Did you know that your body is mostly water?

You need to be properly hydrated to live and be healthy. Sadly, a large proportion of the population is dehydrated, and they are suffering for it.

Research shows that dehydration makes you age faster, weakens your joints, contributes to disc and spinal problems and can cause depression (our brain is about 77% water).

Think of what you need to survive, really just survive. Food? Water? Air? Facebook? Naturally, I’m going to concentrate on water here. 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.

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. Fat men also have less water (as a percentage) than thin men. Thus:

  • Babies and kids have more water (as a percentage) than adults.
  • Women have less water than men (as a percentage).
  • Fat people have less water than thin people (as a percentage).*

Other conditions linked to dehydration are high blood pressure (your blood is thicker so your heart has to work harder to pump it), constipation, asthma, allergies and obesity. These (and many other) problems have cleared up by rehydration. It usually takes about two weeks to rehydrate yourself.

How do you become dehydrated? It’s easy if you drink coffee, tea, soda and juices instead of water when you are thirsty. Those drinks may quench your thirst, but they do not rehydrate you.

It’s best to drink water at room temperature or warmer.
