Water Requirements

Most studies will tell you that the human body needs about 2-3 litres (2000-3000 ml) of water a day. Most people read that figure and forget the rest of the material. Your body is amazingly adaptable. It doesn't have to be obviously fluid water — it can be in coffee, vegetables, fruit, fish, meat; overcooked or oil-fried stuff tends to have less water.

In fact, it's actually possible to not drink any 'water' water for days as long as you have a reasonable wet diet. This isn't necessarily a good thing, but just as most herbivores in arid regions can survive on plants and occasional liquid water, so can you.

Some charlatans out there are touting electrolysed water and stuff like that. It makes no difference except that the processes involved tend to filter out some less-useful components in potable water. The fact is, your body specialises in homoeostasis, and it will compensate within reason.

This all adds up to one more reason why we need to be a little bit more forgiving of our diet and lead a balanced (and more fun) lifestyle. Have a nice wet day!
