The Science Behind Brain Fog

Water is life.

Pure water is the world's first and foremost medicine. - Slovakian proverb

Water is indispensable to the operation of each brain cell. And sometimes, getting enough can be a challenge.

Your brain is 80% water, and it's important to maintain stability. Even a small "drop-off" has consequences.

 

A 2018 study[1] found a 2% loss in hydration causes a measurable loss in focus and cognition. Two percent isn't that much. We may not even feel thirsty. If dehydration hits 5%, your loss of focus and concentration hits 35%.

Another study[2] found even one percent produces deficits.

All this can lead to mid-day grumpiness.

Here's one thing you can do right now:

   Drink one cup of water with each meal.

In no time your brain links meal and water. It becomes a habit. Remember, brains get good at what they do. Neuroplasticity!

( And, of course, sip water often all day. It does add up.)
