With respect to bathing generally, very erroneous opinions appear to prevail, two of which only we will notice:—First, that for delicate constitutions bathing is dangerous, because no reaction takes place in the system;—secondly, that it is dangerous to bathe in cold water when the body is heated. To the first we answer, that no matter how delicate the constitution may be, reaction can always be obtained, if water of a proper temperature be used; this temperature will vary with the vitality of the individual—the more delicate the individual the warmer the water must be. A delicate person will often receive the same shock and benefit to his system from water at a temperature of 80°, as a strong man may, perhaps, receive from water at a temperature of 42°. To the second we reply, that a more erroneous opinion could not by possibility prevail, and that the idea in question is exactly the opposite of the truth; the fact being, that the body cannot be too warm for cold bathing, always provided, that such warmth has not been produced at the cost of bodily languor and fatigue, as in such cases the system will be too much weakened to react after the bath with effect; but with this exception, the warmer the body the greater will be the reaction and benefit received, and the longer may the bather continue with impunity to luxuriate in the bath. The body is never so well calculated to withstand the effects of cold as when it is heated; and the only danger to be apprehended from cold bathing is that arising from entering the water in a chilled condition, when, from the low vitality of the body, the subsequent reaction becomes imperfect. Let these maxims be remembered:—that without subsequent reaction, no bath is beneficial—therefore, water should be always used of a proper temperature to secure reaction, and exercise to warmth, taken immediately before and after a cold bath, when practicable; that the colder the bath (provided reaction follows) the greater its benefit, the reaction being always a mean proportional between the temperature of the bather and the water in which he bathes. Whenever bathing is found to disagree with any person, it will be always found that some of the preceding conditions have been neglected, a very common fault being that of entering the water in a chilled state, and remaining there for twenty minutes, when five would have proved, perhaps, more than sufficient; then headache, languor, and chilliness succeed, and we are told that bathing disagrees. With such bathing, the wonder would be that it did not.
