Why Hydration Matters
Water is essential for nearly every bodily function: regulating temperature, transporting nutrients, lubricating joints, and removing waste. Proper hydration supports physical performance, cognitive function, and overall health.
Individual water needs vary based on body size, activity level, climate, and health status. Our calculator provides personalized recommendations based on scientific guidelines.
Base: 30-35 ml per kg of body weight

Tips to Increase Water Intake
- Start Your Day: Drink a glass of water first thing in the morning
- Carry a Bottle: Keep a reusable water bottle with you throughout the day
- Set Reminders: Use phone alerts or apps to prompt regular drinking
- Flavor It: Add lemon, cucumber, or mint if plain water is unappealing
- Eat Water-Rich Foods: Cucumber, watermelon, oranges, and soups contribute to hydration
- Drink Before Meals: A glass before eating aids digestion and reduces overeating
- Track Your Intake: Use our calculator regularly to stay on target
- Adjust for Activity: Add 350-500ml for every 30 minutes of exercise
