What is great about water is how much it helps you when it comes to losing weight and curbing your appetite. It’s true. But is there such a thing as drinking too much water? Actually, most people don’t drink enough water.
ok , so seriously, how much water should you drink in a day?
Stupidly simple question right? How could this be complicated?
Well – there are a lot of very simple, definitive answers for how much water you should drink in a day. And like most easy, simple answers – they’re wrong.
The truth is, the right amount of water for you in a day depends on you – who you are, how old you are, what you do, etc.
So let’s answer those questions, so that you can know how much water you should drink in a day, rather than reading “Get 8-12 glasses a day!” and throwing your computer against the wall in frustration.

Why Do I Need Water In The First Place?
We’re gonna start real simple here. Bear with me.

What you drink doesn’t have to be water.
The Institute of Medicine recommendations and the 8 glasses a day recommendations are for total liquid intake, not just water.
So if you’re drinking fruit juice, or seltzer, or other hydrating drinks, that counts. (Even protein packed smoothies!)

If you’re sick and have a fever, or you’re throwing up, you gotta drink more fluids, because your body is losing more fluids.
Other conditions that require more fluid intake are urinary tract stones and bladder infections.
However, if you have a condition like heart failure or kidney or liver disease, your
