Hyponatremia results from too little sodium in the blood. Often, blood pressure decreases and not enough blood gets to cells to nourish them. Hyponatremia results from hydration's without electrolytes during prolonged periods of sweating, such as endurance events. Athletes can sweat at a rate of 2.5 liters an hour and lose 115 to 690 milligrams (mg) of sodium, or 288 to 1,725 mg per hour, with each liter. If the athlete, or you!, is following a low-sodium diet, more sodium loss can occur! Muscle twitches may indicate hyponatremia.

Take care to follow hydration guidelines. If exercise last longer than an hour and a half, it may be wise to drink a sports drink with electrolytes such as sodium. If you tend to get hyponatremia, you do not have high blood pressure, and your physician approves,
