Daily Water Intake Calculator – How Much Water Should You Drink?

Staying hydrated is essential for your health, energy levels, and focus. But how much water should you actually drink every day? Our Daily Water Intake Calculator helps you determine the ideal amount of water your body needs based on your weight, activity level, and lifestyle. Read on to discover everything you need to know about hydration!

💧 Why Water Is So Important for Your Body

Regulates body temperature
Improves brain and muscle function
Flushes out toxins
Supports metabolism and digestion
Lubricates joints and keeps skin healthy

🔢 How Our Water Intake Calculator Works

Our calculator considers your:

Body weight (kg or lbs)
Gender
Physical activity level
Environment temperature

General Rule: Multiply your weight in kg by 35 ml.

For example, if you weigh 70 kg → 70 × 35 ml = 2,450 ml or 2.45 liters of water per day.

🏃 Do You Exercise? You Need More Water

For every 30 minutes of physical activity, drink an additional 350–500 ml of water to replace what you lose through sweat.

☕ Do Other Drinks Count?

Yes and no. Herbal teas, milk, and water-rich fruits count toward hydration. However, sugary drinks, energy drinks, or sodas should be limited.

📲 Tips for Tracking Water Intake

Carry a water bottle at all times
Set hourly reminders to drink
Use hydration tracking apps
Drink a glass before every meal
