A new study from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute found that office workers who receive a robust dose of circadian-effective light in the morning, from electric lighting or daylight, experience better sleep and lower levels of depression and stress, than those who spend their mornings in dim or low light levels. [...]
