Myth #2: You can't drink too much water—more is always better. Fact: It is possible to overdo your water intake and drink more than your body can flush out. This is called hyponatremia (also known as water toxicity), a condition in which sodium levels in the body are dangerously low. Hyponatremia can cause a host of physical symptoms ranging from confusion, nausea, and headaches to convulsions—and can even be fatal in some cases. There are certain people who are more prone to hyponatremia than others, including those with congestive heart failure, kidney failure, or Addison's disease. Endurance athletes are also susceptible, especially novice runners. The good news? If you don't have any of the risk factors mentioned above, water toxicity is usually not a serious concern. This is because in healthy people, the kidneys are able to excrete extra fluids in order to maintain a proper balance of electrolytes.
