How much water?
A common guideline is about 2 to 3 litres of total fluid a day for adults (8 glasses of 250 ml is 2 litres), and food provides roughly 20% of it. Needs rise with heat, exercise, pregnancy and breastfeeding. Pale yellow urine is a practical sign of good hydration. People with kidney, heart or other medical conditions should follow their doctor's fluid advice.
