The "8-glasses" idea? It started from a 1945 recommendation that I forgot to mention most of that water comes from food.

Fruits, vegetables, and soups all contain water. Even coffee and tea count toward your total. Not just plain water from a glass.

If you're not thirsty and you feel fine, there's no need to stress over numbers. Hydration doesn't have to mean chugging gallons daily.

Don't Force It
