Let's Dive into Water: How You Lose It, How You Get It Back

Water is the driving force of all nature.
Leonardo da Vinci, a man of "unquenchable curiosity" and "feverishly inventive imagination"

Every day you lose one of the most important assets in your life: water. Hundreds and hundreds of milliliters of water. Surprisingly, it seems none of us are really worried about it — we're more concerned about time, money and sandwiches.

These are all crucial too, of course, but water is probably the ultimate fortune of all.


What are the Main Ways Your Body loses Water?

  • Evaporation through your skin (sweat) and lungs (breathing) ~ 800-1000 ml.
  • Excretion of harmful substances by the kidneys (urine) ~ 800 ml.
  • Stool ~ 100ml.

These three processes alone cost you 1700 ml of water per day. Let's not forget, those are averages and do not take into account your physique or climate conditions, which can affect these amounts. Apart from natural reasons your body loses water there are some additional ones, usually related to illnesses: diarrhea and vomiting, fever, excessive sweating and increased urination. And, of course, there are products that treacherously drain you out of water:

  • Coffee
  • Alcohol
  • Sugary Drinks
  • Fried Foods
  • Cured Meats
  • Soy Sauce
  • Bouillon Cubes (ugh, we hope you didn't use those anyway)
  • Popcorn
  • White Asparagus

What happens when your body is running out of water (i.e. dehydrated)? For instance, the amount of blood in the body is reduced, which makes your heart work harder so it still can deliver oxygen-bearing cells to your muscles. Being dehydrated also influences your mental functions as well as the ability to regulate body temperature. It is a known fact that losing even 1 percent of your body weight in water has a major impact on your physical performance and makes you feel tired.

So How Does Your Body Replenish It?

  • You get at least 600-700 ml of water with different drinks per day.
  • You acquire approximately 750ml of water through food (practically all products contain it).
  • Some water is produced as a result of metabolic processes ~ 320 ml.

This totals about 1750-1800 ml — about the same as you've lost, so why bother drinking more water, right? Wrong. Since your body needs water to transport oxygen and nutritional chemicals to the organs (especially the brain) through blood (as well as to moisturize mucus membranes and to regulate its temperature), when your water balance is down by just 2%, there is a noticeable decrease in mental skills like short-term memory and attention span. In other words...

You Need More Water! But How Much Exactly?

This is where the water balance comes in. Water balance, as you may have already guessed, is the ration of water you consume to the water you lose. You need to be conscious of your body's water balance, because there is such thing as too much water: an overabundance can lead to such conditions as edema and arterial hypertension.

There are several ways to control your water balance. You can consult a scientific table, which tells you the approximate amount of water you lose and need based on your age, sex, height, weight and level of physical activity. But let's be honest, you don't even have time for a cup of coffee at work — how are you going to spend time immersing yourself in complex tables? Yeah, we thought so.

There is also a special formula for daily water balance, which requires you to know such variables as body temperature coefficient, the amount of metabolic water, and daily urine (yeah, seriously). Once you figure all of them out, you can easily calculate your water balance... on a daily basis. Yes, you will have to do it each and every day. Probably with a calculator. We all know that is not gonna happen.

The Healbe GoBe Body Manager helps you keep track of your water balance on a daily basis without you having to worry about it. It can actually 'see' both the water in the food you eat and the liquids that contain carbs (i.e. coke, tea with sugar, juices, etc.) using a special patented algorithm based on tissue impedance, which estimates the amount of water inside and outside of your cells.

Then, using your age, height, weight, etc., the Body Manager determines your personal required daily water intake in milliliters (or Ounces), keeping in mind both the water you lose due to physical performance, and your dietary regime. These two factors heavily influence your daily water intake. For instance, in the morning, you may see that today you need 2.5 liters of water. After a long run, this amount may easily change to 3 liters — and the Body Manager will tell you that, because it constantly registers and adjusts your daily water intake, not just once or twice a day. Bear in mind, however, that not all water you get is absorbed by the body — some of it goes straight to the bladder.

Unfortunately, the Body Manager is not yet able to see the clear water (with no carbs) you actually drink, and this is why we have provided simple “cups” icons in your Healbe App: you just tap the icon of a cup, letting the GoBe Body Manager know that you have drank some clear water, so that it can subtract 200 ml/ 8 Oz. (average drinking cup volume) from your daily required intake. No more worries during the day: you get your things done, while GoBe takes care of your water balance.
