Calculate How Much Water To Drink In A Day

It is important to drink the right amount for your weight.

The simple formula is your weight in pounds ÷ 2 = water amount in ounces (oz). For example, if you weigh 190 pounds ÷ 2 = 80 oz (2.2 litres) per day.

Calculate Your Daily Water Intake

Here is the step by step process to do this:

1. Find out your weight.

The old adage was that you should drink 8 glasses of water a day but experts are beginning to give different advice. Experts now advise that each person should drink the right amount of water for their body weight.

This means that you first need to know how much you weigh. Doing this will help you determine the right amount of water intake for your body.

Of course this makes sense on even the most basic level right? Someone who weighs 100 pounds will have different hydration needs to someone who weighs 250 pounds. So in order to properly determine the right amount of water you must know your exact weight. Once you know your weight then do the following:

2. Exact daily water intake calculation… in 2 easy steps:

Once you know how much you weigh, you only have 2 steps to calculate your exact daily water intake.

  1. Divide your weight in half and convert it into pounds.
  2. Divide that figure (in pounds) by half to get your daily water intake in ounces.

For example, your weight is 100 pounds, divide that by 2, which gives you 50 ounces (oz). This means you should be drinking 50 oz (or 1.42 liters) each day.

3. What About Your Level Of Physical Activity?

The calculation above is only good if you are not physically exerting yourself that day. It is important to remember that your hydration needs will change if you’re very physically active.Heart Water

This is very important because working out causes you to sweat. Sweat essentially means your body is expelling water and you lose fluids. That lost water will need to be replaced in some way.

It is estimated that you need about 12 oz of water for every 30 minutes of exercise you do. Think about it. This estimation means that you need an extra 24 oz of water for every hour of exercise.

If you are using the simple calculation used in this post to work out how much water you need to drink a day remember work outs.

You must compensate for the water that you lose when you are physically active. You should also keep an eye on and know the signs of dehydration to avoid getting sick.

How To Drink Enough Water

Now it may seem both impossible and undesirable to drink 50 ounces of water in one day.

AquaTruHowever, it is not as hard as you think. Simply adding an extra glass to your usual daily routine could get you up to your recommended water intake in no time.

For instance, each time you do something that is part of your normal daily habitual routine, drink a glass of water. I also like the idea of opting for water every time you reach for caffeinated beverages instead.

My favourite little hack is to drink a glass of water when I wake up, before a meal and after I brush my teeth. Eventually, you will begin to feel thirsty during these times and create a habit that lasts and makes a difference.

Another clever little hack is to buy a special container that will contain the exact amount of water that you need. Then simply take water from this container to keep track of your progress. There is also a type of water bottle on the market now that has motivational quotes at each cup or so of water, to motivate you to up your fluid intake and stay on track.
