Hyponatremia refers to a lower-than-normal level of sodium in the blood. Sodium is essential for many body functions including the maintenance of fluid balance, regulation of blood pressure, and normal function of the nervous system.

It's possible to become deficient in sodium if you sweat too much, like when you over-exert yourself on a sweltering day. You can prevent sodium loss by drinking sports drinks that contain electrolytes.
