Natural water usually contains a number of microscopic contaminants, along with dissolved minerals such as calcium and iron. One way to remove these elements from water is to boil it until it changes to steam, a process known as distillation. When this steam is allowed to cool down and condense into liquid form again, the result is a purified form called distilled water. Distilled water should ideally be nothing but hydrogen and oxygen molecules, with a PH level of 7 and no additional gases, minerals or contaminants.
The distilling process relies on the principle that most solid materials found in water are heavier than the water molecules themselves. When water is heated in a distiller, any dissolved solids such as salt, bacteria, calcium or iron remain solid while the pure water converts to a much lighter steam and is drawn out for condensation. Distilled water has a noticeably bland taste because all of the minerals which give water its flavor have been removed.
Distilled water is safe to drink, but it is used more often for research purposes where water purity is essential or industrial uses where mineral deposits can cause damage over time. Distilled water may also be used in steam irons to prevent calcium build-up, but this requirement has generally been relaxed in recent years. Certain baby formulas may use distilled water as a mixing liquid as well. Pediatric bottled water formulated with additional electrolytes may use a distilled water base as well.
There is some controversy over the use of distilled water as a healthier alternative to tap, spring or purified water. One camp suggests that distilled water is beneficial since it contains no impurities or minerals and helps flush away excess minerals and toxins from the body. Another camp believes that distilled water leaches essential minerals from the body and could leave teeth vulnerable to damage. Distilled water does not contain sodiumfluoride, unlike many municipal water systems.
There is some evidence that distilled water does absorb carbon dioxide when exposed to air, and this could conceivably lower the pH to a more acidic level. This increased acidity can in turn create more health problems. Proponents of distilled water suggest that humans receive far more minerals and nutrients from food than water, so the effects of distilled water on the body should be minimal at best. The flavor of distilled water can be improved with natural fruit juices or essences, if necessary.
Distilled water can be purchased in a number of grocery and retail stores, usually in one gallon containers. It is important to check the label when shopping for bottled water of any kind, since distilled water has a distinctive taste compared to spring or purified water. Some bottled waters use distilled water or deionized water as a base, with different minerals added for taste.
I would recommend this book by Dr. Allen Banik, "The Choice Is Clear". It's a quick and informative read regarding the pros and cons of drinking distilled water. Most health food stores have it in stock.

I am a certified Health Consultant, and I've done the research. About 15 years ago my husband and I were experiencing multiple health issues such as arthritis, acid reflux, etc. We were determined to take charge of our own health -- drug free! After reading the studies of scientist Dr. Norman Walker and other reputable sources on the subject of distilled water, this was the best change we made.
We've been drinking distilled water all these years and have absolutely no joint pain, arthritis, acid reflux, etc. It's true that distilled water has a ph of 6.2 -- so what? If you don't think your mineral intake is up to par, then add a few drops of minerals, fresh lemon, organic apple cider vinegar, etc. Just keep in mind, coffee, tea, soda, etc. have a range of 2 to 5! Talk about dangerous! Relax and enjoy the benefits of distilled water!

This my third week of using distilled drinking water, me and children felt some unusual pain in our abdomens. Does distilled water has something to do with it? I've been using mineral water for almost 25 years now and felt good about it, but when i shifted to distilled, some abnormalities occurred. i hope this is just a matter of adjusting to our body chemistry.

I've been drinking distilled water every day. I use a water distiller that cleans the tap and once it has finished the process of distilling I pour it into one of two gallon jugs I have. These jugs are always on my kitchen counter and sit in the sun, the only changes that occurs with them are the refilling and emptying of the water for drinking purposes. Until recently I thought this was the best water.
My problem started two days ago. At first I felt a slight pain for a couple of minutes when I drank distilled water. I thought I had a cold but it was unfortunately a problem far greater. Soon when I drank distilled water, my whole body had a painful seizure for hours.
I went to the doctor to ask what the problem was and they thought it was a mold or something that had been growing in the water jugs. They tested the jugs and they came back negative of anything of the sort. My doctors kept on searching for answers because the symptoms were recurring until they finally found the reason.
Apparently the water is too pure and my body had begun to develop a defensive reaction each time I drank purified water. Soon my body began rejecting even he tap water I drank and the water in your blood. I am telling you this as a warning. I am expected to die soon because of dehydration. Basically my body is rejecting itself. I hope my experience helps others.

