Essential Functions of Water

Water Part 1

Did you know the human body is made up of approximately 60% water?

The brain is made up of 75% water and our blood is 83%. We are continually losing water over the day through urine, sweat and in our breath as vapour.

This water has to be replaced, as the body cannot store water. In fact, the human body can last weeks without food but only days without water; water is absolutely essential to life.

Essential Functions of Water:

  • Acts as a delivery system, taking nutrients to cells and removing waste
  • Forms the base of many bodily fluids such as blood and saliva
  • Helps regulate body temperature
  • Forms fluid surrounding joints
  • Needed for digestion, softening and dissolving food components
  • Essential for normal bowel movements and preventing constipation
  • Keeps skin hydrated

Dehydration can result from not drinking enough, from losing too much fluid through sweat.

For example, in hot temperatures or when exercising for long periods, or from vomiting and diarrhoea when we are unwell.

The cells of the body cannot function properly without water.

A drop in our body’s water levels can trigger the following symptoms of dehydration:

  • Headaches
  • Fatigue
  • Dry skin
  • Mood changes and slow responses
  • Lightheaded or dizziness
  • Dry mouth and throat
  • Loss of concentration
  • Dry and cracked lips

Furthermore, if the body is continually dehydrated there is a risk of more serious problems… These include constipation, urinary tract infections and kidney stones. The simplest way to tell if you are getting enough is to check the colour of your urine.  It should be light in colour, dark urine is a sure sign you need to drink up.


Energy and Exercise Performance:

Dehydration is one for the fastest routes to low energy, even a drop in body water of just 1 or 2 per cent can result in your energy levels dropping significantly.

As well as physical energy, its mental energy too. The ability to think clearly, mood, concentration and memory all suffer when we are dehydrated. If you feel your energy or concentration is flagging, a glass of water may be all you need to perk up.

Water is also essential for exercise performance, as your muscles cannot function properly without adequate fluids.
