Ushio Inc. and a research group led by Dr. Ryosuke Kuroda, Chairman and Professor of the Department of Orthopaedic Surgery, Kobe University Graduate School of Medicine, have completed a research study that shows that irradiation of filtered 222nm UV-C light on human skin reduces bacterial counts while causing no injury. This is the first study on the safety of 222nm far UV-C light conducted on humans.

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.

Risks and Rewards of Germicidal UV
On its website, the International Ultraviolet Association makes a case that UV disinfection can play a role in a multibarrier approach to reducing transmission of SARS-CoV-2, the virus causing COVID-19. This may lead to increased applications for GUV in buildings, but there are risks. My latest contribution to ELECTRICAL CONTRACTOR spells it out.
