It is said that water is the ideal drink for the human being, and that drinking water is good for one's health. The reasons why this would be the case, however, are rarely stated. As a consequence, water, as a drink, is often neglected as a factor in health.
Who could imagine that fatigue, energy depletion, depression, eczema, rheumatism, high and low blood pressure, high cholesterol, gastric disorders, and premature aging could all be caused by a chronic lack of water in the body? Science has discovered that these problems – and a great many others – can be effectively prevented or treated by correct hydration.
Most people assume they are drinking enough fluids. Certainly they consume copious amounts of coffee, tea, and all sorts of soft drinks, but these beverages are far less effective in hydrating the body than plain water. Furthermore, in today's world, our bodies' need for water is much higher that it once was. Our food is too rich, too concentrated, and too salty, and the use of dehydrating substances such as alcohol and tobacco is very widespread. Stress, overheated and artificially ventilated homes, offices, and stores, air and water pollution – all contribute to our increased need for water.
As a consequence, large numbers of people do not realize they are chronically dehydrated, much less that lack of water is the cause of many of their health problems. There is only one solution: drink a lot more water. But for people to make a permanent change in their habits, they need to know why water is so important. What exactly happens when water enters in the body? What are the health conditions that can be traced to dehydration? How much should we drink, and what water should we choose? Theses are just a few of the many questions answered in this book.
The Harm Caused by Dehydration
Our bodies are constantly dealing with liquid deficiencies.
Every day we expel 2.5 liters of water from our bodies in the form of urine, sweat, water vapor from the lungs, and the liquid contained in stools. When an equivalent intake of water is maintained, the body's hydric budget is in balance. Conversely, if the liquid intake is insufficient, this balance sheet goes into the red, and the process of dehydration begins.
The dehydration of the body can occur quite quickly. Although human beings can survive for a fairly long period without food (more than six weeks, as is shown by certain therapeutic fasts), the same does not hold true for going without liquid. Three days without any liquid, either in the form of drinks or what is bound to solid food, is sufficient to create serious physical breakdowns. Two or three days longer is fatal.
