Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?::Can special lightbulbs end the next pandemic before it starts?
UV light kills almost all viruses because it’s ionizing EM radiation. So it also fucks humans up, xd.
An actually halfway decent idea might be adding a strong UV light inside the washing machine or dryer to kill germs. Modern eco methords with 30-40 C° just dont kill the germs effectively. You’d need to wash your clothes at last at 60C° which most clothes (especially sports wear) cant handle anymore. Or just dry them on the outside where we also have a Strong UV source aka. The sun.
I’d like to know which 12 users upvoted this so that I can block them all.
This is the best summary I could come up with:
Ultraviolet retained a small coterie of enthusiasts over the ensuing decades, focused narrowly on preventing transmission of tuberculosis — which has no reliably effective vaccine for adults — in its remaining hotbeds, like homeless shelters.
The biggest test it received, the Tuberculosis Ultraviolet Shelter Study of 1997-2004, demonstrated that “upper room” UV, in which UV-emitting lamps are placed at least 6.9 feet above the floor where they can disinfect air without harming humans, was safe.
It wasn’t — detective work from scholars including Linsey Marr, Jose-Luis Jimenez, and Katherine Randall in the middle of the pandemic determined that this conclusion was based on a misinterpretation of the Wellses’ research that had somehow persisted for decades in the medical profession.
“This is the most difficult talk I’ve had to give in my career,” Jose-Luis Jimenez, a distinguished professor of chemistry at the University of Colorado, told the audience at the first International Congress on Far-UVC Science and Technology this past June.
But 2020 was also an unusually brutal year for airborne disease: 49,783 Americans died from influenza in 2019, for instance (and none from Covid); 1 percent of that number is about 500 people, which starts to feel comparable to the air pollution cost Jimenez identifies.
Jimenez favors using UV in very high-risk locations, such as hospitals, but worries that construction companies, schools, malls, and the like will seize on the potential of far-UV as an excuse not to invest in proper ventilation and filtration, leaving us with the ugly trade-off he identifies.
The original article contains 4,104 words, the summary contains 252 words. Saved 94%. I’m a bot and I’m open source!
In Macau, they have little trash garages which are flooded with UV at night
We installed one in the kitchen cabinet trash and recycling “drawer bins,” as well as behind the stove and fridge. It smells of ozone, but there are no bugs or trash smells
You’re generating ozone in your house. You might be okay if you have a good furnace filter?
Why not inject UV as a cure for all virus infections!
This way it wont reach our eyes or skin so no problems!
The bulbs don’t last very long last time I looked into this for home use
Shadows.
I could see UV light also causing plastics to oxidize and become brittle much faster, because they might not be made for that kind of exposure. So using UV light might mean having to replace a lot of plastic things too.
Exactly, yes! Pretty much everything when left out in direct sunlight eventually fades or breaks down. There’s a reason why UV light kills germs, it damages what is touches.
can it kill Tardigrades though?
I’m pretty sure nothing can kill tardigrades.
Because my curtains are closed

Not necessarily agreeing with the article posted, but for all the people who clearly didn’t read the article:
www.nature.com/articles/s41598-022-08462-z
That’s just one paper I found searching for far-UV. Seems to be many more.
Again not saying it’s 100 % safe or anything, but it looks promising.
