Why Drinking Too Much Water Is Dangerous

On January 12, 2007, a 28-year old Californian wife and mother of three children died from drinking too much water. Her body was found in her home shortly after she took part in a water-drinking contest that was sponsored by a local radio show. Entitled "Hold Your Wee For A Wii," the contest promoters promised a free Wii video game machine to the contestant who drank the most water without urinating.

It is estimated that the woman who died drank approximately 2 gallons of water during the contest. When she and other contestants complained of discomfort and showed visible signs of distress, they were laughed at by the promoters and even heckled.

This tragic news story highlights the importance of understanding why drinking too much water can be dangerous to your health.

Whenever you disregard your sense of thirst and strive to ingest several glasses of water a day just because you have been told that doing so is good for your health, you actually put unnecessary strain on your body in two major ways:

  1. Ingesting more water than you need can increase your total blood volume. And since your blood volume exists within a closed system - your blood circulatory system - needlessly increasing your blood volume on a regular basis puts unnecessary burden on your heart and blood vessels.
  2. Your kidneys must work overtime to filter excess water out of your blood circulatory system. Your kidneys are not the equivalent of a pair of plumbing pipes whereby the more water you flush through your kidneys, the cleaner they become; rather, the filtration system that exists in your kidneys is composed in part by a series of specialized capillary beds called glomeruli. Your glomeruli can get damaged by unnecessary wear and tear over time, and drowning your system with large amounts of water is one of many potential causes of said damage.

Putting unnecessary burden on your cardiovascular system and your kidneys by ingesting unnecessary water is a subtle process. For the average person, it is virtually impossible to know that this burden exists, as there are usually no obvious symptoms on a moment-to-moment basis. But make no mistake about it: this burden is real and can hurt your health over the long term.

Forcing your body to accept a large amount of water within a short period of time - say, an hour or two - as several contestants did during the "Hold Your Wee for a Wii" contest can be fatally dangerous to your health. Here's why:

If you force large amounts of water into your system over a short period of time, your kidneys will struggle to eliminate enough water from your system to keep the overall amount at a safe level.

As your blood circulatory system becomes diluted with excess water, the concentration of electrolytes in your blood will drop relative to the concentration of electrolytes in your cells. In an effort to maintain an equal balance of electrolytes between your blood and your cells, water will seep into your cells from your blood, causing your cells to swell.

If this swelling occurs in your brain, the bones that make up your skull hardly budge. The result is an increase in intracranial pressure i.e. your brain gets squeezed. Depending on how much water your drink in a short period of time, you could experience a wide variety of symptoms, ranging from a mild headache to impaired breathing. And as occurred recently in the tragic water-drinking contest, it is quite possible to die if you drink enough water in a short enough period of time.

This information is particularly important for parents to pass on to their children. Foolish water-drinking contests are not uncommon among high school and university students, especially while playing cards.

So how much water should you drink to best support your health?

The answer to this question depends on your unique circumstances, including your diet, exercise habits, and environment.

If you eat plenty of foods that are naturally rich in water, such as vegetables, fruits, and cooked legumes and whole grains, you may not need to drink very much water at all. If you do not use much or any salt and other seasonings, your need for drinking water goes down even further.

Conversely, if you do not eat a lot of plant foods and/or you add substantial salt and spices to your meals, you may need to drink several glasses of water every day.

Regardless of what your diet looks like, if you sweat on a regular basis because of exercise or a warm climate, you will need to supply your body with more water (through food and/or liquids) than someone who does not sweat regularly.

Ultimately, the best guidance I can provide on this issue is to follow your sense of thirst. Some people believe that thirst is not a reliable indicator of how much water you need, since many people suffer with symptoms related to dehydration and don't seem to feel a need to drink water on a regular basis. My experience has been that most people who are chronically dehydrated have learned to ignore a parched mouth. If you ask such people if they are thirsty and would like a piece of fruit or a glass of water, they will almost always realize that they are indeed thirsty.

Some people suggest observing the color of your urine as a way of looking out for dehydration. The idea is that clear urine indicates that you are well hydrated, while yellow urine indicates that you need more water in your system. While this advice is somewhat useful, it is important to remember that some chemicals (like synthetic vitamins) and heavily pigmented foods (like red beets) can add substantial color to your urine. Thumbs down for synthetic vitamins, and thumbs up for red beets and other richly colored vegetables and fruits.

The main idea that I wish to share through this article is to beware of mindlessly drinking several glasses of water per day without considering your diet, exercise habits, climate, and sense of thirst. And when you do find yourself in need of water, remember that you can get it from liquids and/or whole foods.

