About the trial
What the trial wants to find out
This study aims to evaluate the effectiveness of Brain Dynamic Audio Stimulation (BDAS) in improving sleep quality among healthcare professionals experiencing insomnia. Healthcare workers are frequently exposed to high occupational stress, irregular work schedules, and sleep disturbances, which may adversely affect mental well-being, cognitive performance, and clinical care.

Participants will use BDAS once daily for 30 minutes over a two-week period under standardized conditions. Both subjective and objective sleep-related outcomes will be assessed. Subjective sleep quality will be evaluated using the Insomnia Severity Index (ISI). Objective sleep parameters will be derived from short-duration EEG-based sleep recordings, including measures of sleep onset, sleep efficiency, and sleep stage distribution based on standardized scoring criteria.
This study seeks to determine whether audio-based neural entrainment through BDAS can facilitate sleep initiation and improve sleep efficiency in a real-world healthcare setting. As a non-pharmacological and non-invasive intervention, BDAS may offer healthcare professionals a safe and practical approach to managing insomnia and supporting overall well-being.
The group in the trial
- Brain Dynamic Audio StimulationTreatment being tested
Participants in this experimental arm will receive Brain Dynamic Audio Stimulation (BDAS), a non-pharmacological auditory intervention designed to support sleep initiation and improve sleep quality. Each participant will use BDAS for 30 minutes once daily over two consecutive weeks in a controlled environment within Chi Mei Medical Center. The intervention will be delivered in a quiet and private setting to minimize external disturbances and ensure standardized conditions across sessions. The audio stimulation consists of frequency-modulated sound patterns intended to facilitate relaxation and support sleep onset. Pre- and post-intervention assessments will include the Insomnia Severity Index (ISI) as a subjective measure of sleep disturbance, as well as short-duration EEG-based sleep recordings. Objective sleep-related outcomes will be derived from EEG data, including sleep onset, sleep efficiency, and sleep stage distribution, in accordance with standardized sleep scoring criteria
