 How much water should you drink every day?Water: How much should you drink every day?

How much water should you drink each day? — 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.

Though 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.

 

Health benefits of water

Water is your body's principal chemical component, comprising, on average, 60 percent of your weight. Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.

Lack of water can lead to dehydration, a condition that occurs when you don't have enough water in your body to carry out normal functions.


Nearly all of the major systems in your body depend on water. How much water do you need?

 

Every day you lose water through your breath, perspiration, urine and bowel movements. For your body to function properly, you must replenish its water supply by consuming beverages and foods that contain water.

A couple of approaches attempt to approximate water needs for the average, healthy adult living in a temperate climate.

 

       Replacement approach. The average urine output for adults is 1.5 liters a day. You lose close to an additional liter of water a day through breathing, sweating and bowel movements. Food usually accounts for 20 percent of your total fluid intake, so if you consume 2 liters of water or other beverages a day (a little more than 8 cups) along with your normal diet, you will typically replace the lost fluids.

  

       Dietary recommendations. The Institute of Medicine advises that men consume roughly 3.0 liters (about 13 cups) of total beverages a day and women consume 2.2 liters (about 9 cups) of total beverages a day.

Even apart from the above approaches, it is generally the case that if you drink enough fluid so that you rarely feel thirsty and produce between one and two liters of colorless or slightly yellow urine a day, your fluid intake is probably adequate.

Multiply your bodyweight by .55-.75 (the higher value applies to people in a warmer climate, this calculator splits the difference at .65). The resulting number is the amount of water you should drink each day in ounces.

Just a thought.

If I substitute some water with coke.
How much water does a can of coke represent.

Now, skip the bad parts with you shouldn't drink sugar and that.
If I drink 1Liter of coke, is that the same as dringing 1Liter of Water?
Or how much less later can my body absorb because it is Coke I'm drinking.
How many % water does Coke represent?
Is 1Liter of Coke the same as drinking 500ml of Water maybe? that would be 50% then.

Is there anyone that can answer such question?

Quoting Martin C:
There's absolutely no way that I need 117oz of water a day. I've asked my Dr, and many others, this question and their answer is always the same - drink when you're thirsty. Don't force yourself to drink water.


Hahaha if you think that is a lot....well idk what is wrong with you. Short of 1 gallon of water i feel thirsty at the end of the day. I lift and run regularly though so maybe you don't. It's not too much though. Hell i know it's bc of the heat, but my bro was putting down 4 gallons just during his officers training.

I have always been told that when you are thirsty you already dehydrated.
