Hydrotherapy is a complementary system of medicine which uses the properties of water internally and externally for its therapeutic benefits. Various studies have demonstrated that hydrotherapy modalities positively influence autonomic nervous system regulation, reduce stress response, cardiovascular modulation and psychological health. Despite this certain hydrotherapy practices like neutral partial wet sheet packs remain unexplored in relation to specific clinical populations. Hence, given the evidence that hydrotherapy can serve as non-pharmacological adjunct, this study investigates the effect of neutral partial wet sheet pack on BP and HRV in hypertensive participants. AIM: This study aims to evaluate the effect of neutral partial wet sheet pack on forehead, neck and abdomen on autonomic variables in hypertensive individuals. OBJECTIVE: The objective of the study is to evaluate the immediate effect of neutral partial wet sheet pack on forehead, neck and abdomen on autonomic variables in hypertensive individuals. MATERIALS AND METHODS Participants: A total of 30 hypertensive individuals were recruited based on convenience sampling from a holistic health home, on the day of their admission during the stay. Design: The participants who showed interest in the study were screened using the predefined inclusion and exclusion criteria. Thirty eligible participants were selected, after which written informed consent was obtained, and were subsequently taken for experiment. Assessments: • SBP • DBP • Mean RR interval • Standard Deviation of NN intervals (SDNN) • Root Mean Square of Successive Differences (RMSSD) • Heart Rate • High Frequency • Low Frequency • High Frequency / Low Frequency Intervention: Participants in the study group were administered neutral partial wet sheet pack on forehead, neck and abdomen for a period of 20 minutes. Results: Thirty participants aged 35-75 years were assessed for HRV parameters and Blood Pressure before and after neutral partial wet sheet pack intervention. Significant improvements were observed in HRV parameters such as Mean RR, SDNN and Heart Rate indicating enhanced parasympathetic activity and autonomic regulation following the intervention. However, no significant changes were found in blood pressure and other HRV parameters such as LF, HF or HF/LF. Conclusion: Neutral partial wet sheet pack showed beneficial effects on cardiac autonomic modulation by enhancing parasympathetic activity in hypertensive individuals. Significant improvement was observed in selected HRV parameters while blood pressure changes were not statistically significant. These findings suggest its potential as a supportive non-pharmacological intervention for autonomic regulation.
