8 Cups of Water a Day? Says Who?

Monday Mar 22, 2010

Everybody knows that you are supposed to drink 8 cups of water a day, but nobody seems to know where this disclaimer came from.  It turns out that there is not a specific source, or research done to prove that indeed the correct recommendation for the amount of water that you should drink in one day is 8 cups (64oz.).

The recommendation may differ based on the individual.  The body has an intricate way of regulating body water-through the stimulation of thirst and through regulation of fluid losses through the kidneys.

In hot environments the water consumption should almost double, while in strenuous work or during exercise the fluid intake should triple.  Therefore, it is incorrect to suggest for everyone to drink 8 cups of water per day.  You many need less or more, depending on the circumstances.

The best way to determine the amount of water that you need is to listen to your own body and its thirst mechanism.  You should also monitor your fluid output (e.g. volume of urine).  When exercising, you can weigh yourself before and after and the difference on the scale will be mainly the water that you lost.

You should always learn to listen to your body – it is the best determinant and not just some health claim without a source.

Don’t forget that in hot environments that a healthy salt is needed for proper water regulation. Most people seem to forget about this. Himalayan salt works quite well for this purpose. The regular table salt and sea salts that you see already have a large amount of pollution in them or are highly bleached. Stick with the Himalayan salt for best results.

Thank you for your feedback!

There is much confusion out there about salt, or more accurately electrolytes and exercise. I will try to make it more clear in my next post 🙂
