Separate baseline from exercise

The National Academies values below are Adequate Intakes for total water, which includes food plus beverages. Exercise fluid is shown separately because sweat rate varies widely. Hot conditions can increase needs further.

Do not treat the exercise range as a requirement to force fluids. Sweat rate, heat, body size, pace, and acclimatization matter. Excessive rapid fluid intake can also be dangerous. Kidney, heart, or fluid-balance conditions require individualized guidance.
