Most people don’t realise that there is a lot of water in the food we eat. One quart (one litre) of water is contained in solid foods that most people consume every day.

Drinking adequate amount of water is a good idea, but overdoing it can have harmful consequences and is unnecessary.
The typical recommended amount of water required is generally stated as eight glasses a day (about 2 litres) but this is largely a rule of thumb. Men should perhaps drink 10 glasses of water a day.

What has been concluded is that THIRST is a remarkably good indicator of when you need to drink. How much water you need is also determined by your diet.

One kilogram of water is equivalent to one litre of volume and so it is easy to calculate. However, thirst is an excellent guide, provided you drink fluids in batches and don’t drink too much at the start. It takes time for the thirst response to catch-up.
