1 Sodium plays a large role in fluid balance, with different variations of sodium determining the shift of water by osmosis from one area of the body to another.  Along with chloride and bicarbonate, sodium is important for the proper regulation of the acid-base balance of the body.
Sodium is an essential electrolyte that helps maintain the balance of water in and around your cells. Sodium is important for proper muscle and nerve function. It also helps to maintain stable blood pressure levels. Low blood sodium occurs when water and sodium are out of balance. In other words, thereâs either too much water or not enough sodium.
