Frequently asked questions

How much water should I drink daily?

A common baseline is 30-35 ml per kg of body weight, plus extra for exercise and hot climates. The tool adjusts for both.

Does coffee count toward water intake?

Caffeinated drinks do contribute fluid, but plain water remains the best baseline. This is general guidance, not medical advice.
