However, correlation is not causation, so it is not clear if the mental disorders cause circadian disruption, if circadian disruption causes mental disorders or both in a positive feedback loop.

The Journal of Post-Acute and Long-Term Care Medicine (JAMDA) recently published a research study showing long-term care facility falls were reduced 43% by changing light spectrum and intensity throughout the day for residents.

The U.S. Department of Energy has released two reports which characterize the current state and viability of commercial ultraviolet (UV) LED products.

Randy Reid and Katie Smith recently published an article on LinkedIn, about UL’s latest moves into circadian lighting.

Signify’s NatureConnect natural lighting system mimics the natural patterns of daylight indoors to create a unique daylight experience. The intensity and shadows change throughout the day. It creates interesting lighting scenes designed to reconnect people with daylight cycles, and bring the outdoors in.

In a newly published study, researchers from Binghamton University’s Thomas J. Watson College of Engineering and Applied Science answer many of the questions about UV disinfection of the virus that causes COVID-19, and lay the foundation for health standards about what offers true disinfection.
