Water: How Much Does a Body Good?


You lug around the water bottle – from home, to work, to the gym – gulping down enough H²O to sink a ship. As the tidal wave slashes around in your stomach during your evening jog, you begin to wonder if you really need to drink two gallons of water a day.

Water flushes toxins from the system, helps your body to maintain a regular temperature, and transports nutrients to your cells.

Of course, if you Google how much you really need to remain healthy, you’ll discover numerous answers, each indicating a different amount.

When it comes to understanding water consumption, answers can be as challenging to come by as why a toddler hates candy. Even Mayo Clinic says this question is one with no easy answer, because the amount a person needs will vary depending on a variety of circumstances. For instance, a 150-pound woman who runs four days a week in the hot Florida sun will require a different amount of water per day to stay hydrated than a 150-pound sedentary woman living in Fargo, North Dakota.

Water is critical to a properly functioning body. It flushes toxins from the system, helps your body to maintain a regular temperature, and transports nutrients to your cells. Get too little and you can suffer from headaches, lack of energy, and, at its worse, fainting or death.

While a one-size-fits-all plan doesn’t work, the Institute of Medicine suggests about 2.2 liters, or 9 cups, of water for women each day, which is close to the “8 glasses a day” rule. Some experts determine water consumption by a person’s weight. Personal trainer and founder of iBodyFit.com, Franklin Antoian, suggests adults drink half of their body weight in ounces; for example, a 150-pound person would consume 75 ounces of water per day, just a bit over the 2.2-liter rule.

    There’s an awesome website called findaspring dot com. You may be able to locate a FREE spring water site on the map. It’s worldwide. It’s awesome water…and it is supposedly tested frequently by the town or county it is near. Try it.
    If not, distilled is the best. I know it comes in plastic, but a naturopath told me that as long as you buy it from a store that has a quick turn around on their water sales, and if you don’t store it for a long time, it would be okay.

    I know I do not get enough water, Especially since I am pregnant! My chiropractor says if I am thirsty that means I am dehydrated already. I should drink water before I become thirsty. Not sure if its true or not.

    water is the best drink for everyone , Water has no replacement .But I meet same sites that warn about the use of bottled water, how dangerous plastic is to our health and that really concerns us, but my husband came in touch with a wonderful product his name is Vivatap ,filters for tap water purification( or water improving agent) it is a really easy and very healthy product and I am amazed .This natural product removes instantly chlorine from the water it removes bacteria from the water ,it adjust the PH value to a healthy level between 7.5-8.5 and adds healthy minerals like calcium and magnesium to the water. You only had to do is to added a one sachet in a bottle or jug of tap water 0.1-0.2 litters and after 5-10 min is ready to drink.

  15. My doctor said that I should drink half my weight in ounces of water per day. So If you weigh 150 lbs then you should drink at least 75oz of water per day.

  16. Ralf says:

    Simple rule: 30-40ml per kg bodyweight per day. If you measure your weight in stones and pebbles you need to find the conversion.

    You also need the electrolytes, or you get what is called water poisoning. Happens to athletes who just drink water.

    Potassium keeps your water within the cells. It is found in fruits.
    Sodium keeps the water between the cells. It is found in salt.
    If you need to cut down on sodium try to cut down on artificial sweeteners, which contain sodium. The Chlorine contained in salt is needed by your stomach to make stomach acid to kill bacteria and parasites and to break down protein.
    To help the stomach doing that don’t dilute your food with a drink during the meal. Instead drink half an hour before the meal, and then again an hour after the meal.

    Water is life. Observing simple rules can save you a medical bill and discomfort.

  20. Carey says:

    A number of nurses have told me that the urine test (how clear/dark it is) is an excellent measure of how hydrated you are. If it’s perfectly clear, then you are 100% hydrated, but a little tinge of yellow means that you are close enough that your hydration level is healthy.

    Also, don’t forgot your electrolytes, especially if you decide to increase your water intake from your norm. You may end up with headaches or dizziness. If you normally have a low sodium diet, you may need to supplement with salt (which is an electrolyte; I recommend sea salt) or some other kind of electrolytes.

  21. Carey says:

    That could be a sign of diabetes or another issue related to the pancreas… recommend getting your blood sugar tested. (And keep drinking water, of course.)
