If the water is very hard, heavily loaded with salts, it should not be used extensively as a drink, for if too much of earthy and mineral matter is taken into the system, the body is unable to get rid of all of them. The result is a tendency for deposits to form in the body. In places where the water is excessively charged with lime it has been noticed that the bones harden too early, which prevents full development of the body. If the bones of the skull are involved, it means that there will not be room enough for the brain. Such diseases are rare in this country, but in parts of Europe they are not uncommon. If the water is very hard, a good plan is to distill it and then add a little of the hard water to the distilled water. 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. The water is the vehicle through which the nutritive elements are distributed to the billions of cells of the body, and it is also the vehicle which carries the waste to the various excretory organs. We can live several weeks without food, but only a few days without water. Hot water and ice-cold water are both irritants. Water may be taken either warm or cool. It is best to avoid the extremes. The amount of water needed each twenty-four hours varies according to circumstances. Two quarts is a favorite prescription. Those who eat freely of succulent fruits and vegetables do not need as much as those who live more on dry foods. Salt in excess calls for an abnormal amount of water, for salt is a diuretic, robbing the tissues of their fluids and consequently more water has to be taken to keep up the equilibrium. Naturally, more water is required when the weather is hot than when it is cool. On hot days warm water is more satisfying and quenches thirst more quickly than ice water. Warm water also stimulates kidney action, which is often sluggish in summer. Ice water is the least satisfactory of all, for the more one drinks the more he wants. A normal body calls for what water it needs, and no more. An abnormal body is no guide for either the amount of food or drink necessary. Many people do not like the taste of water, especially in the morning. This means that the body is diseased. To a normal person cool water is always agreeable when it is needed, and it is needed in the morning. People with natural taste do not care for ice water, but other water is relished.
