Baths.-- The most ordinary forms of baths used may be classified under sponge-, shower-, sitz-, and tub-baths. The sponge-bath as ordinarily taken is of service for cleansing purposes, and if the water be cold it tones up the system to some extent, and is so a preventive against taking cold. The effect of this bath will be found to be vastly more beneficial if salt is added to the bath in the proportion of a pint of salt to a gallon of water; either sea-salt may be used or the ordinary coarse salt. It is most advantageously taken sitting in a bath or hat-tub, so that the entire surface of the body will be wet at the same time, and the water can be allowed to run down the back and over the chest. It is well to begin these baths at a temperature of 80∞ F. and to gradually decrease this until the bath is taken at 70∞, which is about the temperature of running water, and the bath should be kept up at this. For most people the best time to take the bath is just before retiring; this bath is not only very strengthening, but also is excellent in cases of insomnia and nervousness. Shower-baths.-- These may be taken after a hot bath, or taken alone after violent muscular exercise. The body should be quickly scrubbed off and the shower should be warm at the beginning and gradually allowed to become cold, stooping over so as to get the full force of the shower on the spine and over the region of the stomach and heart. They will be found to be most refreshing after great muscular fatigue, and, when taken after the hot tub-bath, greatly lessen the susceptibility of the individual to taking cold. Sitz-baths.-- These are given for their local effect in cases of inflammation; whether this inflammation be of the kidneys, bladder, or of the uterus and its adnexa. A sitz-tub is necessary to properly take this form of bath. The water should be used as hot as is comfortable to the patient, from 105∞ to 110∞ F., hot water being added as the first cools off; a pint of salt should be added to the gallon of water, and the patient should remain in this from five to eight minutes. A blanket should be wrapped about the patient so that she will be thrown into a perspiration; it is almost needless to say that the only time for taking this bath is just before retiring, and that this bath does make the woman more susceptible to taking cold, so that it is necessary to wear an abdominal woolen bandage day and night. Tub-baths.-- The tub-bath ought not, as a rule, be taken more than twice a week, unless the cold plunge is used, which may be taken every day. If the tub-bath is taken hot, the woman should remain in it not much longer than is necessary to scrub off with a flesh-brush; this bath should be followed either with a cold shower-bath, or the water in the tub be gradually allowed to cool off until it is down to 70∞ F.
