Chronic dehydration has some serious negative effects on your brain and body.

Initial symptoms are hard to notice and can easily be attributed to just feeling off. If you’ve been dehydrated too long, dehydration can feel normal.

Losing as little as 2% of fluids can significantly impair physical and mental performance. When you exercise, you lose 6-10%.

At universities in East London and Westminster, students who hydrated while taking an exam improved their scores by 5% over their dried-out classmates.

Staying hydrated isn’t complicated, but it’s not as easy as simply drinking water.

We don’t need to tell you drinking water is important. Our bodies are mostly made up of the stuff.

You need water to make sure every cell in your body is functioning at its best.

The good news: there’s water in everything you drink--even milk! But, you need enough electrolytes to make the most of the water you’re already drinking.

Electrolytes--specifically sodium, chloride and potassium--are vital for hydration.

They play a crucial role in delivering water to your body’s cells. If you’re not regularly getting enough of them in your diet, the water you’re drinking isn’t efficiently used, risking your chance of dehydration.

You need electrolytes to balance your body’s fluids, maintain pH levels in your blood and regulate your nervous system. When your fluids aren’t balanced, you’re either losing more water than your body can take in (dehydration) or consuming more water than your body can get rid of (hypervolemia). Both are bad.

In almost all cases of dehydration, low levels of sodium and potassium are present.
