What is the Ideal Daily Water Intake?

What is the Ideal Daily Water Intake?

The ideal daily water intake is influenced by several factors, such as your body weight, activity level, climate, and unique physiological conditions (e.g., pregnancy). A common guideline is to drink 0.033 liters of water per kg of body weight or roughly half an ounce of water per pound of body weight.

However, factors like exercise and temperature can significantly alter your water needs. For example:

  • Exercise: When you work out, you lose fluids through sweat. For every 30 minutes of exercise, it is recommended to add 0.355 liters (12 ounces) to your daily intake. Learn more about optimizing your workouts with our 1 Rep Max Calculator.

  • Climate: In hot or humid climates, your body loses more water through sweating, and your water requirement increases by approximately 25%.

  • Pregnancy and Breastfeeding: If you are pregnant or breastfeeding, your daily water intake should increase to support both your body and the baby's health.

Our calculator takes all these factors into account to provide you with an accurate estimate of how much water you should drink.

  • Pregnancy/Breastfeeding Adjustment: Additional water intake to support pregnancy or breastfeeding needs.
