The underlying basis of Natural Hygiene is that the body is self-cleansing, self-healing, and self-maintaining.

Natural Hygiene is based on the idea that all the healing power of the universe is within the human body; that nature is always correct and cannot be improved upon. Therefore, nature does not seek to thwart any of its own operations. We experience problems of ill health (i.e., excess weight, pain, stress) only when we break the natural laws of life.

The intelligence inherent in our bodies is so vast that it is positively staggering. The human heart beats about one hundred thousand times every twenty-four hours. Consider the fact that the heart and its pumping system, which scientists have attempted to duplicate without success, pump six quarts of blood through over ninety-six thousand miles of blood vessels. This is an equivalent of sixty-three hundred gallons being pumped per day. That is almost one hundred fifteen million gallons in only fifty years. The six quarts of blood are made up of over twenty-four trillion cells that make three to five thousand trips throughout the body every day. Seven million new blood cells are produced every second! This pumping system has the capability of working nonstop for decades without skipping a beat. And this is only the circulatory system!

Consider the heat this machine must generate in accomplishing these functions, yet realize that it maintains a constant temperature of around 98.6 degrees! The biggest organ of the body, the skin, is made up of over four million pores that are constantly acting as the cooling system for this machine. The digestive and metabolic systems have the remarkable ability to transform the food we eat into healthy blood, bone, and cell structure.

Perfect balance is always maintained, and if it were off by only a small fraction, the balance would be destroyed. The lungs succeed in supplying the blood with the oxygen it needs. A complex skeletal system furnishes a supporting framework to allow the body to stand upright and walk. The skeletal system works in harmony with an amazing muscular system that allows locomotion.
This machine can astonishingly reproduce itself! The force and wisdom necessary to turn a fertilized ovum into a fully grown man or
woman are beyond our comprehension. The five senses alone can stun the intellect. The list of activities performed by your body on a regular
basis could fill a book. At the helm of this pinnacle of perfection is the brain, overseeing all these miraculous activities, making sure everything is working with a precision that would make the work of a master watchmaker look clumsy. The brain consists of more than twenty-five billion cells that are the most highly developed of any known.

Looking at an individual cell, you will be even more impressed. A single cell cannot be seen without a microscope, yet what goes on within
a cell is astounding. The wisdom of a single cell is said to exceed all the accumulated knowledge of the human race to date. Even the smallest
cell in your body is about one billion times the size of its smallest component! The cell is the site of more chemical reactions than all the chemical factories in the world combined. There are thousands of components in a cell: chromosomes, genes, DNA, organelles, mitochondria, enzymes, hormones, amino acids, and thousands of various chemicals and compounds too numerous to mention. And no one on this earth can explain what makes an individual cell operate. All the thousands of different functions can be categorized, but the force behind these functions is beyond our comprehension. In other words, the innate intelligence of the body is infinitely more sophisticated than our thinking minds. And to think there are over seventy-five trillion (75,000,000,000,000) of these astounding cells working with pinpoint perfection for some sixty, seventy, eighty years, or more!

Inside each cell is a nucleus that contains chromosomes that contain genes. And inside genes is the stuff of life: DNA. DNA is what determines what color your eyes are, or what fragrance a flower will have, or the iridescence of a bird’s feathers. If you took all the DNA from all the genes of all your seventy-five trillion cells, it would fit into a box the size of an ice cube. Yet if all this DNA were unwound and joined together, the string would stretch from the earth to the sun and back more than four hundred times! That’s almost eighty billion miles!

Your body is performing quadrillions of processes twenty-four hours a day! Not millions or billions or even trillions, but quadrillions!
And not haphazardly, but with pinpoint perfection, carrying on all the metabolic and life-sustaining processes of your existence. When we view the vastness of the human body’s faculties and processes, we must stand in awe of the enormous intelligence displayed.

Considering these facts, is it at all conceivable that this truly magnificent machine would be left without the mechanism to achieve a proper
body weight? No! It is inconceivable. Mechanisms for the body’s self preservation are built in at birth. The same way a plant will reach
for the light source from wherever it is located in a room, so your body will forever strive for perfection. As an automatic biological process of
existence, just like breathing and blinking your eyes, the human body ceaselessly strives to be fit. The secret is to learn how to facilitate the
process rather than thwart it. Every way we interact with our environment affects our well-being, but in no other area of life are our biological
needs violated more flagrantly than in our diets.
