# Effects of Binaural Beat Music Integrated with Rhythmical Photic Stimulation on Anxiety Reduction among Healthy Daycare Center Staff

## TL;DR

This study explores how combining binaural beat music with rhythmic light stimulation helps reduce anxiety in daycare staff.

## Contribution

The novel contribution is demonstrating that integrating binaural beat music with photic stimulation significantly reduces anxiety in individuals with moderate anxiety.

## Key findings

- BBM with photic stimulation significantly reduced the nLF/nHF ratio in participants with moderate anxiety.
- The intervention showed potential for regulating the autonomic nervous system to relieve anxiety.
- Results suggest a promising non-pharmacological approach for anxiety prevention and relief.

## Abstract

This study investigated the efficacy of combining binaural beat music (BBM) with rhythmical photic stimulation at the α frequency in alleviating anxiety among daycare staff and explored its impacts on daycare staff with different anxiety levels. A quasi-experimental research design was adopted, which included three interventions: BBM, BBM integrated with rhythmical photic stimulation, and relaxation music (control group). Participants completed a questionnaire prior to the first intervention, which included personal demographic information and the Beck Anxiety Inventory. The effects of these interventions on anxiety relief among daycare staff were evaluated through heart rate variability (HRV), brain waves, and blood pressure before and after the interventions. Statistical analysis primarily employed the Friedman test to analyze the differences in changes in HRV, brain waves, and blood pressure before and after the interventions. A total of 40 individuals participated in this study (16 males and 24 females), with an average age of 31.73 ± 8.83 years. The results showed that, compared to BBM alone, BBM integrated with rhythmical photic stimulation significantly reduced the normalized low/high frequency (nLF/nHF) ratio in participants with moderate anxiety (p < 0.05). The results suggest that BBM integrated with rhythmical photic stimulation may serve as an intervention for the prevention and relief of anxiety by regulating an individual's autonomic nervous system. However, further research is required to confirm these findings.
