How many ounces of water do you need to drink a day?

Answer 1

There is a debate about how much water a person should drink a day. It has been long recommended that an adult should drink eight 8 ounce glasses per day. That adds up to 64 ounces or a half gallon.

Answer 2

The amount of water you drink per day depends on a number of factors: where you live, how active you are, and your health. The best way to maintain a healthy water intake is to make sure you replace the water that your body loses each day. The average amount of water a person loses in urinating per day is about 1.5 liters. You also lose an additional liter through bowel movements, perspiration, and breathing. Food typically covers 20% of your total water intake so if you drink about 8 cups of additional fluids a day you should typically replace the water that was lost. I hope this was helpful!

How much water should you drink each day? It's a simple question with no easy answers. Studies have produced varying recommendations over the years, but in truth, your water needs depend on many factors, including your health, how active you are and where you live.

Although no single formula fits everyone, knowing more about your body's need for fluids will help you estimate how much water to drink each day.
