You are what you drink: Our Body of Water


240314

We’ve always been told water is the building block of life. Water is more than just important to survival, it’s also a very limited resource. “But our planet is covered in water”. Most of us think of planet earth as rich with water and that is true, but not drinkable water. Only 2.59% of the water on earth is drinkable and most of that is locked in ice caps and glaciers. That leaves only about .59% of the earths water from lakes, groundwater and rivers that is drinkable.

What does all that mean for you and I? That means we must take care of our water ways and protect against contamination. We need to drink more water too but think about whats in the water you are drinking and lets discuss just how much of your body uses that water.

Our Body of Water

Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human body is water, the brain is composed of 70% water, and the lungs are nearly 90% water. Lean muscle tissue contains about 75% water by weight, as is the brain; body fat contains 10% water and bone has 22% water. About 83% of our blood is water, which helps digest our food, transport waste, and control body temperature. Each day humans must replace 2.4 litres of water, some through drinking and the rest taken by the body from the foods eaten.

Yes you heard that right, the healthier you are and the leaner you are, the more water your body contains.

According to Dr. Jeffrey Utz, Neuroscience, pediatrics, Allegheny University, different people have different percentages of their bodies made up of  water. Babies have the most, being born at about 78%. By one year of age,  that amount drops to about 65%. In adult men, about 60% of their bodies  are water. However, fat tissue does not have as much water as lean tissue.  In adult women, fat makes up more of the body than men, so they have about  55% of their bodies made of water. Thus:

  • Babies and kids have more water (as a percentage) than adults.
  • Women have less water than men (as a percentage).
  • People with more fatty tissue  have less water than people with less fatty tissue (as a percentage).

There just wouldn’t be any you, or me without the existence of an ample liquid water supply on Earth. The excellent ability of water to dissolve so many substances allows our cells to use valuable nutrients, minerals, and chemicals in biological processes.

Water: The universal solvent

It’s a known fact that water is the universal solvent, carving out chunks of land, canyons and mountains over thousands of years. The erosion of those rocks and soil get into the water and result in dissolved solids, hardness and in populated areas, water contamination.

Responsible Water Treatment

With all that we are learning every day about our water, its more important now than ever before that we learn how to filter our water so that we don’t drink chemicals and by-products from our modern manufacturing processes. Carbon is the best natural resource we have that has an enormous ability to remove chemicals from water through absorption. In the Pelican PC600 alone the surface area of the carbon equals more than 85 football fields.
