That's your motto, ignoramus. You never look anything up. Because you're an ignoramus.
My niece is a doctor and my mom was an RN.
And yet you're still an idiot.

Hyponatremia -- what is it?
Hyponatremia means a low concentration of sodium in the blood. When it occurs in triathletes, it usually happens during long or ultra-distance races in the heat but may occur anytime. It is estimated that approximately 30% of the finishers of the Hawaii Ironman are both hyponatremic and dehydrated. The longer the race, the greater the risk of hyponatremia.
What causes it?
The exact mechanisms are not fully understood and I won't go into the complex physiologic pathways of sodium and water balance. The simplest answer is that lost sweat (salt and water) is replaced by ingested water (no salt). This dilutes the sodium in the bloodstream, and hyponatremia results. Longer races carry a greater risk of hyponatremia because of the total amount of sweat lost. During exercise in the heat, more salt is lost in sweat per hour than is usually replaced by food and fluids, including sports drinks. Your body can tolerate a degree of imbalance for a short period of time, but it may decompensate if this continues for too long.
Sweat contains between 2.25 - 3.4 grams of salt per liter, and the rate of perspiration in a long, hot race can easily average 1 liter per hour. So, for a 12 hour race, one could lose approximately 27 to 41 grams of salt. If the athlete replaces only the lost water and has minimal salt intake, hyponatremia can result.
Treatment
Minor symptoms, such as nausea and mild muscle cramps, can be
treated by eating salty foods and hydrating with a sodium containing sports drink. More severe symptoms require treatment by qualified medical personnel. If you think you are suffering from hyponatremia or are unsure, seek medical attention immediately.

Probably has something to do with your lack of comprehension skills, combined with your refusal to look things up.
And actually, I understand. It's hard to effectively search information if you are incapable of forming a coherent sentence, and the sentences you do form have nothing to do with the idea you're trying to get across. I have no doubt internet searches or library research is next to impossible for you, thus frustrating. Hence your dependence on urban legend and rumor for your meager store of knowledge.