Water and obesity

I believe you missed one point in this article that more people should realize.

I believe it is probably very common among the obese to eat rather than drink when their mouth gets dry. Eating will temporarily moisturize the mouth with saliva and is my personal cure of choice if I'm not thinking directly about why I am eating. Keeping a bottle of water handy, and conciously reaching for that first when I am tempted to the cupboard or refrigerator has helped me change that and I've lost ten pounds in the last 19 days or so. Can't say if It will make a long term change for me, but I live in hope. Kitty

Water and Obesity

While I agree with Kitty that many people do turn to food when they get thirsty, mistakenly viewing the nagging need for water as hunger, I think she is being quite judgmental to single out overweight people in this. This is a common reaction in many people of differing weights and body sizes and does not in itself cause overweight. Congratulations to her for having lost some extra pounds through substituting water for food and being more aware of her need for water, but to make the statement that obese people eat when thirsty rather than drinking is an ignorant judgment based on opinion.

Water intake & overweight

I have to agree with Kitty in the previous comment. I have been attending Weight Watchers for several months and I've lost 16 lbs. One thing they've talked about is how sometimes overweight folks "confuse" the urge to eat, with an urge for water. The body is sending a signal and often by the time bubbles to the front of thought, we think of it as "Oh, I need food" and we often eat, when in fact we need hydration. I drink 6 glasses a day and I've noticed my hunger cravings have been reduced by at least 50%.
Using the color of your urine as a guide is a good idea too. Almost clear, is well hydrated. More physical activity requires more water.
A toast to healthy drinking! Shelly

water consumption

Dear Dr. Kim:

Please add that over-consumption of water needlessly dilutes the bodies' vitamins and minerals, esp. Vit C and all non-oil based vitamins and minerals.

Too much water

Wow! this is so neat, all these years I have been one that is not into drinking the ten glasses a day that everyone says we should drink... but I have found I am always trying to get my kids to drink lots, i admit, even when they are not thirsty... but then I started thinking about it.. if drinking lots flushes out toxins from your body... then won't it also flush out vitamins? Hm.... well, I think so! Just a thought, obey your thirst, God made it for a reason.

Too much water OR too little

I read this article with great interest.  I'm obese and I don't reach for foods instead of water when I'm hungry.  I'm also an osteopenic hypothyroid celiac with fibromyalgia.  I have been gluten-free for 2 years and despite eating well, I'm not losing weight.  For being 273 lbs at my heaviest, I rarely eat over 2,000 calories, mostly between 1,200 and 1,500.  At one time for over 6 months I exercised daily and was sore daily (I did lose 14 lbs).  My heart palpitated before CD dx, was worse after exercise.  I gave up.  I've incorporated eating more raw food, but also eat warm soups.  Before that, the doc lowered my Synthroid dose to see if it'd help my palpitations. I'd lowered my dose before because I was absorbing better with gf diet.  This was my third time lowering my dose and it was not the charm.  I crashed.  This, at a time when I experienced no power or water for a week during a winter storm.  This, at a time when I'd just sent my husband to work out of state.  While alone I craved yogurt and only drank coffee for fake energy.  I did not have thirst and loved not going pee all the time, esp in the middle of the night as usual.  This was December 2007.  Remember the raw food I was eating?  Well, I've always had a penchant for salty foods (probably because I was malabsorbing because of undiagnosed celiac).  When changing to a more raw food diet, by proxy, didn't eat much sodium.  I found myself binging on potato chips and Lipton's onion dip - very salty!Well, I've since been diagnosed with secondary hyperparathyroidism ... and within the last two months been on quite a learning curve about our kidneys/vascular system and heart health.  I craved the sodium, but didn't drink the water to BALANCE my needs.  Warning!  You can't get back kidney health!  Take care of them and you take care of your heart too!  I am back to drinking 8-10 glasses of water a day, and I monitor my sodium intake via a free online diet site, Sparkpeople.com.  With enough but not too much water, I have been losing weight.  BALANCE IS KEY!  Thanks for the article Dr. Kim.P.S.  My fibro is about non-existent now w/gf diet! 

Weight loss

After reading the article some lights went off. In a nutshell I cut water out and used fresh vedg & fruit as moisture - like monkeys do (smile) - but true.
Lost 30lbs in 8 weeks (lost of hard exercise as well) body fat went from 20% down to 8.7%.

In summary our society has overated the use of water in our diets to being fanatic rather than sensible.
