Light absorption and human skin.

Post by QuestionGuy » Mon Nov 09, 2009 10:31 pm

How do different colors affect the absorption of light into the skin?

More specifically, what would be the potential affects on human skin exposed for a prolonged period to individual colors (Red, blue, green etc.)?

Hypothetically if I rigged a couple of lights and put blue translucent sheets over the lights and exposed my body to it for 3-6 hours a day, what would be the effect (if any?) on my body in the future days/weeks/months...?

in this way, you should filter out the UV, so basically any?

BTW does human has some photoreceptors for blue and/or red light?

Cis or trans? That's what matters.

@jackbean
yes, the opsins in your eyes

@questionguy
if you somehow manage to filter out the uv, nothing will happen. if you don't filter out the uv, you will get a tan.

:lol: yeah :-D I meant something like in the skin or something. There must be something regulating circadian and melatonin release, not?
