LRC Survey Suggests More Daytime Light Delivers Better Sleep and Mood
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is investigating the impacts of working from home or quarantining indoors due to the COVID-19 pandemic on individual daily light exposures, and how this may be affecting sleep quality and psychological health. In May 2020, the LRC invited people who had been staying home due to the pandemic to complete a short survey about their sleep, mood, and daily light exposure. A total of 708 people responded, which some interesting results.
