No results posted yet for this study

Summary

The purpose of this study is to test whether shifts in the timing of the biological clock to a later hour (phase delay shifts of the human circadian system) can be produced in response to four successive evenings of light exposure, and whether that phase shift will result in greater evening alertness and greater nighttime sleep efficiency. Three different light sources will be compared: 1) standard fluorescent light; 2) blue-enriched light; 3) incandescent fluorescent light.
