Hydration

“ When it is remembered that nearly two thirds of the substance, by weight, of the human body is in the form of water, included in the composition of the various tissues, the importance of using water in liberal quantities internally becomes at once apparent. The most eminent physiologists have computed that, in order to supply the losses by excretions and evaporation taking place in the human body, it is necessary to drink from a half to one gallon of water daily. This, too, in addition to the water contained in the beverages, such as tea, coffee, etc., which are in common use. ”

“ In the case of medicated baths we therefore only look (in addition to the action of heat and cold, or more properly to the abstraction or communication and retention of heat) to any stimulant action on the skin that the ingredients of the bath may possess.
The powerful influence of water on the capillaries of the skin, and the mode and extent of that operation, depend primarily on the temperature of the fluid. The human system bears changes of temperature of the air much better than changes of the temperature of water. ”

“ Distilled water is the nearest approach to pure water obtainable, and it is said by physicians that such water is not desirable as a habitual and constant beverage. The human body requires certain mineral salts particularly for the bones and muscles, and while these salts are provided in a large measure by food, a number are also furnished [Pg 132] by drinking water. On the other hand, a wonderful natural process is accomplished by distilled or approximately pure water in that the water tends to dissolve, to add to itself, and to carry away whatever excess of solids may exist in the body. ”

“ It has been estimated that an average-sized adult loses by means of the lungs, skin, and kidneys about eighty ounces of water every twenty-four hours. To restore this loss about four pints must be taken daily. About one pint of this is obtained from the food we eat, the remaining three pints being taken as drink. One of the best ways of supplying water to the body is by drinking it in its pure state, when its solvent properties can be completely utilized. The amount of water consumed depends largely upon the amount of work performed by the body, and upon the temperature. ”

“ Value of Water.—As a rule the work of excretion is aided by drinking freely of pure water. As water is the natural dissolver and transporter of materials in the body, it is generally conceded by hygienists and physicians that the taking of plenty of water is a healthful practice. People do not as a rule drink a sufficient amount of water, about three pints per day being required by the average adult, in addition to that contained in the food. Most of the water should, of course, be taken between meals, although the sipping of a small amount during meals does not interfere with digestion. ”

“ The mucous juices are dissolved like every other fluid; for wherever there is atmospheric air, heat and moisture, there is evaporation. Here this evaporation is even a means which nature employs to rid herself, as I have said, of the mucous juices. If they are too abundant, as in a cold, then the quantity of air which serves as a vehicle to them, not increasing in proportion, it is necessary that there should be another mode of evacuation; this is expectoration which compensates for what the air cannot remove by solution. ”

“ WARM WATER.—Warm water is preferable to cold water, as a drink, to persons who are subject to dyspeptic and bilious complaints, and it may be taken more freely than cold water, and consequently answers better as a diluent for carrying off bile, and removing obstructions in the urinary secretion, in cases of stone and gravel. When water of a temperature equal to that of the human body is used for drink, it proves considerably stimulant, and is particularly suited to dyspeptic, bilious, gouty, and chlorotic subjects. ”

“ The water in contact with the part, being of a lower temperature, abstracts heat from it as it would from any other body of a higher temperature than itself.
When the application of cold water is more general, being made to the whole body, or to a considerable portion of it, the same effects are produced on a larger scale. A large proportion of the small arteries of the body, being brought under the influence of cold, are made to contract, thus directly lessening the circulation, and so diminishing, also, the production of heat. ”

“ People who partake of an excessive amount of various salts can perhaps drink distilled water to advantage, but those who take but a normal amount of the salts in their foods should have natural water.
Water forms three-fourths of the human body, more or less. It is needed in every process that goes on within the body. "To be dry is to die." Water keeps the various vital fluids in solution so that they can perform their function. Without water there would be no sense of taste, no digestion, no absorption of food, no excretion of debris, and hence no life. ”

“ 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. ”

“ The proportions of water are not always quite the same, nor does the identical water present in any part of the body at any given moment remain there. There is a constant movement, a continual renewal going on in the body, and water helps to accomplish this renewal. By means of the watery substances, the saliva, the bile, and other juices of the stomach and intestines, the solid nutritive parts of the food are dissolved, and pass into the blood to renew the waste, and to keep up that continual current called life. ”

“ 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. ”

“ The water must be taken one hour before meals, in order to insure its removal from the stomach and the proper rest of that organ before food enters it, as it has been found by actual experiment that in a quarter of an hour after water had been taken one-half of the quantity remained in the stomach, but that none remained after the lapse of half an hour. Cold water is more quickly absorbed than warm, and the absorption is hastened by the presence of carbonic acid, while salt of any kind delays its absorption. ”

