A great many cannot see why it is they do not take cold when exposed to cold winds and rain. The fact is, and ought to be more generally understood, that nearly every cold is contracted indoors, and is not directly due to the cold outside, but to the heat inside. A man will go to bed at night feeling as well as usual, and get up in the morning with a royal cold. He goes peeking around in search of cracks and keyholes and tiny drafts. Weather-strips are procured, and the house made as tight as a fruit can. In a few days more the whole family has colds.

Let a man go home, tired or exhausted, eat a full supper of starchy and vegetable food, occupy his mind intently for a while, go to bed in a warm, close room, and if he doesn't have a cold in the morning it will be a wonder. A drink of whisky or a glass or two of beer before supper will facilitate matters very much.

People swallow more colds down their throats than they inhale or receive from contact with the air, no matter how cold or chilly it may be. Plain, light suppers are good to go to bed on, and are far more conducive to refreshing sleep than a glass of beer or a dose of chloral. In the estimation of a great many this statement is rank heresy, but in the light of science, common sense and experience, it is gospel truth.

Pure air is strictly essential to maintain perfect health. If a person is accustomed to sleeping with the windows open there is but little danger of taking cold winter or summer. Persons who shut up the windows to keep out the "night air," make a mistake, for at night the only air we breath is "night air," and we need good air while asleep as much or even more than at any other time of day. Ventilation can be accomplished by simply opening the window an inch at the bottom and also at the top, thus letting the pure air in, the bad air going outward at the top. Close, foul air poisons the blood, brings on disease which often results in death; this poisoning of the blood is only prevented by pure air, which enters the lungs, becomes charged with waste particles, then thrown out, and which are poisonous if taken back again. It is estimated that a grown person corrupts one gallon of pure air every minute, or twenty-five barrels full in a single night, in breathing alone.
