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 essential, but too much can cause serious problems. Your body needs sodium for many basic processes essential to life. It helps your muscles function, allows your nerves to send impulses throughout your body and helps regulate the balance of fluids in all of your tissues.or example, when water is scarce, sodium helps retain water in your tissues, preventing dehydration. If you consume too much sodium, however, this can upset your fluid balance and potentially lead to long-term health problems.
