Question: how does sunscreen affect these outcome ? I have been in a UV-high indexed area for over 2hrs a day under sun and wondered if applying sunscreen everyday as I have to exposed parts such as arms and legs have negative consequences since all of them have benzene. Now this seems to be another reason for not doing so?

Not directly answering your question but related: "early sunscreen formulations were disastrous, shielding users from the UVB rays that cause sunburn but not the UVA rays that cause skin cancer. Even today, SPF ratings refer only to UVB rays, so many users may be absorbing far more UVA radiation than they realize." https://www.outsideonline.com/health/wellness/sunscreen-sun-...

Implying that a primary causal factor for globally-declining birth rates could be... increased adoption of sunscreen, leading to decreases in libido? (I'm only half-joking; the countries that are most obsessed with keeping skin white — and so are likely the highest sunscreen users — are also the countries with the lowest birth rates.)

There are a whole host of benefits associated with sun exposure that are reduced by wearing sunscreen. “Avoidance of sun exposure is a risk factor of a similar magnitude as smoking, in terms of life expectancy.” https://www.outsideonline.com/health/wellness/sunscreen-sun-...

I don't get how reduced UV exposure is supposed to be more attributable to sunscreens than to office labors. Most industrial materials block roughly 100% of UV rays, except viewing windows which allows as much as 1%. Therefore, just staying in any modern building alone cuts down UV exposure by 99% at very least. There is absolutely no way some translucent face painting does that.
