Sodium levels in the body are partly controlled by a hormone called aldosterone, which is made by the adrenal glands. Aldosterone levels tell the kidneys when to hold sodium in the body instead of passing it in the urine. Small amounts of sodium are also lost through the skin when you sweat.

Answer: Because your body continually monitors blood volume and sodium concentration. When either becomes too high, sensors in the heart, blood vessels, and kidneys detect the increases and stimulate the kidneys to increase sodium excretion, thus returning blood volume to normal.Sodium levels are regulated by the kidney and adrenal gland. The adrenal gland produces a hormone called aldosterone that tells the kidneys how much sodium to retain. When either sodium or potassium becomes unbalanced, the kidney may expend the other electrolyte to maintain a balance.

Hope this helps have a awesome day/night❤️✨
