Is Wearing White Or Black Clothing Better For Sun Protection
Doesn't matter.: Ultraviolet light passes through (or is blocked by) clothing at the same rate, no matter what color it is. However, black clothing will absorb a lot of heat, while white clothing will reflect it. So if it's hot out, you'll be more comfortable in a white outfit. Read more

SPF: There's a perception that people with darker skin don't have to worry about skin cancer, but that's not true. Minorities do get skin cancer, and because of this false perception most cases aren't diagnosed until they are more advanced and difficult to treat. Use an spf of 30.

Yes: Wearing protective clothing is much more effective than spf. Also, frequent reapplication of sunscreen is very helpful. None of the 'waterproof" sunscreens are really waterproof, and will rinse off while in pools or the ocean. Read more
Sunscreens: The new ratings do not include a term, sunblock, any more. Sunscreens can protect against both ultraviolet a and ultraviolet b cellular damage to your skin. Some of the older ultraviolet a agents were found not to be stable in the sun! Newer generation sunscreens have photostable uva blockers.

SPF: Spf stands for sun protection factor. The number is determined experimentally indoors by exposing human subjects to a light spectrum meant to mimic noontime sun. Some subjects wear sunscreen and others do not. The amount of light that induces redness in sunscreen-protected skin, divided by the amount of light that induces redness in unprotected skin is the spf. It is mainly a measure of uvb protec.

SPF measures UVB: Spf is the most familiar method of measuring sunscreen effectiveness, but it doesn't tell the whole story and new labeling regulations will be applied soon. Ultraviolet light from sunshine is divided into "a" and "b" wavelenths, with uvb causing burning and uva more linked to aging. And spf of 15 means that it takes 15 times longer to cause redness of the skin with uvb exposure. Read moreSee 2 more doctor answers
Depends: Some t-shirts are made to block uva and uvb radiation. These are usually marketed to boaters, fisherman, etc. Normal clothing blocks most uvb but not uva. Sunblocks can block both or only uvb as well. You need to read the specific coverage of the sunblock. Read moreSee 1 more doctor answer
Short/long term dmg: Your question concentrates on the short term risk of sun exposure, which is that messy burn so many get. It may be comforting that he doesn't burn easily. However, the long term effects of solar radiation on the skin include such things as a lifetime risk of melanoma or other cancers. Life is a marathon, not a sprint.

No: Cancer develops and grows based on changes in the oncogene components within the cell. Mutations in genes such as p53 are induce by viruses or carcinogens. As an example, the LTR of the MMTV virus enters the Wnt-1 gene to induce overproduction of B-catenin causing aggressive behavior. This does not occur by type of cloths worn in sun. Latter causes increased sweating and not Ca. Read more
