The cells in the human body are comprised mostly of water, it is said that from 60% to 80% of a person’s weight is water. Therefore, a person who weighs 60kg contains from 36kg to 48 kg of water, in order to survive, a human being needs this much water. Hydration is simply the percentage of intracellular water held and utilised. The amount of water recycled daily by an adult person’s kidneys is approximately 190 litres. The water that is discharged daily through urine and sweat is around 2.5 litres and must be replaced.
At only 1% dehydration our ability to think clearly and cope with stress begins to diminish.
At around 3% thirst and discomfort is experienced and our ability to perform both physically (Up to 30%) and mentally is significantly impaired.
From +7% dehydration this condition becomes chronic and our genes do not function properly starting to break down.
In excess of 10% dehydration the person can go into a coma, as the body does not have sufficient intracellular fluid to function.
Should our intracellular hydration continue to decrease to between 15% & 20% the effects are likely to be fatal.
Extended periods of dehydration can have a significant effect on our health & our ability to fight off infection & disease. Many studies show that a significant percentage of society are constantly dehydrated, there is no substitute for drinking water! Coffee, tea & most soft drinks can act as diuretics, which all contribute to further dehydration. Is it any wonder that we can feel tired & stressed for no apparent reason? -
