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
