Sodium is a mineral that your body must have in order to function properly. Sodium (Na), along with potassium (K), is an electrolytic compound necessary for humans to regulate the physical fluids system. Many processes in the body, especially in the brain, nervous system, and muscles, require electrical signals for communication. Sodium: The major positive ion (cation) in the fluid surrounding cells in the body. Electrolytes help with muscle contraction and afferent neuron transmission.

Increasing your consumption of foods high in potassium and decreasing your salt intake can flush out sodium. A decrease in blood sodium concentration, also called hyponatremia, can cause seizures, while low potassium levels in the bloodstream, or hypokalemia, can lead to heart problems. The chemical notation for sodium is Na+. When body sodium is high, your kidneys excrete the excess in urine. Sodium is one of the many important electrolytes in the body. Food Sources.

Healthy kidneys maintain a consistent level of sodium in the body by adjusting the amount excreted in the urine. Sodium levels are influenced by the sodium content of our diets and how much we lose through urination and sweat. Individual differences in sweat sodium losses Sweating is the main way athletes lose sodium and fluids during exercise. HealthCentral says that sodium is an important determinant of the volume of blood in the body and is an important factor in determining blood pressure. Your body keeps sodium in … The body uses electrolytes like sodium, potassium, chloride, and bicarbonate to create the electrical flow required for nerve transmission, muscle contraction, fluid balancing, pH balancing, and kidney functioning. Learn who is at risk for low sodium levels and the dangers of this condition. The body obtains sodium through food and drink and loses it primarily in sweat and urine. Sodium (Na +) is the most abundant cation in extracellular fluid.Sodium aids in osmotic pressure, renal retention and excretion of water, acid-base balance, regulation of other cations and anions in the body, plays a role in blood pressure regulation, and stimulation of neuromuscular reactions. The effects of sodium in the human body include maintaining electrolyte balance in the bloodstream and the proper working of the nervous and muscular systems. It is because of this that the blood pressure levels in the body are stabilized. Sodium is a mineral element which is an important part of the human body. 1 Potassium is found in vegetables, fruit, seafood, and dairy products. Sodium channels are known to be less selective in comparison to potassium channels. People with low levels of thyroid hormones may also experience low blood sodium levels.
