Benefits of Brightness (06-09-20)

Researchers at the Lighting Research Center confirm the value of spending time in brightly lit spaces.  They share that “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. . . .  Compared to people with ‘somewhat dim’ to ‘very dim’ indoor lighting, people with ‘somewhat bright’ to ‘very bright’ lighting, including having windows without (or with open) curtains or shades, or having several lights turned on, reported:  

  • Fewer sleep disturbances
  • Less anxiety and depression
  • Feeling less tired or less irritable  
  • Feeling generally happier and more positive
  • Less sleep-related impairment.”
