Water makes up more than two thirds of the weight of the human body and without it, humans would die in a few days. The human brain is made up of 95% water, blood 82% and lungs 90%. A mere 2% drop in our body water supply can trigger signs of dehydration: fuzzy short-term memory, trouble with basic math, and difficulty focusing.

Mild dehydration is also one of the most common causes of daytime fatigue. An estimated seventy-five percent of Europe's population has mild, chronic dehydration; pretty scary statistic for developed countries, where water is easily available.

Water is important to the mechanics of the human body. In fact, all the cell and organ functions made up in our entire anatomy and physiology depend on water for their functioning.

- Water serves as a lubricant

- Water regulates the body temperature, as the cooling and heating is distributed through perspiration.

- Water is the best detoxifying agent.

- Regulates metabolism

In addition to the daily maintenance of our bodies, water also plays a key role in the prevention of diseases; bladder cancer risk is reduced as well. Drinking eight glasses of water daily can decrease the risk of colon cancer by 45%, bladder cancer.
