According to some of the latest research, unrefined sea salt is indubitably good for your brain and especially so if you spend a lot of time in a hot environment. Your brain appears to be encased in a salty environment and floats in salty cerebral spinal fluid. Salt is constantly being pumped into this fluid. It must be replenished in the diet to contend the optimal brain environment.
The brain is 85 percent water and uses salt for taking acids out of the brain cells. The acidity is a by-product of the power consumed by the nine trillion brain and nerve cells that constantly chatter to one another. The power expenditure produces acidic toxic waste that must be pumped out of the brain to be eliminated. Because high pressure flows to low pressure, just like the weather, salt regulates the pressure so that the acidic wastes are pulled from the cells and pumped to the elimination pipeline. If we are short of salt or water, the acidic toxins build up in the brain and nervous system, creating things like memory problems, cognitive difficulties, dementia and Alzheimer's disease. Your brain functions well on a very narrow pH range. When the brain becomes too acid, the delicate brain cells become damaged and the general brain chatter becomes less and less efficient. This can be caused by dehydration, lack of salt or by a high acid-forming diet.
The human body needs salt to regulate the water pressure inside and face the cells. This water is the highway that transports nutrients into the cells and acidic wastes out of the cells. If this osmosis process in interrupted on a chronic basis, the body becomes toxic and stagnant. The osmosis process uses an "injection pressure" which pushes and pulls nutrient and waste where it needs to be. The drier the body becomes the higher the injection pressure has to be for the osmosis process to work. When the infection pressure becomes out of general range, we call it hypertension. With the right salt and water balance, the push/pull doesn't need to be as great or require so much attempt on the part of the body. This results in the blood pressure returning to general ranges.
We're told not to have salt because of the possibilities of high blood pressure. Of course too much salt is not good either. There must be the right balance. The type and quality of the salt is important, too. Agreeing to Dr. Batmanghelidj in his book The Abc's of Asthma, Allergies and Lupus: Eradicate Asthma, salt is one of the most prominent elements for the body also water. Table salt is not good for you because it's refined of all the other minerals and elements that are good for the body. Unrefined sea salt is a much great for your health.
Today, most bottled water is very acidic and tap water is full of chemicals. Most citizen find tap water distasteful. In some areas of the country, it is very acidic and over time, acidic pH water will conduce to "acidic body diseases" and dehydration. The body does much great on alkaline, ionized water as it allows a neutralizing of metabolic acids so the body stays healthier for longer, or helps to restore condition where it is lacking. You would be wise to build up to drinking half your body weight in ounces of alkaline, ionized water every day. And, of course increase your salt intake.
If you have fuzzy thinking or you can't find your glasses so you can find your car keys, drink more water and sprinkle a itsybitsy unrefined sea salt on your food. You'll feel great for it and maybe you'll find your glasses.
