Water Intake Calculator
Introduction
Water is essential for life, but how much should you really drink every day? While the “8 glasses a day” rule is popular, it may not fit everyone’s needs. Your ideal water intake depends on factors like age, weight, activity level, and even climate. A Water Intake Calculator helps you determine the exact amount your body requires for optimal hydration.
Detailed Explanation
Why Water Intake Matters?

Water plays a vital role in:
- Regulating body temperature.
- Supporting digestion and nutrient absorption.
- Lubricating joints and muscles.
- Improving skin health and energy levels.
The Standard Recommendations

- General guideline: Around 2–3 liters per day for adults.
- Men: ~3.7 liters (about 15 cups).
- Women: ~2.7 liters (about 11 cups).
Factors That Influence Your Water Needs

- Body Weight: Heavier individuals require more fluids.
- Activity Level: Intense workouts increase water loss through sweat.

- Weight
- Age

- Environmental factors
For example:
- Someone weighing 70 kg may need 2.3 – 2.8 liters/day.
