A man once wrote that, “by wearing magnetic appliances, ozone was developed in the blood.” Whether he knew what ozone was, or what condition the blood was in when ozone was in it, is not proven. If, however, it is possible to get a condition in which you feel that there is “ozone in the blood,” it is after one of these quick, cold, tonic, invigorating baths. My experience in prescribing it has proven that it is not debilitating, even when taken twice daily. Too many warm baths may, in time, reduce the physical standard. But simply wetting the surface, with hand, sponge or towel in cold water, or, what some prefer, dashing cold water quickly over the body, is a decided tonic. A little courage and perseverance is required to form the habit--once formed, few relinquish it. If no reaction follows, and the person remains cold, it should not be persevered in. THE SITZ-BATH is one of the most desirable baths for the pregnant woman. A tin tub made especially for this bath (procured of dealers in tinware), requiring but little water, ought to be in every household. If unable to procure one, a small-sized wash-tub can be used, raising one side on a block of wood. Tepid water is the most beneficial, unless for the relief of pain or acute inflammation, when hot water should be used. Commence taking it with the temperature at 90° Fahrenheit, and gradually reduce it, until, during the last months, it is as low as 60°. Remain in it from three to eight minutes, then have towel and hand friction, followed by rest in the reclining position, and sleep if possible. If it causes a rush of blood to the head, remain in for a less time, and put a wet napkin around the neck. From ten to twelve o’clock in the morning is the best time to take this bath. If one has not time to rest at this hour, it can be taken just before retiring. Without the rest, half the value is lost. This bath is a tonic, sedative, alterative, laxative, diuretic, anti-spasmodic, anti-periodic, anti-phlogistic, etc.; indeed it will do almost anything desired to be done for the pregnant woman. It restores nervous equilibrium, it removes obstructions from the surface, is invaluable for portal congestion, and for inflammation of any of the abdominal or pelvic viscera. Nothing is better for insomnia, facial neuralgia, nausea, biliousness, constipation, hemorrhoids, cramps, varicose veins, weariness, headache, nervousness, etc., etc. A woman has omitted the most effectual remedial agent for pathological symptoms, if she has not tried this bath; and not once only, but has taken it every day, or twice a day for at least a month. She may have taken any amount of remedies, may have used outside appliances, but if she has not had this tepid sitz-bath, she has omitted the _very best_ and surest means of relief. It cannot do harm, and it _can do great good_.
