How is it possible to drink too much water?
Dietitians constantly remind us that drinking enough water is absolutely vital in order for our bodies to function properly. And it is—unless you drink too much of it. Though most people look out for the signs of dehydration, overhydration is equally as dangerous. Drinking too much water can result in water intoxication, also known as hyponatremia, causing the inside of cells to flood due to abnormally low sodium levels in your bloodstream. In severe cases, water intoxication can lead to debilitating health problems such as seizures, coma, and even death.
You NEVER leave the house without a water bottle and constantly have one in hand
If you carry around your water bottle all day and immediately refill it when it depletes, you may be drinking too much water. Constantly adding water to your body can result in low sodium levels in your blood, which can cause all of the cells in your body to swell. According to Tamara Hew-Butler, PhD, an exercise science professor at Oakland University in Rochester, MI, this can become particularly dangerous when your brain starts to swell. “Your brain can only swell about 8 to 10% before it reaches the skull and it pushes your brain stem out,” says Hew-Butler.
