Why Do We Need Water
It may seem like a silly question but in a number of forums and discussion groups, you will find someone asking, "Why do we need water?" However, this is a question we should all know the answer to.
Water is an essential element for human survival. In fact, apart from air, water is the most important element needed to ensure one's survival.
When answering the question why do we need water, it is important to consider the uses of water in the human body. Our body is made up of about 70% water. Moreover, 80% of the brain is made up of water. Therefore, the lack of water can cause all sorts of problems to our entire body due to dehydration.
Water has a number of uses in the human body. One essential use is in flushing out toxins. These toxins may be the by-product of metabolic processes or it could be the unwanted materials that result from digestion. Either way accumulation of such toxins in the body affects cell health. As such, there is a need for these toxins to be flushed out of the system. Drinking plenty of water ensures such toxins are flushed out of the body system in the form of body waste and sweat.
Due to the numerous cell functions, the body requires a constant supply of water to ensure that it functions efficiently. The body loses water through processes such as perspiration and respiration. Moreover, a lot of water is lost through excretory processes such as urinating. To compensate for this loss, one has to consume large amounts of water on a daily basis.
This brings us to the question,"why do we need water for survival?" Just like the first question, it is quite common. The human body will last only three or four days without water in ideal conditions. However, chances are that the body won't survive even for this period without water if external conditions are extremely hot or cold. Failure to replace water lost through the different processes leads to dehydration. One starts to experience headaches, tiredness as well as loss of concentration and gets worse quickly. If no water is available to furnish the fluids that your organs need to function, your body will begin to shut down.p>
Basically, we need water because the body is unable to store water within its cells. When dealing with survival situations, one will have to obtain water from any source available. However, in order to do so safely, one will have to know a few water purification techniques. Some of the basic water purification techniques useful for survival include filtration and boiling.
