For cleansing purposes the so-called half tub, that is, the tub contains a sufficient amount of water to reach above the pelvis when one is seated in the tub, is used. The temperature ranges from 98° to 102° F. Five minutes is as long as the bather should remain in the tub, as all hot baths are more or less exhausting. After an initial immersion in the water, the scrub takes place by means of the Turkish bath-towel, or, better, by the use of the flesh brush. If there is a shower attached, the hot bath should always be followed by a brief cold shower; if not, the cold water should be turned on and dashed over the body by means of the wash-towel. This closes up the pores of the skin, prevents the profuse perspiration from taking place that so often follows a hot bath, and greatly diminishes the susceptibility to taking cold. An alcohol rub completes the procedure. This insures a further toning up of the cutaneous vessels. A small quantity of alcohol is poured into the hand and applied to a limited area of the body. It is well rubbed in with friction until the alcohol has wholly evaporated. Beginning with the arms, the legs, chest, and back are successively gone over. The hot bath is best taken immediately before retiring, and should not be repeated oftener than twice a week. Retiring to bed at once, the bed acts as the cooling chamber of the Turkish bath. The hot bath is most restful, and, except in rare cases, tends to the production of refreshing sleep. If the bather has a weak heart, suffers from shortness of breath, or is weak from any cause whatever, she should only take a half tub bath, since it has been learned from experience that when the water covers the entire body, there is increased difficulty in the respiration, and the heart’s action often becomes embarrassed, palpitation of the heart is experienced, with a feeling of impending suffocation. There is sometimes also a feeling of faintness. On getting into the tub, the temperature of the room should never be above 68° to 70° F. _The Full Tub or Immersion Bath._—In this form of bath there is a complete submersion of the body in the water, so that the water reaches the under surface of the chin, the head of the bather resting on a cross strap, being the only portion of the body uncovered by the water. If the bath is tepid, that is, has a temperature of from 80° to 90° F., great care should be taken to have the chest covered, in order to prevent pulmonary congestion. This is best accomplished by placing a Turkish towel, wrung out of hot water, about the chest and shoulders of the bather just after she enters the tub. If the bath is hot, from 98° to 104° F., before entering the bath the face and neck are rubbed with cold water, in order to relax the vessels of the brain and so prevent cerebral anemia. Except when the hot bath is given for especial therapeutic purposes, as for rheumatism, cystitis, colic, etc., it should always be followed by a cold application.
