As the weight of the body is increased from half-a-pound to a pound and a half, while immersed, there can be no doubt that a considerable absorption takes place. At above 98°, or blood heat, the bath excites the pulse and renders it both full and hard—embarrasses the breath—flushes the face—reddens the whole surface of the body—excites perspiration—powerfully draws the circulation to the skin—and not seldom causes head-aches, vertigo—and even apoplexy. Douches and shower-baths are often ordered before the plunging or vapour-bath. Lavements of the spa-water are also employed—and it is said with good effects, relieving the stomach from the ingurgitation of so much fluid. Preceding, and sometimes during the cure, the following phenomena occur in a majority of cases, in addition to those already described:—viz. a prostration of strength—headaches—giddiness—constriction over the eyes—drowsiness. In some cases, there will be constipation—loaded tongue—loss of appetite—oppression about the chest—feebleness of the limbs—nervous irritability—disturbed sleep—perspiration—palpitations—eruptions on the skin. These symptoms are acknowledged by the spa-practitioners themselves to indicate an inconvenient use either of the baths or the drink—or some abnormal susceptibility of the constitution—or some impropriety of regime. They soon disappear by lessening the application of the remedy, and taking some aperient medicine—an omission, however, which most of the spa-doctors are sure to make, trusting, as they do, almost entirely to the operation of the waters. It is necessary to remark that, the rheumatic and gouty who resort to these waters, (and they are by far the most numerous classes,) must expect to suffer a considerable increase of their complaints at the commencement—amounting often to acute pain and even inflammation of the parts affected. The local medical authorities represent these as the sure precursors of great relief, if not a radical cure of the maladies in question. I would advise patients to be on their guard in this respect. The first two individuals whom I fell in with at Wisbaden, and whom I formerly attended, were in imminent danger of their lives, from the effects of drinking and bathing in the waters. One was on the verge of apoplexy—and the other in a fair way for a rheumatic fever. Both were soon relieved by aperients, colchicum, and starvation.[14] There is another class who experience no uncomfortable symptoms during the use of the waters, which operate by the skin, the kidneys, and the bowels—and these proceed quickly and favourably to a restoration of health. There is still a third class who experience no relief from the waters, but rather an exasperation of all their maladies. The spa doctors give them this consolation, that, long after their return to their homes, they will probably get much better—or quite well! The following passage from Dr. Peez, should awaken precaution.
