This is a clever idea. Unfortunately, UV exposure is cumulative. So your skin is still getting damaged by the UV rays even if you're not getting burnt.

- littlexsparkee 3mo agoThere are temporary as well as permanent effects and the repair mechanism can be overwhelmed: photoaging, age spots, mutations.
- TurdF3rguson 3mo agoRight but there are common precautionary rule-of-thumb heuristics which lead normal people to believe that every sun exposure brings them a little closer to death. That's exaggerated. Or at least, the claims are widely contested.
- chiply314 3mo agoLets be honest here, every additional sun exposre means you lived longer which directly leads you closer to death sooooo ;P
- TurdF3rguson 3mo agoThat part really is cumulative
- smallpipe 3mo agoSo how many Joules can you safely sustain in say, a month, or a lifetime ?
- giwook 3mo agoI don't think it's really helpful (nor possible) to get into this level of specificity. Generally, just apply sunscreen and limit prolonged sun exposure when possible (particularly when UV index is high). Avoiding sunburns (i.e. prolonged sun exposure, particularly when skin is unprotected) is probably the main thing to focus on as I believe studies have shown there is a high correlation between getting burnt and developing skin cancer.
