To calculate your recommended water intake, you can use a general guideline that suggests consuming about 8 cups (64 ounces) of water per day. However, individual water needs can vary based on several factors such as age, sex, weight, physical activity, and climate.

A more accurate approach is to calculate water intake based on your body weight. The National Academies of Sciences, Engineering, and Medicine provide general guidelines suggesting a daily water intake range as follows:

  • For adult men: About 3.7 liters (or about 13 cups) of total water intake per day, including all beverages and foods.
  • For adult women: About 2.7 liters (or about 9 cups) of total water intake per day, including all beverages and foods.

Keep in mind that these recommendations include water from all sources, not just drinking water. Roughly 80% of your total water intake typically comes from beverages, while the remaining 20% comes from the moisture content of food.

It’s important to note that individual water needs can vary. Factors such as physical activity, climate, health conditions, and pregnancy or breastfeeding can increase water requirements. Additionally, certain medications or medical conditions may require adjusting water intake, so it’s always a good idea to consult with a healthcare professional for personalized advice.

Remember, listening to your body’s thirst signals is crucial. If you feel thirsty, it’s a sign that you need to drink more water.
