When you think of disinfecting a space, what comes to mind? Wipes? Gels? Sprays? Maybe air purifiers or effective HVAC systems? All of these are great defenses against viruses and bacteria, but one thing has been missing from the toolkit despite our knowing about it for over a century: light.
Ultraviolet light is an incredibly powerful disinfectant. Study after study has proven that it can obliterate viruses and bacteria, and yet it’s not often thought about as a defense against germs. In fact, when most people think of UV, they think of the harmful rays from the sun that cause cancer — not the PR you want when advertising, obviously. Luckily, a few years after the pandemic lockdowns, researchers have found a type of UV that isn’t strong enough to penetrate human skin but still effectively stops the germs. Could it be our next defense? Check out the video above to learn more.

Interesting.
This knowledge has indeed been around for a long time.
The EU’s Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) has a favourable opinion but is being cautious because of the lack of studies on Humans. European (including UK) tend to be very cautious particularly with the history of asbestos and thalidomide.
And it would not take much for the Conspiracy Junkies to claim its use would affect our brains and make us automatons of a government. Natural feeding ground for the MAGA crew,(Remember the fluoride hoo-hahs).

Hello Roger. Yes there were claims during the early days of covid that light could be used to disinfect a room or building quickly, also that big air filters with electric and UV lights in them could clean rooms and buildings but no one could prove they worked. In fact some were found to be outright scams. Yet I know as a kid I use to see the barbers keep their tools in a blue light small device. Hugs. Scottie

Oh yes, I’d forgotten about those.
They used to send my younger mind’s Sci-Fi imaginings into all sorts of places (I used to imagine those ominous hums so beloved on TV and Film Sci-Fi sound effects.)

Oh Roger. I also loved the older Sci-fi ideas, because when I gained the ability to see them they may have been old, but eye-popping to me. And yes, the old sound effects seem so much more real to me than modern movies. Hugs. Scottie

They had a style all of their own.
The 1953 ‘War of the Worlds’ film for instance.
