Water Filter Information

What does water do in our bodies and why does it make a difference what kind of water we drink? Is a water filter worth its price and truly necessary?

Read on to find out how much you know about that life-giving fluid: water.

Some Basics

Although water contains no calories, it is absolutely essential for maintaining energy levels, regulating body temperature, controlling cravings, and cushioning sensitive organs, tissues, and joints within the body. In essence, water is the major means of transport for all substances in and out of the body.

It is necessary to continuously replace water in the body as such a large amount of water is expelled from the body each day through simple respiration. While a person may live for four weeks or more without food, he or she will only live for approximately one week without water.

Benefits of Drinking Water

Many cravings for food are often misdirected cravings for water. Once the body is satiated with the needed drinking water, cravings are greatly reduced. Water can also serve as a natural protection against several types of cancer.

When a person becomes dehydrated (meaning he does not have adequate amounts of water in his system to ensure proper body functioning), the symptoms of dehydration quickly appear. These symptoms include, but are not limited to: fatigue, headaches, difficulty concentrating, and constipation.

How Important is Clean Drinking Water?

Water is something of an interesting substance. It is a natural solvent; therefore, wherever water travels, it dissolves and carries along other substances. While the natural solvency of water is one of its most valuable characteristics (due to the usefulness of this characteristic in allowing water to carry and dissolve food nutrients for use in the body), it can also be one of its most volatile and dangerous characteristics.

We cannot simply cut water out of our diet, despite its penchant for carrying contaminants with it; water is far too essential to our survival. We will likely never receive pure, clean water directly from the tap, but a home water filter can remove several of the most dangerous contaminants from that water before we drink it. A water filter can help to ensure that we get all of the benefits of drinking water and none of the consequences of drinking contaminated water.
