I've lived in the mountains my entire life, this is what I know....... In the mountains there is less oxegen. The atmosphere seems to be thinner, therefore we actually burn easier. The higher the altitude the less oxegen and the thinner the atmosphere. The occurence of less oxegen in the air is what causes altitude sickness.
The disadvantage is that if it is over concentrated on your skin, it can get burned.

UV stands for "ultra violet" and consists of light frequencies higher in value than violet light.

Ultra violet light is not visible!
No. "Ultra"-violet is "past"-violet ... higher frequency/shorter wavelengththan anything to which your eyes are able to respond.
Our eyes can't see ultraviolet light, so it has no color. The highest frequency our eyes can see is violet, and ultraviolet is above that frequency. The name ultraviolet just means "above violet."
the length of an ultra violet wave is about 0.4 nanometers
