We need to stay hydrated.  Your brain needs to be properly hydrated to function, but only water is hydrating.  Without water your brain wouldn’t function and you wouldn’t live. 

Your brain tissues and cells live in water.  It’s water that contains the foods that your brain cells feed on.  It’s water that allows the cell enzymes in your brain to function.  It’s water that keeps the tissues and cells flexible.  It’s water that removes waste and toxins from your brain, and it’s water that protects the brain from banging into your hard, bony, spiked skull.  It’s water that keeps you alive.

You get water from the water you drink as well as the foods that you eat and drink.  Fruits and vegetables are the foods that contain the most water.  Low fat or skimmed milk have a high water content as does vegetable juice.  Cocoa or hot chocolate made with water or milk are mostly water.  

Pure water, moves into your blood the quickest, since it doesn’t have be filtered.  The water in milk, vegetable juice, coco, etc. or water with flavoring, has to be filtered so that the ingredients enter the blood properly.  Water that has to be extracted from the foods you eat has to be filtered before it can enter your blood.   

The question always comes up as to How much water is enough. You are always carrying a water tank and gauge with you.  That water tank and gauge tells you when you’re properly hydrated and when you need more water in your system for proper hydration. 

The water tank that you carry is your urine.  The gauge is the color of your urine.  To be properly hydrated your urine should be a light straw color.  The darker the color the less hydrated you are.

The Brain-body system is constantly using water.  That suggests that the color of your urine will be changing throughout the day based on what you’re doing, eating and drinking.  

Physical activity as well as brain activity will use water.  Temperature and humidity will affect your hydration.  Having an infection in your system or taking medicine will affect the color of your urine and your level of hydration. If you pay attention to the color of your urine it will give you a strong indicator of your level of hydration and whether you need to be drinking more water.