Drinking distilled water is actually causing relatively more cellular damage than non distilled water.
When you consume distilled water your cells want to create equilibrium. Your cells have a much lower concentration of [H2O] than the distilled water. The water will then diffuse into your cell trying to make equal concentrations of [h2O] in both your cells and the water just consumed. This process is call osmosis. Your cell will burst trying to intake the large amount of water.
Your body will then spend more energy trying repairing the damaged cells. The best liquid to consume to prevent cell damage or the opposite (loss of water in cells caused by drinking something with a lower concentration of H2O like coffee) is Gatorade.
Gatorade or Powerade are both formulated to have the correct concentration of water that your cells will need without extra energy being spent.

One very important thing to remember is that distilled water is essentially pure, which means it returns to being a primary vector for disease if mishandled. Tap water left out for an hour is quite safe to drink. Distilled water left out for an hour isn't terribly dangerous, but bacteria will have colonized it. Give it a day and vast blooms of bacteria, algae, and mold can take root.
Waste water from a dehumidifier is essentially distilled water, and can be used as such. However, remember what I said earlier about the lack of bacteriocidal properties: if you wish to drink from your dehumifier, you must keep it hospital-clean. Wash the collector bucket and cooling coils thoroughly with vinegar or alcohol, allowing them to dry fully before use. Once you collect this water, it should be kept in a sealed container in order to prevent contamination as well as evaporation.
Most people don't truly need distilled water, but for those who do, my pointers will save you from allergies and sickness.

I just bought a distiller. I have thought about it for years. I was worried about spending the money. I wish I would have done it earlier. I found sone from $79 on up. Do a search.
I could not believe the nasty looking and smelling stuff that one gallon of distilling left in the machine. My wife quickly changed her mind. We will only use distilled water for drinking or cooking.
Now. I am angry about all the propaganda for tap water. We have public water. I felt better as soon as I started drinking pure water, and it tastes much better to me.

I drink distilled water, have been for 3 years. Arthritis & delicate stomach issues have stopped. I am not putting arsenic & chemicals the water company add to "clean" tap water into my body. I will never drink tap again. Distilled is what God gave us originally, when rain was safe to save in barrels & drink...ask your grandparents what they drank years ago...

Distilled water is also cut with 50% alcohol in order to make a cleaning solution good for cleaning LCD displays (such as those used in laptops) and as well TV and Monitor screens, so as not to wipe the chemicals in the water onto the screen and smear it with lines.
Additionally, some of the chemicals in non-distilled water can hurt an LCD display when wiped thereupon.

Distilled water is by far the best choice if you have concerns about the unreliability of bottled waters or contamination of tap water. The trace nutrients can easily be replaced by by dietary means.
For anyone who chooses to comment on the contribution of the process to "global warming": I urge you to do your homework where the relationship between global temperatures and co2 are concerned. I suggest you go back more than two decades, and avoid sources with a vested interest in perpetuating the current global warming ideology fads.
Stop letting other people do your thinking for you.

i would like to know if you could make your own distilled water?
If you can boil water you can distill it theoretically.
You can also buy distillers from retailers.
My dehumidifier produces gallons per day of what I assume is identical to distilled water, only it's "condensed" water. Is this true?
Condensed water does not suggest that the water is distilled as there could still be other contaminants based on how and where the water condenses.
If something is acidic, it means that the pH has been lowered below pH 7, not raised. The opposite is true for basic (or alkaline) solutions. To truly be acidic, carbon dioxide requires high pressure and low temperatures to be dissolved in water and form carbonic acid. Otherwise, the process would take longer to occur. Look up Henry's law. This is how we have carbonated beverages (i.e., Pepsi), which are more acidic than distilled water.
You are right about the pH. You are wrong about distilled water not absorbing CO2, I am well aware of Henry's law and it hold true for carbonated beverages but the amount of CO2 is so great that pop is supersaturated and the gas leaches out at ambient pressure.
CO2 will readily dissolve in distilled water (or any water, but more so in distilled because it's 'empty' water). This can be proven. Add phenolphthalein indicator to distilled water. Let's presume the pH was 7 or just slightly below. the indicator should be a slight pink colour. If you simply exhale over an erlenmeyer flask and swirl the water, the indicator will go clear after a matter of seconds indicating a drop in pH. Oceans absorb tons of the atmosphere's CO2 and they contain many salt or ions. Distilling water will amplify this effect.
Regards.
p.s. I will not drink distilled water personally. The best is filtered water from reverse osmosis or activated carbon.

Distilled water is highly acidic and should not be used for drinking. Did you know that it takes 8 fresh gallons of water to make just one gallon of bottled water? That is such a waste, also the petroleum that it takes to make the bottles and transport them is bad for the environment. The water is not any better than tap water and it is toxic sitting in those plastic bottles. The only solution is to make your own healthy water right from your own tap. Re-Use and Refill, save your health and the environment at the same time. stop buying corporate water! Stop getting ripped off by these bottling companies and take control of your own water supply.
