Geographical orientation of skin color

Are you obsessed with skin color? Many people with dark skin crave for the fairest skins. It is a meaningless, especially for those who try to use options like plastic surgery, cosmetic surgery, or other artificial means. Some people use laser therapy and cosmetic formulations that offer fairer skin. While some medications or skin care products, including face and body creams, herbal medicines, traditional medicines, sun protection products or sun blocks can be harmless, total change of skin like skin transplants can be harmful in the long run.

If we observe the habitats of various peoples, we may find a geographical orientation to the skin tone of each tribe or clan. People who had their original habitats on both sides of the equator are the darkest. When we move towards the north and south in the Torrid Zone itself (23.5 degrees north and 23.5 degrees south of the equator), we can find people with lighter shades of skin color than the people right on the tropics. Then, in the Temperate Zone (23.5 to 66.5 degrees north and south) we can find people with much lighter skin colors. For instance, people in North African countries have much lighter skin colors than the people in equatorial Africa. Just crossover the Mediterranean and watch the original inhabitants in the Southern parts of Europe. Compare it with the skin color of the Africans just on the southern coast of the Mediterranean Sea. In fact the difference is not much, provided you pick those people who inhabited these areas for a few generations. Don’t take the migrant populations on both sides.

From 66.5 degrees north and south to 90 degrees N and S (Frigid Zone), we can find the fairest skin colors. It is not that within each zone (Torrid Zone, Temperate Zone and Frigid Zone) a typical skin color is evenly distributed throughout the zone. But the color becomes lighter as we move from the equator towards the poles. The skin color transformation is gradual, fading from the dark hues to the fairest as we move from the equator to the Polar Regions.

For This observation we must exclude the people who migrated to other countries, like the whites in South Africa, and similarly located countries. The African peoples (Afro-Americans) or dark skinned Asians in the United States of America, Canada, European countries or countries in regions of milder climates are also not included for this study. We consider only those people who stayed in a region for generations. By living permanently in a particular climate, the skin color slightly changes. In the course of further generations’ evolution, skin color becomes lighter in milder climates and darker in hot and wet climates. Changes can be observed in white people becoming slightly darker by staying permanently in a hotter climate. A temporary change can be observed in what we call suntanned skins. But the skin acquires the original color when the observant moves to his/her original habitat or stays indoors.

The skin color becomes lighter when we move from the equator to the poles. It is because the sun’s rays fall directly and vertically on the equatorial regions. In the frigid zones sunrays are slant. Further, sunrays travel more to reach the frigid zones. Frigid or polar regions also have the shortest days and longest nights. So, the exposure to sunlight is the shortest for the people in these regions and heat and radiation are the least. Sunrays also have invisible rays like ultraviolet rays (UV) and infrared rays (IV) beyond the visible spectrum of sunlight. These rays can cause various disorders including skin cancer. Therefore, the dark skin is a blessing given by nature to the people who inhabit the regions where harsh direct sunrays fall throughout the year. Dark skin, it is scientifically proved, can withstand the harmful radiations of the sun, including ultraviolet rays and infrared red rays. So, dark skin is a blessing given by nature to those in the hotter regions to protect themselves from the harmful radiations of the sun.
