WE WILL ONLY KNOW THE WORTH OF WATER WHEN THE WELL IS DRY
Water is truly the essence of life. It makes up about 60% of an adult's body, while a child's body consists of up to 75% of water.
A loss of 3% of total body water will cause fatigue and 10% is seriously life threatening. Depending on climate, diet and body, a human being should drink about 1.5 to 3 l of water every day.
MINERALS ARE IMPORTANT
Water that we drink should include important elements, by the contents of which we recognize its quality.
These namely are the vital elements, such as magnesium, potassium, calcium, sodium, and sulphur.
For example:
● Magnesium is necessary for some enzymes
● Potassium is important for muscle activity and for the transfer of nerve impulses
● Calcium forms a part of the bones and teeth
● Sodium is the main ion of the extracellular fluid and a significant component
● of perspiration.
● Sulphur is essential for some proteins and processes associated
● with energy transfer.
● Drinking water should not contain harmful substances, e.g. nitrates.
WE DRINK FOR HEALTH, EVEN IF WE ARE NOT THIRSTY
It is not necessary to persuade anyone much about the fact that we should drink a lot. Yet, usually, we often drink a little and in single doses and then only when we feel thirst. "This is incorrect. We should drink regularly, even if we are not thirsty. The body needs a sufficiency of water because a large quantity of water is also eliminated from the body. Therefore, it is essential to replenish it continuously.
THE BODY IS MAINLY WATER
The total water quantity depends on age and the body composition. With the majority of adults, water makes up approximately 60% of the body weight and 70% of the active body mass. With aging, the water ratio decreases. If at birth water makes up 75%, in the senior years it's only 55%. Adding that the average daily loss of an adult individual, who has a sedentary job in normal temperature, roughly represents 2,53 liters of fluids. "By breathing we lose about half a liter, in perspiration another half a liter, and a liter and a half with stool and urine. About half a litre of water is present in food another about half a litre of the So-called metabolic water is generated by our metabolism. We need to intake at least a litre and a half to supplement the remaining part. Aging people lose the feeling of thirst. Thus, they could suffer from an excessive loss of body fluid. We advise them to drink in regular time intervals that means according to a daily beverage intake schedule.
The doctors agree that the choice of beverages may be varied, although plain water or mineral water is the best.
