Background Information

Staying hydrated is essential for maintaining good health. The Institute of Medicine (IOM) recommends a base daily water intake of approximately 3.7 liters for men and 2.7 liters for women, including fluids from all beverages and foods. These recommendations can vary based on factors such as body weight, activity level, and climate.

This calculator adjusts your water intake based on your weight (in pounds or kilograms) and additional activity. For example, 30 minutes of physical activity may increase your daily water needs by 0.36 liters. Remember, individual hydration needs can vary, so consult a healthcare provider for personalized advice.
