We know that emetics produce this effect, but such remedies weaken the stomach—while water has the contrary tendency.
Cold water, as a beverage, fortifies the stomach and intestines, by clearing them of the bad juices they contain: favours the generation of new juices, and mixes with the blood by absorption. It spreads itself quickly through all the organs, attenuates, purifies, and dissolves the sharp or thick humours, and discharges them by means of perspiration and urine. Considered as a dietetic for slight indispositions, bad digestions, and generally in all cases of disease for which the faculty recommend aperients or mineral waters, it cannot be too highly appreciated. In the morning, after a cold ablution, whilst taking exercise, drink a few tumblers of water, and conclude every meal with a tumbler of water. It will have the same effect as a purgative or mineral water, without, like them, weakening the digestive organs. All persons may drink cold water at all times of the day with impunity, if they are not inconvenienced by it. That taken before breakfast, during exercise, produces doubtless the best effects. It is above all after sweating that drinking cold water produces an expectoration of phlegm. Water may be drunk after breakfast, but not so as to overcharge the stomach. During dinner the aliments should be moistened by some glasses of water, then the stomach must be left to repose; some hours afterwards again water may be drunk until supper-time. Drinking after supper is no less useful; but it may break the rest, by causing an invalid to rise often in the night. After drinking, exercise is indispensable, it stimulates the action of the water, and accelerates a cure. When in exercise, though in a perspiration, water may be drunk in any quantities. Water ought always to be drawn fresh from the spring, and drunk as cold as possible. The decanters which contain it ought to have stoppers, to preserve it cold and fresh. After every operation in the cure, a glass of water should be drunk; and it should be given in small quantities when in the sweating process. I know a gentleman who has all his life been a free-liver, and who, notwithstanding, is in good health, which he attributes entirely to drinking a couple of tumblers of water the last thing at night and first thing in the morning.
Under the denomination of injections, we principally understand clysters. When the patient is not in the habit of using them with cold water, they must not at first be applied for longer than two minutes; but by degrees the intestines become accustomed to the water, which is often absorbed like that introduced into the stomach. When necessary, a second injection is repeated immediately after the expulsion of the first.[4] Cold injections are used for constipation and diarrhoea, two diseases diametrically opposite, but which arise from the same cause, the weakness of the intestines. Thus the contradiction is only in appearance, the great object of injections being to establish the tone of these organs, and regulate their functions. Injections ought to be aided by the use of cold water in other ways.
There are also other injections in use at Gräfenberg, such as for the ears, nostrils, and genitals. Particular syringes are used for these purposes.
XI.—The Cold Bath.
The cold plunge-bath should be sufficiently deep for a man of ordinary height to plunge into, up to his arm-pits. The water aught[sic] to be continually renewed by a spring.
We have quoted many authorities to shew the advantages resulting from exposing the body to the action of cold water.
When cold baths disagree with us, it is because we are not in a state to use them, or we stay in too long.
When the body is overcharged with drugs or alcohol, when the juices are dried up, or when there is an apoplectic tendency, and when in other diseased conditions, the circulation is languid, cold plunge-baths must be used with great caution. Many suppose that all the patients in a hydropathic establishment, are indiscriminately ordered this sort of bath. In this they err, because many are never allowed their use, and others only after a long application of the rubbing sheet and tepid baths. Strong robust constitutions may take the plunge-bath at once; but in the Water-cure this is not allowed until the body is prepared for it, and then only for a short time; generally for three or four minutes. Priessnitz objects to persons staying long in the water: of course the objection applies to invalids. For those who bathe in the sea, or other water, he does not pretend to prescribe.
