It’s no nutritional secret that we need sufficient water daily and most of us know we ‘should drink more’, but why?

Over 75% of the human body is water, it bathes each cell and facilitates the exchange of minerals, enzymes, nutrients and waste material in and out of the cell. This means that water has a critical role for every function in the body and increasing your intake to a safe and recommended level of 2 litres daily for an adult (child volume varies on age, gender and activity) can have a host of positive effects including:

  • Improved digestion – water is needed to make stomach acid and digestive enzymes to fully digest your food.
  • Decreased tendency to constipation – not drinking enough fluid leads your body to reabsorb water from your colon…leading to dry hard faeces and constipation.
  • Relieves fatigue – this is often the first sign of dehydration…not thirst. Low fluid levels can alter your blood volume and make your heart and other organs work harder, leading to fatigue.
  • Supports mood balance and mental clarity – even a one to two percent drop in hydration levels can negatively affect your mood and your ability to think clearly.
  • Supports the reduction of headaches and migraines – studies show an overall decrease in the frequency and intensity of some headaches and migraines when optimal hydration is reached.

The quality of your water is also important.  As a ‘purer’ water option for drinking and cooking many people choose bottled mineral or spring water, this can be expensive, cumbersome to store and is a drain on resources with packaging and transportation. A water filter can be a cost effective and environmentally supportive long term solution.


The average adult human body is 50-65 percent water.
