Because we have skin and eyeballs?
Doesn’t explain why we don’t use them to sanitize rooms while we’re not in them.
What does explain it is that UV also damages stuff too. You use it to sanitize your living room, and soon the fabric on your couches will start losing their color. The paint on your walls will start flaking off. The plastic frames of the frames on the wall will start crumbling away or turning sticky. Nobody wants that in their house.
UV is used to sanitize stuff when people aren’t around but yeah, it does damage a lot of materials so that’s a pretty limiting factor. I’ve seen them used inside air circulators to kill bacteria for over a decade too (usually in hospitals and restaurant kitchens).
I have a UV lamp from when I was making sure the room was relatively sterile for our newborn.
So here’s my say:
- The room rapidly stinks of ozone. Ozone is a free radical that fucks up everything, including your lungs. We didn’t enter the room until about half an hour after the UV was off (Ozone recombines pretty quickly).
- UV lamps are frequently used to sterilise hospital rooms because people are usually immunocompromised. Our newborn was fine, but it may have helped.
- COVID turns up in the comments: you cannot emit UV everywhere anytime without, again I quote, fucking people’s lungs up. And COVID was pretty good at spreading anywhere and everywhere, so haha, nope.
- Those fun UV lamps that make stuff glow in the dark? Pretty damn close to visible colour violet, and low intensity (we use them in the dark, no?). This UV lamp for sterilisation? Look at it for a couple of seconds and you are already burning a hole in your retina.
If this also affects other bacteria and germs, wouldn’t that mean people would not build up immunity to anything around them. It’s reasonable for places like airports, hotels, and public spaces and subways but not “everywhere”
Possibly but it also might cause it to go into overdrive. The immune systems ultimate goal is to find things that are not you that are inside of you and remove them. An immune system with no interaction with the outside environment could be vulnerable to very mild infections or it could start to recognize parts of itself as foreign and attack itself, otherwise known as autoimmune disease. It’s a complicated system that we don’t fully understand, although we have a pretty good understanding.
Those NFT losers had a similar idea, and while it may have burned their eyes and skin it’s probably the closest they’ve ever come to a shower.
Because doing that is stupid. Bullets can kill viruses too if they hit them dead on, why don’t we have them everywhere too? Just in case.
This reply hurts my brain …
A lot of people missed the point but w/e
More like “Bullets can kill almost all the terrorists in a room. Why aren’t they everywhere?”
