Myths about How Drinking Too Much Water Can Actually Harm You

Available for Interviews: Dr. Karyn Eilber

Karyn Eilber, MD, is a board-certified urologist, an associate professor of urology & OB/GYN at Cedars-Sinai Hospital in Los Angeles, and is an expert in women’s health and men & women’s sexual wellness.

What Dr. Eilber Can Say on:
You need to drink at least eight glasses of water a day to be healthy. You’ve heard that so many times, it must be true? But is it?

  • It’s not good to be chronically dehydrated, but being over-hydrated just makes you pee more.
  • Shockingly there is no science between drinking eight glasses of water daily. Your pet goes to their drinking source when thirsty, drinks, then walks away. Your vet has never told you to make your dog drink eight bowls of water a day, so why do humans need eight glasses of water?

  • The best indicator to drink is feeling thirsty. But if you have a chronic dry mouth, the color of your urine can indicate your hydration status. The more your urine is clear like water, the more hydrated you are. The darker and more strong smelling your urine is, the more dehydrated you are. 
  • The more you drink, the more you need to urinate–this isn’t good news for people with overactive bladder who have urinary frequency and urgency
  • Drinking too much water can dilute your electrolytes. In an extreme case, too low sodium can result in seizures.

So while you don’t want to be chronically dehydrated and put yourself at risk for things like kidney stones, you don’t need to excessively drink water because that comes with its own problems.
