Chlorine, Cancer and Heart Disease
“We are quite convinced, based on this study, that there is an association between cancer and chlorinated water.” Medical College of Wisconsin, Senior Research Team
The addition of chlorine to our water began in the late 1800s and by 1904 was the standard in water treatment, and for the most part remains so today.
We don’t use chlorine because it’s the safest or even the most effective means of disinfection; we use it because it is the cheapest. In spite of all our technological advances, we essentially still pour bleach into our water before we drink it. The long-term effects of using chlorinated water have just recently been recognized.
According to the U.S. Council of Environmental Quality, “Cancer risk among people using chlorinated water is as much as 93% higher than among those whose water does not contain chlorine.”
Dr. Joseph Price write a highly controversial book in the late sixties titled ‘Coronaries/ Cholesterol/ Chlorine’ and concluded that “nothing can negate the incontrovertible fact, the basic cause of atherosclerosis and resulting entities such as heart attack and stroke, is chlorine.” Dr. Price later headed up a study using chickens as test subjects, where two groups of several hundred birds were observed throughout their span to maturity. One group was given water with chlorine and the other without. The group raised with chlorine, when autopsied, showed some level of heart or circulatory disease in every specimen, while the group without had no incidence of disease. The group with chlorine under winter conditions, showed outward signs of poor circulation, shivering, drooped feathers and a reduced level of activity. The group without chlorine grew faster, larger and displayed vigorous health. This study was well receipted in the poultry industry and is still used as a reference today. As a result, most large poultry producers use dechlorinated water.
“We are learning the hard way that all the time we thought we were preventing epidemics of one disease, we were creating another. Two decades after the start of chlorinating our drinking water the epidemic of heart trouble and cancer began.” Dr. Joseph M. Price
There is a lot of well-founded concern about chlorine. When chlorine is added to our water, it combines with other natural compounds to form trihalomethanes (chlorination byproducts), or THMs. These chlorine byproducts trigger the production of free radicals in the body, causing cell damage, and are highly carcinogenic. “Although concentrations of these carcinogens (THMs) are low, it is precisely these low levels that cancer scientists believe are responsible for the majority of human cancers in the United States.” The Environmental Defense Fund. Chlorine is also suspected of contributing to hardening of the arteries, the primary cause of heart disease.
Simply stated, chlorine is a pesticide, as defined by the U.S. EPA, who’s sole purpose is to kill living organisms.
When we consume water containing chlorine, it kills some part of us, destroying cells and tissue inside our body. Dr. Robert Carlson, a highly respected University of Minnesota researcher who’s work is sponsored by the Federal Environmental Protection Agency, sums up by claiming, “the chlorine problem is similar to that of air pollution” and adds that “chlorine is the greatest crippler and killer of modern times.”
Breast cancer, which now affects one in every eight women in North America, has recently been linked to the accumulation of chlorine compounds in the breast tissue. A study carried out in Hartford Conneticut, the first of it’s kind in North America found that “women with breast cancer have 50% to 60% higher levels of organochlorines (chlorination byproducts) in their breast tissue than women without breast cancer.”
One of the most shocking components to all of these studies is that up to two thirds of our harmful exposure to chlorine is due to inhalation of steam and skin absorption while showering.
A warm shower opens up the pores of the skin and allows for accelerated absorption of chlorine and other chemicals in water. The steam we inhale while showering can contain up to 50 times the level of chemicals than tap water due to the fact that chlorine and most other contaminants vaporize much faster and at a lower temperature than water. Inhalation is a much more harmful means of exposure since the chlorine gas (chloroform) we inhale goes directly into our bloodstream.
When we drink contaminated water, the toxins are partially filtered out by our kidneys and digestive system. Chlorine vapors are known to be a strong irritant to the sensitive tissue and bronchial passages inside our lungs. It was used as a chemical weapon in World War II. The inhalation of chlorine is a suspected cause of asthma and bronchitis, especially in children, which has increased 300% in the last two decades.
“Showering is suspected as the primary cause of elevated levels of chloroform in nearly every home because of chlorine in the water.”Dr. Lance Wallace, U.S. Environmental Protection Agency.
Chlorine in shower water also has a negative cosmetic effect, robbing our skin and hair of moisture and elasticity, resulting in a less vibrant and youthful appearance. Anyone who has ever swam in a chlorinated pool can relate to the harsh effects that chlorine has on skin and hair. What’s surprising is that we commonly find higher levels of chlorine in our tap water than is recommended safe for swimming pools.
Aside from all the health risks related to chlorine in our drinking water, it is the primary cause of bad taste and odour in drinking water. The objectionable taste causes many people to turn to other less healthful beverages like soft drinks, tea or other sweetened drinks. A decreased intake of water, for any reason can only result in a lower degree of health.
The good news is that chlorine is one of the easiest substances to remove from our water. For that reason it logically should serve its purpose of keeping our water free from harmful bacteria and water borne diseases right up to the time of consumption, where it should then be removed by point-of-use filtration.
No-one will argue that chlorine serves an important purpose and that the hazards of doing away with chlorine are greater than or equal to the related health risks. The simple truth is that chlorine is likely here to stay. The idea that we could do away with chlorine represents a very real and serious threat to our health and should be removed in our homes, at the point of use, both from the water we drink and the water we shower in.
