Effectiveness of Brain Dynamic Audio Stimulation for Improving Insomnia and Sleep Cycles in Healthcare Professionals: A Pilot Study

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.
