Water is booming these days!
It's big business.
First - most of the advice you get about
drinking water is dangerously wrong.

We talked about
 the benfits of drinking water here before.

No one really knows for sure exactly how much water you should drink, and the blanket advice we get is pure urban legend!  "Drink 8 glasses a day!" -

Now, that may sound like good advice, but further
analysis shows it's an overly simplified "wives tail."

As recently revealed by the
American Journal of Physiology,
 there is absolutely no scientific evidence to
support the popular 8-glasses-a-day theory.

First, you need to drink water regularly throughout the day. You should, in fact, hydrate every
single hour. (maybe that's where the 8 glasses a day came from? one glass per hour?)  
Many people who simply take up the habit of drinking a glass (or even half a glass)  
every hour notice their energy levels skyrocket.

Why? Because most of us are chronically dehydrated. Signs of dehydration can show up as dizziness,
 fatigue, impotence, hair loss, headaches, low back pain, constipation, and other things as well.
Dehydration has been shown quite clearly to be linked to all of these.  (Merck Manual of Health)

 "How much water" depends on a lot of factors. It depends on your body size, how much you exercise,
the climate in which you live, and more ...

Obviously if you live in a hot climate where you're sweating all the time (a lot of the sweat is invisible -
you don't have to be dripping to be rapidly losing water all day long), you need more - a lot more.
If you exercise even mildly - same thing.

You may think drinking more water by itself is enough, but if you drink too much you can actually
"overdose" on water. It's true, too much water can harm you by either water intoxication 
or by electrolyte imbalance.

See, the more water you drink, the more you need to replace your electrolytes.
So does that mean you need to start drinking fancy sports drinks? No. 
All you have to do is add a tiny pinch of sea salt to every gallon of filtered
drinking water you drink and - voila! - you have all the electrolytes you need.
