Water is an important structural component of skin cartilage,
tissues and organs. For human beings, every part of the body is
dependent on water. Our body comprises about 75% water: the brain has
85%, blood is 90%, muscles are 75%, kidney is 82% and bones are 22%
water. The functions of our glands and organs will eventually
deteriorate if they are not nourished with good, clean water.
The average adult loses about 2.5 litres water daily through
perspiration, breathing and elimination. Symptoms of the body's
deterioration begins to appear when the body loses 5% of its total
water volume. In a healthy adult, this is seen as fatigue and general
discomfort, whereas for an infant, it can be dehydrating. In an elderly
person, a 5% water loss causes the body chemistry to become abnormal,
especially if the percentage of electrolytes is overbalanced with
sodium.One can usually see symptoms of aging, such as wrinkles,
lethargy and even disorientation. Continuous water loss over time will
speed up aging as well as increase risks of diseases.
If your body is not sufficiently hydrated, the cells will draw water
from your bloodstream, which will make your heart work harder. At the
same time, the kidneys cannot purify blood effectively. When this
happens, some of the kidney's workload is passed on to the liver and
other organs, which may cause them to be severely stressed.
Additionally, you may develop a number of minor health conditions such
as constipation, dry and itchy skin, acne, nosebleeds, urinary tract
infection, coughs, sneezing, sinus pressure, and headaches.
So, how much water is enough for you? The minimum amount of water
you need depends on your body weight. A more accurate calculation, is
to drink an ounce of water for every two pounds of body weight.
