Against 8 Glasses of Water a Day

There are posts going around the internet right now as research has not supported the claim that one should drink 8 glasses of water a day.

For example, Dr. Valtin stated in his 2002 review the following:

No scientific studies were found in support of 8 x 8 [glasses of water a day]. Rather, surveys of food and fluid intake on thousands of adults of both genders, analyses of which have been published in peer-reviewed journals, strongly suggest that such large amounts are not needed because the surveyed persons were presumably healthy and certainly not overtly ill.

As most traditional health systems are about understanding the patient a one-size fits all maxim does not bode well.  In regards to 8 glasses of water a day, one must be careful too as too much water can inhibit digestion and if the water is cold the detriment to digestion is pronounced.  Additionally, it’s ideal to consume broths and stocks and herbal teas and certain fermented beverages (this is not a reference to alcohol believe it or not) for their additional nutritional value and support to the digestive process.

As often is the case, listen to your body when it comes to thirst.
