I advise the drinking of a copious quantity of water daily. There need be no fear that this practice will thin the blood too much, as the ready elimination of the water will not permit such a result to ensue. I would further advise the generous use of water (temperature 60°) at meal-times. I pray you do not drink to wash down food: a bad habit of most of us. Drink all you desire; and if you are like many who have no desire for water, cultivate it, even if it takes years. The imbibed water will be in the tissues in about an hour; and the entire quantity will escape in about three and one-half hours. The demand on the part of the system for water is subject to great variation and is somewhat regulated by the quantity discharged from the organism. Physiologists declare that water is formed in the body by a direct union of oxygen and hydrogen, but those who have cultivated the drink-little habit need not hope to find an excuse for themselves in this fact: chronic ill-health betrays them. Water in organic relations with the body never exists uncombined with inorganic salts (especially sodium chloride) in any of the fluids, semi-solids, or solids of the body. It enters into the constitution of the tissues, not as pure water, but always in connection with inorganic salts. In case of great loss of blood by hemorrhage, a saline solution of six parts of sodium chloride with one thousand parts of sterilized water injected into the system will wash free the stranded corpuscles and give the heart something to contract upon. When water is taken into the stomach, its temperature, its bulk, and its slight absorption react upon the system; but the major part of it is thrown into the intestinal canal. When it is of the temperature of about 60° it gives no very decided sensation either of heat or cold; between 60° and 45° it creates a cool sensation, and below 45° a decidedly cold one. Water at a temperature of about 50° is a generator of appetite. A sufficient quantity should be taken for that end; say, one or two tumblers an hour or so before each meal, followed by some exercise. Those who have acquired the waterless habit, and the many ills resulting from it, will hardly relish cool water as an appetizer; but if they would become robust they must adopt the water habit--a habit that will refresh and rejuvenate nature. Water of a temperature between 60° and 100° relaxes the muscles of the stomach and is apt to produce nausea, especially if the effect of bulk be added to that of temperature. Lukewarm water seems to excite an upward peristalsis of the intestines and thus produces sickness.
