Use and drink purified water. Generally, we know to drink purified water, but we also need to purify the other water we come into contact with. For instance, we also absorb water through showers, baths, swimming pools, hot tubs, etc. The major pollutant in water is a chemical that was used as a lung irritant in warfare: chlorine. Chlorine is a greenish-yellow, poisonous chemical with a disagreeable odor, but is used by public water works to “purify” municipal water. Tap water contains more unwanted chemicals, radiation, toxins, pesticides, herbicides, and other pollutants than ever before—and the amount varies from town to town. Pollutants use up the body’s nutrients faster than they can normally be re-supplied; this is can be extremely serious for digestive disorder sufferers. Dr. John Andelman, University of Pittsburgh, School of Health researched how chlorine affects us: “During a warm or hot shower, the pores open and the body and skin literally “soak up” the chlorine. Because the body acts like a “sponge” for chlorine, a person is exposed to 6 to 100 times more chlorine and waterborne toxins by taking a shower than by drinking the same water. What’s more, the chlorine gets into the shower steam as chloroform—a toxic vapor—which we breathe in, our lungs absorbing it.” Dr. Kurt W. Donsbach, Ph. D. talks about what chlorine does to the human body. Apparently, the chlorine free radical can modify your DNA. Dr. Herbert Schwartz of Cumberland County College in Vineman, N. J. says that, “Chlorine has so many dangers it should be banned. Putting chlorine in the water supply is like starting a time bomb. Cancer, heart trouble, premature senility, both mental and physical, are all conditions attributable to chlorine-treated water supplies.” Municipal water has other unhealthy elements in it, too, but the chlorine is the worst element. The chlorine is easy to remove with a simple carbon filter for all water outlets. To change the chlorination levels in a swimming pool, look into a salt water system; it can reduce the chlorine content of the pool water by 90 %.
