Water Intake

Calculate daily water intake.

Explanation

Water is your body's main fuel. This calculator estimates your daily hydration needs based on weight and activity. ### Basic Rule It is often recommended to drink about **0.5 to 1 ounce of water per pound of body weight**. - Or approx 30-35ml per kg. ### Adjustment Factors - **Exercise**: Add 12-20oz (0.5L) per hour of intense workout. - **Heat**: Needs increase significantly in hot weather. - **Diet**: Fruits and vegetables provide about 20% of our water. The rest must be drunk. ### Signs of Dehydration Dark urine, headaches, fatigue, dry skin. If you feel thirsty, you are already slightly dehydrated.

Examples

150lbs sedentary: Approx 75oz (2.2 Liters) per day.
200lbs active: Approx 100-120oz (3-3.5 Liters) per day.
