UV-A, -B, and -C are bad in different ways. Sunburns skew towards UV-A, while cancer and aging tends to be from UV-B and -C. Vitamin D synthesis results from UV-B exposure.
- borski 3y agoSure, but as discussed elsewhere in this thread, the studies (at present, which doesn’t mean we won’t learn more in the future) do not support the assertion that sunblock prevents Vitamin D synthesis in any meaningful way, despite what a random blog post might tell you.
- sacnoradhq 3y agoAmen. :) You're preaching to the choir. Health and wellness blogs generally service the theater of the placebo and hivemind ignorance bordering on mysticism.
