Daily Water Intake Calculator
How much water should I drink daily?
A general rule is to drink about 30–35 ml of water per kilogram of body weight. This varies based on your activity level and climate.
Does physical activity increase my water needs?
Yes. Exercise, sweating, and hot environments increase fluid loss, so you’ll need to drink more water to stay hydrated.
Can I count tea, coffee, or juice toward my water intake?
While these contribute to hydration, plain water is the healthiest and most effective way to stay hydrated.
What happens if I don’t drink enough water?
Dehydration can cause fatigue, headaches, dizziness, and poor concentration. Chronic dehydration may affect kidney function and overall health.
