Your tan isn’t doing anything. Radiation is still penetrating deep into your skin and damaging DNA, leading to potentially cancerous mutations.

- colechristensen 4y agoIf this was true we wouldn't see human skin tone mapping pretty directly to ancestral UV exposure.
- kgc 4y agoIt does.
- elevaet 4y agoThat was their point
- xwdv 4y agoNo, it’s my point. We see skin tones mapped because all the lighter skin people died out faster than they could reproduce due to UV radiation killing them off sooner in life. Melanin rich individuals are more resilient, but that is not purely because of their skin and tanning won’t give you their power.
- colechristensen 4y agoThis is some strange magical thinking. "Your tan isn’t doing anything." you say, despite clear evidence that melanin is associated with ancestral UV exposure and how your body develops a tan in response to UV exposure. Now you're suggesting a separate unnamed method of resilience associated with darker skinned people. I guess go ahead and fear the sun, you do you.
- xwdv 4y agoIt’s very magical to think a tan is more powerful than the radiation of a burning star.
- xorfish 4y agoIs there solid evidence, not just theorizing, for this? Our bodies can deal with damaged DNA. Proving that low rates of DNA damage increase cancer risk proportionaly to the risk asociated with high rates of damage seems nearly impossible. So I don't understand the absolute certanty with which it gets proclaimed as fact.
