Chapter 39—The Importance of Cleanliness
      
      
        In order to have good health, we must have good blood; for the
      
      
        blood is the current of life. It repairs waste and nourishes the body.
      
      
        When supplied with the proper food elements and when cleansed and
      
      
        vitalized by contact with pure air, it carries life and vigor to every part
      
      
        of the system. The more perfect the circulation, the better will this
      
      
        work be accomplished
      
      
      
      
        The external application of water is one of the easiest and most
      
      
        satisfactory ways of regulating the circulation of the blood. A cold or
      
      
        cool bath is an excellent tonic. Warm baths open the pores and thus aid
      
      
        in the elimination of impurities. Both warm and neutral baths soothe
      
      
        the nerves and equalize the circulation.
      
      
        Exercise quickens and equalizes the circulation of the blood, but
      
      
        in idleness the blood does not circulate freely, and the changes in it, so
      
      
        necessary to life and health, do not take place. The skin, too, becomes
      
      
        inactive. Impurities are not expelled as they would be if the circulation
      
      
        had been quickened by vigorous exercise, the skin kept in a healthy
      
      
        condition, and the lungs fed with plenty of pure, fresh air
      
      
      
      
        The lungs should be allowed the greatest freedom possible. Their
      
      
        capacity is developed by free action; it diminishes if they are cramped
      
      
        and compressed. Hence the ill effects of the practice so common,
      
      
        especially in sedentary pursuits, of stooping at one’s work. In this
      
      
        position it is impossible to breathe deeply. Superficial breathing soon
      
      
        becomes a habit, and the lungs lose their power to expand.
      
      
        Thus an insufficient supply of oxygen is received. The blood moves
      
      
        sluggishly. The waste, poisonous matter, which should be thrown off
      
      
        in the exhalations from the lungs, is retained, and the blood becomes
      
      
        impure. Not only the lungs, but the stomach, liver, and brain are
      
      
        affected. The skin becomes sallow, digestion is retarded; the heart
      
      
        is depressed; the brain is clouded; the thoughts are confused; gloom
