Water Is The Essence Of Life

by Optimum Nutrition Admin

Plenty of clean water is absolutely essential for maintaining even marginal health.

One of the two most important components for obtaining and maintaining optimum health is proper hydration (the other being proper nutritional intake). Water is the building material for every one of our trillions of cells and facilitates every chemical reaction and bioelectrical signal within. It acts as both a solvent and a delivery mechanism, dissolving essential nutrients such as vitamins, minerals and glucose from food and delivering them to every cell in the body. Our bodies use water to flush out toxins the organs’ cells reject and eliminate them through urine and feces. Water has a large heat capacity which provides for efficient body temperature regulation. When sufficiently hydrated, the body is able to release heat when the ambient temperature is higher than the body’s temperature. Evaporation of water emitted from the skin’s surface (sweat) cools the body and aids metabolism. Water is a phenomenal lubricant for our joints and also acts as a buffer, or cushion, for the eyes, brain and spinal cord. Approximately 96% of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen with the majority in the form of water. A person possessing ideal health has a body consisting of over 70% water. Sadly, the amount within the average human body is between 50% and 60%. It is also worth noting that the more muscular the body, the more water it contains. Conversely, the more fat, the less water the body contains as fat cells possess relatively little water.

The body obtains water several different ways. While it may seem obvious, the various ways water enters our bodies is rarely considered. Of course, the most apparent is by simply drinking water. This should be the primary way we receive the majority of our water; however, most people do not drink nearly enough to maintain optimal health. In fact, what we have been told by so-called experts, that everyone should drink 64 fluid ounces (eight – 8 ounces glasses) of water each day, is incorrect. Simply from a common sense perspective, this assertion is ludicrous. How could someone weighing 250 pounds require the same amount of water that a 125 pound person would need? In reality, the 250 pound person needs at least twice as much. Other factors must also be considered. A physically active person will require more water than a sedentary person. To illustrate, a roofer working in Phoenix, AZ. will need considerably more water than a receptionist working in an air conditioned building. The purity of water also plays a role. The more sediments and contaminants contained in water, the greater the burden on the digestive and immune systems thus the higher the body’s demand for pure water. There are many such variables that will influence one’s daily requirement. Everyone’s body type, diet, level of health and lifestyle are different therefore each person needs a certain volume of clean water that is appropriate for them.

To determine your approximate minimum daily water consumption amount, divide your body weight in half. This resulting figure represents the minimum number of fluid ounces the body requires on a daily basis. For example, a person weighing 180 pounds needs at least 90 ounces of water every day. Of course, as previously detailed, this figure may need to be adjusted upwards depending upon one’s diet, level of activity and level of health and the ambient temperature. So how do we account for all the variables in the equation that determines our exact beneficial total? Like so many other issues, particularly those that are health related, there is only one definitive, verifiable method that allows us to obtain accurate, truthful answers to these subjective questions – applied kinesiology. (See Applied Kinesiology – The Ultimate Truth Detector to learn how make an exact determination).

Another beneficial source of water should be natural foods which possess an extremely high percentage of water (up to 95% of total mass) – specifically raw fruits and raw vegetables. Unfortunately, most of us cook our food which removes much of the water content. Additionally, the average American diet includes copious amounts of processed food which contains little or no water. In fact, consuming processed food places a tremendous burden on the digestive system which increases the body’s need for water, making some foods a source of dehydration. Consequently, ideal amounts of water derived from our diet are drastically diminished.

Since the majority of us do not drink enough water or eat enough water dense foods, our bodies are forced to obtain hydration from a less obvious source: absorption through the skin while bathing, showering or swimming. Skin is the largest organ of the body and the more dehydrated a person is, the more water the skin will absorb when immersed in it. It is important to realize that the skin will also absorb everything dissolved in the water. This is true of anything applied to the skin such as creams, lotions, deodorants, soap, hair spray, cosmetics, sanitizers, etc. Therefore, any and all toxins contained in any liquid or spray will be absorbed when applied to the skin to an even greater extent than if they were ingested. When toxins are consumed, at least some of them will be expelled from the body through the digestive and urinary systems. Toxins absorbed through the skin will not be subject to these filtration processes. Keep this fact in mind when considering water purification methods and equipment. An easy rule of thumb to avoid the absorption of contaminants through the skin: do not allow anything on the skin that cannot be eaten. To illustrate, if you are not willing to drink the heavily chlorinated water of the pool or hot tub you are about to use, then do not get into it. If you are not willing to eat the highly toxic moisturizing cream or sunblock, then do not apply it to your skin. Likewise, if you are not willing to drink your tap water, do not shower or bathe in it either.

    I never really considered the implications of the absorption of toxins from water through the skin. The same is true for skincare products and makeup. You hear that things are animal tested safe but, when you think about it, what the hell does that mean? The animal didn’t have an allergic reaction – so what? It doesn’t mean that extremely harmful toxins were not absorbed by the animal that will have devastating long-term effects. Why do we always assume that companies or government are going to do the right thing for us or even know what the right thing is? This article and the others on this site have made me realize that I am slowly but surely being poisoned to death. Thanks for the wake-up call!

    I weight 184 pounds, there is no way I would drink 92 oz of water. I would explode. I go to the gym to sweat off all the excess water. I don’t believe people need this much water.
