Almost all of our water contains minerals - sodium, potassium, calcium and magnesium etc. Most treated water also contains numerous chemical compounds some of which smell and detract from taste. 'Hard Water' is water that contains excessive amounts of minerals such as calcium and magnesium. The effect of hard water is that it is difficult to lather and rinse and will commonly cause scale formations that are likely to result in damage to plumbing fixtures and fittings.
Hard water is not necessarily dirty water but it will often contain other contaminants such as iron, copper and manganese - all of which cause unsightly staining of bathroom and laundry fixtures and fittings.
So many common illnesses can be prevented and greatly reduced by an increased intake of healthy water. Headaches, hypertension, back pain, arthritis, ulcers, asthma, morning sickness, fatigue and metabolism can all benefit (and in many cases be prevented) by regulating the body's natural fluid levels.
The best way to prevent, help, overcome and, in many cases, eliminate illness is to give the body purified water. With the proper intake of healthy water, and the right minerals and nutrients, the body can overcome many challenges.
