We recall that the formation of life in the primordial seas began with the building of proteins and the construction of cells. These cells formed tubes. Nutrients entered the tubes and toxic waste products left the tubes. By simply contracting and relaxing the tubes forced the passage of the nutrients and the waste products in and out. This simple mechanism has not changed in the millions of years that have passed.
We can see then that the circulation of blood through our body is a more complex manifestation of the original process. When we heat the body, the blood flows more quickly since the heart is pumping faster. In addition, the arteries dilate and a larger amount of blood is flowing.
The size of the veins and arteries diminishes greatly as they approach the cells. When these arteries and veins reach the cells their walls are composed of only one cell and fluids move in and out freely.
Fluids that leave the cells need more than veins to return to the heart. A system of tubes similar to veins has evolved. These tubes are called lymphatic vessels and they are linked to the defense system of the body. These areas of defense are known as lymph nodes and they are populated with cells that attack invading micro-organisms.
When we heat the body, we not only increase the flow of nutrients to the cells and increase the flow of toxic waste products away from the cells we also increase the exposure of invading micro-organisms to the immune system of the body. This is a three pronged advantage which promotes the health of the body.
An additional advantage lies in the fact that abnormal cells, such as cancer cells, and invading viruses and bacteria, are faced with an environment that is hostile. Some medical scientists have used intense heat in an effort to combat cancer. Their results, as yet, are undetermined. Heat has also been used in an effort to combat serious infections.
The results that we have described only describe the effects of heat on the large circulation, the circulation that involves the heart, the arteries and the veins and lymphatic vessels–there is another circulation that most scientists do not mention. That circulation is the “Micro-Circulation.”
HEAT AND THE MICRO-CIRCULATION
Between the cells of our body are microscopic SEAS filled with a liquid that has filtered out of the cells and which contain the many toxic byproducts of metabolism. In that same sea are the nutrients that the cells need in order to stay alive. In those seas are millions of long fibers which maintain the structural resiliency of the cellular tissue.
