Of the five senses sight, sound, smell, taste and touch, which provides the most information to the brain?

For obvious reasons, I thought it is sight, but it turns out that there is a huge area reserved in the brain for the sense of touch. Vision, also occupies a large portion of the brain, by the way. 

Having watched "The biology of belief" by Bruce Lipton, I knew that our skin is the most intelligent part of our body and from its 3 layers of ectoderm, mesoderm and endoderm, as a single cell, all our skin, nervous system, skeleton, circulatory system, brain, eyes, heart, liver, kidney etc are manufactured. Every nutrient necessary for the development of the cell is allowed inside the cell and foreign agents are kept outside the cell by the intelligence of cell membrane (membrain, as one doctor puts it).

So what about the skin of the grown up adult? Does it provide any kind of nutrition? I think it provides the wholesome nutrition from the Sun. With a huge surface area, our skin has been converting solar energy into vitamin D, a critical ingredient in our health, for centuries. (Watch the video below- What if you stopped going outside?)

Cells containing the black melanin pigment line the back of the photoreceptors, rods and cones, in the retina absorbing all the light and preventing scattering in the eye. The outer segments of rods and cones are destroyed (bleaching) when exposed to light and regenerated at end of day for cones and at end of night for rods. Melanin helps to chemically restore the rods and cones, every day and night.

In our skin, melanin is believed to be the natural sunscreen and is the main UV absorbent, antioxidant, scavenger of radicals and the primary determinant of vitamin D synthesis. Yes, we use UV B and cholesterol to synthesize vitamin D. Our cells can also repair certain type of DNA damage. Wait a minute, did we evolve from UV B light?  http://www.eurekalert.org/pub_releases/2003-05/bc-but052703.php

If tiny amounts of melanin can absorb light and aid in photoreceptor regeneration, what could be the purpose of the huge amounts of melanin in our skin? To cause skin cancers?

Now let us look at the infrared radiation. Most of IR from the sun's electromagnetic radiation is absorbed by the atmosphere. But as more sunlight radiation is absorbed by earth, it emits IR radiation as heat (greenhouse effect).  http://www.acs.org/content/acs/en/climatescience/climatesciencenarratives/what-is-the-greenhouse-effect.html

So for eons, more light is always associated with more heat, direct and indirect. This heat variation through seasons is also mediated by our skin for maintaining our body temperature. Now, with air conditioning, more light could mean cold weather! 

Both these electromagnetic radiation bands, UV and IR, have been termed as the "invisible" light and are on either side of the visible light spectrum beyond the violet and red. Could it be, that our skin, was designed to deliver the goodness of "invisible" light and our eyes, designed to deliver the goodness of visible light to deep layers within our body through various biological transformations? 

If solar radiation provides us with a wholesome food of IR, visible and UV light, we have been consuming only the refined food, the visible light. It is like the wholesome food being ripped off their original nutrient content and fibre for producing commercial refined foods.

Even in buildings with daylight harvesting techniques, IR and UV radiations are almost eliminated with glazing and only visible light is allowed inside the buildings. And in most buildings artificial light provides the visible light. 

Instead of IR and UV radiations, our skin is exposed to an overdose(limited in natural settings) of microwaves, nowadays, from our electronic gadgets, towers and satellites. Are we moving from the refined food to the artificial junk food? Time will tell. 

Can we design buildings which restores the natural setting of higher visible light mixed with the optimum doses of "invisible" light? Even though it is difficult to escape the commercial compulsions in our industrialized world, still architects are slowly breaking the barriers between humans and nature.

What do you think? Are you aware of any designs which connects with nature? Please share.

I aim to spread awareness on the subject of Healthy Lighting designs to facilitate co-creation of healthy lighting at home, work and other social spaces. My posts can be accessed at Archinect  and Linkedin Group. I also have a self published book "Healthy Lighting of your Homes" at Amazon.
