That’s not true. We’ve evolved while being irradiated by the sun for literally billions of years. Your body has mechanisms to repair damaged DNA and kill+replace cells that are too damaged. Issues arise when the damage grows fast enough for your body to keep up repairs. E.g. you get a sun burn because you don’t have an adequate tan or you hug a reactor meltdown.

Supplements are an inadequate solution for many reasons.

1. Vit D supplements barely get absorbed by the stommach. The only way to get adequate vitamin D levels with supplements is to take huge doses for like a month while testing your blood to see if levels are adequate.
2. Most available Vit D supplements take a week to be metabolized into the active form.
3. Vit D supplements can give you an overdose of Vitamin D and have severe negative health consequences.

Meanwhile half an hour of sunlight gives you healthy levels of Vit D without risk of overdose.

I’m not advocating for 1000W/m^2 UVB radiation blasting you 24/7, I’m talking about levels that are low enough that you can constantly be exposed to without a increase in risk.

And btw a lack of vitamin D causes severely bad health outcomes, even if it would cause a minor increase in skin cancer (which it doesn’t), the benefits of adequate vitamin D levels would vastly outweigh that risk.

Same with melatonin, supplements can’t replace the effect of exposure to infrared light. But at least with infrared people won’t spread misinformation about how there’s no safe levels.
