The Problem With Distilled Water
Distillation is the process in which regular water is boiled and evaporated, and the vapour condensed. Distillation uses the fact that water has a lower boiling point than most solids and contaminants. Impurities are left on the container used to boil the water and the ‘pure’ water vapour goes into another container. This method of making water potable fails to factor in a few things.
Contaminants With Lower Boiling Points
In the event that there are liquid contaminants, pesticides and chemical additives, it is impossible to purify the water through distillation. This is because these substances have a lower boiling point than water—meaning they will evaporate before the water does. This means that the condensed water vapour will still be impure
According to the Safe Drinking Water Act (SDWA) — a Federal law in the USA — a contaminant is any physical, chemical, biological, or radiological substance in water. This means that not all contaminants are necessarily harmful. Distillation does not discriminate between good and bad contaminants; healthy minerals such as potassium, calcium, chloride, sodium, and magnesium are eliminated from the water as well. Some vitamins are also eliminated. These nutrients are very important to your wellbeing. The longer you drink distilled water, the higher the risk of developing mineral deficiencies.
Distilled water is an active absorber; when it is exposed to air, it absorbs carbon dioxide, making the water acidic. This in turn increases the body acidity of the individual consuming the water.
“Distilled water, being essentially mineral-free, is very aggressive, in that it tends to dissolve substances with which it is in contact. Notably, carbon dioxide from the air is rapidly absorbed, making the water acidic and even more aggressive. Many metals are dissolved by distilled water.”
U.S. Environmental Protection Agency
A growing number of scientists and practitioners globally are advocating the theory that accumulation of acid waste products in the body leads to aging and disease. There is much scientific documentation that supports this theory but it is yet to be proven.
Conclusion: It is not a good idea to use distilled water for long periods of time.
