From fire and water came the spark of life of which emerged a complex biological system of what we know now as the human body. The purpose, the biological purpose of how are body was designed in order to survive the challenges of our environment is not only rudimentary, but primordial in origin. Sun exposure, temperature changes, food intake, immune strength; these our all elements that effect and challenge our bodies future level of survival. A lack of sunlight, for example, can have an effect on lowering Vitamin D levels which could result in larger health issues later. A lack of Vitamin D can also increase the risk of many types of cancer and lung diseases. This is the top reason for our need to be exposed to sunlight in order that our body receives and produces enough Vitamin D. The fact that electrons from the sun must pass through the skin to be processed in cells is example which demonstrates that ‘skin’ is a natural receiver or conduit of sunlight, in the form of electrons. These electrons are then processed within our skin to produce active levels of Vitamin D which maintain healthy processes within our body. This is another reason why we should not overlook the importance of maintaining healthy skin in relation to sun exposure. Ten minutes daily is sufficient. Sunlight also prevents many bacterial and viral infections. More importantly, sunlight strengthens our immune system by providing the platform to build our white blood cell count, and having a normal healthy level of White Blood Cells by which our body maintains a healthy immune system. The importance of maintaining our skin should not stop at our appearance, it now becomes a health issue pertinent to the very nature of our survival.
