These baths commonly produce a febrile action, easily recognised by the redness of the skin, heat, and burning thirst, extreme debility, difficult respiration, stupor in some, and obstinate wakefulness in others. The perspiration being thus augmented, all the other secretions are diminished, especially milk and urine. The senses become deadened, and the flesh is in general more flabby than common. In this state of things, perspiration after a while ceases, nor could it be renewed if the heat were augmented to 144° of Fahrenheit.
The dry bath, from 140« to 144° of Fahrenheit, is more supportable than a moist vapour bath of 117° to 122° of Fahrenheit. The Finlanders were formerly in the practice of rolling themselves in the snow, but at present the custom is almost universally abandoned. In Carelia, Tevastia, Savolax, it is customary to bathe every day—in Nieland less frequently.
