I hope this is the correct place to post this but I hear a lot of different suggestions on water requirements. So much goes into the answer and the old 8 glasses a day isn't true. The body is 60%-80% water depending different parts and requirements are based on weight, climate, altitude, general health, etc. A baseline rule of thumb is 1/2 your body weight. Driving across Dallas in the summer for example, takes 16-20 oz of water to make up for the depletion from the heat and a/c. Too much too fast can overload the kidneys especially during chemo using platinum based protocols. Even the Mayo Clinic suggests 3 liters/day for men, 2.2 for women as a baseline with adjustments for humidity, recent fever, breast feeding, climate, altitude, etc.

Here is a water requirement calculator. Avoid the dehydration especially as we move into warmer months.
