Here’s more proof of the connection between not drinking enough and how well your brain works.
- Water is super important for your mental health. This paper wants to make it clear that we need to think of water as a must-have nutrient for a healthy brain when we do nutrition research.
- This study reviewed a lot of information and found that dehydration, even when it’s mild, makes both simple and complex brain functions worse.
- Big international nutrition websites often downplay how important water is for good nutrition. They also don’t talk about how dehydration impacts your thinking.

Why Water Quality Matters for Cognitive Health
Your brain is about 75% water. Lose just 1% of your body’s water, and you’ll notice your processing speed slows down and your working memory isn’t as good. A big study in 2019, published in Nutrients (Edmonds et al.), looked at 33 different trials. It showed that even mild dehydration consistently made people less alert and worse at short-term recall. Kids and adults over 55 felt these effects the most.
Here’s how it works: less water means less blood plasma, which means less blood flowing to your brain. That cuts down on the oxygen and sugar getting to your brain cells. Plus, even a little dehydration triggers a stress response, releasing cortisol, which makes it harder for your brain to form memories.
Bad water quality makes this problem even bigger. Things like lead (even above 5 ppb), nitrates (above 10 mg/L, the EPA limit), and disinfection byproducts (like THMs above 80 ppb) have all been linked to brain issues in scientific studies. So, just having water isn’t enough – it has to be really clean.
AMPAC USA commercial and industrial reverse osmosis systems solve both problems: getting you enough water and making sure it’s clean. Our systems remove over 99% of heavy metals, chlorine byproducts, and dissolved solids. They typically reduce TDS from 500-2,000 ppm to less than 10 ppm. You’ll find AMPAC systems in schools, company offices, and hospitals. We build models from small 1,500 GPD units for a single spot to massive 100,000+ GPD systems for entire facilities. Every one is NSF/ANSI 58 certified and engineered to ASME standards.
AMPAC USA engineers custom water purification systems for commercial, industrial, and emergency applications — from 500 GPD to multi-million GPD. Trusted by municipalities, military, and industry worldwide.
