Cold water is sometimes of use when locally applied, and seems to act as a wholesome stimulant to parts which have become stiffened by want of use, such as strained and sprained joints. In some skin diseases benefit will be derived by the use of cold water. This is particularly the case in itching of the skin or _Prurigo_, and _Acne_. Warm baths are far more generally useful in diseases than cold baths. For the removal of the thickenings around joints, which have been caused by gout or rheumatism or “rheumatic gout,” bathing in tepid or hot water is justly considered as a powerful means of alleviation, and as a valuable accessory to treatment by diet and regimen. The hot water of Bath and the tepid water of Buxton have long enjoyed a great reputation for gout and rheumatic gout, and there are many baths on the Continent, which have a reputation, equally high, in the treatment of these affections, such as _Teplitz_, _Gastein_, _Wiesbaden_, and _Wildbad_. The treatment of gout by bathing is usually aided by the internal administration of mineral water, but into this question we are unable to enter, notwithstanding its great importance. For exudations round joints, which have arisen from causes other than gout and rheumatism, warm bathing is of very great service, as well as in relieving the stiffness and thickenings which sometimes occur as the result of severe wounds. For _paralysis_ warm bathing is often of great use, provided the cause of the paralysis be a removable one. Formerly, the principal method of treating cases of lead paralysis occurring in the cider counties of the West of England, was the sending of the patient to the warm springs at Bath, and the results were generally very good. There are many forms of paralysis which could not be benefited by treatment with hot water or anything else; but it is impossible, in an elementary treatise, to enter into a question requiring a high degree of medical knowledge for its proper appreciation. For neuralgia, sciatica, lumbago, and many forms of muscular rheumatism, hot bathing may be employed with advantage. For Bright’s disease of the kidneys, warm baths, vapour baths, and Turkish baths, are all employed with benefit. An occasional Turkish or hot bath is a very great aid to the well-being of dwellers in cities who get an insufficiency of air and exercise, since it produces an activity of the skin which can only be brought about by such means or by violent exertion. A common cold may sometimes be cured by means of a Turkish bath. To bring about this result, however, the treatment must be applied in the very earliest stages of the disease, when the slight tension in the head, or a trifling feeling of chilliness, is warning the patient of his coming trouble, and before the running of the eyes and nose has thoroughly set in. A Turkish bath in this very earliest stage of a cold will sometimes cut the disease short, but such a result is, unfortunately, by no means invariable.