3. Boiling. A simpler and equally efficient method for purifying water for drinking purposes consists in boiling the water. It is the germs in water that render it dangerous to health. These germs are living forms of matter. If the [Pg 53] water is boiled, the germs are killed and the water rendered safe. While these germs are destroyed by heat, cold has little effect upon them. Thus Dewar, in working with liquid hydrogen, exposed some of these minute forms of life to the temperature of boiling hydrogen (-252°) without killing them. ”

“ Meanwhile, it must not be forgotten that thirst is Nature’s call for fluid to replace that lost by cutaneous exudation in warm weather; and if the demand be not met, what may be regarded as the residual fluid of the tissues must be absorbed, or the blood will become unduly concentrated. To thirst and drink, and perspire and drink again, are the natural steps in a process by which Nature strives to maintain the integrity of those organic changes which the external heat has a tendency to impede. The natural and true policy is to supply an adequate quantity of fluid without excess. ”

“ WaterWater helps to regulate the concentration of the minerals in the body and carries food to the tissues by holding the food materials in solution in the body fluids. It also is invaluable in helping to carry off the body’s wastes and assists in regulating the body temperature. Four to eight glasses of pure water every day make for health. ”

“ There is no other single remedy that I consider so valuable in the treatment of fever as the internal use of water. As above stated, the patient should drink six or eight ounces every hour during the waking hours, except for about two hours after food is taken. The water should be thoroughly sterilized, and as a rule may be taken either cool or hot. Ice water is objectionable. Hot water is often preferable. This is a simple remedy, but nevertheless is efficacious. ”

“ They will not, however, any more than red paint will act as an antidote to poor health by painting the cheeks with it. Water, hot water, especially when used plentifully, is the only solvent of dirt.
Very few realize how essential water is to digestion and to the digestive canal after the process of digestion is completed; and that it has physiological effects on the system generally is less widely known. There exists a great natural demand for water to carry on the normal functions of the system ”

“ The statement that free consumption of water at meals delays digestion by diluting the gastric juice is therefore not well grounded. In the blood, water serves to carry nutrient materials to all the tissues; and, at the same time being circulated all over the system, equalises the temperature, favours chemical changes, and washes all the tissues. By water again, the effete matters which have been separated by the kidneys are washed out of its tubes.
The Oxygen of the air, in a broad sense, forms one of the foods of the system. ”

“ In spite of all the care that we may take, we find it so difficult to keep water perfectly pure. It may have, for instance salt dissolved in it, or bits of grass and other decaying matter. Rain water is, of course, the purest, but, before it reaches us, it generally becomes impure by the absorption of the floating matter in the atmosphere. Perfectly pure water has a most beneficial effect on the system; hence doctors administer distilled water to their patients. Those who are suffering from constipation are appreciably benefitted by the use of distilled water. ”

“ Contraindications.—Cold water taken into the stomach produces more marked effects than water applied to an equal area of the skin. The quantity of water taken is a factor as well as the temperature. Cold-water drinking lowers the temperature and slows the pulse, so that drinking cold water must be strictly prohibited when one is in a state of fatigue, whether perspiring or not. Feeble persons should not drink cold water, except in very hot weather, or just before starting out for a brisk walk in the open air, or when about to engage in other exercise. ”

“ A sponge bath is less fatiguing than the tub. A salt bath (one third cup per gallon of water) is a tonic. It should not be used if the skin is irritated. Bran, starch, or soda baths relieve chafing, inflamed skin, prickly heat, irritation in eruptive diseases. To one gallon water use half a cup of clean bran, tied in cheesecloth and previously soaked; or a cup of ordinary raw laundry starch, or a tablespoon of baking soda. Alcohol bath, using one fourth alcohol, is cooling and hardening. Pure alcohol reduces heat too rapidly. ”

“ Lay it in a basin, pour boiling water upon it, and wring it dry by folding it in a dry towel. Or, if only one end of the cloth is wet, it may be wrung by folding the dry portion outside of the wet; in wringing, the whole will become equally wet. Apply it to the patient as hot as it can be borne. The second application can usually be made much hotter than the first. Frequently dipping the hands in cold water will enable the attendant to wring the cloth much hotter than he would otherwise be able to do. The most convenient way is to heat the cloths in a steamer ”

“ Truly, Pure Water alone, can be applied to fulfil two of the most essential indications in disease, which all the remedies in the whole medicinal pharmacopeia cannot fulfil.
By a judicious application of steam and hot-water we can relax any part of the system interiorly or exteriorly, and hence wash away extraneous materials. This remedy never fails to effect its indication; that is, if we place hot water into a living organism, or an organism into hot water, the result of heating is always certain. ”

“ Too prolonged an application may result in injury to the part.
153 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. ”

“ Let the patient be comfortably covered and seated, and wait two minutes or so. Add then a little hotter water, and every two minutes add a little more water, hotter every time, gradually increasing the quantity and temperature of the water. In half an hour a good strong heat and large deep bath will be reached, and in only a very few cases will there be any faintness. If the heat is raised too fast, give a little cold water to drink, and proceed more slowly. ”
