Your Brain Knows When It’s Time to Stop Drinking Water


Back in high school, our biology teachers used to say that without food you’ll probably survive for up to 3 weeks.

But without water, you’ll die in 3 days.

Water is important for life.

In fact, that’s one of the only few reasons why we exist today.

It’s essential in almost every living organism on earth.

However, essential as it may be, everything has its limits.

Too much of anything can be bad for your health – even water.

Drinking too much water is bad for you!


There’s a study from the University of Melbourne that’s been gathering a lot of attention lately.

Apparently, they’ve found that even the brain knows subconsciously, to stop drinking water when we’re not thirsty anymore.

The lead researcher, Prof. Derek Denton believes that this gives us a glimpse into human instincts.

And survival behaviour that brought us to where we are today.

Apparently, in their study:

They found that different parts of the brain were involved and activated, depending on why they’re drinking water.

Whether they’re genuinely thirsty, or when the participants were instructed to keep drinking water, even in the absence of thirst.

The brain regions that were activated when the participants were no longer thirsty lead the researchers to believe that this “stop mechanism” was the brain’s ability to identify when we’re drinking too much water.

Stopping us from committing complications to our body from excessive water intake.

What’s really happening, though, is that the brain is protecting itself.


How drinking too much water is bad for you


Drinking in excess creates a salt concentration in the blood, which can result in the swelling of the brain.


The bloodstream


Which proves potentially fatal.

This type of condition is present in some people diagnosed with schizophrenia.

And also in some marathon runners.

However, this type of behaviour demonstrated by the brain might be the start to understand certain other types of behaviours.

And how the brain influences the body to adopt said behaviours.

The researchers believe that this can be potentially used in the same way to understand why certain behavioural and personality disorders exist as well.
