Normal sodium levels in the body typically range between 135 and 145 mEq/l. This range is crucial for various physiological functions, including maintaining fluid balance, transmitting nerve impulses, and regulating muscle function. Sodium is an essential electrolyte that helps control blood volume and pressure, as well as the overall osmotic environment of body fluids.

Values lower than this range may indicate hyponatremia, which can lead to serious neurological issues if not corrected, while levels above this range may indicate hypernatremia, which can also cause significant complications. Therefore, the established normal range of 135 to 145 mEq/l is important for health professionals to monitor and assess, as it reflects the body's electrolyte balance and overall homeostasis.
