The brain is approximately 85 percent water, and brain function—including the nervous system—depends on having abundant access to water.
The average person in the U.S. drinks less than a quart (32 ounces) of water a day. Yet, according to the Mayo Clinic, the average adult loses more than 80 ounces of water every day through sweating, breathing, and eliminating wastes.
If you are drinking less than 80 ounces of water a day, no wonder you have brain fog!
Your brain cannot store water. When your body loses more water than you are replacing, dehydration will kick in and brain function will be affected.
Drinking water and brain function are integrally linked. Lack of water to the brain can cause numerous symptoms, including:
- Difficulty focusing
- Memory loss
- Brain fatigue and fog
- Slow thought-processing
- Headaches
- Sleep issues
- Depression and anxiety
- Balance issues
Water and Brain Energy
Water gives the brain the electrical energy for all brain functions, including thought and memory processes. In fact, brain cells need two times more energy than other cells in the body.
Hydration is also needed for the brain’s production of hormones and neurotransmitters. Nerve transmission requires one-half of all the brain’s energy.
Brain Symptoms of Dehydration
Studies show if your brain drops only two percent in hydration, you may suffer from cognitive issues, short-term memory loss, and problems with focusing.
Dehydration is also a known factor in dementia. Proper hydration may help reduce the risk of Alzheimer’s, Parkinson’s, and Lou Gehrig’s disease.
When the brain is fully hydrated, the exchange of nutrients and toxins will be more efficient—thus ensuring better concentration and mental alertness.
Recommendations for Improved Brain Function
- Start your day off right for optimal brain function. Try drinking 12 to 16 ounces of water as soon as you wake up.
- Always keep a bottle of filtered water near you throughout the day.
- Drink half of your bodyweight in ounces of water. For example, if you weigh 160 lbs, drink 80 oz of water each day.
- Drinking soda, coffee, milk, or juice instead of water does not result in the same level of hydration.
Water provides essential energy to the brain to keep the nerve signals going. It delivers nutrients and removes toxins in the brain. Do all you can to stay mentally sharp and preserve your brain by staying well-hydrated!
