Background: Sleep disturbances are increasingly recognized as a major public health concern due to their negative impact on physical and psychological health. Non-pharmacological interventions have gained attention as sustainable alternatives to medication-based sleep management.
Objective: This study aimed to examine the effect of neuromuscular relaxation (NMR) on sleep quality by evaluating changes in individual components of the Pittsburgh Sleep Quality Index (PSQI). The study also explored the role of adherence and selected demographic factors in shaping sleep-related outcomes over time.
Methods: A prospective interventional study was conducted among adults with self-reported poor sleep quality. Participants engaged in NMR sessions three times per week for a duration of three months. Sleep quality was assessed using the PSQI at baseline and after completion of the intervention, with monthly follow-up assessments. Statistical analyses were performed to evaluate pre- and post-intervention changes, adherence effects, and demographic influences.
Results: Significant improvements were observed across all PSQI components following the intervention. Greater adherence to NMR sessions was associated with more pronounced improvements in sleep latency and sleep duration. Progressive enhancement in sleep quality was noted over the three-month period. Certain demographic characteristics, such as age and body mass index, showed modest associations with the magnitude of improvement.
Conclusion: Neuromuscular relaxation appears to be an effective non-pharmacological approach for improving multiple dimensions of sleep quality. Regular participation enhances outcomes, supporting the potential role of NMR as a safe and accessible intervention for individuals experiencing poor sleep.
