A study conducted by the Lighting Research Center at the Rensselaer Polytechnic Institute and published in the International Journal of Endocrinology indicates that exposure to short-wavelength light can potentially help adolescents be better prepared for the challenges they face throughout the day and can also help them deal with stress.
Adolescents, who are chronically sleep deprived, were tested in three overnight sessions, at least a week apart. During the sessions, the teens were given a window of 4.5 hours to sleep and then were either subjected to morning short-wavelength blue light upon wakening or were left in dim light. The study showed that the subjects who were exposed to the short-wavelength blue light significantly enhanced their cortisol awakening response (CAR), which has been associated with better preparedness.
Results from this study may provide some indication associated with the benefits of utilizing technology from LED color-changing lights, such as that found in the WalaLight system, in educational facilities.
