I don't know; I am not a doctor. I'm sure we all get some degree of UV light inside our noses and mouths, probably not inside our lungs. But it's worth researching, don't you think?

UV light can penetrate clothing and skin, that’s why people can get sunburned if exposed to too much at a time, and how much they get depends on their melanin or lack thereof. Skin is translucent.
