Science

I have a UV lamp from when I was making sure the room was relatively sterile for our newborn.

So here's my say:

1. 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).
2. UV lamps are frequently used to sterilise hospital rooms because people are usually immunocompromised. Our newborn was fine, but it may have helped.
3. 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.
4. 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.
