Water is the second most common molecule in the universe and the average human body is composed of about 55% water.

It has been said that “the molecular structure of water is the essence of life” by Dr. Albert Szent-Györgi, Nobel laureate.

What is water used for in the body? • A nutrient for every cell.

  • A solvent for minerals, vitamins, amino acids, glucose and lots more.
  • A reactant in the body’s biochemical system.
  • A lubricant around the joints.
  • A carrier that distributes nutrients and other elements throughout the body.
  • A shock absorber that protects vital organs, such as the brain, spinal cord or interior of the eyes, as well as the foetus during pregnancy.
  • A thermo-regulator that helps maintain body temperature and ensure cooling when needed.

The impacts of dehydration Performance – Our ability to concentrate and carry out simple tasks can be affected by mild dehydration. For example, a 2% loss of water results in the following reductions in performance:

  • Concentration 20% • Motor speed 15%
  • Arithmetic ability 10% • Short term memory 13%
  • Efficiency 18%


  • If we have over 2% in water loss our quality of life can be affected in the following:
    • Wound healing. Constipation.
    • Headaches and migraines. • Heartburn.
    • Good oral health. • Insomnia.
    • Sexual performance/libido. • Libido.

Kidney efficiency declines with age, as does thirst perception, and may be particularly severe where there is a history of strokes or cognitive impairment. So it is important to ensure good hydration in the elderl
