Water balance: Understanding GoBe’s Hydration data

The Importance of Hydration

Did you know that water makes up 2/3 of your body? Water, and staying hydrated, is essential for you body to function normally. For example, water plays a key role in maintaining a normal body temperature, ensuring normal blood circulation, regulating digestive processes, transporting oxygen to organs and cells, and much more.

Staying hydrated can also help you lose weight! Dehydrated tissues and cells inhibit protein production and in turn, the formation of new muscle and the process of burning calories.

Dehydration has several noticeable physiological impacts as well, including fatigue, headaches, poor skin elasticity and decreased joint mobility.

How GoBe Helps You Stay Hydrated

When you first put on your GoBe, it will immediately start collecting data to analyze your body’s “normal” hydration level unique to YOU. This learning process can take GoBe anywhere from two days to two weeks of consistently wearing the device.

In YEAR, Healbe studied the skin tissue underneath the devices sensors on the user’s wrist. We found that your individual level of hydration directly correlates to the amount of fluid in your cells. This means hydration is not dependent on how much liquid you consume, it’s dependent on how much of that liquid your cells retain.

Using the bioimpedance sensor and patented Healbe FLOW Technology, GoBe calculates your current level of hydration and compares it to your learned “normal” level of hydration.

Hydration Level Low

When your GoBe device vibrates and reads “DRINK,” this is a reminder to drink water because your hydration level is below normal. This reminder comes long before your hydration levels could cause any potential health risk. GoBe’s objective is to keep you consistently hydrated and prevent you from reaching critical levels of dehydration.

That said, do not worry if your GoBe shows a reduced hydration level - even if it lasts a relatively long period of time - as long as you are drinking fluids in any form throughout the day.

Hydration Level Accuracy

The accuracy of your hydration level reading is dependent on many factors. To ensure the greatest accuracy, you must wear the device constantly according to the user manual (taking it off only to charge), ensure constant contact of the device sensors with the skin by adjusting the strap and clean the device according to the care and maintenance instructions.

Additionally, after bathing, showering, washing hands, swimming in freshwater or sweating, it’s best to wipe dry the sensors on the bottom of the device as well as the skin on your wrist the sensors come in contact with to be sure the moisture does not interfere with GoBe’s readings.

PLEASE NOTE: If you reset your GoBe to factory settings, update the firmware, put the device back on your wrist or turn the device back on after 9 PM, hydration data will not be reported in the mobile app or web dashboard until between 6AM and 8AM the following day.

How Does My Body Digest Water?

As mentioned above, your hydration level is not based on how much water you consume, but instead on how much water your body retains.

When you drink a glass of water, the water is in your stomach for approximately 10 minutes. From there, it moves through the intestines, a large amount being absorbed in the large intestine.

If you drink water on an empty stomach, before or in between meals, the movement of water through your digestive track would take about 20 minutes. If you have food in your stomach or intestines, the time it takes for your body to process the liquid you drink increases.

Every day, your body receives (on average) about 2.5 liters of water from drinking water, eating water-rich foods (fruits, vegetables, soup, etc.) and absorbing water released during intracellular metabolic processes (a.k.a. metabolic water - which equates to about 400 ml per day).

The way your body digests water and the rate at which it is absorbed during the digestion process can be impacted by medications that affect your water-salt metabolism and hydration levels. Diuretic medications (to increase urine flow) will result in a decreased hydration level detected by your GoBe and antidiuretic medications (to decrease urine flow) will result in an increased hydration level detected by the device.

GoBe adjusts to YOUR body’s normal level of hydration because just like the way your body absorbs nutrients from food, the way your body absorbs water is unique to you.

Also, it’s important to remember that your body absorbs water differently under different conditions. For example, if you drink two cups of water at once after a long period of physical activity, your body will absorb less of that water than if you periodically hydrating during your activity session.

Finally, the method of hydration affects how your body absorbs water as well. Mineral water and isotonic drinks are absorbed quickly, whereas sugary soda and strong alcohol contribute to the loss of body fluids.

Notification of "DRINK"

When GoBe detects a decreased hydration level, it will remind you to rehydrate by vibrating and displaying the message “DRINK” on your device screen. GoBe’s hydration reminders are based the analysis of several parameters including metabolism, activity level and personal data shared in your profile.

You have the option to set a time interval during which GoBE will remind you to rehydrate to ensure it will not disturb you during meetings and activities. The notifications are automatically disabled overnight.

Hydration Level Indicators

You can also view your hydration level in the Healbe GoBe app. Here you will see  four levels of hydration:

* NORM - your body’s hydration level is normal

* LOW -  your body’s hydration level is below normal

* N / A - no hydration data available due to lack of contact of the sensors with the skin

* CALC - GoBe is calculating your current hydration level

Each time you put the GoBe back on your wrist, it can take 30 minutes to two hours to calculate your hydration level. Inconsistent contact between the device sensors and your skin will increase the detection period.
