How do electrolytes work in our body?

Electrolyte is a substance with free ions that's electrically charged, and conducts electricity. Electrolyte is a medical or scientific term for salt, and specifically ions. Electrolytes can appear in liquid, gel, or paste form. Electrolyte mean that the ion is electrically charged and it moves to a cathode, or anode. Ions that move to cathode are positively charged. Ions that move to the anode are negatively charged.

Athletes know that their body loses salt through sweating, and they know that it's really important to replace it, that's why they drink sports drink during exercising and after exercising to prevent muscle cramps. Humans like us also really need different kinds of salt. We need salt for our body to stay healthy. If we don't provide salt for our body when we really need it, then salt imbalance will occur, and might cause heart and nervous system problems. The foods and liquids we eat and drink contain mineral salts, when they dissolve then they turn into electrolyte in liquid form. They can appear as blood, urine...etc. The major electrolytes in our body are sodium, potassium, chloride, calcium, magnesium, bicarbonate, phosphate, and sulfate. They are important to help our muscle to function properly. Because the electrolytes are electrically charged, so they it sends signals from our brain to our muscle. As I mentioned, some people drink sports drink to prevent from cramps, because sports drink contains salt.

Electrolytes not just does that, electrolytes also keep fluid levels normal in different body compartments. The levels of electrolytes are controlled by the movement of electrolytes into or out of the different compartments. Our kidney is an organ in our body which filters(or we can say "clean") electrolytes from the blood to keep the level in blood constant and balance.

Our body work in a way that keeps water and electrolyte levels just balance. If our sodium level gets too low, then our kidney will produce more urine(which is pee), which lowers the amount of water in the blood. But if your sodium level gets high, the we will feel thirsty, then we will drink a lot. Sometimes too much salt in our body is not so good, but we still need enough of salt in our body.
