During the warm weather, the hot bath is a great luxury. For the moment it makes you warm, but the secondary effect, or reaction, which will continue for a long time, leaves you in a cool, comfortable state. Foot baths afford a happy illustration of this Homoeopathic law, "_Similia Similibus Curantur_,"--"_like are cured by like_." You are troubled with cold feet. Dip the bottoms of your feet in cold water. Let the water be half an inch deep. Hold the feet there four or five minutes, and then give them a good rubbing. Perhaps stand on the carpet with your naked feet, and twist from side to side, until your feet are burning. Not only will your feet remain warm all night, but after practicing this two or three weeks, unless your digestion is _very_ weak, your feet will become warm as a habit. On the contrary, if you are troubled with burning feet, a frequent hot foot bath will cure you. But in every case the employment of hot foot baths will give tendency to cold in the head. But you say again that you like cold baths well enough in warm weather; but if you use the cold bath in the winter, it makes you cold and shivery, it gives you headache and depresses you. Ah, I see you haven't taken the bath in the right way. If you take it in the way I suggest, no such effects will follow. Apply soap to every part of your skin rapidly with your bathing mittens. That is the most important part of the bath. Now put on just as much or just as little water as your comfort may suggest. If you can bear a good deal, you may put it on; but if you are sensitive to the cold, manage in the way I have suggested,--put on the soap, follow with a damp mitten, and do it all just as rapidly as your hands can move, so that from the time you take off your night dress, until the soap has been applied to every part of the body, and followed by the damp mitten and dry towels, will not be more than one to two minutes. If this is done in your bedroom, instead of a cold bath-room, you will hardly be chilled or depressed by it. If you are so exceedingly sensitive that even this momentary exposure with a moist skin produces an unpleasant chilliness, then follow the soap bath by the most vigorous use of a pair of hair gloves. HAIR GLOVES OR MITTENS. For three thousand years, hair mittens have been in use. Hippocrates rubbed himself with a pair.
