It has long been recognised that working under quality lighting relieves eyestrain and the discomfort it brings, but now the relationship between light and well-being is about to take on a whole new dimension…

Four years on from initial trials in isolation wards, a brand new lighting system that kills the most powerful of superbugs – including MRSA, E.coli and TB - is being installed Glasgow Royal Infirmary’s Intensive Care Unit in what is a world first for a trial of this kind.

The HINS-light Environmental Decontamination System has been developed by scientists at the University of Strathclyde in consultation with experts from the NHS and Glasgow Caledonian University. Their research recognised that a small range of wavelengths can neutralise bacteria both in the air and on exposed surfaces. The new technology harnesses these wavelengths and bombards bacteria, thereby acting as a constant disinfectant, making it much more effective than manual cleaning.

With technology this powerful, could there be a potential threat to patient well-being? Not according to Strathclyde researcher Dr Michelle Maclean, who says “While HINS-light is deadly to pathogens, it is harmless to patients and staff, and will allow hospitals to continuously disinfect wards and isolation rooms.”

If successful, the trial could mark a huge step in the battle against hospital-spread infection.
