Is the interior of the human body bathed in any light, or does it function in darkness?

The eyes might let light into the skull; the skin is porous and may also allow light to pass through. There is a possibility we are light in some places dark in others; anyone know for sure?Is the interior of the human body bathed in any light, or does it function in darkness?
Normal light does not get any further than about 2 mm into the skin. If you shine a very bright light on one side of your hand, you may see a red glow through it, but that's about it. Light which hits you eye it converted to electrical impulses by the photosensitive areas of the retina, it does not travel as light throughout the body.Is the interior of the human body bathed in any light, or does it function in darkness?
Light energy would be most likely be transformed into chemical energy.





I'm thinking of vitamin D and its conversions into a valuable cell component.





Hope this helps a little on such an interesting question.

Interesting question.


Hold your hand up to the sunlight. Can you see through your skin, even a little? Do you see any of your finger bones?


Or shine a small flashlight inside your mouth, with your lips closed around it. Do you see any light glowing on the inside of your cheeks while looking in the mirror in a dark room?





Remember that babies and small children have very thin, transparent skin.


Light would be blocked by fatty tissue, but what about very thin skin tissue with very little body fat?
The only contacts of our interior body with the external environment are through the mouth and anus from where possibly any light could come inside.


But the these two openings are further joined togther by a long tube called the alimentary canal. Therefore there is no possibility of any light entering into our body.


Another possibility that may be through our nose, but that too ends blingly into lungs.


All these openings lead into passages which are coiled and crooked extensively.


In ';light'; of the above facts, our inner body just gropes in darkness!!!
i know for a fact that there is no light in our body, we know this because light would completely desrtoy the chemical balance in one's body.
no light. tissues are opaque.
