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?

IIRC, they have UV sterilizers for central HVAC systems. So while it may not sterilize surfaces, it will kill all airborne pathogens.

A bit of the old Ultraviolence, eh?

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.

Not necessarily agreeing with the article posted, but for all the people who clearly didn't read the article:

https://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.

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

I always thought these were pretty cool. I'm not sure how HEV compares to UV though, or if it even works

The bulbs don't last very long last time I looked into this for home use

UV light kills almost all viruses because it's ionizing EM radiation. So it also fucks humans up, xd. I mean just stay on sunlight naked for a day. Your body will be so happy. All the mutations from ionizing radiation would be great.

But yeah we life in a society where ppl is scared of Radiofrequency EM waves (non-ionizing), "dangerous cell phone towers, wifi dangerous". That same people recomends staying long periods of time with direct sunlight contact without protection (yeah we need protection because sunlight spectrum has UV and higher freq ionizing radiation).

Sunlight healthy/radio waves dangerous, that is the most stupid statement ever.

Sunlight is beneficial in small dosis because of how we syntetise vitamins (as little as i know). But remeber if you are scared of microwaves, remeber that sunlight has much more higher freq(higher energy) waves.

That’s how you get UV resistant strains of all kinds of microbes

The issue with stuff that kills everything is that... Well it kills everything.

[–] Buffalox@lemmy.world 9 points 9 months ago (1 children)

At this point, it’s clear that in small-scale settings, far-UV can kill the vast majority of pathogens present, which in turn would vastly reduce the risk of respiratory disease spread. It seems safe for human skin, and likely safe for human eyes, too.

Luckily we are more thick skinned than a bacteria, who would have thought?
