It's been very hot lately and I always crave for ice cold water to quench my thirst. I prefer water over soda, I only drink soda occasionally when I feel like it or when in a party. Here are some useful facts about water that is worth sharing about.

Water makes up 83% of the blood and acts as a transport system, delivering nutrients to the brain and eliminating toxins.
Your brain needs to be fully hydrated so that the circuitry works well and it functions at optimum levels. Water is essential for concentration and mental alertness.
Studies have shown that most people are permanently partially dehydrated. This means that their brain is working considerably below its capacity and potential.
A study by Trevor Brocklebank at Leeds University in the UK discovered that schoolchildren with the best results in class were those who drank up to eight glasses of water a day. (source: Bill Lucas, Power Up Your Mind, 2001)
Therefore, you should drink at least 2 litres of water every day.
