Water Intake Calculator

Staying hydrated is crucial for energy, skin health, and cognitive function. But how much water do you actually need? Our Water Intake Calculator uses your weight and daily exercise levels to provide a personalized recommendation.

Why Hydration Matters

Water makes up about 60% of your body weight and is involved in every single function, from regulating temperature to flushing out toxins.

Activity Adjustment

When you exercise, you lose water through sweat. Our calculator automatically adds about 350ml for every 30 minutes of physical activity.

Hydration Best Practices

  • Drink a glass of water first thing in the morning to rehydrate.
  • Don't wait until you're thirsty—thirst is a late sign of dehydration.
  • Eat water-rich foods like cucumbers, watermelon, and spinach.
