Why avoid drinking chlorinated tap water? Chlorine, an element, is a toxic chemical. It has been associated with a low thyroid function and the development of arteriosclerotic plaques or hardening of the arteries. 

Body toxicity can accumulate from internal consumption and external exposure in high amounts over a period of time. Some substitutes would be drinking distilled or spring water instead of using tap water. Mountain valley spring water is the best from my research. Buy a chlorinating filter for the showerhead. If possible, use a salt water pool instead of a chlorinated pool.
