Drinking Water - Truths and Myths


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.

    I agree with you. We should not drink like 50 gallon of water a day but most people need to drink more than the 6-8 glass a day to be healthy and feeling good.

    Agreed, it's important not to overdose on water, but drinking more water has fantastic health benefits, and as long as you can put up with the increased frequency of going to the toilet it's got to be worth a try.

    Refreshing to know that I don't need to drink all 8 glasses of water a day, having had a gastric bypasss in 2001,  I still drink and eat small amounts and water isn't one of my favorite things but I now believe that I do drink enough after reading your article and being on certain meds I need to drink some water so I don't get constipated from meds and iron intake.

    Im also glad I read this, my son is a bodybuilder and he can come home from after a great workout from the gym and down 2 gallons of water in like 10 minutes and it had me concerned so im going to have him read this article as well about overdosing on water, wow the things you can overdose on whom would have ever thought water? Another stress im facing now is hair loss with 4 family members only one of which is blood related and all are females in there early 20's losing large patterns of hair something isn't right and even our dermotologist stated they are seeing more of this hair loss in young females in our area of North East Pa. locally any thoughts on this Dr. G?
     
    Please help a mom never stops worrying especially when it's your own children. If so can you please email me, my daughter is presently recieving shots to the spots that their isn't any hair and my daughter-in-law is now starting steriods orally from same Dr.s office. Im puzzled as for the other family members not quite sure treatment they are seeking but this has all just started in the last 4 months with my daughter-in-law noticing a major lost just last week.

    Would appreciate any help you can give. Thanks Ann Marie
