    less than 2 glasses?! Even when you exercise?!

    I've probably had about a 1-1.5 litres today and I still feel dehydrated, need to go get a glass in a sec. I couldn't cope on so little water, I get really headachey and horrible.

    74 ounces of water today, or 2.2 liters.
    If you eat a healthy diet, about 20 percent of your water need may come from the foods you eat. If you eat a healthy diet you can drink 59.2 ounces of water today, or 1.8 liters.


    So that comes out about right at 8 glasses, a bit more maybe.

    I'm sticking with the food stanards agency's idea:

    In climates such as the UK, we should drink approximately 1.2 litres (6 to 8 glasses) of fluid every day to stop us getting dehydrated. In hotter climates the body needs more than this. We also get some fluid from the food we eat.

    I try and fill a 2 litre bottle in the morning and drink it throughout the day.

    I know plenty of people who apply that philosophy. Their dogma is something along the lines of "why get sloshed there when you can get mashed before leaving home?"

    yes you are talking about water,
    i can see that, so then also try aromatic water flavours, mineral water drink
    and some great bottled water from the canadian water streams and french alps.!!!

    It really makes no difference at all. I drink when I'm thirsty, I have no idea what that works out to, but I'm just fine. Quite simply, if you are thirsty, have a drink (non-alcoholic, without caffeine ). Sure, if it is really hot or if you are going to do some heavy training then you may want to bring a water bottle to make sure you actually have something to drink, but to be completely honest there is little need to plan the amount of water you are going to aim for during a day. If you don't drink enough, you will get thirsty, and if you drink too much all that happens is that you need to go to the bathroom all the time. The body is very good at regulating the water-salt balance and will do so in the obvious manner if you drink too much.

    Now, what you should watch out for is if you drink vast quantities of tap-water and nothing else. Tho the body is quite capable of maintain its nutritional balance, it does lose salt and acid when you urinate. Thus if you keep drinking vast quantities of water without replacing the salt, it could very well cause you trouble. Botled water is usually spiked with various salts to avoid this problem, but tapwater is not. Its not unheard of that people who freak out about getting enough water per day end up hospitalised due to water poisoning. Also, the kidneys do flush out various poisons, but they also flush out excess water, wether poisonous or not. Drinking far more water than you need does stress your kidneys, and could become a problem in the long run ( tho you would probably have to drink uncomfortably large amounts of water for this to be a concern).

    All in all, you need to replace the water you lose, but there really isn't any need to "cleanse" the body with excess water. Unless you are doing something that really drains you of water ( outdoors sport when its really hot ) most people will spontaneously drink enough to replace the water they lose simply because they get thirsty.

    Just don't force it all down at once.

    A person with two healthy kidneys can rid themselves of about 1.5 litres of water per hour at maximum filtration (other studies find the limit to be as little as 0.9L/hr [1]) . Consuming as little as 1.8 liters of water in a single sitting may prove fatal for a person adhering to a low-sodium diet, or 3 liters for a person on a normal diet.

    I was told that as well - I used to drink hardly anything (I could go almost 2 days before realising I'd not had a drink). I found that filling 500ml bottles and adding squash really helped, because I've never been able to drink water on its own and having a smaller bottle makes it easier to just sip at it throughout the day.

    Is the recommendation of 8 glasses of water a day to stop you becoming dehydrated just a myth?

    I keep hearing people recommend this, but I was under the impression that this was a strange myth with no scientific backing. I was just wondering if anyone could clear this up for me, as I have never even tried to come close to 8 glasses a day.

    These link generally sum up my previous view:

    http://www.snopes.com/medical/myths/8glasses.asp

    However, even if 8 glasses are not needed to stop dehydration, do they have other health benefits?

    Thanks for all your replies in advance!

    Your body is made up mainly of water, so it is common sense to keep it topped up.

    It cleans your system and improves your skin condition.

    Just drink the damn water! :mad:
