Your recommended water intake is estimated based on your weight, age, and gender. On average, a person should drink approximately 35 milliliters of water per kilogram of body weight. This is adjusted for gender and age to ensure optimal hydration.

- For males, the recommended intake is based on 35 mL per kilogram of body weight.

- For females, the recommended intake is based on 31 mL per kilogram of body weight.

For children under 18 years old, the intake is reduced by 0.5 liters, and for older adults over 65 years old, the intake is increased by 0.5 liters.
