• ions that move to the cathode (cations) are positively charged<br />
• ions that move to the anode (anions) are negatively charged<br />
For example, your body fluids -- blood, plasma, interstitial fluid (fluid between cells) -- are like<br />
seawater and have a high concentration of sodium chloride (table salt, or NaCl). The electrolytes<br />
in sodium chloride are:<br />
• sodium ion (Na+) - cation<br />
• chloride ion (Cl-) - anion<br />
As for your body, the major electrolytes are as follows:<br />
• sodium (Na+)<br />
• potassium (K+)<br />
• chloride (Cl-)<br />
• calcium (Ca2+)<br />
• magnesium (Mg2+)<br />
• bicarbonate (HCO3-)<br />
• phosphate (PO42-)<br />
• sulfate (SO42-)<br />
Electrolytes are important because they are what your cells (especially nerve, heart, muscle)<br />
use to maintain voltages across their cell membranes and to carry electrical impulses (nerve<br />
impulses, muscle contractions) across themselves and to other cells. Your kidneys work to keep<br />
the electrolyte concentrations in your blood constant despite changes in your body. For example,<br />
when you exercise heavily, you lose electrolytes in your sweat, particularly sodium, magnesium<br />
and potassium. These electrolytes must be replaced to keep the electrolyte concentrations of<br />
your body fluids constant.<br />
So, many sports drinks have sodium chloride or potassium chloride added to them. They also have<br />
sugar and flavorings to provide your body with extra energy and to make the drink taste better.<br />
They most always have the wrong balance of electrolytes and thus these sport drinks create more<br />
damage. Avoid them. You can make a better one with using 100% fruit juice rich in natural <strong>Fructose</strong><br />
as one part juice to two parts good water.<br />
Another example where electrolyte drinks are important is when infants/children have chronic<br />
vomiting or diarrhea, perhaps due to intestinal flu viruses. When children vomit or have diarrhea,<br />
they lose electrolytes. Again, these electrolytes and the fluids must be replaced to prevent<br />
dehydration and seizures. Therefore, drinks such as Pedialyte have sodium and potassium in them<br />
like the sports drinks do. However, pediatricians do not recommend giving sports drinks to a sick<br />
child! Sports drinks have much higher sugar concentrations than Pedialyte and the high sugar is<br />
not a proper treatment.<br />
Electrolytes are the smallest of chemicals that allow the body to work. Electrolytes such as sodium,<br />
potassium, and others are critical in allowing cells to function. They generate electricity, contract<br />
muscles, move water and fluids within the body, and participate in myriad other activities.<br />
The concentration of electrolytes in the body is controlled by a variety of hormones, most of<br />
which are manufactured in the kidney and the adrenal glands. Sensors in specialized kidney cells<br />
monitor the amount of sodium, potassium, and water in the bloodstream. The body functions in a<br />
very narrow range of normal, and it is hormones like renin (made in the kidney), angiotensin (from<br />
the lung, brain and heart), aldosterone (from the adrenal gland), and antidiuretic hormone (from<br />
the pituitary) that keep the electrolyte balance within those limits.<br />
Keeping electrolyte concentrations in balance also includes stimulating the thirst mechanism when<br />
the body gets dehydrated. The thirst mechanism weakens somewhere between the age of 15 to<br />
25. The hypothalamus where the thirst mechanism is most focused burns out and our bodies do<br />
not properly provide the thirst signal. So most of us live in a sub-clinical state of dehydration. This<br />
can lead to many disorders such as hypernatremia. We need to make a conscious effort to drink<br />
more water.<br />
Sodium (Na)<br />
Sodium is most often found outside the cell, in the plasma (the non-cell part) of the bloodstream.<br />
It is a significant part of water regulation in the body, since water goes where the sodium goes. If<br />
there is too much sodium in the body, perhaps due to high salt intake in the diet (salt is sodium<br />
plus chloride), it is excreted by the kidney, and water follows.<br />
Sodium is an important electrolyte that helps with electrical signals in the body, allowing muscles<br />
to fire and the brain to work. It is half of the electrical pump at the cell level that keeps sodium in<br />
the plasma and potassium inside the cell.<br />
Conditions of Sodium Imbalance<br />
Hypernatremia (hyper= too much + natr= sodium + emia=in the blood) is usually associated with<br />
dehydration, and instead of having too much sodium, there is too little water. This water loss can<br />
occur from illnesses with vomiting or diarrhea, excessive sweating from exercise or fever, or from<br />
drinking fluid that has too high concentrations of salt.<br />
Hyponatremia (hypo=too little) is caused by water intoxication (drinking so much water that it<br />
dilutes the sodium in the blood and overwhelms the kidney's compensation mechanism) or by<br />
a syndrome of inappropriate anti-diuretic hormone secretion (SIADH). SIADH can be associated<br />
with illnesses like pneumonia, brain diseases, cancer, thyroid problems, and some medications.<br />
Symptoms of Sodium Imbalance<br />
Too much or too little sodium can cause cells to malfunction. Lethargy, confusion, weakness,<br />
swelling, seizures, and coma are some symptoms that can occur with hyper - or hyponatremia.<br />
The treatment of these conditions is dependent on the underlying cause, but it is important for<br />
the healthcare provider to correct the sodium imbalance relatively slowly. Rapid correction can<br />
cause abnormal flow of water into or out of cells. This is especially important to prevent brain cell<br />
damage.<br />
When to stop Salt.<br />
We should get three times more potassium than sodium and this is not the case with over<br />
consumption of salt today. Use more paprika (rich in Potassium) and less salt.<br />
