It's Vitamin D. There was this whole thing during the COVID pandemic about how the FDA/CDC were SUSPICIOUSLY QUIET about how impactful Vitamin D levels were on COVID outcomes or something and how that's how you know that... something something sinister ulterior motives.

So like the idea was that everybody going outside and getting some sun was actually the best thing for public health, but THEY were telling you to languish inside under lockdowns, because clearly they didn't want you to be healthy.

To be fair, non-mineral sunscreens do fuck with your hormones a bit. Still better then skin cancer though.

There was a finding a few years ago that while preventing skin cancer, sunscreen was also causing people in some places to get less vitamin d which was increasing instances of colon cancer. The solution isn't banning sunscreen, it's making sure people get some small amount of sun or supplements vitamin d.

Being from Oz I never really considered issues with vitamin d until I moved to the UK for a few years and discovered that limited vitamin d is a real problem in winter. Im not sure on the deficiency you need for colon cancer but a few weeks of little to no Sun really messes with your head and body.

It’s quite likely a belief that sunscreen lotion is a bad thing that harms people.

I mean, it halfway is:

• "Sunscreen" -- stuff with a decently high SPF rating -- is a good thing that prevents cancer.

• "Suntan lotion" -- usually glorified coconut oil with fuck-all SPF rating -- is a bad thing that harms people.

• "Sunscreen lotion" -- a confused amalgamation of the previous terms -- is not a thing and only misleads people by conflating good things with harmful ones.
