HEALTH: How Much Water Should I Drink?

We are all roughly two-thirds water. It makes up about three-quarters of our lean body mass, about 10% of our fat, and in terms of the amount of time we could live without consuming it, water is the most essential of our nutrients. But exactly how much water should we be taking in each day?

You might expect science to have provided a reliable answer to such a question – water is a fundamental constituent of life, after all.

But with the highly evolved ability of the human body to regulate water so exquisitely – and with lots of individual variability in the optimum intake – there is no definitive answer for the amount of water one person or another should get each day.

In fact, the best guidance is simply to follow the natural call of the body when more fluid is needed: just follow your thirst.

Yet the question of amount persists, and there is misinformation in abundance. Vested interests come up with highly questionable ideas about how we should all be drinking more water. Even well-respected sources cite daily intake amounts that lack good scientific evidence to support them.
