Water Issues: When to Drink Hot and Cold Water
How true is the "eight 8-ounce glasses of water a day" nutritional recommendation?
Arnav Sarkar. It’s a general guideline that I think is not fully accurate. For eg a person living in the North Pole will require much lesser water than someone living in a hot desert. Similarly a man who does hard labor will require a lot more water than a man who works in an airconditioned office. However you may find that beginning with the eight 8 ounce glasses of water a day is a good way to begin, and see from there if you need more. If you are feel thristy, then you are already dehydrated and need to drink more water.
Neelanjana Singh. This dictum is no longer valid as a recommendation. For normal healthy individuals it is advised that water intake such that the color of urine passed is pale yellow. If the color is darker, one needs to drink more water.
