Since only some plants need sodium and those in small quantities, a completely plant-based diet will generally be very low in sodium. The minimum physiological requirement for sodium is between 115 and 500 milligrams per day depending on sweating due to physical activity, and whether the person is adapted to the climate. Note that salt contains about 39.

3g sodium would be about 5. Sodium channels are known to be less selective in comparison to potassium channels. Remarkably, researchers have engineered a highly selective sodium-specific DNAzyme and demonstrated its application in detection of sodium in live cells. However, drugs with smaller effects on sodium ion motion in nerves may have diverse pharmacological effects which range from anti-depressant to anti-seizure actions. Whenever there is an increase in sodium concentration in the blood, the kidney releases most of it in order that there will be enough water for use of the body. But when there is a decrease in its concentration, there is more release of water to store more sodium which the body needs dearly. These fluids, such as blood plasma and extracellular fluids in other tissues, bathe cells and carry out transport functions for nutrients and wastes.
Sodium is also the principal cation in seawater, although the concentration there is about 3. 8 times what it is normally in extracellular body fluids. This ordinarily results in thirst. Severely dehydrated persons, such as people rescued from ocean or desert survival situations, usually have very high blood sodium concentrations. This happens because the kidney is unable to efficiently retain water while excreting large amounts of sodium. Sodium and Potassium in Health and Disease”. In Astrid Sigel, Helmut Sigel and Roland K.
