The purpose of this study is to examine circadian rhythms in the home environment under three different lighting conditions: typical home lighting, candlelight and outdoor sunlight in the morning. The findings will provide important insights into how circadian rhythms can be measured outside of the laboratory and how morning light exposure influences circadian hormones.
