Clinical Trial Summary

The study will recruit 60 participants aged 60 and above, who suffered from insomnia for at least 3 months. Sleep parameters and chronotypes assessed with questionnaires and actigraphy, daytime sleepiness, and biological rhythm (dim light melatonin onset) will be measured. The intervention involves light exposure using a prototype device developed by GCSOL Tech Co., Ltd., a company with expertise in light therapy research and development. Three conditions will be tested (1) bright light; (2) near-infrared light; (3) bright light+ near-infrared light. Data analysis will employ paired t-tests to compare sleep parameters and dim light melatonin onset before and after treatment. Kruskal-Wallis tests and multivariate linear regression will be used to examine differences between intervention groups, controlling for gender and age. Safety analysis will include monitoring adverse events.
