While taking the air bath, the skin may be rubbed or brushed with a rough towel or a flesh brush in order to remove the excretions and the atrophied cuticle. The friction bath should always be followed by a spray or a cold-water rub.

At the time of the air bath, practice breathing exercises and the curative gymnastics appropriate to your condition. (See Chapters Twenty-Eight and Thirty on "Correct Breathing" and "Physical Exercise.")

If the air bath is taken at night, before retiring, the less active breathing exercises, as numbers 1, 3, 7 and 13, may be taken with good results, but all vigorous stimulating movements should be avoided.

As the plant prospers under the life-giving influence of water and light, so the cuticle of the human skin becomes alive and active under the natural stimulation of water, air and sunlight. From the foregoing paragraphs it will be seen why the air and light baths are regarded among the most important natural methods of treatment in all the great Nature Cure sanitariums of Germany.
