The waters of the Maxbrunnen remain clear when heated. The others become a little turbid by the heat. Patients are recommended not to bathe in any of these waters for three or four days after their arrival. They should be taken for some days internally, before the baths are used, in order that the bowels may be free, and the secretions improved. They ought to be employed to the point of saturation—which generally takes place in a shorter time than by the drinking of the waters. The baths are taken before noon, and after drinking the waters, before breakfast—or in the evening. The baths, however, may be taken two hours after a light breakfast—and are more agreeable to most people at this time than before the repast. Once a day is often enough. They are generally raised to 96° or 98° of Fahrenheit—and half an hour is the usual period of immersion. It is prudent not to stay in more than ten or fifteen minutes at first, and to gradually increase the period, till it comes to thirty or forty minutes. “Patients who are disposed to convulsions, vertigo, faintings, or fulness about the head, should not use these baths but with extreme caution. Such people ought to keep the head covered with cloths wet with cold water during immersion.”[58] These baths are absolutely prejudicial, if the patient goes in when heated, perspiring, or excited by passions of the mind. The bather ought not to plunge at once into the bath, but first to sponge the chest and stomach with the warm water. It is hurtful to read in the bath, and more so, to go to sleep. On the contrary, the bather should keep in constant motion, to use friction with his own hands over the chest and abdomen. “If, during immersion, the patient be seized with feverish heat, chilliness, shivering, head-ache, oppression on the chest—or any kind of malaise, he should immediately quit the bath, and examine whether or not the temperature has been too high or too low. He should dress himself quickly on leaving the bath, and take some turns in the dressing-room before going into the open air. Gentle exercise after the bath is very beneficial.” The point of saturation from the baths is considered by Dr. Balling as a matter of great importance. This point is not attained till the morbific matters are expelled from the constitution, and all the secretions have become healthy and natural—especially those from the intestinal canal. The time necessary for attaining this desirable condition will be different in different constitutions—and in different diseases. Generally speaking, it requires two weeks of the bath. After this period the patient and physician should be on their guard, and watch well the phenomena as they occur.
