You've probably heard that around 60% of the human body is made up of water and because of that, it's important to drink enough of it. But, what does "enough" really mean?

Read on to find out!

Scientifically Proven Benefits of Drinking Enough Water 

1. It Helps You Lose Weight

Many studies show a positive correlation between increased water consumption and weight loss [1]. Possible reasons are:
1. Water helps take up space in the stomach, causing a feeling of fullness and reducing hunger
2. Often feeling hungry is simply due to a state of dehydration
3. Our body needs water in order to burn fat

2. It reduces the likelihood of headaches

Research shows that one of the most common signs of dehydration is headaches [2].

Drinking enough water and staying optimally hydrated can significantly reduce the likelihood of headaches caused by dehydration.

3. It helps you be more productive 

Studies have shown that even mild dehydration of 1% - 2% can impact cognitive performance. No wonder, given that approximately 73% of the brain is made up of water [3].

It's important to drink enough water to improve cognitive performance and critical thinking skills so you can perform tasks more efficiently.

How much water is “enough” for you?


In the past, the general recommendation on the amount of water to drink followed the 8x8 rule, i.e. drink eight 8-ounce glasses of water per day, which equals about 2 liters of water.

But considering our differences in height, weight, gender and lifestyle, experts agree there is no magic number that fits all. A long-distance runner, for example, will lose fluids more quickly than someone who primarily practices yoga and meditation.

It is also important to note that the amount of water you drink will vary on different days depending on the activities you do. For example, on days when you go for a walk, or any other form of physical activity, you may need to drink more water to make up for the water lost through sweat [4].

In fact, knowing what it's like to drink "enough" water every day can be a little tricky, but there's a way out...


Here is how REBO can help you


Our hydration experts have developed an algorithm that identifies your daily hydration goal based on your unique features.

Thanks to this algorithm, the REBO App creates a personalized hydration plan based on your gender, age, height, weight and lifestyle.

Additionally, the REBO App syncs with other health apps, such as Apple Health, Google Fit and Adidas Runtastic, to measure your daily physical activity and adjust your hydration plan accordingly. For example, if you decide to go for a run, the REBO app will recognize this and encourage you to drink more water.

Finally, with REBO Smart and REBO Go you can monitor exactly how much water you drink and stay away from the effects of dehydration thanks to reminders.
