Common Water Intake Questions Answered
How do I know if I'm drinking enough water?
Check your urine color - pale yellow indicates good hydration. Dark yellow suggests you need more water. Also monitor energy levels and thirst.

When should I drink more water?
Increase intake during exercise, hot weather, illness (especially fever), pregnancy, and breastfeeding. Our calculator adjusts for these factors automatically.
