The purpose of this study is to examine, in healthy controls, whether LED lighting that has a color spectrum similar to that of sunlight is able to differentially impact mood, circadian rhythms, sleep, and behavior, as compared to standard fluorescent lighting.
89 studies on the registry are indexed under Chronobiology Disorders; 21 are open to participants now.
This study's enrollment of 10 is below the median of 65 across 58 interventional studies indexed under Chronobiology Disorders.
