The very hot bath (110° to 115°) produces quickly a general excitation of the circulation and sensibility, like all other hot waters. It augments the secretions, ending in considerable perspiration—and followed ultimately by relaxation in the muscular and fibrous systems, and a general softening of all the solid parts. When the bath is very warm, we have often, in addition to the foregoing phenomena, oppression at the chest—anxiety—palpitation—vertigo—dimness of sight—heaviness about the head—syncope—and even apoplexy. It need hardly be added, that baths at such a temperature as to induce the foregoing train of symptoms, are very dangerous, and hardly ever necessary. But even at a moderate temperature—96° or 98°—these baths produce, after a few days, sleeplessness, constipation, great disposition to perspiration, emaciation, susceptibility to cold or damp, aggravation of gouty or rheumatic pains, the aching of old wounds, prostration of strength, &c. These occur about the eighth day, and, after more or less duration, gradually disappear. After this period, there generally appears an eruption on the skin, of a whitish yellow or red colour, accompanied by considerable itching, discharging a watery humour, and finally desquamating, with occasionally some fever. If the baths be continued longer, the prostration and lassitude increase, accompanied by great irritability and moroseness, loss of appetite, furred tongue, nausea, fætid eructations, repugnance to the bath, wandering pains in the limbs—in fine, fever is kindled up, with inflammation of the mucous membrane of the stomach and bowels. This is what the Germans call “DAS UEBERBADEN,” or over-bathing—and occurs after eighteen or twenty baths—sometimes not till after forty or sixty. Dr. Richter conceives that, in all cases where it is deemed proper to stimulate the circulation and the lymphatics—to rouse the energy of the nervous system when paralyzed—to excite strongly the functions of the skin—to depurate bad humours—to expel a morbid principle from the constitution or the internal organs—to relax contracted tendons or muscles—to reduce abnormal or morbid growths—it will be necessary to have recourse to the HOT baths of Teplitz, watching their effects, and moderating their action from time to time, according to circumstances.
