About this tool
This suggests a daily water intake from your weight, using roughly 35 millilitres per kilogram, plus a little more for exercise. It is a general guideline, not a strict rule or medical advice. Your needs change with climate, diet, and health, and food and other drinks count toward your fluids. Thirst is a good everyday guide. Ask a healthcare professional about your own needs.
