Drink water much, good for health

Many of us drink water, but not the mineral water that doctor ask us to, but another water (most of it soda), and why doctors advise us to drink water, why do we have to drink water at least 8 glasses a day?
This is the scientific explanation, and this is a fact!
Approximately 80% of the human body consists of water. In fact, there are some parts of our bodies that have water levels above 80%. The two most important organs with water content above 80% are: Brain and Blood.

The brain has a component of water by 90%, while the water component of blood has 95%. Ration drinking is a normal human being at least 2 liters a day or 8 glasses a day. The number of the above must be added if you are a smoker.
That much water is needed to replace the fluid that comes out of our body through urine, sweat, respiration, and secretion. So what happens if we consume less than 2 liters a day? Of course the body will balance itself. How? By the way "suck" water from the body's own components. From the brain? Not until that much! But from the nearest source: blood.

Blood is sucked water will be thick. As a result of this blood coagulation, the trip will be less smooth than the dilute. As it passed the kidney (which remove toxins from the blood) kidneys will work extra hard to filter blood. And because the kidneys filter the fine, not infrequently a thick blood can cause kidney glomerulus perobekan on. As a result, your urine reddish, signs began leaking kidneys filter. If allowed to continue, you may someday have to spend a lot of money to wash the blood.

As thick blood flowing through the brain, somewhat hampered travel. The brain is no longer "thin", and because brain cells are the most wasteful consumption of food and oxygen, the slow blood flow can cause brain cells to die quickly or are not functioning properly.

If this disease coupled with "heart" (which also works if the added weight of the blood thickens), then the stroke could be more soon to come. Now living you choose: to "investment" by drinking at least 8 glasses a day, or "pay interest" through the kidneypain or stroke. You choose!
