WATER-DRINKING.
As a remedial agent, water is of far greater value than any other liquid taken into the stomach. Its uses in preserving health have been previously noticed. Under ordinary circumstances, a person in health who discards irritating condiments from his diet seldom requires drink. Many persons take no drink whatever during the winter months. But drinking is healthful, and pure water of proper temperature may be taken by any one in health or disease if it is taken in the proper manner. Drinking at meals is an unwholesome practice. Drinking large quantities of iced water is unhealthful. Cold water should not be taken freely when the drinker is hot or exhausted. The thirst will be quenched as readily by slowly sipping a small quantity. In fevers, water should be freely allowed. A glass of cool water taken half an hour before breakfast is an excellent remedy for habitual constipation.
Water-drinking may be made a means of bathing the internal structures, as external applications bathe the outside. Water is rapidly absorbed by the mucous membrane of the stomach, and, passing through the circulation, it dissolves many impurities, and is eliminated chiefly by the kidneys and skin. It can be used with benefit in connection with the vapor bath, hot-air bath, and all baths in which sweating is induced. It should not be used in such great excess as it was employed by the early hydropathists, however, whose patients drank from ten to thirty glasses of water a day.
Free drinking of water is useful in cases in which the urine is scanty and irritating. It gives relief by diluting the urinary excretions.
