Man is naturally an air animal. He breathes with the pores of the skin as well as with the lungs. However, the custom of hiding the body under dense, heavy clothing, thus excluding it from the life-giving influence of air and light, together with the habit of warm bathing, has weakened and enervated the skin of the average individual until it has lost its tonicity and is no longer capable of fulfilling its natural functions.

The compact, almost airtight layers of underwear and outer clothing made of cotton, wool, silk and leather prevent the ventilation of the skin and the escape of the morbid excretions of the body. The skin is an organ of absorption as well as of excretion; consequently the systemic poisons which are eliminated from the organism, if not removed by proper ventilation and bathing, are reabsorbed into the system just like the poisonous exhalations from the lungs are reinhaled and reabsorbed by people congregating in closed rooms or sleeping in unventilated bedrooms.

Who would think of keeping plants or animals continuously covered up, away from the air and light? We know they would wither and waste away, and die before long.

Nevertheless, civilized human beings have for ages hidden their bodies most carefully from sun and air, which are so necessary to their well-being. Is it any wonder that the human cuticle has become withered, enervated and atrophied, that it has lost the power to perform freely and efficiently its functions of elimination and absorption? Undoubtedly, this has much to do with the prevalence of disease.

In the iris of the eye the atrophied condition of the skin is indicated by a heavy, dark rim, the so-called scurf rim. It signifies that the skin has become anemic, the surface circulation sluggish and defective, and that the elimination of morbid matter and systemic poisons through the skin is handicapped and retarded. This, in turn, causes autointoxication and favors the development of all kinds of acute and chronic diseases.
