mind Sound Resonance Technique (MSRT), have been applied in clinical and non-clinical contexts to support stress regulation in everyday life. Although such approaches are increasingly used, their application and short-term outcomes within specific sociocultural settings remain a matter of practical interest. Therefore, the aim of the present study was to examine the psychological and physiological outcomes associated with the application of Mind Sound Resonance Technique in female homemakers. Materials and Methods. A randomized controlled design was employed. Female homemakers were allocated to either an MSRT intervention group or an active control group receiving Progressive Muscle Relaxation (PMR). The intervention was delivered online over an eight-week period. Psychological outcomes included anxiety, sleep quality, and perceived stress. Physiological measures comprised resting heart rate, systolic and diastolic blood pressure, and respiratory rate. Assessments were conducted at baseline and post-intervention. Results. Participants in the MSRT group demonstrated greater improvements across psychological and physiological outcomes compared with the PMR group. Reductions were observed in anxiety (34.01%), sleep disturbance (37.54%), and perceived stress (37%). Improvements were also noted in resting heart rate (−12.07%), systolic blood pressure (−7.97%), diastolic blood pressure (−8.40%), and respiratory rate (−25.99%). All between-group differences were statistically significant (p < 0.001) and were accompanied by large effect sizes. Conclusions. When implemented in an online, home-based format, MSRT was associated with greater improvements in psychological well-being and physiological stress markers than an established relaxation comparator among homemakers. These findings support the practical applicability of MSRT as an accessible, low-cost stress-management strategy for populations facing barriers to conventional wellness services. Further studies are warranted to examine long-term sustainability and broader implementation across diverse settings.
