DRINKING WATER can be health-giving, unwholesome, yellow, laxative, mournful, sulphurous, green, black, blue, fat, thin and greasy.
The truth is, the water you drink today perhaps has few of these qualities. In our day, about half a billion people are said to be constantly ill because of the water they drink. Ten million of them may die each them.
Even developed nations, that take pride in their “safe water” are now having problems. What a surprise! “It seems that everything that makes life easier makes water dirtier,” according to one U. S expert.
Life Depends on It.
Water remains of the most marvelous and very essential substances’ known. The very existence of life itself on earth solely depends on water.
Important to note that water is the main ingredient of most living things. The human body depends on water. About two-thirds of your total weight is water, while as much as three fourths of your brain and muscles are.
It is obvious that life functions best within the narrow temperature range in which water exists as a liquid.
Such an environment where life could exist is said to be practically non-existent elsewhere in the universe.
Water at Work Within You.
Blood is over four fifths water. No wonder blood is equated with the very life of creatures, as in the term lifeblood.
The unique qualities of water make it ideally suited as the basis of this life-giving fluid. For example, water has the unique ability to move freely back and forth through your body’s cell walls, carrying with it the chemicals of life.
Water also serves as the medium in which complex chemical reactions take place within the cells.
Water helps to control your body temperature. Rapid circulation by way of the bloodstream keeps heat relatively even all over and quickly moves excess heat to your skin for radiating into the air.
On the hand, heat stored in your body’s water delivers welcome warmth to the extremities when you are cold.
Despite this remarkable system, your body usually does not quickly enough get rid of the heat that it generates. Therefore, another amazing property of water comes into play-evaporation. How does this help?
When a pint of water evaporates, it soaks up about 1,100 times as much heat as when it’s temperature rises just one degree! You feel this cooling effect when a breeze dries moisture from your skin.
Since about two pints of body water normally evaporate unnoticed each day through your skin and lungs by means of your breath, much excess heat is regularly released in this way.
But on a hot day, or as your activity picks up from normal levels, your sweat glands exude more water, possibly gallons in a day. Any perspiration that evaporate from the surface, rather than dripping off, carries with it immense amount of heats- surely a marvelous cooling system!
Your Need for Water!
We need to keep our body well supplied, since water is so much a part of our very existence.
Though a person may survive as much as eighty days without food, few can last longer than about ten days without water. With a very small drop from normal water content, you quickly feel thirsty.
Even a 1- or 2-percent deficiency of water can be distressing or painful. Just 5 percent causes skin shrinkage, dried-out mouth and tongue, and hallucinations begin. A 15-percent loss is usually death-dealing.
Your body is constantly losing water. In addition to the pints normally lost through the skin and breath, another three pints or more may be eliminated through your kidneys and bowels.
Water lost by sweating, and even by tears, has to be added to the normal total of five or six pints that must be replaced each day to maintain your body’s fluid balance.
Does this mean that you have to drink three quarts of liquid daily? Not unless you are sweating heavily. The truth is, about a third of the water you need comes from eating a solid “food”, which is often mostly water. Even bread is about third water.
Thus, you may need to drink only five or six glasses of liquids such as coffee, milk, juice or water directly each day. But even though water is among the most abundant substances on earth, supplying enough drinkable water is a major undertaking.
Making Water Drinkable!
Drinking water can seldom be called “pure” or “clean” in a chemical sense, because it almost always has some gases and minerals dissolved in it.
Making water safe to drink and pleasing to the taste does not require removal of all impurities. In fact, some elements necessary to good health and taste are often naturally in good drinking water.
Fresh underground water obtained from springs and Wells is often but not always safe to drink because of the filtering and purifying that takes place as it sinks through layers of soil and porous rock. Fresh water also have self-purifying abilities.
Dissolved oxygen is vital to an amazing step-by-step digestion process that occurs in both moving and still waters. The oxygen may directly oxidize or burn wastes, neutralizing them, or more often, it supports bacteria that break down wastes to a harmless residue.
As the process continues, tiny life forms consume the bacteria, clearing the water further. Small water creatures feed on the algae, completing the “digestion” cycle. In this way fresh waters tend to purify themselves in time.
Water as Medicine.
Children who drink treated water reportedly have only half to a third as many dental cavities. But opponents cite the fact that the majority of people do not benefit, since it admittedly helps only youngsters.
Though most medical authorities discount such charges, those who oppose fluoridation say that they should be free to choose.
Some fled to bottled water for safety. Recent studies indicates that even some bottled waters aren’t safe. It is suggested to boil your water as it will drive off any free chlorine.
It is wise to have a balance view of the water we drink. The air we breathe is polluted enough to shorten life in some areas, but gas masks are impractical.
