PLUNGE BATH.
The hot baths of the ancient Greeks and Romans were usually followed by a plunge up to the neck in a large basin of water four or five feet deep, and large enough to allow the exercise of swimming. Many hydropathic establishments employ the same bath after packs and sweating baths. A bath of this kind is not always attainable without great expense; and it possesses no particular advantage over other methods of cooling the surface after a warm bath. It is a very severe form of bath when employed at a low temperature. In the days of Priessnitz, it was used at a temperature of 45° or 50°. More harm than good would result from a continuous employment of such treatment. The cool plunge should be of but a very few minutes’ duration, and the patient should rub himself vigorously during the bath. In this, as in all other cool baths, the first contact with the water produces chilliness or shock. After two or three minutes, or less, this will be followed by a partial reaction, even while the patient is in the water, accompanied by a feeling of comfortable warmth. This will shortly be again succeeded by a second chill, which is not so likely to be followed by prompt reaction; hence, the patient should always take care to leave the bath before the occurrence of the second chill, if he would avoid unpleasant after-effects.
