CHAPTER II.
CLEANLINESS.—BATHING.
One of the first things to remember is the need of keeping your bodies clean. Of course you wash your hands and face as soon as you rise in the morning, and if necessary through the day, but that is not enough.
The skin is composed of two layers, the outer or scarf skin and the inner or true skin. The outer is continually wearing out and falls from the body in fine scales. The skin is pierced by thousands upon thousands of pores, or tiny openings, through which a large part of the waste of the body passes. If these pores are allowed to become clogged by want of cleanliness, the waste matter enters the blood and may cause disease and death.
The way to keep the pores open is by bathing or cleanliness. When the weather is cold, you should bathe at least once a week at home. The water should be moderately cold. After bathing, rub yourself from head to foot with a coarse towel until the skin becomes warm and red. Then dress quickly and do not go out-of-doors for half an hour.
During summer it is well to bathe every day. Salt water is better than fresh. Boys are fond of bathing and are inclined to spend too much time in the water.
